Example Embodiment
[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments. The description of the embodiments is only used for a better understanding of the present invention. It should be emphasized that for those of ordinary skill in the art, the Under the premise, several improvements and adjustments can be made to the present invention, especially in terms of the size of the flexible preform and the materials used. These improvements and adjustments are also protected by the claims of the present invention.
[0040] Such as Figure 1-5 As shown, according to the design requirements, a certain length of flexible prefabricated parts 10 containing deformation seams are prefabricated in a prefabricated factory. The structural form requirements of the flexible preform 10 are as follows:
[0041] The cross-sectional dimensions such as the height and width of the flexible preform are the same as those of the rigid structure section of th...

The invention discloses a flexible prefabricated member and a method for constructing a pipe gallery by using the flexible prefabricated member. The flexible prefabricated member comprises left and right concrete pipe gallery sections, wherein a deformation joint is formed between the left and right concrete pipe gallery sections, and a form of a buried steel edge rubber waterstop is adopted in the deformation joint and the deformation joint is filled with polyethylene foam plates and sealant; and reinforcing bar joints are reserved in the end faces of the left and right concrete pipe gallerysections, and a circle of water-stop steel plates are separately embedded in the end faces of the left and right concrete pipe gallery sections. The method for constructing the pipe gallery by using the flexible prefabricated member comprises the steps that the prefabricated flexible prefabricated member is transported to a construction site; the reinforcing bar joints reserved in the two ends ofthe flexible prefabricated member are in butt-jointing with horizontal reinforcing bars of rigid cast-in-place sections; and other reinforcing bars in a local area of the connecting section are encrypted, a formwork is supported, and uniformly casting is carried out to enable the flexible prefabricated member and the rigid cast-in-place section to form a whole. According to the flexible prefabricated member and the method for constructing the pipe gallery by using the flexible prefabricated member, the forming quality of the deformation joint is improved through fine prefabrication, and the hidden danger of leakage is reduced; rigid splicing is more mature than flexible splicing; the construction is simple, and the construction period is effectively shortened; and material consumption is reduced.
Description
technical field [0001] The invention belongs to the field of waterproof technology and construction technology of urban underground comprehensive pipe gallery, in particular to a flexible prefabricated part and a method for constructing a pipe gallery using the flexible prefabricated part, and is especially suitable for cast-in-place pipe gallery and prefabricated laminated plate pipe gallery Construction treatment at deformation joints. Background technique [0002] The urban underground comprehensive pipe gallery refers to an infrastructure building built underground in the city, mainly used to accommodate municipal pipelines such as water supply and drainage pipelines, heat pipelines, gas pipelines, power cables, and communication cables. Compared with the traditional direct burial of pipelines, the urban underground comprehensive pipeline gallery has many advantages, including: unified management of all pipelines, convenient maintenance; solving the problems of "road zip...
