Abstract

The invention discloses a temporary pipeline lower hoisting bracket and a trench excavating pipeline protection method. According to the hoisting bracket, a vertical rod and a suspender are arranged at the two ends of a cross rod, the vertical rod is welded to the cross rod, the upper end of the suspender is in threaded connection with a cross rod nut, and the lower end of the suspender is detachably connected with the bracket. An inclined strut is arranged between the cross rod and the vertical rod. The method comprises the steps that firstly, two hoisting brackets are arranged at the two longitudinal ends of the top of a foundation pit crown beam, and the distance between each vertical rod and the end of the foundation pit crown beam ranges from 4 m to 6 m; secondly, a crown beam top steel plate is fixed to the foundation pit crown beam through expansion bolts; thirdly, the vertical rods and the crown beam top steel plate are in full weld; fourthly, a lower plate is placed in each groove, a gas pipeline and a water supply pipeline are both located in a frame body of each bracket, each lower plate and corresponding two pieces of round steel are assembled, bracket nuts are screwed, and each bracket is connected with the corresponding suspender; fifthly, after a foundation pit is excavated, when a return pipe network trench is excavated to the position near each bracket, a trench construction side needs to screw suspender nuts on the brackets by a half circle again. The temporary pipeline lower hoisting bracket and the trench excavating pipeline protection method are used for temporary pipeline protection before foundation pit excavation in the municipal engineering.

Description

technical field [0001] The invention relates to a bracket used for underground pipeline hoisting and a pipeline protection method, in particular to a hoisting bracket under a temporary pipeline and a method for protecting a trenched pipeline. Background technique [0002] At present, before the excavation of the foundation pit of municipal engineering (including water supply pipelines, communication pipelines, rainwater pipelines, sewage pipelines, and power pipelines), it is necessary to temporarily relocate the existing gas pipelines and water supply pipelines to the foundation pit (that is, above the surface) ), the purpose of doing this is not to affect the normal use of gas and water supply. When the gas pipeline and water supply pipeline are moved back, the area for trench excavation is just below the existing temporarily relocated gas pipeline and water supply pipeline. Due to time constraints and small site, the gas pipeline and water supply pipeline cannot be reloc...
