Background
The dam water collecting well is a collection position of dam and foundation seepage water, water collected in the water collecting well is pumped and discharged to the dam through the arranged water suction pump, the pump house is a building structure which is specially arranged on a rear cantilever structure of the dam for placing the water suction pump, and the main function of the building structure is to place the water pump. The pump house foundation is generally poured together with the dam body as a bracket of the dam body, but the upper structure of the pump house is a concrete frame structure for later construction, so a construction joint exists between the pump house structure and the dam body. The arch dam belongs to a large-volume concrete structure, a surface hole, a deep hole or a bottom hole is generally arranged on a dam body for reservoir water flood discharge, a pump house is generally arranged in the center of a river channel along with a water collecting well, the position of the pump house is basically arranged below an orifice of the dam body, the water mist generated by flood discharge of the dam body is stronger in rain intensity than rainstorm, a large amount of electrical equipment is generally arranged in the pump house, and therefore, the roof water prevention of the pump house is an important consideration factor in the design of the pump house.
The commonly adopted roof waterproof measure of the pump house at present is to arrange a very thin cover on the upper part of the joint part of the pump house and the dam body, the thickness of the cover is generally several centimeters, the cover is similar to the function of an eave, and meanwhile, the joint part is coated with waterproof materials to prevent seepage; meanwhile, the roof surface adopts 2% of slope to accelerate the drainage of the accumulated water on the roof. However, because the difference of concrete materials of the joint part is large, the concrete grade of the dam body is generally high, and the grade of concrete of the roof is low, so that the construction joint of the joint part is opened due to uneven thermal expansion and cold contraction, and the opening degree of the construction joint is increased due to the vibration of the dam body when the dam body discharges flood. Rain-proof covers has certain effect to perpendicular rain drop, nevertheless to the rainwater reinforce too big and there is not protective effect at the ponding of roof formation almost, and ponding can be followed infiltration in the open construction joint, influences pump house normal use. Meanwhile, the eave structure is small and thin in size, field protection is often ignored or not in place, and the eave structure is often damaged, so that the waterproof effect is further reduced.
