The invention provides a foundation pit anchor cable opening device and a foundation pit anchor cable opening construction method. Among them, the foundation pit anchor cable opening device includes: a casing, a sealing layer and two annular seals; the casing is used to be placed in the opening of the support pile, and the gap between the outer wall of the casing and the opening is filled. In the plugging layer, the inside of the sleeve is used to pass through the hole-forming tube for the anchor cable; the two sealing elements are respectively connected to the two ends of the sleeve in one-to-one correspondence and are in contact with the hole-forming tube for the anchor cable. In the present invention, the gap between the casing and the opening of the supporting pile is filled with a sealing layer for sealing and reinforcement, which improves the sealing performance and the strength of the opening, avoids hole collapse, and the two casings The ends are equipped with seals, and the two seals are in contact with the anchor cable hole-forming tube, which can seal the gap between the casing and the anchor cable hole-forming tube, effectively improving the anchor cable hole in the foundation pit. The tightness at the place avoids water gushing and sand gushing, ensures the stability and safety of the foundation pit, and has a simple structure and is easy to operate.
Description
technical field [0001] The invention relates to the technical field of construction engineering, in particular to a foundation pit anchor cable opening device and a foundation pit anchor cable opening construction method. Background technique [0002] In the process of deep foundation pit construction in urban construction projects, the foundation pit support type of support pile + mixing pile water-stop curtain + prestressed anchor cable is a more economical and reasonable foundation pit support scheme. Usually, the anchor cable construction adopts the steel casing hole-forming process, and the temporary opening where the steel casing passes through the water-stop curtain has no plugging structure or is only sealed by a seal. Because rivers and coastal alluvial areas have deep sand layers and abundant groundwater, serious hole collapse is prone to occur when anchor cables are constructed to form holes through water-bearing sand layers. Moreover, when the anchor cable hole ...
