Description

Technical Field

[0001] This utility model relates to the technical field of foundation pit support, and in particular to an adjustable foundation pit anchor cable support rib structure suitable for confined spaces. Background Technology

[0002] The main function of foundation pit support structures is to resist lateral earth pressure on the foundation pit, prevent deformation of the pit walls, and ensure construction safety. However, in urban environments, especially in confined spaces or sensitive areas, traditional foundation pit support methods (such as cast-in-place piles with internal bracing, diaphragm wall support, etc.) have many limitations, such as high construction difficulty, high cost, and significant impact on the surrounding environment.

[0003] In recent years, with the development of construction technology, adjustable prestressed devices and anchor cable support structures have gradually become effective means to solve these problems. For example, adjustable prestressed devices can effectively save foundation pit space, improve construction efficiency, and also have certain recycling value. In addition, anchor cable support technology enhances the anchoring effect through grouting, significantly improving the stability and economy of foundation pit support.

[0004] However, the design and construction of foundation pit support structures face more challenges in confined spaces. These include limited construction space, dense surrounding buildings, and difficulties in deploying construction equipment. Traditional support structures often struggle to adapt to these complex conditions, necessitating the development of a support structure that can meet the requirements of construction in confined spaces while also being flexible enough to adapt to different foundation pit shapes and geological conditions.

[0005] Furthermore, although adjustable tension angle anchor supports have been developed in existing technologies, the ease of assembly, disassembly, and adjustment of the support structure in confined spaces remains a problem that urgently needs to be solved. Therefore, developing an adjustable anchor support rib structure for foundation pits suitable for confined spaces can not only improve construction efficiency but also effectively reduce construction risks, which has significant practical implications. Summary of the Invention

[0006] The purpose of this invention is to provide an adjustable foundation pit anchor cable support rib structure suitable for confined spaces, in order to solve the above-mentioned problems.

[0007] This utility model is achieved through the following technical solution:

[0010] Anchor cable, an anchor point that connects to the main body of the support rib and extends to the side wall of the pit;

[0011] An adjustable connection component is located between the support rib body and the anchor cable to adjust the relative position and tension between the support rib body and the anchor cable.

[0012] In one possible design, the adjustable connection assembly includes an anchor cable fixing sleeve, an adjusting nut, a connecting plate, and a toothed plate. The anchor cable fixing sleeve is fixed to the exposed end of the anchor cable. The adjusting nut is threaded into the anchor cable fixing sleeve. The connecting plate is ball-jointed with the adjusting nut. The toothed plate is fixed to the support rib body. One side of the toothed plate has evenly distributed strip teeth. The connecting plate has strip teeth that mate with the toothed plate.

[0013] In one possible design, the adjusting nut includes a hexagonal nut part and a ball head part. The ball head part is ball-hinged with the connecting plate. The end of the anchor cable fixing sleeve away from the adjusting nut is also fixedly provided with a hexagonal nut.

[0014] In one possible design, the support rib body includes multiple first rib units and multiple second rib units. Adjacent first rib units are connected by multiple second rib units. A connector is fixed on the second rib unit. The connector is used for quick positioning with the insertion hole between the first rib unit and the locking part uses bolts to fix adjacent first rib units.

[0015] In one possible design, the anchor cable fixing sleeve is provided with scale markings, which are used to indicate the distance the adjusting nut moves, thereby precisely controlling the distance between the support rib body and the anchor cable.

[0016] In one possible design, the connecting plate is provided with a strip-shaped adjustment hole through which the anchor cable passes, thereby achieving avoidance when adjusting the angle between the anchor cable and the support rib body.

[0017] In one possible design, the outer surface of the support rib body is provided with reinforcing ribs, which are used to improve the bending resistance and stability of the support rib body.

[0018] In one possible design, guide devices are provided at both ends of the support rib body, which are used to guide the installation and positioning of the support rib body in a confined space.

[0019] In one possible design, the anchor cable is a prestressed anchor cable, the prestress of which is adjusted by an adjustable connection assembly to accommodate the deformation of the pit sidewall.

[0020] In one possible design, the main body of the support rib is made of high-strength steel, and the adjustable connection component is made of corrosion-resistant material.
