Spliced deep foundation pit slope protection device

Abstract

The invention discloses a spliced deep foundation pit slope protection device, and belongs to the technical field of cross-sea channel construction. The spliced deep foundation pit slope protection device comprises an upper protection panel and a lower protection panel. Two splicing grooves A are symmetrically formed in the bottom surface of the upper protection panel. Plug-in components are arranged in the splicing grooves A. Two splicing grooves B are symmetrically formed in the top surface of the lower protection panel. Locking components are arranged in the splicing grooves B. The plug-incooperation of the plug-in components and the locking components is used to plug-in and fix the upper protection panel and the lower protection panel. The installation method has a small amount of engineering, low cost, and easy installation. Two buffer pads are welded in a symmetrical structure on the front end surfaces of the upper protection panel and lower protection panel. Polyurethane foam materials and springs A in the buffer pads are used to prevent falling rocks from damaging the two protection panels and improve the impact resistance of a slope protection structure. The device is reasonable in structure design and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of cross-sea channel construction, and more specifically, relates to a spliced ​​deep foundation pit slope protection device. Background technique [0002] In the prior art, the slope surface is generally reinforced by means of lattice reinforcement; the lattice reinforcement technology uses mortar block stones, cast-in-place reinforced concrete or prefabricated prestressed concrete to protect the slope surface, and uses anchor rods to Or a slope reinforcement technology fixed by anchor cables, or the method of building retaining walls along the side of the slope body, the main function is to distribute the remaining sliding force or earth pressure and rock pressure of the slope body to the lattice nodes The anchor rod or anchor cable at the place is then transmitted to the stable formation through the anchor cable, so that the slope body is in a stable state under the anchoring force provided by the anchor ...

[0002] In the prior art, the slope surface is generally reinforced by means of lattice reinforcement; the lattice reinforcement technology uses mortar block stones, cast-in-place reinforced concrete or prefabricated prestressed concrete to protect the slope surface, and uses anchor rods to Or a slope reinforcement technology fixed by anchor cables, or the method of building retaining walls along the side of the slope body, the main function is to distribute the remaining sliding force or earth pressure and rock pressure of the slope body to the lattice nodes The anchor rod or anchor cable at the place is then transmitted to the stable formation through the anchor cable, so that the slope body is in a stable state under the anchoring force provided by the anchor rod or anchor cable, and then the side slope will be affected by the landslide below. Roads cause potential safety hazards; however, due to the need to reinforce the slope by building latticework or retaining walls, the general slope area is relatively large, resulting in the need for a large amount of labor and materials, and the amount of work is large. For steeper slopes Generally speaking, the construction difficulty is relatively high, resulting in high cost in the slope treatment process, and the slope body that has already landslide needs to be reinforced again to ensure the safety of the reinforcement; and these need repeated reinforcement and engineering quantities. Both increase the cost of slope reinforcement and maintenance. If a protective wall is directly built at the foot of the slope to block the landslide, the sand and gravel of the landslide have a certain inertia during the sliding process, which will cause a great impact on the protective wall and cause damage to the protective wall.
