Fire trench pipe fittings manufacturers talk about the preparations for PE pipe trench construction

2022/09/30

PE pipe is a common professional pipe in today's industrial production. It is generally effective for large-scale projects. Therefore, in order to better ensure its application quality, it is necessary to clarify the size of avoidable parts before construction, and carry out groove engineering to make the pipe easy to use. layout. The following fire trench pipe fittings manufacturers talk about the preparations for PE pipe trench construction.

(1) Before excavation, first understand the situation of the underground pipelines along the roads along the pipeline line on site to prevent damage during construction.

(2) The data of the bottom width of the PE pipeline trench excavation is clear, and appropriate adjustments are made according to the site conditions to ensure that the operators work at the bottom of the trench.

(3) The relative slope coefficient can be selected according to the construction site environment, groove depth, groundwater level, soil condition and other factors, and the excavation slope can be adjusted appropriately to stabilize the excavation slope. When the fire trench pipe fitting manufacturer believes that the soft soil trench slope is not suitable for setting static load or dynamic load, calculate the bearing capacity of the soil and the stability of the slope.

(4) The distance between PE official side piles and the slope area shall not be less than 500 mm, and the pile height shall not be less than 1500 mm to ensure safe construction.

(5) For earthwork excavated by trenches, the earthwork that can be used is piled up on one side, and the earthwork that cannot be used is immediately transported to a specific yard for accumulation.

(6) The surface of the bottom of the ditch should be straight and flat, and there should be no gravel, hard blocks and other protrusions on the surface. Pipe trenching should not shake the original soil at the bottom of the trench. The machine is excavated, and in the absence of groundwater, the home floor needs to be buried 200mm in advance, and some need to manually clean the floor before the pipe is installed.

(7) The PE pipe should be laid on the original ground foundation, partially excavated, re-filled and compressed. When there is no groundwater on the ground, and the depth is within 150 mm, it can be filled and compressed with the original soil, and its density is lower than that of the original natural soil. If the depth exceeds 150mm, it can be compacted with sand or sand with a density of less than 90%.

(8) If there are abandoned buildings, pumice, wood, waste and other dirt at the bottom of the ditch, after removing it, spread red soil or sand with a thickness of more than 150 mm and flatten it. The manufacturer of fire trench pipe fittings recommends laying a laterite or sand cushion with a thickness of more than 150 mm on the rock foundation.

(9) Drainage measures should be taken when digging trenches to prevent getting wet by water.

In order to ensure the application quality and safety of PE pipes in the middle and late stages, when carrying out the trench engineering, the fire trench pipe fittings manufacturer believes that it is necessary to carry out detailed solutions in accordance with the stated solution regulations, and take perfect protection measures after the end of the project to prevent trench deformation. or destruction, the project can be completed.

Fire groove pipe fittings manufacturers share the five major advantages of groove fixtures

1. Only the handles for cutting machines, excavators and button bolts are needed to help the construction safety site. The construction organization is convenient and safe.

2. The stainless steel grooved pipe connection is easy to operate, saves time and effort, and has good economic benefits.

3. The operation is simple and does not require special professional skills. The bolts on the clamp can be tightened with a wrench to fix the seal, and ordinary workers can operate it through simple training.

4. The original characteristics of the pipeline are not affected. The grooves are squeezed with rollers only on the outer surface of the connected pipes, without damaging the inner wall structure of the pipes.

5. The system has good stability, convenient maintenance, simple connection of grooved pipe fittings, and reduced working space, which provides many convenient conditions for future maintenance. If the pipe needs to be repaired and replaced, simply loosen the two clamps and the pipe segment can be freely replaced, rotated and modified. There is no need to destroy surrounding walls, reducing repair time and maintenance costs.
