Description

TECHNICAL FIELD

[0002] A building slope refers to a regular-shaped slope formed by artificial excavation according to a certain slope and shape on a building site or its periphery. In recent years, with the gradual acceleration of urbanization, the demand for urban buildings has also grown rapidly, leading to the continuous increase in the scale of urban building and civil construction.

[0003] High-strength and large-scale urban land resource development not only ensures the rapid development of cities, but also has many negative impacts on the ecological environment, such as vegetation degradation, soil erosion, and induced geological disasters. Unrepaired building slopes or road and bridge slopes not only affect the normal use of buildings, roads and bridges to some extent, but also affect the surrounding ecological conditions.

[0004] The traditional treatment and repair method is to build multiple anti-slide piles on the slope. During construction, multiple row-distributed foundation pits are first opened at the slope, then steel cages are installed in the foundation pits, and finally concrete is poured to form anti-slide piles, which have a supporting effect on the rock mass at the slope, improve the stability of the slope, and reduce the possibility of collapse. The use of chemical agents such as solidifying agents for concrete pouring can easily affect the surrounding original ecology. Anti-slide piles and anchor rods have requirements for the geological conditions of the slope, and if the geological conditions of the slope are loose, the anti-slide piles and anchor rods are not fixed enough.

[0059] The bottom upper side (close to the top side of the slope 1) and the bottom lower side (close to the bottom side of the slope 1) of the protective plate 4 are provided with cable connecting ear plates, which are respectively used for connecting the first protective fixed cable 7 and the second protective fixed cable 9; the cable connecting ear plate and the protective plate 4 are integrally formed to ensure the connection strength.

[0060] In this embodiment, in combination with Figure 2 andFigure 3 As shown, the cable restraint assembly includes a first protective fixed cable 7, a second protective fixed cable 9, and a cable fixing mechanism 8; the first protective fixed cable 7 and the second protective fixed cable 9 are both galvanized steel strands, with high strength and corrosion resistance.

[0062] As shown in Figure 3 The guide rod 803 is a circular metal rod, with one end fixedly connected to the bearing base plate 801 perpendicularly, and the other end inserted into the guide pipe 804 pre-buried in the soil of the slope 1; the guide pipe 804 is a galvanized steel pipe, for limiting the movement direction of the guide rod 803, ensuring the smooth movement of the bearing base plate 801 in the preset direction.

[0066] Embodiment 2

[0067] The embodiment provides a slope protection method applied to the slope protection device for excavating, repairing, and preventing collapse, and the method comprises the following steps:

[0068] Fixing rod installation (S1)

[0069] First, the soil at the top and bottom of the slope 1 is pretreated: the surface floating soil and gravel are removed to ensure that the installation surface is flat; for the loose soil area, a layer of graded gravel with a thickness of 100-150 mm can be laid to enhance the bearing capacity of the soil.

[0070] For the vertical fixing rod 2: the first limiting sheet 11 is rotatably accommodated in the rod body through a pin shaft, the vertical fixing rod 2 is vertically inserted into the ground from the top of the slope 1 by using a pile driver, and the insertion depth is determined according to the thickness of the soil; after the insertion is completed, the pry bar is inserted through the hole at the top of the rod body, the first limiting sheet 11 is rotated around the pin shaft to the outside of the rod body, and is embedded into the surrounding soil to complete the anchoring of the vertical fixing rod 2.

[0071] For the horizontal fixing rod 3: the second limiting sheet 12 is accommodated in the rod body, and the horizontal fixing rod 3 is horizontally inserted into the ground from the bottom of the slope 1 by using a horizontal directional drill or a pile driver; after the insertion is completed, the second limiting sheet 12 is rotated to the outside of the rod body through the hole at the end of the rod body, and is embedded into the surrounding soil to complete the anchoring of the horizontal fixing rod 3.

[0072] Lead rod assembly (S2)

[0073] The horizontal lead rod 5 is connected with the vertical fixed rod 2, and the axis of the horizontal lead rod 5 is perpendicular to the axis of the vertical fixed rod 2. The vertical lead rod 6 is connected with the outer end of the horizontal fixed rod 3, and the axis of the vertical lead rod 6 is perpendicular to the axis of the horizontal fixed rod 3; meanwhile, the position of the vertical lead rod 6 is adjusted so that the vertical lead rod 6 can smoothly pass through the first through hole 501 on the horizontal lead rod 5, and the second through hole 601 on the vertical lead rod 6 is located inside the horizontal lead rod 5. Specifically, the vertical fixed rod 2 is pre-fabricated with a hole for inserting and connecting the horizontal lead rod 5, and the horizontal fixed rod 3 is pre-fabricated with a hole for inserting and connecting the vertical lead rod 6, and both the insertion and connection can be reinforced and fixed by using a threaded pair. Before installation, holes are drilled in the slope 1, the vertical fixed rod 2 and the horizontal fixed rod 3 are inserted into the holes, then the horizontal lead rod 5 is inserted into the corresponding hole, and the horizontal lead rod 5 is tightened by aligning the hole of the vertical fixed rod 2. Finally, the vertical lead rod 6 is inserted into the corresponding hole, and the vertical lead rod 6 passes through the first through hole 501 during the insertion process, and the bottom end is aligned with the hole of the horizontal fixed rod 3 and is tightened.

[0074] Laying the protective plate 4 (S3)

[0075] The protective plate 4 is laid layer by layer from the bottom to the top of the slope 1, and then the adjacent protective plates 4 are spliced and fixed by using buckles or bolts to form an overall protection unit. If the soil body of the slope 1 is loose, after the laying of the protective plate 4 is completed, metal anchor rods are inserted through the anchor rod holes in the corners of the protective plate 4, and the anchor rods are driven into the ground of the slope surface by using an impact drill, and the insertion depth is not less than 200 mm, so as to ensure that the protective plate 4 is tightly attached to the slope surface. Nutrient soil is filled in the planting groove in the center of the protective plate 4 as needed, and drought-resistant and soil-fixing green plants (such as alfalfa) are planted, and the planting density is 3-5 plants per planting groove. After completion, watering and curing are performed to promote the survival of the green plants.

[0076] Cable connection (S4)

[0077] The first protective fixed cable 7 and the second protective fixed cable 9 are operated by using an elongated rod (end part with a clamp). First, the clamp clamps the first protective fixed cable 7, the elongated rod is inserted into the vertical lead rod 6, and another elongated rod (end part with a hook) is prepared to be inserted into the horizontal fixed rod 3. The elongated rod in the horizontal fixed rod 3 hooks the safety buckle or the round loop knot at the end part of the first protective fixed cable 7 lowered from the vertical lead rod 6, the elongated rod in the horizontal fixed rod 3 pulls the first protective fixed cable 7 around the winding turning wheel 10 and outward, and finally the first protective fixed cable 7 extends to the cable fixing mechanism 8 at the bottom of the slope 1, and the cable end part is fixed in the cable fixing hole of the bearing base plate 801 by a bolt. Similarly, the second protective fixed cable 9 also uses an elongated rod to sequentially pass through the horizontal lead rod 5 and the winding turning wheel 10 in the vertical fixed rod 2, and finally extends to the cable fixing mechanism 8 at the top of the slope 1, and the cable end part is fixed in the cable fixing hole of the bearing base plate 801 by a bolt. It should be noted that the cable connection process can be assisted by an endoscope for more convenient operation.

[0078] Cable tightening (S5)

[0079] The reverse thrust 802 is started to push the bearing base plate 801 to move along the guide rod 803 in the direction away from the slope 1, at this time, the first protective fixed cable 7 and the second protective fixed cable 9 are gradually tightened; at the same time, the tension of the cable is monitored by using a tension meter, and when the tension reaches a preset value, the rotation of the reverse thrust 802 is stopped. The first protective fixed cable 7 and the second protective fixed cable 9 exert a force on the protective plate 4 towards the ground and perpendicular to the slope surface of the slope 1, to ensure the stability of the protective plate 4. Brick is inserted between the bearing base plate 801 and the soil of the slope 1, and the number of bricks is determined according to the gap between the bearing base plate 801 and the soil (to ensure that the bricks are tightly packed without looseness); after the brick filling is completed, the reverse thrust 802 is removed, at this time, the brick supports the bearing base plate 801 to maintain the stability of the tension of the cable. Concrete can also be filled between the bearing base plate 801 and the soil of the slope 1 to enhance the fixation.

[0080] Protection and maintenance (S6)

[0081] Periodic inspection of device status: including whether the protective plate 4 is cracked or displaced, whether the cable is loose or broken, whether the green plants are alive, etc.

[0082] The above specific embodiments further illustrate the purpose, technical solutions and advantages of the present application.
