The first waterproof layer 4 of coiled material is laid on the upper surface of the cushion layer 3, and the first waterproof layer 4 of coiled material adopts styrene-butadiene-styrene rubber modified asphalt waterproof coiled material with the thickness of 4-6 mm, so that a waterproof effect is achieved.
The first concrete layer 5 is arranged on the upper surface of the first waterproof layer 4 of the coiled material, an inverted trapezoidal groove is formed in the position below the post-cast strip 2, the area of a groove opening of the inverted trapezoidal groove needs to be larger than the area of the bottom of the post-cast strip 2, and the first concrete layer 5 is formed by pouring reinforced concrete. The second waterproof roll layer 6 is laid on the upper surface of the first concrete layer 5, and the second waterproof roll layer 6 is made of styrene-butadiene-styrene rubber modified asphalt waterproof rolls and is 3-5 mm thick, so that a secondary waterproof effect is achieved. The double-layer coiled material waterproof layer is arranged and separated by the concrete layer, so that the waterproof performance of the post-cast strip can be improved.
The second concrete layer 7 is arranged on the upper surface of the second waterproof layer 6 of the coiled material, and the second concrete layer 7 is formed by pouring reinforced concrete and has the thickness of about 30 millimeters. The second concrete layer 7 is located the part below the post-cast strip 2 to form a second inverted trapezoidal groove, and the area of the notch of the second inverted trapezoidal groove needs to be larger than the area of the bottom of the post-cast strip 2. And the gravel water filtering layer 8 is arranged in the inverted trapezoidal groove II, a water filtering tank 81 is arranged in the inverted trapezoidal groove II, and the water filtering tank 81 is communicated with the outside through a water discharging pipe 82. When the underground water pressure is strong, the water amount is large, and the permeation of underground water cannot be blocked only by the double-layer coiled material waterproof layer, the broken stone water filtering layer 8 can store the permeated underground water in the water filtering tank 81 and discharge the underground water through the water discharging pipe 82, so that the post-cast strip 2 has no accumulated water, the waterproof performance of the post-cast strip 2 is further improved, and the concrete pouring quality of the post-cast strip 2 is ensured.
As shown in fig. 3, the water filtering tank 81 includes a water collecting frame 811, a water filtering support plate 813, a water filtering plate 814, and a water filtering sub-plate 815. The frame wall of collection frame 811 be equipped with the outlet 812 of drain pipe 82 butt joint, drainage support plate 813 with collection frame 811 top is connected, drainage board 814 with collection frame 811 top just is located drainage support plate 813 lower position is connected, inferior drainage board 815 with collection frame 811 top just is located drainage board 814 lower position is connected.
The drainage support plate 813 is equipped with the drainage hole that the aperture is 10 millimeters, drainage plate 814 is equipped with the drainage hole that the aperture is 6 millimeters, just drainage plate 814 with the interval of drainage support plate 813 is 3 centimeters, inferior drainage plate 815 is equipped with the drainage hole that the aperture is 3 millimeters, just inferior drainage plate 815 with the interval of drainage plate 814 is 3 centimeters.
When the gravel water filtering layer 8 is arranged, the water collecting frame 811 is placed at the bottom of the inverted trapezoidal groove, the water outlet 812 is connected with the water discharging pipe 82 embedded in the first concrete layer 5, the coiled material waterproof layer two 6 and the second concrete layer 7 in a butt joint mode, the secondary water filtering plate 815, the water filtering plate 814 and the water filtering supporting plate 813 are sequentially installed on the water collecting frame 811 from bottom to top, and finally gravel is filled in the inverted trapezoidal groove two and the gravel water filtering layer 8 is compressed. The water filtering support plate 813 plays a role in supporting broken stones and water filtering, when some fine broken stones enter the water filtering tank 81 from the water filtering support plate 813, the small broken stones can be supported and filtered through the water filtering plate 814 and the secondary water filtering plate 815, and the small broken stones are prevented from being filled in the water collecting frame 811 to affect water drainage. In addition, a liquid level detector is disposed in the water collection frame 811, and when the amount of the groundwater collected in the water filter tank 81 reaches a certain amount, a start signal may be sent to an external drainage device to automatically drain the water filter tank 81.
The utility model provides a basement bottom plate post-cast strip waterproof construction still includes spill stagnant water steel sheet 9, and spill stagnant water steel sheet 9 is located 8 inside and its vertical avris of rubble drainage layer extend and get into 1 inside the bottom plate. The gravel water filtering layer 8 is required time for water filtering, if the groundwater water quantity is too large, in the water filtering process, the water can be directly permeated upwards very possibly, and the concave water stopping steel plate 9 can block the groundwater from permeating upwards so as to successfully filter and discharge the groundwater through the water filtering tank 81. In addition, 8 upper surfaces of rubble drainage layer and being located 9 internal positions of spill stagnant water steel sheet have still laid plastic barrier film 10, can further prevent that groundwater from oozing to the waterproof performance in post-cast strip has been improved once more.
In addition, a water stop steel plate 11 is horizontally arranged at the joint of the bottom plate 1 and the post-cast strip 2, and the side of the water stop steel plate 11 is obliquely bent downwards. And a compressive sealant layer is coated on the connecting surface of the bottom plate 1 and the post-cast strip 2. If a small amount of underground water still permeates upwards, the underground water can be completely blocked by the water-stop steel plate 11 and the compressive sealant layer, so that the basement floor post-cast strip waterproof structure has very effective waterproof performance.
