Description

Technical Field

[0001] This utility model relates to the field of geotechnical engineering technology, and more specifically to a temporary support structure for slope excavation. Background Technology

[0002] Slope protection refers to the measures taken to support, reinforce, and protect slopes to ensure their safety and that of their environment. Commonly used support structures include: gravity retaining walls, buttress retaining walls, cantilever supports, ribbed or lattice anchored retaining walls, pile anchored retaining walls, shotcrete supports, and the slope ratio method. These methods are generally permanent or long-term support methods. However, during slope engineering construction, when it is necessary to ensure the safety of the construction area but permanent support is not suitable, temporary slope protection is required as an auxiliary measure before the implementation of formal support measures.

[0003] In existing technologies, temporary slope protection generally uses forms derived from formal protection methods, such as anchor spraying support, which is costly and involves many construction procedures. Utility Model Content

[0024] The first embodiment of this utility model is as follows:

[0025] A temporary support structure for slope excavation includes a geotextile assembly 2 laid on the surface, a steel reinforcement assembly arranged on the upper part of the geotextile assembly 2, and an anchor assembly 5 connecting the geotextile assembly 2, the steel reinforcement assembly and the soil 1 into one unit. The upper part of the geotextile assembly 2 covers the upper part of the slope top of the soil 1 and then extends down the slope to the bottom.

[0026] The geotextile component 2 includes geotextile 21, the inner layer of which is also provided with a waterproof layer to improve rainwater resistance, effectively inhibit soil erosion and weathering, increase slope stability, increase soil and water conservation capacity, and prevent water erosion. The geotextile 21 has several through holes 23 evenly distributed on it, and iron rings 24 are set at the through holes 23. The iron rings 24 seal the edges of the through holes 23 to form a stable ring structure, so that the stress at the edges of the through holes 23 of the geotextile 21 is directly applied to the iron rings 24, which strengthens the structural strength at the through holes 23 and prevents tearing caused by the pulling of steel wires 22. Steel wires 22 are set between adjacent iron rings 24. Through the connection of the iron wires and iron rings 24, a square mesh of steel wires 22 is formed, which can increase the tensile strength of the slope, prevent the landslide and collapse of the soil 1, and can also be used to support the soil 1 of the slope, thereby improving the overall stability of the slope.

[0027] The reinforcing steel assembly includes several horizontal reinforcing bars 3 and several vertical reinforcing bars 4. The horizontal reinforcing bars 3 and vertical reinforcing bars 4 are located near the iron ring 24. The horizontal reinforcing bars 3 and vertical reinforcing bars 4 form a grid structure in a crisscross pattern. The anchor assembly 5 includes an integrally formed anchor 52 and a bend 51. The bend 51 is located at the top of the anchor 52 and at the intersection of the horizontal reinforcing bars 3 and vertical reinforcing bars 4, and fastens the horizontal reinforcing bars 3 and vertical reinforcing bars 4 together. The anchor 52 passes through the iron ring 24 and is inserted into the soil 1. The horizontal reinforcing bars 3, vertical reinforcing bars 4 and anchor 52 are all perpendicular to each other. The anchor assembly 5 also includes a fixing buckle 6, which passes around the bend 51, the horizontal reinforcing bars 3 and the vertical reinforcing bars 4 and fixes the three together.

[0028] The vertical reinforcement 4 includes straight reinforcement and bent reinforcement. The straight reinforcement is placed at the top of the slope and the slope, and the bent reinforcement is placed at the junction of the top of the slope and the slope. The straight reinforcement and the bent reinforcement are connected by welding to adapt to the shape of the slope and enhance the overall stability.

[0029] A rigid support system is formed by steel reinforcement components and anchor components 5, and geotextile components 2 are fixed inside it to form a complete three-dimensional support system. This system can effectively increase the stability of the slope, absorb the slope's geological benefits, distribute the load on the slope, and reduce the slope's tendency to slide.
