Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy projects, in particular to a flexible retaining wall. Background Art

[0002] Retaining wall technology is widely used in geotechnical engineering soil support and water conservancy engineering embankment protection. There are many different structural forms of retaining walls, among which the main and commonly used structural forms are gravity retaining walls and arm retaining walls. However, the retaining walls under the current technology occupy a large area, and it is not easy for groundwater and surface water to penetrate, which is not conducive to the growth of plants in the entire river channel. Grass does not grow, and there is no growth space for water plants, and there are no animals accordingly, which is not ecological; the current gravity retaining walls and arm retaining walls have a slope fill surface. Under the pressure of the soil, two forces will be generated on the retaining wall. One force is sliding displacement, which is easy to push the retaining wall away, and the other force is tilting rotation, which has poor anti-tilting ability, is not strong enough, has poor strength, and is prone to landslides, posing a greater hidden danger. Gabion retaining wall is an ecological protection structure, and its basic operating unit is a stone-filled mesh box. Plants can grow in the stone-filled space in the stone cage, and can also achieve beautification by pre-embedded vine branches, etc., and be in harmony with nature. Compared with other retaining structures, gabion retaining walls have obvious advantages: excellent drainage, regular and beautiful slopes; flexible structure, good ground adhesion, low bearing capacity requirements; good durability, high galvanized corrosion resistance; mechanical weaving into a net, flexible production, convenient transportation and storage, no need for very regular stones, and can be adapted to local conditions. Gabion retaining walls have been widely used and have become an important component of ecological projects at home and abroad. The existing gabion retaining walls are made by independently manufacturing multiple cubic grids. The cubic grids require that each grid piece be connected with metal wires to form a cubic structure, and then stones are placed to form a single three-dimensional gabion retaining wall block. The single three-dimensional gabion retaining wall blocks are staggered and connected to form a retaining wall, in which the structural integration is poor, the manufacturing process is poor, and it cannot be anchored to the ground to improve its stability. In order to solve the above technical problems, the present application document provides a flexible retaining wall. Utility Model Content

Specific embodiment one:

[0025] See also Figure 1-7As shown, the utility model is a flexible retaining wall, comprising a plurality of column support units, a flexible isolation net 5 connecting the column support units, and stones filled in the grid surrounded by the flexible isolation net 5. The column support unit comprises a plurality of section support columns 1 connected continuously end to end, a clamping plate 2 and an anchoring plate 3 respectively installed on the support columns 1 by bolts, and a cone head 4 installed at the lower end of the lowest support column 1. The support column 1 specifically comprises a quadrangular prism 11. A circular arc groove 12 arranged along the axial direction is respectively provided at the four edges of the quadrangular prism 11. A row of first threaded holes 13 is provided at the bottom of the circular arc groove 12. A threaded blind hole 14 is provided at the upper end of the quadrangular prism 11. A threaded joint 15 matching the threaded blind hole 14 is fixed at the lower end of the quadrangular prism 11. The support columns 1 can be quickly extended and connected with each other, which is suitable for anchoring at different depths and stacking of stones at different heights. In addition, a flexible isolation net 5 is laid flat on the top and connected to the vertically arranged flexible isolation net 5 by using metal wires to protect the stones inside.

[0026] The utility model forms a column support unit through supporting columns 1, clamping plates 2, anchor plates 3 and cone heads 4, which is stably installed on the ground soil layer. The column support units are distributed in a grid, and flexible isolation nets 5 are quickly installed between the column support units to form a retaining frame connected as a whole in a grid. Stones are filled in the frame to form a grid retaining wall that is stably connected as a whole. The overall structure is strengthened and the laying of the flexible isolation net 5 is simplified.

[0027] The anchor plate 3 is specifically a rectangular plate structure, and the side of the anchor plate 3 facing the arc groove 12 is set as an arc surface. A plurality of second threaded through holes 31 for inserting bolts are provided on the anchor plate 3. A plurality of fan-shaped plates 32 arranged to be inclined upward are evenly fixed on the side of the anchor plate 3 away from the arc groove 12. The required anchoring depth is determined according to the looseness of the soil layer of the slope protection, and then the number of nodes of the combination of the support column 1 and the anchor plate 3 is adjusted. The cone head 4 at the lower end helps to remove hard objects such as stones in the soil layer, making it easier for the support column 1 to enter the soil layer. After the anchor plate 3 enters the soil layer, the fan-shaped plate 32 on it is expanded with a larger upper portion and a smaller lower portion, which helps to stabilize the state in the soil layer and has a good anchoring effect.

[0028] The clamping plate 2 is specifically a rectangular plate structure, and the side of the clamping plate 2 facing the arc groove 12 is set as an arc surface. The clamping plate 2 is provided with a plurality of first threaded through holes 21 for inserting bolts. After the column support unit is installed and positioned on the slope, the flexible isolation net 5 is vertically arranged on the outside of the support column 1, the clamping plate 2 is taken to press the flexible isolation net 5 into the arc groove 12, and then the clamping plate 2 is pre-tightened with bolts. The pre-tightened clamping plate 2 stably fixes the flexible isolation net 5 on the support column 1. The flexible isolation net 5 between two adjacent support columns 1 is pre-tightened and straightened.

[0029] The flexible isolation net 5 is a geogrid or a steel wire mesh, both of which have good water-passing capacity and are conducive to rapid drainage.
