Detailed Description
The invention is described in further detail below with reference to the figures and the embodiments.
As shown in figures 1 and 2, the anti-seepage device for the structural joint of the elevator shaft and the dam body at the connecting section of the dam comprises grooves 2 formed in two sides of the top of the structural joint 1, a plate 10 is obliquely buckled in the grooves 2, sealant 3 is arranged at the contact position of two ends of the plate 10 and the grooves 2, and a cement mortar layer 4, a waterproof roll material layer 5 and a concrete surface layer 6 are sequentially paved on the upper side of the plate 10.
Preferably, one of the side pockets 2 opens in the side wall of the elevator shaft 7 near the structural joint 1, and the other side pocket 2 opens in the side wall of the dam 8 near the structural joint 1.
Preferably, the plate 10 is a stainless steel plate, and the sealant 3 is a polysulfide sealant. After the design, two ends of the plate 10 can be sealed through the sealant 3, so that the plugging process is realized.
Preferably, the waterproof coiled material layer 5 is an SBS modified asphalt waterproof coiled material, one side of the waterproof coiled material is lapped on the side wall of the elevator shaft 7, and the other side of the waterproof coiled material extends to the step of the dam body 8. In this embodiment, the waterproof roll layer 5 is made of 2 SBS modified asphalt waterproof rolls with a thickness of 3mm, so as to further achieve the waterproof and anti-seepage effects.
Preferably, a slope is arranged on the top of the concrete surface layer 6. In this embodiment, the concrete surface layer 6 may be a poured C25 concrete surface layer, and the slope surface is provided with a proper hydraulic slope for natural drainage.
Preferably, a rain baffle 9 is obliquely arranged between the top surface of the concrete surface layer 6 and the side wall of the elevator shaft 7. The rain baffle 9 can effectively prevent rainwater from dripping into a gap possibly existing between the top surface of the concrete surface layer 6 and the side wall of the elevator shaft 7, and the rain baffle 9 can play a role in drainage after being obliquely arranged, so that rainwater is effectively prevented from entering the gap.
Preferably, the rain baffle 9 comprises an inclined plate 9.1 obliquely inserted into the side wall of the elevator shaft 7, the lower side of the inclined plate 9.1 is fixedly connected with the top of a vertical plate 9.2, the bottom of the vertical plate 9.2 is connected with the top of a spring 9.4 through a pressing block 9.3, and the bottom of the spring 9.4 is in contact with the top surface of the concrete surface layer 6.
