Problems solved by technology
Wooden formwork is not waterproof, prone to mildew and rot, low reuse rate, consumes wood resources, and is not conducive to the protection of ecological environment and forest resources; steel formwork is too heavy, requires the assistance of mechanical equipment for construction, and is easy to rust. Medium is easy to bond with concrete, and it is difficult to demould; plastic formwork has poor rigidity, is easy to deform, and is expensive

Embodiment Construction
[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0036] refer to figure 1 , a continuous construction method for aluminum alloy formwork used in a comprehensive pipe gallery. The main structure of the comprehensive pipe gallery is divided into two layers of construction, that is, the construction of the bottom plate and the guide wall 2, and the construction of the wall and the roof 6. In the horizontal direction, the expansion joints are segmented according to the structural design, and the horizontal construction joints are set in the vertical direction. Waterproof steel plates 4 and rubber waterstops are installed at the positions of the construction joints. Top plate 6, including 2 sets of combined aluminum alloy formwork for the first pouring, 1 set of aluminum alloy formwork for the second pouring, and 3 sets of early demolition supports to achieve continuous cycle operation. The specific co...

The invention relates to the construction of an underground comprehensive utility gallery, in particular to a continuous construction method of an aluminum alloy formwork used for the comprehensive utility gallery. Including the following steps: A, the first pouring construction of the first section of the comprehensive pipe gallery; B, the second pouring construction of the first section of the comprehensive pipe gallery and the first pouring construction of the second section of the comprehensive pipe gallery are carried out simultaneously; C, the first Formwork demolition of the section comprehensive pipe gallery; D, the second pouring construction of the second section of the comprehensive pipe gallery; F, the first pouring construction of the third section of the comprehensive pipe gallery. The invention realizes continuous cycle operation, quick turnaround construction, accelerated construction speed, shortened construction period, saves construction materials, and the construction environment is safer, greener and more environmentally friendly. At the same time, the concrete structure formed by the invention has smooth and smooth surface quality, meets the requirements of facing and fair-faced concrete, and does not need secondary plastering, saving construction costs.
Description
technical field [0001] The invention relates to the construction of an underground comprehensive utility gallery, in particular to a continuous construction method of an aluminum alloy formwork used for the comprehensive utility gallery. Background technique [0002] With the rapid development of urban networked municipal pipe network system, repeated excavation of roads due to pipeline expansion, renewal, maintenance, etc. is very common. As a new model that effectively solves the contradictions of urban infrastructure construction, comprehensive pipe corridors have gradually been recognized and promoted. . [0003] At present, the formwork project of the comprehensive pipe gallery mainly consists of three traditional formworks, namely wood formwork, steel formwork and plastic formwork. Wooden formwork is not waterproof, prone to mildew and rot, low reuse rate, consumes wood resources, and is not conducive to the protection of ecological environment and forest resources; s...
