Description
Technical Field
[0001] The utility model belongs to the technical field of geotechnical engineering, and specifically relates to an H-shaped retaining structure for slope support. Background Art
[0002] The rapid development of cities has not only led to the emergence of many mountain buildings, but also promoted the continuous deepening and expansion of the scale of excavation projects. The support and protection engineering measures and technologies of hillsides have become a hot topic of research and also constitute an important part of geotechnical engineering. The existing basic support structure has taken shape, including conventional anti-slide piles, retaining walls and other measures.
[0003] With the development and maturity of prefabricated building structure technology, slope support structures have gradually changed from on-site processing to pre-construction in factories. In particular, with the growing demand for rail transit in various cities, slope support has become a popular branch of geotechnical engineering construction. Most of them are prefabricated into H-shaped steel structures that can be inserted into the slope ground to support the soil outside the pit.
[0004] When the H-shaped retaining structure is installed on the slope, in order to make it more stable, anchor cables are often added and inserted obliquely into the soil behind the pile to avoid air and rainwater. However, the inclined channel required by the anchor cables is prone to collapse during the construction process, and the anchor cable tensioning surface is relatively small. Increasing the number of anchor cables will greatly increase the cost and workload, resulting in the H-shaped retaining structure and the soil behind the pile not being tightly connected. For this reason, we propose an H-shaped retaining structure for slope support. Utility Model Content
[0005] The purpose of this utility model is to provide an H-shaped retaining structure for slope support, which can increase the connection area between the H-shaped retaining structure and the slope without the need for additional welding steps, and facilitate the close connection between the H-shaped retaining structure and the soil behind the pile.
[0006] The technical solutions adopted in this utility are as follows:
[0007] A slope support H-shaped retaining structure comprises two crown beams, a plurality of front row piles and a plurality of rear row piles are fixed to the lower surfaces of the two crown beams, a plurality of connecting beams are fixed between the sides of the two crown beams close to each other, a woven net and two groups of steel rings fixedly connected to the woven net are arranged below the two crown beams, the front row piles and the rear row piles are respectively passed through the two groups of steel rings, when constructing the H-shaped retaining structure, the woven net is first laid flat, the steel rings are made to overlap with the holes of the slope, and the plurality of front row piles and the rear row piles are passed through the steel rings one by one and toward Insert it into the hole on the slope, use bolts to fix the two crown beams to the front and rear piles respectively, weld the two crown beams to fix several connecting beams to form an H-shaped retaining structure, and then, unlike the traditional slope protection net, vertical grooves are made on the slope and one end of the woven net is buried. This way, the vertical grooves are not easy to collapse, the construction difficulty is small, and the connection area between the H-shaped retaining structure and the slope can be increased. Moreover, the woven net and steel ring can be put on and used without additional welding steps, which facilitates the close connection between the H-shaped support structure and the soil behind the piles.
[0008] A steel plate is fixed on one side of the braided mesh away from the crown beam. The width of the steel plate is greater than the thickness of the braided mesh. The steel plate is also buried in the vertical slots to facilitate vertical tightening of the braided mesh.
[0009] A rubber sheet is fixed to the lower edge of a crown beam close to the steel plate. One side of the rubber sheet is folded upward and adheres to the outer side of the adjacent crown beam, wrapping the sharper edge of the crown beam to prevent the woven mesh from being cut.
[0010] The side of the woven net close to the front row of piles is sewn and installed with an edge, and the edge can be made of rubber material to enhance the toughness of the side of the woven net and reduce the occurrence of edge breakage.
[0011] Small rods are fixed on the lower surface of the connecting beams, and the lower ends of the small rods pass through the holes of the woven mesh, thereby increasing the supporting points of the H-shaped supporting structure and the woven mesh and improving the firmness of the two structures.
[0012] Inner plastic rings are fixed on the inner sides of the two groups of steel rings to separate the front row piles and the rear row piles from the steel rings to prevent direct friction with the anti-rust coating on the surface of the steel rings.
[0013] The technical effects achieved by this utility model are:
[0014] The utility model discloses an H-shaped retaining structure for slope support. When constructing the H-shaped retaining structure, the woven mesh is first spread flat, and the steel ring is made to overlap with the hole of the slope. A plurality of front-row piles and rear-row piles are passed through the steel ring one by one and inserted downward into the hole of the slope. Two crown beams are respectively fixed to the top of the front-row piles and the rear-row piles with bolts. A plurality of connecting beams are fixed by welding the two crown beams to form an H-shaped retaining structure. Then, unlike the traditional slope protection net, a vertical groove is opened on the slope, and one end of the woven mesh is buried. In this way, the vertical groove is not easy to collapse, the construction difficulty is small, and the connection area between the H-shaped retaining structure and the slope can be increased. Moreover, the woven mesh and the steel ring can be put on and used without additional welding steps, so that the H-shaped retaining structure is conveniently connected to the soil behind the piles.

Moreover, the woven mesh 5 and the steel ring 6 can be put on and used, without the need for additional welding steps, which facilitates the close connection between the H-shaped support structure and the soil behind the piles.
[0023] Among them, soil or gravel can be placed above the woven net 5 for further reinforcement, or flowers and plants can be planted, and the plant roots can be used to grasp the soil behind the piles. Steel rings 6 are used to support the woven net 5 on the front and rear piles 2, 3, which can strengthen the holes of the woven net 5 and reduce the occurrence of cracking or broken edges.
