Comprehensive Arrangement System and Construction Method of Temporary Pipelines on Edge of Deep Foundation Pit

Abstract

The invention provides a workside temporary pipeline comprehensive distribution system of a deep foundation pit and a construction method of the system. The construction method comprises the followingsteps: pouring slope protection pile crown beam and an annular hardening pavement, mounting placement overhanging angle steel, mounting inner side and outer side tool guardrails, constructing a workside water retention and drainage system of the foundation pit, observing foundation pit data, mounting an assembled retention wall, mounting channel steel brackets, mounting a downcast pipeline bridgeframe, mounting a feed-water pipeline bridge frame, mounting a cable bridge frame, mounting downcast pipelines, a production water pipeline and a fire-fighting main pipeline, mounting a spray branchpipe, mounting a wiring slot case, distributing cables, mounting a bracket encapsulated slot rain-proof top cover, mounting a downpipe of the rain-proof top cover, mounting a fire-fighting case, and dismounting a temporary pipeline. The workside temporary pipeline comprehensive distribution system of the deep foundation pit can effectively ensure safety protection of workside construction of the deep foundation pit; the difficulty that the traditional buried lay cannot be adopted for the temporary construction pipeline due to a narrow field is solved; and the reliability of the safety protection is improved due to the deeper foundation pit.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a comprehensive arrangement system and construction method for temporary pipelines bordering deep foundation pits, and is particularly suitable for the construction of the comprehensive temporary pipelines arrangement system bordering deep foundation pits. Background technique [0002] In recent years, due to the higher and higher functional requirements of the building itself, the installation design of the building has become more and more complicated, and more and more related disciplines are involved, and it is difficult to be thorough and meticulous in the design process of each discipline Due to the consideration of the pipeline arrangement, there are problems such as disorderly arrangement and unreasonable use of space, which not only affect the architectural decoration effect, but even affect the use and maintenance. The application of pipeline comprehensive balance techn...

[0002] In recent years, due to the higher and higher functional requirements of the building itself, the installation design of the building has become more and more complicated, and more and more related disciplines are involved, and it is difficult to be thorough and meticulous in the design process of each discipline Due to the consideration of the pipeline arrangement, there are problems such as disorderly arrangement and unreasonable use of space, which not only affect the architectural decoration effect, but even affect the use and maintenance

The application of pipeline comprehensive balance technology has better solved the rational use of building space and enhanced the rationality of pipeline layout. However, compared with large-scale projects with complex design and large pipeline volume, due to its functional requirements, the space of each floor may be separated. They are all different. The public space is divided into blocks and slices, and the distribution is crossed. It is difficult to achieve a systematic and in-depth pipeline balance. Therefore, it is particularly important to do a good job of pipeline balance before construction.

[0003] Temporary water and electricity pipelines are buried in the traditional construction site, and a large number of mechanical shifts are required for trench digging and landfill construction in the early stage, and the soil needs to be re-dug and filled during maintenance. Taiban, in many cases, the recycling rate of cables and water pipes is low or has no recycling value at all
