Waterproof test interface structure and assembly type joint pressure waterproof test system

Abstract

The invention provides a waterproof test interface structure and an assembly type joint pressure waterproof test system. The waterproof test interface structure comprises an outer mold, an inner mold and a water inlet pipe; the outer mold is a rigid component and is provided with a plurality of splicing bodies; the plurality of splicing bodies are spliced in sequence to form a cylindrical outer mold middle cylinder; the top end of each splicing body is overturned outwards to form an outer mold brim; the inner mold is a flexible component; the inner mold is provided with an inner mold middle barrel inserted into the outer mold middle barrel; the top end of the inner mold middle barrel is overturned outwards to form an annular inner mold brim; the inner mold brim is attached to the upper surface of the outer mold brim; a water inlet communicated with an inner cavity of the inner mold middle barrel is formed in the side wall of the inner mold middle barrel; the bottom end of the inner mold middle barrel is closed; a water injection opening is formed in the top end of the inner mold middle barrel; and the water inlet pipe penetrates through the splicing bodies and is abutted with the water inlet. According to the waterproof test interface structure and the assembly type joint pressure waterproof test system which are provided by the invention, good sealing performance of a butt joint position with a joint test piece is ensured, deformation of the joint test piece cannot be influenced, and accuracy and reliability of test data are ensured.

Description

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

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
