The invention provides a thermal power plant water cooling tower pressure ditch deformation joint leaking stoppage device and method, and belongs to the technical field of water cooling tower pressure ditch deformation joint leaking stoppage. The leaking stoppage device comprises a first water leakage-proof layer, a water stopping rubber strip, a second water leakage-proof layer, a waterproof coiled material, a steel protection plate and a three-cloth three-oil waterproof layer which are arranged in the pressure ditch deformation joint and at the upper end of the pressure ditch deformation joint alternately. According to the leaking stoppage device and method for the deformation joint of the pressure ditch of the water cooling tower of the thermal power plant, three rigid sealing waterproof layers and three flexible sealing waterproof layers are used in a crossed mode, the waterproof effect is good, the deformation joint does not leak water, the technical problem that the leaking stoppage effect of the deformation joint of the pressure ditch is poor is solved, and the leaking stoppage effect of the deformation joint of the pressure ditch is improved. Compared with a plugging scheme in the prior art, the plugging device has the technical effects of good effect, durability in use, no need of later maintenance and easiness in plugging operation.
Description
technical field [0001] The invention belongs to the technical field of leakage plugging of deformation joints of pressure grooves of cooling towers, and more specifically relates to a leakage plugging device and method for deformation seams of pressure grooves of cooling towers in thermal power plants. Background technique [0002] The pressure channel of the cooling tower is usually a concrete square ditch, and it can also be a pressure square ditch. Water leaks often occur. The reasons for water leakage are as follows: because the square ditch is heavy and has poor deformation resistance, the foundation of the square ditch is not firm, and it is prone to uneven settlement due to groundwater soaking. In order to prevent the square ditch from cracking, rubber stoppers are buried between the expansion joints of the square ditch. The water belt, but the settlement of the pressure groove is greater than the deformation resistance of the rubber waterstop, and the cracking of th...
