Large-section multi-chamber cast-in-place comprehensive pipe gallery and its construction method

Abstract

The invention relates to a large-section multi-chamber cast-in-place integrated utility tunnel, comprising a formwork system, a top transfer platform, a protection platform and a steel bar binding support frame; the support die system comprises a foundation pit, a side support, a side template, a utility tunnel, a first fixed plate, an L-shaped support frame, a support groove, a second fixed plate, an inner template, a fixing bolt and a top support; the top transfer platform comprises a winch, a transfer platform, a prefabricated first slide rail, a prefabricated second slide rail, a sliding wheel, a groove, a left side gasoline engine, a right side gasoline engine and a slide rail connecting plate; the protection platform comprises an upper-layer protective net, a platform, a lower-layerprotective net, a protective net clamp plate, a sliding wheel, a prefabricated third slide rail and fixing nails. The large-section multi-chamber cast-in-place integrated utility tunnel has the beneficial effects that the support groove is formed in the side template, the first fixed plate is arranged on the side plate, the support groove is used for placing the top end of the side support, the first fixed plate is used for embedding and fixing the L-shaped support frame, and the side template can be effectively prevented from moving sideways.

Description

technical field [0001] The invention relates to the field of comprehensive pipe gallery, in particular to a large-section multi-chamber cast-in-place comprehensive pipe gallery and a construction method thereof. Background technique [0002] The comprehensive pipe gallery 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 The monitoring system, which implements unified planning, unified design, unified construction and management, is an important infrastructure and "lifeline" to ensure the operation of the city. [0003] At present, there is still room for improvement in the construction of the pipe gallery, including the formwork of the pipe gallery, construction safety protection, fast binding of steel bars and material transportation.

AI Technical Summary

Problems solved by technology

The operation space of the foundation pit is small, and it is impossible to accumulate a large amount of materials. If there is too much material accumulation, the normal operation of the construction personnel will be affected; the width inside the foundation pit is small. The construction efficiency is low, because the pull bolts are generally long and cannot be operated normally inside the foundation pit. In addition, when the top panel of the pipe gallery is constructed, it is necessary to set up supports on the formwork at the bottom to prevent the concrete from falling, while the traditional full-wall support takes up space Larger and lower construction efficiency; during the construction of the pipe gallery, things often fall into the foundation pit. On the one hand, the dropped things occupy the space of the foundation pit; security threat
