How many miners are needed to lay drainage pipes in the hospital

1. seven

2.

It takes five workers to dig a 50 meter trench in 50 hours

the main measures to maintain and restore the normal operation of transportation pipeline and equipment include regular and temporary pipeline maintenance and repair

The operation of pig in the pipeline depends on the pressure difference formed before and after the pig, which is generally 0.3-0.5 kgf / cm. The pressure difference required by pigging ball is smaller than that of other pigging devices. After long-distance operation, the diameter of pigging ball becomes smaller, and the sealing performance and pigging effect will decline. The method of refilling water and pressurizing can be used to restore the diameter of pigging ball

a 50 mm thick pigging ball made of wear-resistant plastic can run about 2000 km. The pig has strong adaptability and can pass through the elbow with small curvature radius; With the help of the gravity of the ball, it can be in place when sending and receiving. The disadvantage of pigging ball is that it has poor effect in removing wax, rust and other solid substances in the pipe, high cost, and it is difficult to install test instruments on the ball

3. There is absolutely no radioactivity in the sewage of the radiology department of the hospital. If your hospital washes the waste water after the film to be many, informs me, free helps you to deal with

4. (1) Whether the reserved and embedded positions are consistent with the actual installation needs
(2) whether the location, size and elevation of equipment foundation meet the needs of pipeline laying
(3) whether the position, size and elevation of pipeline trench meet the needs of pipeline laying
(4) whether the building elevation datum point and setting out datum position are clear
(5) whether there is any contradiction between the laying position of water supply and drainage and fire fighting pipelines and the building, structural elevation, location and size
(6) whether the architectural design, such as the main structure, wall structure, door and window position, ceiling structure, interior and exterior decoration materials, is in conflict with the installation.

5. The main pipe in the water supply drawing is connected with the outdoor public main pipe. The data should be matched according to the depth of the local main pipe. If there is a gap between the elevation of the outdoor main pipe and the construction drawing, it should be constructed in the most convenient way, because the number of turns of the water pipe is too many, which is not concive to the water inflow, and there are many places that are easy to run, drip and leak after a long time, but it should be noted on the drawing, Otherwise, when other pipelines are constructed in the same position, once the elevation conflict is easy to cause disputes
when you enter the room, stick to the wall. The water inlet and drainage pipes should be close to each other, or they should be wrapped in a compartment surrounded by plywood. There is only one interface to the faucet and shower, and there is no need to reverse to the specific elevation, because the specific height should be calculated according to the height of the sink and shower, so after ordering the appliances, you can connect one section, Very convenient
the main pipe of the public drainage pipe in the drainage drawing is generally buried about 1000 ~ 1500 below the ground level. According to the area of the building water network, the water with large flow is generally deeper. At the same time, the economic benefits should be taken into account. It should not conflict with the public pipe network, and the laying depth should be indicated on the construction drawing. The reasons are the same as above. The location of the floor drain is generally 150 ~ 200 away from the extension of the inner wall, The approximate position is OK, because the drainage pipe of the wash basin is hose, even if it is not aligned, it can be extended in

water supply and drainage pipeline engineering is a pipe (canal) system engineering for transporting and distributing instrial water supply and drinking water, and collecting, transporting and discharging instrial wastewater, domestic sewage and rainwater
water supply and drainage pipeline engineering is an integral part of the water supply and drainage system, which plays an important role in the whole water supply and drainage system, including the pipe (canal) system itself and various structures on the pipe (canal) system (such as pump station, reservoir, pipe bridge, gate well, sewage inspection well, rainwater inlet, etc.). The project investment accounts for the majority of the total investment of water supply and drainage system.

6. Five blocks won't work. Now I'm also digging a pipe trench, one meter deep, 50 wide, eight blocks one meter, forty meters a well, and the well is calculated separately. But it's only 2000 meters. You have such a large amount of work. I think 7 yuan can do it. It can't be less than 7 yuan! My personal opinion is that one meter deep, some places should be higher than the plane, that is to say, some places may need to dig more than one meter deep, and one meter five is also possible. The most important thing is to look at the terrain.

7. There are generally two aspects in terms of drainage pipeline Public License facilities and maintenance economic indicators, which are generally implemented through the inspection of paigang town and the issuance of two schemes.

8. A comprehensive manpower and machinery (1 unit) operation team, with materials, practices and environment available, can lay about 350 to 450 meters of HDPE drainage pipes under municipal roads and 450 to 550 meters of HDPE drainage pipes in the construction area. The closed water test can only be carried out when the inspection well reaches the strength, Backfill also has to wait for closed water qualified, closed water backfill takes time; Under the municipal road, the concrete drainage pipe can be laid about 200m to 300m. In the field, the concrete drainage pipe can be laid about 250m to 350m. The closed water test must wait for the inspection well to reach the strength. The backfill must wait for the closed water to be qualified. The closed water backfill takes time.

9. For the drainage pipeline, it is generally necessary to do the water filling test and ball passing test. If the instrial pipeline is non gravity drainage, it is necessary to do the hydraulic test. If it is excluded as toxic liquid, it is also necessary to do the leakage test

drainage pipeline refers to the system composed of pipes and channels and their ancillary facilities for collecting and discharging sewage, wastewater and rainwater. Including the main pipe, branch pipe and the pipe leading to the treatment plant, whether it is built on the street or any other place, as long as it is a drainage pipe, it should be counted as a drainage pipe.
