Problems solved by technology

[0002] With the continuous progress of society and the continuous development of science and technology, underground pipe galleries are widely used in modern cities. Cast-in-place concrete pipe galleries often cannot be constructed normally due to rainy days, and the construction period is very long. Precast concrete pipe galleries are constructed in pipe galleries. However, the disadvantage of prefabricated concrete pipe gallery is that its interface is prone to dislocation and deformation due to uneven foundation settlement, which causes leakage and fracture at the interface.

Abstract

The invention discloses a concrete pipe rack precasting connecting method. The connecting method comprises the following steps that before a concrete pipe rack is precasted, a positioning plate is pre-buried on the section of the concrete pipe rack, accurate positioning of pre-buried steel pipes is guaranteed, and the positioning plate is fixed with a positioning plate base; the pre-buried steel pipes are mounted through positioning holes on the positioning plate, spacing between the pre-buried steel pipes are determined according to calculating of stressing conditions, and the pre-buried steel pipes penetrate through the positioning plate through the positioning holes; and pipe rack precasting is conducted after the positioning plate and the pre-buried steel pipes are mounted, after pipe rack precasting is finished, the pipe rack is conveyed to a construction site to be mounted, during pouring, the part, near a foundation, of a connector of the pipe rack is firstly poured, and then the rest parts of the pipe rack are poured through a stereotyped steel mould. The concrete pipe rack precasting connecting method has the beneficial effects that the problems that due to the fact such as uneven settlement of the foundation, up and down dislocation and deformation of the connector of the precast concrete pipe rack are prone to occur, and the phenomena of connector leakage and breakage are caused are effectively solved, and the connecting quality of the connector of the precast concrete pipe rack is effectively controlled.

Description

Technical field [0001] The invention discloses a connection method, in particular a connection method for a precast concrete pipe gallery, and belongs to the technical field of construction methods. Background technique [0002] With the continuous progress of society and the continuous development of science and technology, underground pipe corridors are widely used in modern cities. Cast-in-place concrete pipe corridors are often unable to be constructed normally due to rain, and the construction period is very long. Precast concrete pipe corridors are constructed in the pipe corridors. It has been gradually promoted and applied, but the disadvantage of the precast concrete pipe gallery is that its joints are prone to dislocation and deformation due to uneven foundation settlement and other reasons, causing leakage and breaking at the joints. Therefore, a connection method for precast concrete pipe gallery is proposed to solve the above problems. Summary of the invention [000...
