Example Embodiment

[0039] Below in conjunction with the accompanying drawings of the description, the technical scheme of the present invention is further described:

[0040] like Figures 1 to 6 As shown in the figure, the construction method of the integral mobile formwork trolley for the cast-in-place pipe gallery of the present invention includes measuring and setting out, the construction of the bottom plate 1 and the lower chamfer 2, the installation of the formwork trolley 3, the placement of the inner mold, and the construction of the side wall 4 and the top plate 5. , demoulding and movement of the template trolley 3, including the following steps:

[0041] 1. Measure and stake out

[0042] The pipe gallery structure box is composed of the top plate 5, the bottom plate 1 and the side wall 4. When setting out, pay special attention to the alignment of the plane and vertical curve of the wall or plate with the road design alignment, and also pay attention to the cross slope setting of th...

Abstract

The invention discloses a construction method of integral type movement of a formwork trolley through a cast-in-place pipe gallery. The construction method includes the steps of measurement and lofting, bottom plate and lower chamfer construction, formwork trolley installation, internal mould emplacement, side wall and top plate construction, and demoulding and formwork trolley movement. Accordingto the construction method, the construction progress is effectively improved, and the construction cost is lowered; except for first installation and final removal completing of the whole section ofpipe gallery construction, the formwork trolley is not required to be installed and disassembled, a great deal of labor and machinery is reduced, waste of intermediate materials is reduced, the formwork trolley can be used continuously only by proper maintenance and repair, good economic benefits are achieved; pipe gallery pouring seams are reduced, anti-seepage, anti-seismic and anti-freezing properties are good after pouring, late operation and maintenance costs are effectively reduced, and meanwhile, attractiveness of a pipe gallery is improved; and compared with a full framing method, waste of a fastener, a support and other resources can be effectively reduced, pollution is reduced, and social benefits are good.

Description

technical field [0001] The invention belongs to the technical field of construction of a cast-in-place pipe gallery, and in particular relates to a construction method of a cast-in-place pipe gallery with an integral mobile formwork trolley. Background technique [0002] The main function of the comprehensive pipe gallery is to bring together gas pipelines, water supply pipelines, drainage pipelines and communication cables. It has the advantages of one-time excavation, centralized construction, and avoiding repeated excavation of the same road section. It has become an important part of urban infrastructure development. In recent years, it has been more and more widely used in my country's urban municipal construction. Usually, the comprehensive pipe gallery is poured on the construction site, and the method of segmented and layered construction is generally used in the cast-in-place comprehensive pipe gallery. The bottom plate of the corridor, and then manually set up temp...
