Decoration and installation What is called direct burial and pipe trench

Direct burial is to bury the pipeline directly into the soil after anti-corrosion, the pipe ditch is to use bricks or concrete to pour a square trench, the bottom of the concrete, the top cover of the prefabricated plate, there is a pass, semi-pass ditch, etc., when installing the pipeline to do support, the pipe ditch is easy to maintain, the cost is high, and multiple pipelines can be installed.

Direct burial] When decorating, one of the laying methods of the engineering pipeline can be understood as direct burial, that is, direct trenching, laying and backfilling. Direct burial laying should pay attention to the depth of soil covering, horizontal and vertical clear distance between pipelines must meet the requirements of the corresponding specifications.

Pipe ditch] The comprehensive pipe ditch will be equipped with special maintenance ports, hoisting ports, drainage facilities, fire protection facilities, ventilation facilities and detection and monitoring systems to facilitate the operation and management of pipe trenches. Compared with the traditional pipeline single burial method, the integrated pipe trench has obvious advantages:

One-time comprehensive investment to avoid repeated excavation; intensive use of space resources; Good disaster prevention performance; Unified management, convenient maintenance, reduce management costs.

Just take it literally, direct burial is direct burial, and pipe ditch is pipe ditch, which is generally bricked or poured.

Direct burial is a plastic sleeve steel insulation pipe (high-density polyethylene direct buried insulation pipe) and a steel jacket steel insulation pipe (high temperature steam insulation pipe).

Pipe trench, the groove used for laying pipelines is called pipe trench. Generally, there are three types: a passable pipe ditch b impassable pipe ditch c semi-passable pipe ditch.

Summary. Hello, for you to find out that the direct burial laying belongs to the buried pipeline, and the pipe trench laying belongs to the laying in the trench, the difference is that the former is buried, and the latter is laid in the trench. Pro-<>

Who knows what is the difference between pipe trench laying and direct burial laying?

This question is up to me, it takes a little time to query the information, please be patient, dear! <>

Hello, for you to find out that the direct buried beam liquid is a buried pipeline, and the pipe trench laying is a laying in the trench, the difference is that the former is buried in the slag and the latter is laid in the trench. Pro-<>

Hello, for you to find out the difference between the pipe trench laying section and the direct burial laying: the direct burial laying is a buried pipeline, and the pipe trench laying is a laying in the trench, the difference is that the former is buried, and the latter is laid in the ditch. Dear [open the grip and quietly lose the heart].

Dear, what else do you need to consult? ☺️

Oh. Dear, if you don't have any other questions, can you give a like and follow? If you still have any questions that need to be consulted, you can click on my page to consult me! Thank you, your support is the motivation for my blind work! [than the heart] [than the heart] [than the heart].

Direct burial is to dig up the soil, put the pipes in it, and then fill it with soil.

The pipe trench is to first build a structure similar to a culvert pipe at the position of the underground pipeline direction, and then put the pipeline in the pipe trench.

The cost of direct burial is low, the construction is simple, and the cycle is short. However, it is difficult to maintain the pipeline, and the maintenance has an impact on the surrounding environment. The burial of different pipelines requires multiple excavations.

The advantage of the trench is that the pipeline is simple to maintain, and different pipelines can be placed in the trench. However, the cost of the pipe trench is high and the construction period is long. And not all pipelines can be included.
