Novel assembling type precast concrete urban comprehensive pipe gallery and construction method thereof

Abstract

The invention discloses a novel assembling type precast concrete urban comprehensive pipe gallery and a construction method thereof. The novel assembling type precast concrete urban comprehensive pipe gallery comprises a plurality of inverted u-shaped cover plates and a plurality of substrate plates, wherein each inverted u-shaped cover plate comprises a cross plate, a left vertical plate and a right vertical plate; each substrate plate comprises a bottom plate, a left convex plate and a right convex plate; the middle position of each left convex plate and each right convex plate is provided with troughs; each left vertical plate and each right vertical plate are respectively installed in each left convex plate and each right convex plate; the middle position of each bottom plate is provided with a central drain. The construction method of the novel assembling type precast concrete urban comprehensive pipe gallery comprises the following steps: preparing prefabticated members; excavating and timbering a foundation pit; laying a cushion ply; connecting the inverted u-shaped cover plates with the substrate plates; connecting the inverted u-shaped cover plates, and connecting the substrate plates; tensioning, smearing gaps, backfilling and carrying out form stripping. The novel assembling type precast concrete urban comprehensive pipe gallery has the advantages of convenience in transportation, construction and maintenance, simpleness in operation and high construction efficiency, and the structural integrity and stability of a gallery body can be improved, and the water resistance and water discharging performances of the pipe gallery can be improved.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to a novel assembled prefabricated concrete urban comprehensive pipe gallery and a construction method thereof. Background technique [0002] The comprehensive pipe gallery intensively accommodates the pipelines in the comprehensive pipe gallery, which not only beautifies the environment, but also avoids the trouble of repeated excavation of the road surface due to burying or repairing pipelines; because the pipeline does not touch the soil and groundwater, it avoids soil damage. The corrosion of the pipeline prolongs the service life; the construction of the comprehensive pipe gallery also reserves valuable underground space for planning and development. At present, there have been a variety of prefabricated pipe corridors, among which integral prefabrication and prefabricated prefabrication are commonly used. [0003] Because the comprehensive pipe gallery is relati...

AI Technical Summary

Problems solved by technology

[0003] Because the comprehensive pipe gallery is relatively large in size, the integral prefabricated pipe gallery is often very heavy, which brings a lot of inconvenience to factory prefabrication, transportation, and on-site hoisting; there is also a prefabricated integrated pipe gallery method that supports, side panels, and roofs are installed in the factory. Separate prefabrication and assembly on site; however, although this method overcomes the inconvenience caused by the weight of the integral prefabricated comprehensive pipe gallery, the structure is unstable after the assembly of the side panels and the top panel, the force transmission effect is not good, and there are connections There are many places, which increases the chance of water penetration and other defects
