Waterproof test interface structure and prefabricated joint pressure waterproof test test system

Abstract

The invention provides a waterproof test interface structure and an assembled joint pressure waterproof test system, including an outer mold, an inner mold and a water inlet pipe; the outer mold is a rigid component and has a plurality of splicing bodies, and the plurality of splicing bodies are sequentially spliced ​​to form a cylinder The top of each spliced ​​body is folded outward to form the outer mold brim; the inner mold is a flexible member, the inner mold has an inner mold middle barrel inserted in the outer mold middle barrel, and the top of the inner mold middle barrel is The inner mold brim is folded outward to form a ring-shaped inner mold brim, the inner mold brim is attached to the upper surface of the outer mold brim, the side wall of the inner mold middle cylinder is provided with a water inlet that communicates with its own inner cavity, and the bottom end of the inner mold middle cylinder is closed. , a water injection port is formed at the top; the water inlet pipe runs through the spliced ​​body and is connected to the water inlet. The waterproof test interface structure and the prefabricated joint pressure waterproof test system provided by the invention ensure good sealing at the butting position of the joint test piece, and will not affect the deformation of the joint test piece, so as to ensure the accuracy and reliability of the test data .

Description

technical field [0001] The invention belongs to the technical field of building simulation test equipment, and particularly relates to a waterproof test interface structure and an assembled joint pressure waterproof test system. Background technique [0002] Prefabricated buildings refer to the transfer of a large number of on-site operations in the traditional construction method to the factory, the construction components and accessories are processed in the factory, transported to the construction site, and assembled and installed on site through reliable connections. , its construction speed is fast, the production cost is low, and it meets the requirements of green building. [0003] Prefabricated underground structures are an important branch of prefabricated buildings, which are widely used in subway stations and other occasions, and their structural stability and waterproof performance are critical to the construction of underground engineering. During the waterproo...

Problems solved by technology

During the waterproof test, injecting water into the seam between adjacent joint specimens is an important operation link. However, according to the existing test conditions, the sealing of the water injection interface structure and the docking position of the joint specimens is poor, and the It will affect the deformation of the joint test piece, which is not conducive to obtaining accurate test data related to the stability of the joint under water and load conditions
