Description

Technical Field

[0001] The utility model relates to the technical field of slope management, in particular to a steel pipe pile anchor bar piling device for slope landslide management and reinforcement. Background Art

[0002] The topsoil layer of the slope is slightly thin, and the dolomite limestone in the lower part is relatively hard, with developed joints and fissures and broken rock mass. After excavation, the shallow slope becomes an earth slope with loose soil. Because it is formed by colluvial slope, there is local overhead phenomenon and poor stability of the topsoil. After the slope is excavated, the shallow surface is a pure earth slope, which is prone to landslides. If the protection and reinforcement are not proper, a working landslide may occur. The lower part is a stone slope with developed joints and fissures. The joints and fissures cut the rock layer into a fragmented mosaic structure. The overall stability of the rock slope in the lower part is good, but the cross slope is steep and the shallow rock mass is very broken, and large wedge-shaped collapse damage may occur along the structural surface. The steel pipe pile anchor reinforcement piling device is a device used to fix steel pipe piles on the ground. It can drive the steel pipe piles into the underground soil through a pile driver and connect them to the foundation through steel bars to enhance the stability of the building. The device is usually composed of a pile driver, a drill bit, a clamp and other parts. It can quickly and efficiently fix steel pipe piles deep in the foundation, thereby improving the seismic resistance of the building. When controlling slope landslides, a steel pipe pile anchor reinforcement piling device is needed to protect the slope.

[0003] In order to effectively control the horizontal displacement of the mountain during the excavation of the tunnel portal section and reduce the impact of terrain bias on the structure of the arch tunnel and the stability of the slope, effective surface reinforcement measures need to be added. Considering the stability of the steep slope, the best effect is to set up anti-slide piles. However, this solution takes too long to meet the project progress requirements. Utility Model Content

[0004] The utility model aims to provide a steel pipe pile anchor bar piling device for slope landslide treatment and reinforcement, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel pipe pile anchor bar piling device for slope landslide control and reinforcement, comprising a slope body, and also comprising a steel pipe pile arranged on the top of the slope body for reinforcing the mountain, the steel pipe pile comprising a first steel pipe inserted into the inner wall of the slope body, the inner wall of the first steel pipe is provided with a grouting hole, the inner wall of the first steel pipe is fixedly connected with a positioning bar, one side of the positioning bar is fixedly connected with three bundled steel bars, the steel bars are welded with welds, and the inner wall of the first steel pipe is provided with a filling layer for grouting.

[0006] Preferably, a connecting sleeve is fixedly connected to the outer side of the first steel pipe, and the connecting sleeve is used for welding the first steel pipes.

[0007] Preferably, a conical head is fixedly connected to the bottom end of the first steel pipe, and the conical head is used to improve the stability of the connection with the inner wall of the slope body.

[0008] Preferably, an I-beam is fixedly connected to the top of the first steel pipe, and a diagonal steel is fixedly connected to the outer side of the I-beam.

[0009] Preferably, a first casting hole is opened at the downslope of the top of the slope body, and the bottom end of the first steel pipe is inserted into the inner wall of the first casting hole.

[0010] Preferably, a second casting hole is opened at the upslope of the top of the slope body, a second steel pipe is inserted into the inner wall of the second casting hole, and the top of the second steel pipe is fixedly connected with the anchor bar body.

[0011] Preferably, the inner wall of the slope body is provided with a tunnel hole for facilitating the passage of vehicles.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model sets a pile foundation steel pipe, and pressure is used to inject cement mortar into the pipe. The cement mortar penetrates, squeezes and solidifies into the soil around the pile through regular slurry outlet holes on the steel pipe, so that the soil within a certain range around the pile is reinforced, and a composite soil of steel pipe anchor bars + cement mortar is formed near the pile, thereby improving the shear strength of the soil. Its biggest feature is that a part of the sliding body of the slope is reinforced into an anti-sliding body to achieve the purpose of landslide control. The steel pipe column anchor bar mainly plays the role of reinforcing and seismic resistance of the sliding surface of the slope through anti-sliding effect, compaction reinforcement effect, and pile-soil composite effect, which solves the problem of adding effective surface reinforcement measures to effectively control the horizontal displacement of the mountain during the excavation of the tunnel portal section and reduce the influence of terrain bias on the structure of the arch tunnel and the stability of the slope. Considering the stability of the steep slope mountain, the best effect is to set up anti-sliding piles. However, the construction period of this solution is too long and cannot meet the requirements of the project progress. BRIEF DESCRIPTION OF THE DRAWINGS
