Abstract
Description
Technical Field
[0001] The utility model relates to the field of construction, in particular to an anchor lock and anchoring structure for a deep foundation pit in a sandy stratum. Background Art
[0002] The function of retaining piles is to block the earthwork of the road outside the foundation pit after the foundation pit is excavated to protect the safety of the construction inside the foundation pit. At the same time, the maintenance piles also have the effect of stopping water, which can prevent the peripheral water from flowing into the foundation pit. Traditional retaining piles are more suitable for hard strata. For sandy strata, the tensile strength of the anchor cable is low and the retaining piles are prone to tipping. Utility Model Content
[0003] The utility model aims to provide an anchor lock and anchoring structure for a deep foundation pit in a sandy stratum where a retaining pile is not easy to topple over.
[0004] To achieve the above purpose, the technical solution of the utility model is:
[0005] The utility model discloses an anchor lock and anchoring structure for a deep foundation pit in a sandy stratum, comprising a guard pile, a crown beam, an anchor pile and a plurality of anchor cables; the lower end of the guard pile is fixed in the foundation pit, the crown beam is fixedly installed on the top of the guard pile, the anchor pile is fixed in the soil layer outside the foundation pit and is located on the outside of the guard pile, the upper ends of the plurality of anchor cables are fixed on the crown beam, and the lower ends of the plurality of anchor cables are fixed on the anchor pile.
[0006] The upper part of the anchor pile is provided with an oblique through hole, and the lower end of the anchor cable is fixedly inserted into the oblique through hole in the upper part of the anchor pile.
[0007] The anchor cable includes an anchor cable body, multiple plastic sleeves, an isolation frame, multiple steel strands, and an anchor rod body; the multiple plastic sleeves are arranged in the anchor cable body at intervals, and isolation frames for isolating the plastic sleeves are arranged between the multiple plastic sleeves. The multiple steel strands are respectively inserted into the multiple plastic sleeves at intervals, and one end of the multiple steel strands is fixed to the anchor rod body.
[0008] The anchor cable body is made of cement slurry.
[0009] The anchor rod body includes a corrugated pipe, an anchor pad, an anchor plate, and a spiral steel bar; the anchor pad is fixedly sleeved on the corrugated pipe, one end of the anchor plate is fixed on the anchor pad, the other end of the anchor plate is connected to the steel strand, and the spiral steel bar is wrapped around the outer wall of the anchor pad.
[0010] A deep groove is opened in the soil layer outside the foundation pit, anchor piles are fixed at the bottom of the deep groove, and the upper part of the deep groove is an empty pile.
[0011] After adopting the above scheme, since the utility model includes retaining piles, crown beams, anchor piles, and multiple anchor cables, the two ends of the multiple anchor cables are firmly connected to the crown beams and the anchor piles, so that the retaining piles fixed to the crown beams are firmly pulled by the anchor cables, and the anchor cables have high tensile strength, which effectively prevents the retaining piles from tipping over.
[0012] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] like Figure 1 , Figure 2 As shown, the utility model is an anchor lock and anchoring structure for a deep foundation pit in a sandy stratum, comprising a retaining pile 1, a crown beam 2, an anchor pile 3, and a plurality of anchor cables 4.
[0020] The lower end of the retaining pile 1 is fixed in the foundation pit, the crown beam 2 is fixedly installed on the top of the retaining pile 1, a deep groove 101 is opened on the sandy soil layer outside the foundation pit, the anchor pile 3 is fixed at the bottom of the deep groove 101 and is located on the outside of the retaining pile 1, the upper part of the deep groove 101 is an empty pile 5, the upper ends of multiple anchor cables 4 are fixed on the crown beam 2, and the lower ends of the multiple anchor cables 4 are fixed on the anchor pile 3.
[0021] The anchor pile 3 has an oblique through hole 31 on the upper part, and the lower end of the anchor cable 4 is fixedly inserted into the oblique through hole on the upper part of the anchor pile. In this embodiment, the lower end of the anchor cable 4 is fixed by cement slurry poured into the oblique through hole of the anchor pile.
[0022] like Figure 3 , Figure 4As shown, the anchor cable 4 includes an anchor cable body 41, multiple plastic sleeves 42, an isolation frame 43, multiple steel strands 44, and an anchor rod body 45; the multiple plastic sleeves 42 are arranged in the anchor cable body 41 at intervals, and isolation frames 43 for isolating the plastic sleeves 41 are arranged between the multiple plastic sleeves 42, and multiple steel strands 44 are respectively interspersed in the multiple plastic sleeves 42, and one end of the multiple steel strands 44 is fixed on the anchor rod body 45.
[0023] The anchor body 41 is made of cement slurry.
[0024] The anchor rod body 45 includes a corrugated tube 451, an anchor plate 452, an anchor plate 453, and a spiral steel bar 454; the anchor plate 452 is fixedly sleeved on the corrugated tube 451, one end of the anchor plate 453 is fixed on the anchor plate 452, the other end of the anchor plate 453 is connected to the steel strand 44, and the spiral steel bar 454 is wrapped around the outer wall of the anchor plate 452.
