Background
The heat supply pipeline has two modes of underground laying and overground laying. The underground laying does not affect the urban traffic and the urban appearance, and is a laying mode widely adopted by urban heat supply. The ground laying is also called overhead laying, has low manufacturing cost and convenient maintenance, and is mainly used in areas with special geological structures, such as industrial areas, suburbs, high underground water level, permafrost areas, collapsible soil areas and the like, and areas crossing railways, roads, rivers and the like. Special supports are mostly arranged. According to different heights of the supports, the supports are divided into a high support, a middle support, a low support and ground laying. At present, cities pay great attention to the economy of developing river landscape, so that the heat pipe network does not adopt an overground laying method for crossing river sections, but adopts a laying method for crossing river bottoms. The method is that heat supply pipelines with the length of 6 meters are pushed into a top pipe section by section, and each section of heat supply pipeline is fixedly connected end to end through a hoop. In the construction, the resistance of the propulsion heating pipe is large, and the working efficiency is directly influenced.
To solve the above problem, patent document No. CN201954105U discloses a pulley bracket for laying a pipeline of a heat supply network by using trenchless technology, wherein bracket legs and rollers are symmetrically arranged on the outer circle of a hoop, so that the pushing work of the heat supply pipe can be conveniently completed, however, the pulley bracket cannot retract the rollers after pushing, and further when the heat supply pipe is subjected to external vibration in the top pipe, the heat supply pipe moves along the top pipe, so that the fixation between the heat supply pipe and the top pipe is very loose.
