Construction system and method of pipe gallery with integral prefabricated pipe joint and internal partition

Abstract

The invention relates to a construction system and method of a pipe gallery with an integral prefabricated pipe joint and internal partition. The pipe gallery includes the integral prefabricated pipejoint and internal partition; grouting holes are formed in the side wall of the pipe joint; the construction system includes an unearthed system, an antifriction grouting pipe system and a jacking system; the unearthed system includes a spiral unearthing machine, a supporting pump and a pump pipe; the supporting pump pipe is connected with the spiral unearthing machine; one end of the pump pipe isconnected with the supporting pump, and the other end of the pump pipe is extended into a residue pool; a high pressure water injecting ring is arranged between the pump pipe and the supporting pump;the antifriction grouting pipe system includes grouting pipes and grouting valves; the grouting valves and the grouting holes are arranged correspondingly; the grouting valves comprise transverse pipe sections and longitudinal pipe sections; ports of the longitudinal pipe sections are connected with the grouting holes; the number of the grouting pipes is two less than the number of the grouting valves, and the grouting pipes are correspondingly connected among the adjacent grouting valves; ports of one ends of the two grouting valves at the very bottom are left as slurry injection ports; andembedded steel pipes are arranged on the internal partition. The construction system and method of the pipe gallery with the integral prefabricated pipe joint and internal partition solve the technical problem that the integrity of the pipe joint and the internal partition is poor in the construction of a traditional pipe-jacking pipe gallery, and the field assembly or the cast-in-place construction is not easy.

Description

technical field [0001] The invention belongs to the technical field of urban underground comprehensive pipe gallery engineering, and in particular relates to a construction system and a construction method of a pipe gallery in which pipe joints and inner partitions are integrally prefabricated. Background technique [0002] The underground comprehensive utility corridor is an important infrastructure and lifeline to ensure the operation of the city. In recent years, my country is vigorously promoting the construction of urban comprehensive pipe corridors. During the construction of pipe corridors, important obstacles such as highways, railways, municipal roads and rivers are often encountered. Traditional construction methods are not suitable for these obstacles. The impact is too great, and it can no longer meet the construction requirements of this type of pipe gallery. The rectangular pipe jacking method is widely used in the construction of pipe gallery because it does n...
