Abstract
Description
Technical Field
[0001] This utility model relates to the field of foundation pit construction technology, specifically to a double-row pile support structure that can be constructed with large-angle anchor rods. Background Technology
[0002] In the fields of foundation pit engineering and slope protection, double-row pile support structures are widely used in various civil engineering constructions due to their good overall rigidity and deformation resistance. Through the coordinated work of the front row of piles, the rear row of piles, and the connecting beam, the double-row pile support structure can effectively resist the lateral pressure of the soil and ensure the safety of construction. To further improve the support effect, the combination of anchor bolts and double-row piles is often used. The anchor bolts are used to transfer the load on the double-row piles to the deep stable soil, thereby enhancing the stability of the support structure.
[0003] In actual construction, traditional double-row pile support structures face many challenges when installing anchor bolts at large angles. The existing connection structure between the anchor bolts and the double-row piles is fixed, making it difficult to flexibly adjust the anchor bolt angle according to complex geological conditions and engineering design requirements. This results in the anchor bolts not being able to be accurately anchored to the ideal soil layer, greatly reducing the anchoring effect and failing to fully utilize the stability and bearing capacity of the support structure. Utility Model Content

[0006] The adjustment mechanism includes a connecting frame disposed on the front of the front row of piles. The connecting frame has an outer arc-shaped plate, and the inner side of the arc-shaped plate has a threaded connecting block with a bolt.

[0008] Preferably, the inner side of the connecting frame is provided with a limiting groove corresponding to the movement trajectory of the slider, and the slider is slidably connected inside the limiting groove. The limiting groove can limit the slider, making the slider more stable during movement.

Through the fixing hole, the rotating shaft can rotate inside the support plate, and the rotating shaft can drive the linkage rod and the guide cylinder to rotate through the fixing plate, so that the tilt angle of the guide cylinder can be adjusted.
[0012] Preferably, the guide tube has a through hole corresponding to the anchor rod body on its inner side, and the anchor rod body is slidably connected to the inner side of the through hole. The guide tube can limit the anchor rod body, so that the anchor rod body can be accurately driven into the soil at a predetermined angle and direction, effectively improving the construction angle accuracy of the anchor rod body and reducing the problem of poor anchoring effect caused by angle deviation.
[0013] Compared with the prior art, this utility model provides a double-row pile support structure that allows for the installation of large-angle anchor bolts, and has the following beneficial effects:
[0014] 1. This double-row pile support structure with large-angle anchor rods has an adjustment mechanism.
