A method for repairing the leakage of concentration pool and water pool

Abstract

The invention discloses a method for repairing seepage of a concentration tank and a water tank. The method comprises the following steps of: digging a groove at a seeped part, and flushing the basic layer surface of the groove cleanly with water; fixing grouting pipes in the dug groove in sections; filling and leveling up the groove by virtue of an accelerating unit for twice, and compacting with force; injecting polyurethane into the grouting pipes by virtue of a grouting pump; cutting off the grouting pipes after an accelerating agent is concreted; adhering foamed plastic strips on the accelerating agent; filling a polysulfide rubber caulking compound to a groove gap from two sides to the middle part; plastering waterproof mortar; and coating an XYPEX (XYPEX Chemical Corporation) concentrated solution. After waterproof treatment is carried out on the concentration tank by use of a grouting method, original linear flow water seepage and wetting phenomena of the walls and base plate of the water tank do not generate, thus reasons of water seepage of the walls and the base plate are judged correctly, a water seepage treatment method is correct, and the waterproof treatment on the water tank is also successful.

Description

technical field [0001] The invention relates to a construction method, in particular to a method for repairing leakage of concentration pools and water pools. Background technique [0002] Concentration pools and water pools are widely used in mine construction, and the waterproofing of large-volume concrete in the concentration pool has always been a difficult problem in construction. The thickening tank has a large shape and a thin concrete tank wall. There are ten pools and nine leaks in terms of impermeability and waterproofing. Plugging phenomenon. The main reasons for the leakage of the concentration tank and the water pool are as follows: ① Commercial concrete is used during the concrete pouring period. Because it is far away from the mixing station, the joint between the concrete and the bottom concrete is not treated in time after entering the site, and the upper and lower concrete are not combined after pouring. Dense. ②Steel formwork is used for support, and t...

The thickening tank has a large shape and a thin concrete tank wall. There are ten pools and nine leaks in terms of impermeability and waterproofing. Plugging phenomenon

The main reasons for the leakage of the concentration tank and the water pool are as follows: ① Commercial concrete is used during the concrete pouring period. Because it is far away from the mixing station, the joint between the concrete and the bottom concrete is not treated in time after entering the site, and the upper and lower concrete are not combined after pouring. Dense

②Steel formwork is used for support, and the gap between the formwork and the formwork lacks sponge strips, resulting in concrete grout leakage, thereby reducing the impermeability of the concrete

③ The amount of cement and fly ash used in the concrete mixing station is not appropriate, the heat of hydration of the concrete is high, no retarding water reducer is added to the concrete, the temperature is high during construction, and the maintenance of the pool wall after the formwork is removed is not timely, resulting in the inside of the concrete The temperature is high, and the temperature difference between the inside and outside is large, and the concrete has micro-cracks
