Description
Technical Field
[0001] The utility model relates to a reinforcement structure for mountain slopes, belonging to the field of slope stability. Background Art
[0002] With the acceleration of the urbanization process, the development and utilization of natural resources by humans are becoming increasingly frequent. Especially in the construction activities in mountainous areas, the problem of slope stability has become increasingly prominent.

[0026] The present utility model will be further described below in conjunction with the accompanying drawings through specific embodiments.
[0027] Embodiment 1: A mountain slope reinforcement structure, as Figure 1 shown, includes a lattice beam 1, a retaining wall 2, a first prestressed anchor cable 3, a strengthening beam 4, and a second prestressed anchor cable 5.
[0028] The lattice beam 1 is as in the prior art and is arranged on the slope surface. A plurality of first prestressed anchor cables 3 are arranged on the lattice beam 1. The anchorage section of the first prestressed anchor cable 3 is obliquely anchored into the stable rock mass through the holes of the weak structural plane of the rock mass. The retaining wall 2 is arranged at the bottom of the slope and is connected to the lattice beam 1.
[0029] The strengthening beam 4 is arranged at the top of the slope. If the top of the mountain slope is uneven, it can be leveled in advance. The strengthening beam 4 is connected to the lattice beam 1. A number of second prestressed anchor cables 5 are arranged on the strengthening beam 4. The structure of the second prestressed anchor cable 5, as in the prior art, includes an anchorage section 51 and a free section 52. The anchorage section 51 of the second prestressed anchor cable 5 is vertically anchored into the stable rock mass through the holes of the weak structural plane of the rock mass. The free section 52 of the second prestressed anchor cable 5 passes upward through the strengthening beam 4 and the second prestressed anchor cable 5 is restricted on the strengthening beam 4 by a lock nut 53. An anchor pad 54 is arranged between the lock nut 53 and the strengthening beam 4.
[0030] Compared with the traditional slope reinforcement structure, in this embodiment, the strengthening beam 4 and the second prestressed anchor cable 5 are added at the top of the slope. Multiple building reinforcement structures such as the strengthening beam 4, the second prestressed anchor cable 5, the lattice beam 1, the first prestressed anchor cable 3, and the retaining wall 2 are arranged from the top of the slope to the bottom of the slope and connected into an integral structure, forming a more stable slope support system, which is suitable for complex slopes with higher reinforcement requirements.
[0031] The strengthening beam 4, the lattice beam 1, and the retaining wall 2 are all concrete-cast structures, and the three are connected into an integral cast structure. The integral cast structure has better integrity, greater stiffness, provides better stability and safety, improves the reinforcement effect, and has high construction efficiency of the integral cast structure, thereby improving the construction efficiency of slope reinforcement.
[0032] The lattice beam 1, like the existing lattice beams, has a structure with a plurality of squares arranged in a plurality of rows and columns, and vegetation is planted in the squares to further fix the surface soil of the slope.
[0033] like Figure 2 As shown, the reinforcing beam 4 includes a plurality of longitudinal beam portions 42 and a plurality of transverse beam portions 43. The transverse beam portions 43 are arranged between the longitudinal beam portions 42 and connected to the longitudinal beam portions 42. The longitudinal beam portions 42 are parallel to each other, and the transverse beam portions 43 are parallel to each other. The existence of the longitudinal beam portions 42 and the transverse beam portions 43 enables the reinforcing beam 4 to form a plurality of planting spaces 41. The planting space 41 should be as large as possible, preferably with an area of more than 1 square meter, and preferably with a square shape, so that trees with relatively large diameters and relatively developed root systems can be planted, so as to achieve a better water and soil fixation effect on the top of the slope.
[0034] Embodiment 2, on the basis of embodiment 1, as Figure 3 As shown, a retaining net device 6 is fixedly installed on one side of the reinforcing beam 4 close to the lattice beam 1. The retaining net device 6 specifically includes a plurality of vertical rods 61 uprightly connected to the reinforcing beam 4 and a retaining net 62 installed on the plurality of vertical rods 61. The retaining net 62 can be made of wire mesh, and the wire mesh and the vertical rods 61 are bound by wire. On rainy days, especially on heavy rain and rainstorms, rainwater flows on the top of the slope carrying dead branches and leaves, and the retaining net 62 intercepts the dead branches and leaves on the top of the slope, and provides nutrition for the plants on the top of the slope after the dead branches and leaves are decomposed. The traditional installation method of the retaining net 62 is to fix it on a fixed pile inserted in the soil at the top of the slope. After long-term use, the surface soil at the fixed pile will be lost, and the fixed pile has the hidden danger of being collapsed or washed away by rainwater. Once washed away, it will have an adverse effect on the plants on the slope surface and the bottom of the slope. In this case, the vertical rod 61 used to install the retaining net 62 is installed on the reinforcing beam 4 which is less affected by the impact of rainwater, instead of being inserted in the soil at the top of the slope. The entire retaining net device 6 has good stability, is not easy to collapse, and is not easy to be washed to the slope surface and the bottom of the slope by rainwater, and does not affect the plants on the slope surface and the bottom of the slope.
[0035] The bottom of the vertical rod 61 is provided with a connecting piece 63, and a plurality of connecting holes are provided on the connecting piece 63. The connecting hole is provided with a connecting component 64 connected to the reinforcing beam 4. The connecting component 64 can be a fastening bolt pre-buried in the reinforcing beam 4. After the fastening bolt passes through the connecting hole, it cooperates with the nut to fasten the connecting piece 63 to the surface of the reinforcing beam 4, thereby realizing the installation of the vertical rod 61. Of course, the connecting component 64 can also be an expansion screw to realize the installation of the vertical rod 61.
[0036] Embodiment 3, the prestressed anchor cable 3 is connected to the lattice beam 1 through a locking device 7, which is different from Embodiment 1 and Embodiment 2. Figure 4As shown in the figure, the locking device 7 includes a locking nut 71 and a cushion block assembly. The cushion block assembly includes a fixed cushion block 72 and a universal adjustment cushion block 73. The fixed cushion block 72 is connected to the lattice beam 1 through a plurality of connecting pieces 74. The connecting pieces 74 can be, but are not limited to, expansion screws. A spherical socket 721 with an upward opening is provided at the center of the fixed cushion block 72. The universal adjustment cushion block 73 has a spherical surface 731 that matches the shape of the spherical socket 721. Through the spherical surface 731 and the spherical socket 721, the universal adjustment cushion block 73 can achieve universal adjustment. The universal adjustment cushion block 73 also has a fitting plane 732 for fitting with the locking nut 71. The fixed cushion block 72, the universal adjustment cushion block 73, and the lattice beam 1 have a first cable duct 722, a second cable duct 733, and a third cable duct 11 for the first prestressed cable 3 to pass through. The first cable duct 722 runs downward from the bottom center of the spherical socket 721 to the bottom surface of the fixed cushion block 72. The second cable duct 733 runs upward from the bottom center of the spherical surface 731 to the fitting plane 732. An adjustment gap is formed between the second cable duct 733 and the first prestressed cable 3 to meet the adjustment requirements of the universal adjustment cushion block 73.
[0037] When the cable hole on the slope is offset, the universal adjustment cushion block 73 can be adjusted so that the fitting plane 732 on the universal adjustment cushion block 73 is parallel to the locking nut 71. At this time, when the locking nut 71 is tightened, the bottom of the locking nut 71 can be completely fitted on the fitting plane 732, that is, the two are in contact in a plane form, ensuring that the locking nut 71 has a large stress-bearing part and is not easily damaged, thus guaranteeing the reinforcement effect.
[0038] To ensure the long-term use effect, the outer end of the first prestressed cable 3 and the corresponding locking nut 71 are sealed by a concrete block to prevent the first prestressed cable 3, the locking nut 71, etc. from being exposed. The concrete block is not shown in the drawings.
[0039] The above embodiments only describe the preferred implementation manners of the present invention, and do not limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by those of ordinary skill in the art to the technical solutions of the present invention should fall within the protection scope of the present invention. The technical content claimed by the present invention has been fully recorded in the claims.
