2。在运输或解除人类防御门之前,必须仔细审查和接受组件的质量。当人们进入该领域时,他们应将组件提交给工厂证书(混凝土测试块的强度报告),并在自我检查合格的组件上盖上“合格的”密封。

评论和接受内容主要包括组件的具体强度以及组件的外观质量。检查具体强度的工作主要是检查混凝土测试块的测试报告,以查看其强度是否满足要求,运输和提升要求。检查组件的外观是查看组件是否具有裂纹或裂纹宽度,混凝土密度(蜂窝,孔和肌腱),并且形状的形状尺寸偏差满足要求。

3。混凝土组件的安装质量必须满足以下要求:

1)保证组件在举重中不断破裂。为此,组件的具体强度不应低于设计强度水平的70%。

The pipeline between the valve and the wall and the top is welded. The proximal surface of the inside of the human defense structure should not be greater than 200.

3. Enter the water supply pipeline of the civil defense. The front of the valve should be used in a hot -dip galvanized steel pipe or a steel plastic composite pipe.

7. Fire hydrant boxes on both sides of the air wall, door frame, and civil air defense wall can only be packed.

6。其他预防措施

1. The exterior wall intersects with the column. Although the column has no anti -seepage requirements, it belongs to the peripheral structure. It belongs to the human defense protection zone naturally to meet the anti -seepage requirements.太容易了。

2. Steel modeling workers are not too economical to prevent concrete, not to mention that the quality of engineering is so high from the outside to the inside. The steel mold sewing leakage is not easy to solve. Your trouble and quality of human prevention and quality are great. The edge of the water stop to the edge of the tie rod must not be less than 3 cm, the thickness is not less than 3 mm, and the double -sided welding is welded. The weld is smooth and smooth. Add cylindrical wooden match to the exposed area, remove it after removing, and block it with waterproof materials. (There are regulations in the specifications, and there are big pictures)

3. The wall height is 5.4 meters. It must be poured at a time. It is not advisable to keep the horizontal construction seam. If the construction seam process will be more complicated, the cost will increase, and the sequelae will be more.本质

4. One level must be improved, which is the requirements of norms. (However, you can make supervision and owners recognize to prepare for the final account claims)

5. It is best to use beams, plates, columns, and walls to avoid a series of troubles and sequelae caused by construction seams. If the process is not available or the conditions are not allowed, I personally think that it should be left under 30 cm.

6. Do it if you want to do it according to the specifications. Avoid that there are no problems in the future, and eat a dumb loss.

7. Finally, I will tell you some of my experience: Doing the construction plan must be done, because many engineering volume is required to be calculated according to the construction plan. For example, in the earth and stone projects, the mechanical specifications and quantities used in the plan must be clearly described. For example, if an excavator, one more, one more mechanical entry and exit fees. The actual amount of earthquakes is higher than the budget. If you have a scheme approved by the owner, you can calculate it according to the plan.

(3) Common problems and solutions during construction

The requirements and protection of the combat reserve of civil defense engineering determine its technical requirements and construction techniques different from ordinary basement during the construction process. Because the construction unit of the person in charge of the person in charge does not know much about the construction technical requirements, many quality problems occur during construction. Here are several common problems in the construction of civil air defense engineering, as well as solutions.

First, people's defense thresholds of reinforcement.

1. The threshold for ordinary people's defense

The threshold of ordinary people's defense door requires 150mm or 200mm above the building ground (determined according to the model), and the threshold should be tied in place before the concrete of the pouring bottom plate; when pouring the bottom plate concrete, the threshold must be left without pouring. In actual construction, the often occurring situation is that before the pouring bottom plate, the threshold steel bars are tied to meet the requirements of the construction specifications. However, after the bottom plate is poured, the size of the reinforcement of the threshold does not meet the requirements, and the threshold stirrup deforms seriously. The reason for this problem is that when the construction workers step on and pour the bottom plate concrete, the concrete is stamped on the threshold reinforcement, causing the sinking and deformation of the threshold reinforcement. To prevent this kind of problems, it is unable to achieve an effective purpose based on the oral explanation of the on -site technology and management personnel, because the specific construction operations are on -site workers, and the technical and managers often cannot implement the construction requirements to every drying. Living workers. The simple and effective method to prevent this problem is: take 2 steel bars that grow on the size of the door hole and welded on both sides of the threshold stirry, and put it on the main band of the bottom plate. This can prevent the threshold from being trampled down and reduce the deformation of the threshold. If the bottom plate is poured, the problem has occurred, what should I do? If the threshold muscles are trampled down, a "U" type set of various "U" types should be welded on the original stirrup. If the threshold leakage occurs, it can only be treated with "gluten" measures.

2. Living threshold

Living thresholds for the defense of livers are generally applied to the door of the car entrance, such as GHSFM4025, GHSFM6025 and other models. The advantage of using the threshold of the live -type people's defense is to facilitate the usual car entry and outbound, and facilitate the maintenance of the door of civil defense; Similarly, many construction units and even design units do not understand the practices of living -type people's defense doors. Therefore, problems are often found in the biomedical threshold during construction. The following schematic diagram is the practice of living thresholds (no earth covered) in the Shenyang area:

2. Reserve of ventilation short tube

The ventilation short tube appears in the engineering function as a personnel bunker project. Its role is to connect ventilation pipes on the air wall, anti -virus wall, and protective partition wall to achieve the effect of protection. In the construction of private defense engineering, the ventilation short pipes are omitted, there are no closed ribs on the ventilated short pipe, and the lack of the size of the ventilation short tube highlights the size of the wall.

As long as the problem of ventilation short pipe omissions, as long as the quality supervision procedures are required to report the ventilation short pipes when reporting to the wall to prevent the wall; in most cases, people who bind steel bars, template installations and ventilation short pipes are not in the same batch of batch People, even if they repeatedly emphasize that the ventilation short pipe must be installed and then combined with the wall, there will often be omissions of ventilation short pipes; therefore, when the wall part of the wall is monitored, it is necessary to check whether the ventilation short pipe is installed in place. The short tube is not installed, and the part is not accepted.

The problem of non -ribs on the ventilated short tube is mostly because the construction personnel do not understand the role of setting up the densely closed ribs, and believe that the inner wall does not have a problem of leak -proof. Therefore, it is necessary to emphasize the role of closed rib protection and confinement in the bottom of the construction technology.

The ventilation short pipe is directly connected to the duct, which is equivalent to part of the duct. It must be reserved in the steel bars of the wall before the wall model of the wall. The air duct connection. Many construction units confuse the ventilation short pipes and protective steel sleeves. They believe that the two are the same thing, but the diameter of the ventilation short tube is larger. In some non -defense professional ventilation installation teams construction, it is often found that when ventilating pipes pass through the ventilation short pipes, they often pass through the ventilated short pipes. Therefore, at the technical intercourse before the project starts, we must emphasize the role and specific practice of ventilation short pipes to technicians responsible for ventilation.

Third, the problem of pulling bolts of the air -to -air wall, anti -virus wall, and protective partition wall.

The air defense engineering space, protective partition walls, and anti -virus walls have anti -toxic requirements. Therefore, when the steel bars of these walls are used, the template "tensor" or the tensile bolt needs to be set up with a closed loop. When some construction units use wooden templates for these walls, in order to save costs, the pairing bolts used by supporting molds not only have a closed loop, but also use the "PVC" sleeve outside the pull bolt. Later, the pull bolt was removed from the wall. In this way, these walls of civil defense can be described as "sores and holes", which has completely lost the role of protection. Because the supervisors did not synthesize the anti -wall of the wall, the civil air defense wall did not synthesize, so when this problem was discovered, many situations were that the wall concrete had been poured.

once a person's anti -wall is covered with holes, it is difficult to remedy. At present, it can

The provided reference scheme is to break and remove the "PVC" sleeve in the hole, and then pour fine stones into the pore eye to expand concrete. This solution is very troublesome to implement, so it is best to take everything to avoid this quality accident.在人防墙体钢筋的绑扎施工时,可以在现场召集一下监理人员、施工技术负责人和负责模板工程的带班班长,把对拉螺栓的要求强调一遍,这样基本可以杜绝这个问题的发生。

人防工程的施工专业性很强,在每个分部、分项工程的施工中都或多或少地发现过施工问题,因此,只有不断总结经验教训,避免以后施工中再次发生同样的错误,才能保证人防工程的建设质量越来越好。
