Problems solved by technology

Due to the uneven subsidence of the foundation, the building is deformed, and the waterstop is pulled beyond the limit and cracked, resulting in water leakage
The problems highlighted by the two are that the vibration of the concrete around the waterstop is not dense, the shrinkage coefficient is large, and there are even gaps left, which leads to the poor concrete wrapping of the waterstop wings, especially the waterstop at the base plate and corners Below, it becomes a channel for leaking water, and pressure water will seep along the gap between the two wings of the waterstop and the concrete
These simple treatment methods are all rigid, with low tensile strength, and are not suitable for the needs of structural deformation. Water seepage still occurs after a short time

Embodiment 1

[0022] Embodiment 1 Rubber bag mud sausage stuffing strip controls leakage method: the soft sticky material (9) in the soft plastic sausage stuffing strip (15) is made of (weight percentage) clay 25%, water 55%, waste oil 19.5%, twelve Sodium alkylbenzene sulfonate 0.35%, sodium carboxymethyl cellulose 0.15%, a little sodium hydroxide, fully mixed and stirred evenly. Pour into the rubber film bag (8) with a thickness of 0.03~0.08 mm and then tightly seal the two ends (13), such as figure 2 shown.

[0023] The clay is kaolin, the main component of which is kaolin (Al 2 o 3 2SiO2 2 2H 2 O) and microcrystalline kaolinite (Al 2 o 3 4SiO2 2 2H 2 O) mainly, microcrystalline kaolinite is also called bentonite, which is an ideal filler with fine particles, significant swelling when exposed to water, high viscosity and plasticity. Water adopts tap water. The oil is waste oil from urban sewers. Additives are emulsifier sodium dodecylbenzene sulfonate and tackifier sodium car...

Embodiment 2

[0026]Embodiment 2 The plastic film bag slime sausage filling method for controlling leakage is basically the same as that of Example 1, except that: 1. The film bag (8) adopts a polyethylene film bag (12) with a thickness of 0.015 to 0.045 mm. 2. The soft sticky material in the soft plastic sausage filling strip (15) adopts oil clay (11), and the formula (percentage by weight) of oil clay (11): muddy clay 30%, No. 10 waste engine oil 14.5%, water 55%, Sodium dodecylbenzenesulfonate 0.35%, sodium carboxymethylcellulose 0.15%. 3. The waterproof adhesive (10) adopts vinylidene chloride copolymer latex, and its mixing ratio is: solid content 50% vinylidene chloride copolymer emulsion 68%, 10% trisodium phosphate solution 7%, 5% polyvinyl alcohol solution 13% , 60% titanium dioxide slurry 12%. Preparation method: Put 10% trisodium phosphate into water and stir until completely dissolved, then add 50% vinylidene chloride copolymer emulsion. Put 5% polyvinyl alcohol into water and...

Abstract

A basement deformation joint seepage prevention and treatment method belongs to the building technology. Soft-plastic materials consisting of clay, water, oil and additive are injected into sealing bags and manufactured into soft-plastic intestine filling strips; waterproof adhesive is coated on the deformation joints and the wall surface of a place in which waterstops are embedded; and then the filing strips chock up the deformed joints and cover elastic trim strips, and finally washers are pressed and fixed by screw caps. The method can easily obtain materials, has low cost, convenient construction, simple installation, high speed, high work efficiency and obvious economic benefit and is suitable for the deformation joint seepage treatment.

Description

technical field [0001] The invention relates to the prevention and control of building leakage, in particular to a method for preventing and controlling leakage of deformation joints in basements by using filler strips, which belongs to the building technology. Background technique [0002] Due to the influence of external conditions and the needs of construction, there are expansion joints, settlement joints and construction joints in underground engineering, and these joints are weak links in preventing water seepage. Due to the rise and fall of temperature, the settlement of the foundation, the shaking of the top of high-rise buildings, earthquakes, etc., all may cause the expansion and contraction deformation of the building. In the south of the Yangtze River, the rainfall is abundant, and the groundwater level is often higher than the bottom plane of the basement. The leakage of deformation joints in underground engineering is one of the most prominent leakage phenomen...
