Problems solved by technology
During the anchor cable construction process, it is easy to cause a large amount of water gushing and sand gushing so that the anchor cable cannot be carried out smoothly; a large amount of water seeping into the pit will not only deteriorate the construction conditions, but more seriously will cause the foundation pit to collapse and the bearing capacity of the foundation to decrease. The safety of the foundation pit is threatened all the time

Embodiment Construction
[0026] The invention provides a hanging board for preventing leakage of the side wall of a foundation pit.
[0027] In view of the defects existing in the background technology, especially the problem of the form of pile-anchor enclosure is the most serious, so the specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and using the form of enclosure with two inner supports and pile-anchor as an example. illustrate. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0028] In this embodiment, when carrying out foundation pit protection construction, since there are many boulders backfilled near the sea and coastline, and there is a sand layer with a thickness of about 2.5m distributed just at the first anchor cable level, the common anchor When the anchor cable is used ...

The invention discloses a hanging plate used for preventing leakage of the side wall of a foundation pit. The hanging plate is hung on the inner side of a fender pile by embedding steel bars into the inner side of the fender pile and is a concrete hanging plate, the embedded steel bars penetrate through the hanging plate to be embedded into the fender pile, and the hanging plate is provided with anchor cable holes. When the side wall of the foundation pit leaks, the anchor cable holes are blocked through water stop plates and steel plates, wherein the water stop plates are located between the steel plates and the hanging plate. According to the hanging plate used for preventing leakage of the side wall of the foundation pit, by arranging the hanging plate of a concrete structure, embedding the steel bars into the fender pile and blocking the anchor cable holes through the water stop plates and the steel plates, leakage of the side wall of the foundation pit, water gushing and sand gushing are effectively prevented, normal construction of anchor cables is guaranteed, safety of the foundation pit is guaranteed, and the hanging plate is simple, easy to use, good in practicality and wide in application range.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a hanging board for preventing leakage of the side wall of a foundation pit and a construction method thereof. Background technique [0002] At present, in the case of faster and faster urbanization, more and more building foundation pits are adjacent to the sea, dams, reservoirs, etc. In these areas, the water level outside the foundation pit is often high, and the water pressure outside the foundation pit is high. There are thicker sand layers in some areas, and a large number of boulders are backfilled around the foundation pit, with many voids and strong water permeability. occur. [0003] Under the above-mentioned geological conditions, the problem in the form of pile-anchor enclosure is the most dangerous. During the anchor cable construction process, it is easy to cause a large amount of water gushing and sand gushing so that the anchor cable cannot be carr...
