Description

Technical Field

[0001] This utility model belongs to the field of anchor cable support technology, specifically relating to an anchor cable support structure for deep foundation pits. Background Technology

[0002] Deep foundation pit anchor cable support structures, as a common support method in engineering practice, have indeed demonstrated their unique support effectiveness. However, upon closer analysis of their performance, while their support effect is evident to a certain extent, the relatively singular nature of their support function has become a major limitation in their application.

[0003] Faced with complex and ever-changing geological conditions, deep foundation pit anchor cable support structures often fall short. The diversity of geological environments demands that support structures possess greater adaptability and flexibility, while traditional anchor cable support structures clearly have certain shortcomings in this regard. Their design principles and structural features are often unable to fully cope with various emergencies and special geological phenomena, thus limiting their application scope to some extent.

[0004] Furthermore, deep foundation pit anchor cable support structures may also reveal other limitations during use. For example, the support effect may be unsatisfactory for certain special soil layers, or performance degradation may occur under long-term loads. Utility Model Content

[0005] The purpose of this utility model is to provide a deep foundation pit anchor cable support structure to solve the problem mentioned in the background art that the support performance of the deep foundation pit anchor cable support structure is relatively simple and it is difficult to cope with the support needs of complex and ever-changing geological conditions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a deep foundation pit anchor cable support structure, comprising an anchor rod obliquely inserted into the deep foundation pit; a platform is also connected through the end of the anchor rod outside the foundation pit, and steel beams are provided at the upper and lower positions between the platform and the deep foundation pit; a multi-support assembly is provided between the platform and the deep foundation pit, the multi-support assembly comprising: a reinforcement member, disposed between the steel beam and the deep foundation pit; the reinforcement member is partially embedded inside the deep foundation pit, and the reinforcement member is disposed on the upper and lower sides of the anchor rod, which can improve the deformation resistance of the deep foundation pit and ensure the normal use of the anchor rod, thereby achieving the purpose of improving the support strength; and a filler, disposed between the upper and lower steel beams and sleeved on the outside of the anchor rod, which fills the gap between the platform and the deep foundation pit, thereby fully wrapping the area of ​​the anchor rod exposed outside the deep foundation pit, further improving the installation strength of the anchor rod.

[0007] Preferably, the reinforcing member includes a steel plate fixed to the deep foundation pit, with inclined diagonal rods inserted through both ends of the steel plate. The diagonal rods are embedded in the deep foundation pit in a figure-eight shape. Through this insertion, a large area of ​​contact between the steel plate and the deep foundation pit can be achieved, thereby expanding the compressive force on the steel plate outward and reducing the deformation of the deep foundation pit. The steel beam is installed in the middle area of ​​the steel plate and does not contact the diagonal rods.

[0008] Preferably, the platform has alignment grooves at both ends, which are engaged with the outside of the steel beam to achieve a quick connection between the platform and the steel beam. A support beam is also provided on the inner side of the bottom of the platform. The support beam is located at the bottom of the steel beam and supports the steel beam. The inner side of the support beam is in contact with the surface of the steel plate to avoid affecting normal installation.

[0009] Preferably, the filler includes multiple filler plates sleeved on the anchor rod. A screw hole is also provided on the surface of the base, and a clamping screw is screwed into the screw hole. The clamping screw abuts against the filler plates, thereby eliminating the gap between the multiple filler plates, clamping the multiple filler plates together, preventing displacement, and clamping the other end of the filler plate into the deep foundation pit, thereby achieving a stable wrapping of the external area of ​​the anchor rod and improving the overall strength of the anchor rod.

[0010] Preferably, the surface of the filler plate is further provided with reinforcing ribs, which are located in the middle of the filler plate. The reinforcing ribs can improve the overall strength of the filler plate.

[0011] Preferably, the pedestal also has a through hole in the middle, through which the anchor rod passes.

[0012] Preferably, the anchor rod is further fitted with a sleeve, which extends into the deep foundation pit, and an anchor body is formed at the bottom end of the anchor rod by pouring concrete.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By adding multiple support components and introducing various support methods, a more complex and efficient support system is formed to fully adapt to the diverse needs that may arise during foundation pit construction. These multiple support components enhance the overall stability and safety of the support, providing more robust support solutions for different geological conditions and construction challenges. This approach not only overcomes the limitations of the anchor cable support structure itself but also significantly improves the quality and efficiency of the entire foundation pit project, ensuring the smooth progress of the construction process and the stable and reliable final results.
