Concrete compacting technology of urban underground shield tunneling machine

Abstract

The invention relates to a concrete compacting technology of an urban underground shield tunneling machine. The concrete compacting technology is characterized in that the simple shield tunneling machine, a slip form sleeve pouring system and a concrete pump station are involved, the working environment is dug by the simple shield tunneling machine in the front, a concrete pumping pipe is used forpumping concrete in a concrete pump truck into a concrete pouring pipe, the concrete pouring pipe is used for pouring concrete into the portion between a cast-in-place concrete inner wall sleeve anda cast-in-place concrete outer wall sleeve, fast hardening concrete is adopted to reach the working strength fast, concrete partition plates are used for partitioning the concrete, in the pouring process, vibrating machines located on the cast-in-place concrete inner wall sleeve and the cast-in-place concrete outer wall sleeve do vibrating work to compact the concrete, and when pouring is completed, a main driving device of the shield tunneling machine drags the sleeve pouring system to move forward and conduct pouring work. The concrete compacting technology has the advantages of being high in construction speed and low in influence on the environment, pipe piece transportation is avoided, transportation cost is reduced, one-off pipeline forming intensity is high, and the advance speed ishigh.

Description

technical field [0001] The invention relates to a tunnel excavation technology, which belongs to the field of municipal construction. Background technique [0002] The comprehensive pipeline corridor (called "common ditch" in Japan and "common pipeline" in Taiwan) is the comprehensive corridor of underground urban pipelines. That is to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports, hoisting ports and monitoring systems, implementing unified planning, unified design, Unified construction and management is an important infrastructure and "lifeline" to ensure the operation of the city. [0003] The development of my country's urbanization density is distorted. According to the traditional planning concept, it is difficult to meet the current development requirements. The municipal pipelines that match the residence, such as reclai...

Problems solved by technology

From the point of view of the underground comprehensive pipe gallery projects that have been built in China, most of them are based on the open-cut and cast-in-place method. This construction method is relatively low in cost, but it has a greater impact on the environment.
