Embodiment approach
[0063] As another preferred embodiment of the construction method of the present invention, the construction method also includes: fixedly connecting the reinforcement plates 22 on the adjacent water-stop steel molds 21, and adopting a sealed connection to form a closed ring, so that a On the one hand, the structural strength and rigidity of the water-stop steel mold 21 can be improved, and on the other hand, it also has the function of water-stop. Preferably, the reinforcing plate 22 is an L-shaped plate, including a first wing plate and a second wing plate vertically connected to each other, the first wing plate is attached to the surface of the water-stop steel mold 21 and sealed with the water-stop steel mold 21 connected, the second wing plate is perpendicular to the surface of the waterproof steel mold 21, and the second wing plate is located above the first wing plate. The L-shaped plate is preferably angle steel, and when connected with the water-stop steel mold, full ...

The invention relates to a steel plate concrete combined anti-floating water stop structure and a construction method. The structure comprises overbreak space, a plurality of water stop steel dies, a plurality of strengthening plates, water stop plates and an anti-floating structure. The overbreak space is excavated and formed below the pit bottom of a foundation pit, and the edge of the overbreak space is located on the outer side of the edge of the pit bottom. The height of the water stop steel dies is larger than the water level elevation of the foundation pit, the multiple water stop steel dies are connected in an end-to-end manner and define a square frame structure located in the overbreak space, and the edge of the square frame structure is located on the outer side of the edge of the pit bottom of the foundation pit. The strengthening plates are fixedly arranged on the inner side faces and the outer side faces of the water stop steel dies at intervals. The water stop plates are fixedly arranged on the inner side faces of the water stop steel dies and located in the overbreak space. The anti-floating structure is poured and formed in the overbreak space, and the bottom of the square frame structure, part of the strengthening plates and the water stop plates are anchored through the anti-floating structure. Through combination of the anti-floating structure and the water stop steel dies, good floating resisting and water stopping functions are achieved, and a safety guarantee is provided for construction of the foundation pit.
Description
technical field [0001] The invention relates to the field of building construction, in particular to a steel plate concrete combined anti-floating water-stop structure and a construction method thereof. Background technique [0002] At present, more and more underground spaces are used for construction, and foundation pits are getting deeper and deeper. To meet the needs of building functions, there are many deep pits in large foundation pits. During foundation pit construction, such as elevator pits and sump pits Effective water stop in the middle of the construction of foundation pits such as caps and caps has always been a problem that is difficult to solve. [0003] China's prior patent (application number: 201511010921.7, invention name: support box and construction method under the condition of deep pit overexcavation) discloses a support box and construction method under the condition of deep pit overexcavation, specifically its In the over-excavation part of the dee...
