Automatic buried pipe laying device and pipe burying method

Abstract

The invention relates to an automatic buried pipe laying device and a pipe burying method. On one hand, the automatic buried pipe laying device can fix a water supply pipe and a water return pipe of aU-shaped buried pipe through arc-shaped clamping plates in two clamping devices, enables the water supply pipe and the water return pipe to be in a parallel state, and facilitates installation of a pipe clip or a pipe clamp on the buried pipe between the two clamping devices; and on the other hand, after the pipe clip or the pipe clamp is installed, the two clamping devices can alternately do pulling and pipe laying actions through clamping mechanisms in the clamping devices, and the buried pipes are continuously conveyed into a drilled well. The relatively flexible clamping mechanism is formed in each clamping device through a sliding column, a connecting rod, an L-shaped clamping rod and other components, and the clamping mechanisms ensure that the buried pipe cannot be damaged while the two branch pipes of the buried pipe are clamped. Therefore, the automatic pipe laying device can replace manual work to conduct automatic pipe laying operation, the efficiency is higher, the pipe laying process is more stable, the construction period is shortened, and the automatic pipe laying device is suitable for comprehensive popularization.

Description

technical field [0001] The invention relates to the technical field of pipe-laying equipment, in particular to an automatic pipe-laying device and a pipe-laying method for buried pipes. Background technique [0002] At present, ground source heat pumps use a large amount of low-temperature heat energy stored in underground soil, rocks, groundwater or other media to provide heating, air conditioning and hot water for building spaces. In summer, the waste heat removed by the air conditioner is transported underground, and in winter, the heat in the soil is extracted to provide heating for the air conditioner. Ground source heat pump is by far the most comfortable, efficient, environmentally friendly and energy-saving technology. It is the latest and highest-grade air-conditioning and heating system in the world and has been widely used. The downpipe is one of the keys to the construction of the buried pipe ground source heat pump system. Because the depth of the downpipe dete...

Problems solved by technology

[0003] Most of the existing buried pipes use manpower to apply force to the U-shaped buried pipe to implant the buried pipe into the drilling well. Since the water in the well will generate a large buoyancy force on the U-shaped buried pipe, the force applied by manpower is used. The method will consume a lot of physical strength of the construction workers, and the efficiency is not high; in addition, in order to avoid the heat backflow caused by the too close distance between the water supply pipe and the return pipe of the U-shaped underground pipe (the temperature difference between the water supply pipe and the return pipe is large, and they are close together It will generate heat backflow, also called "thermal short circuit"). At present, most of the market uses supports such as pipe clamps or pipe clamps to support the water supply pipe and return pipe to keep a certain distance. Since the buried pipe made of PE material has certain elasticity, Therefore, when installing pipe clips or pipe clips, it is necessary to manually control the water inlet pipe and the return pipe to be in a parallel state, and then install the pipe clips or pipe clips on the water inlet pipe and the return pipe. This installation method requires multiple people to operate, which is inconvenient and inefficient , so it is necessary to design an automatic underground pipe lowering device to assist in lowering the pipe and installing pipe clamps or clamps
