Embodiment 1

[0028] Embodiment 1: A kind of waterproof performance simulation test device for paste waterproof material, see Figure 1 to Figure 4 , including the right fixed test block 2, the left fixed test block 3, the water pressure gauge 4 and the paste waterproof material 1; wherein, the left and right fixed test blocks 2 and 3 are concrete main structures, corresponding to a thickness of 200mm The flanks 5 and 7 are integrally poured together, and the flanks on three sides are all fixed to the hardened ground 6 with bolts. Inside the left and right fixed test blocks 3 and 2, there are 200mm*200mm*200mm cavity 9 and water injection chamber 8 correspondingly. 2. After applying water-stop material in the water injection chamber 8, seal it with a movable cover plate. In addition, in the middle of the left and right fixed test blocks 2 and 3, a 50 mm wide deformation joint is formed through the cavity to communicate with the outside world, and the paste-like water-stop material 1 is fil...

Embodiment 2

[0029] Embodiment 2: The waterproof performance simulation test device for paste water-stop material is implemented by utilizing the waterproof performance simulation test device described in Example 1, including the following steps:

[0030] (1) Set the left and right fixed test blocks 2 and 3 on the hardened ground 6 with a distance of 50 mm, and fix the three side wings 5 ​​and 7 corresponding to the left and right fixed test blocks 2 and 3 to the hardened ground 6 with bolts ;

[0031] (2) From the movable cover plate on the right side of the right fixed test block 2, extend into the deformation joint, and apply the paste water-stop material 1;

[0032] (3) Fix the sealing cover on the right side of the right fixed test block 2 with bolts, and seal all joints;

[0033] (4) Fill water into the water injection chamber 8 from the water injection pipe 10 on the top of the right fixed test block 2, observe the water meter value reaching the full water state, and record the val...

Abstract

The invention discloses a waterproof performance simulation test device and a waterproof performance simulation test method for a pasty water stop material, and aims to solve a problem that an effective technical means for pre-evaluation of application effects of underground engineering waterproof structures and novel waterproof materials is lacked at present. The device comprises a left fixed test block and a right fixed test block which are fixed on a corresponding base or a corresponding terrace, wherein a deformation joint used for being filled with a pasty water stop material is formed between the left fixed test block and the right fixed test block; a water injection cavity is formed in the right fixed test block, a corresponding cavity is formed in the left fixed test block, and the water injection cavity and the cavity face an opening of the deformation joint and correspond to each other; a water injection pipe for communicating the water injection cavity with an external water source and a pressure gauge or a pressure sensor for monitoring the water pressure in the water injection cavity are arranged on the right fixed test block. According to the device, the hydraulic pressure bearing capacity test is carried out by giving different hydraulic pressure variables to the deformation joint pasty body water-stop material, so the waterproof pressure-bearing effect of the deformation joint pasty body water-stop material is detected, and the limit parameters of the hydraulic pressure bearing capacity of the deformation joint pasty body water-stop material in the normal water-stop state of the deformation joint can be accurately obtained.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a waterproof performance simulation test device and method for paste waterproof materials. Background technique [0002] In the process of accelerating urbanization in our country, construction projects are gradually developing into the underground field. The most common quality problem in underground construction is leakage, so waterproofing plays a key role in underground construction. Detailed waterproofing is the key point in underground waterproofing projects. Deformation joints are the weak link in waterproofing of underground detailed structures. Once water seepage occurs, on the one hand, it will accelerate the deterioration of the underground building space environment, affect the normal use of underground construction projects, and bring great harm to the anti-seepage maintenance. It must be difficult; on the other hand, it seriously threatens the safe...
