Description

Technical Field

[0001] The present invention relates to the technical field, and in particular to a composite ecological landscape retaining wall and a construction method thereof. Background Art

[0002] Retaining walls generally refer to slope protection, which is a general term for various paving and planting on the slope surface to prevent the slope from being eroded. Since the concave bank of the river bank is eroded by water every year, it will cause the river bank to collapse continuously. In order to protect the safety of bridges and embankments, protective buildings must be built on the concave bank. In addition, when the construction of a bridge causes the flow of the river to change, eroding the river bank and endangering farmland and villages, protective buildings must also be built on the river bank.

[0003] Most of the existing slope protection is set up in sections. The section close to the river is set with concrete and stones for fixed protection, and the section away from the river is set with various green plants for greening and beauty. However, this makes the river water, concrete and green plants completely isolated, and the natural creation and artificial creation are separated without fusion effect, which makes the ecological landscape of the river poor and fails to improve the overall earthquake and impact resistance.

[0004] To this end, we propose a composite ecological landscape retaining wall and its construction method to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problems existing in the prior art and to propose a composite ecological landscape retaining wall and a construction method thereof.

[0013] Preferably, the isolation box is made of wooden material.

[0014] Preferably, a construction method of a composite ecological landscape retaining wall comprises the following steps:

[0015] S1. First, clear away the stones, weeds, and debris on the slope. When trimming the slope, clean it from top to bottom and make it as smooth as possible. For the slope, lay out the lines and set the grid according to the specified dimensions, and pull the wedges and piles along the horizontal and vertical directions of the slope to ensure that the construction slope is straight and beautiful.

[0016] S2. Then, a plurality of fixing pits are excavated on the slope, the excavated fixing pits are arranged at equal intervals, and the intervals between the plurality of fixing pits are 40-60 cm, and then a plurality of fixing frames are respectively inserted into the plurality of fixing pits, and concrete is poured into the fixing pits to fix the fixing frames;

[0017] S3. After the concrete in the fixing pit solidifies, the multiple reinforcing bars are respectively passed through the multiple fixing rings on the multiple fixing frames, so that the multiple reinforcing bars are in a criss-cross state, and steel wires are used to bind and fix the multiple reinforcing bars at the intersecting positions, and then multiple isolation boxes are placed in the gaps between the multiple reinforcing bars, and then concrete is filled in the areas on the reinforcing bars and outside the multiple isolation boxes to form a concrete layer with holes to protect the slope;

[0018] S4. Dig an anchoring ditch 40-50cm deep and 50cm-70cm wide at 50cm on one side of the flat slope close to the slope. The anchoring ditch is set in a U shape. Then, lay the mesh on the slope. One end of the mesh is laid in the anchoring ditch, and the mesh is fixed in the anchoring ditch by inserting the anchor pile into the pile pit. The anchor pile is provided with a plurality of spikes, which can be inserted into the soil layer of the flat slope to form a support surface, increase the lateral area, avoid the flow slope phenomenon, and improve the firmness and stability of the mesh. At the same time, on the side of the mesh close to the embankment, an anchor bar is inserted into the fastening pit to fix the edge of the mesh.

[0019] S5. When the anchor piles are fixed and installed, the user can pull the locking rod on the grid piece, clamp the open end of the locking rod on the fixed shaft, and then fix the locking rod and the fixed shaft with screws, so that the locking rods form a V shape in the grid piece through multiple locking rods, and abut against the inner wall of the U-shaped grid piece to form a support structure, thereby improving the overall earthquake resistance and impact resistance of the flat slope. Then, backfilling work can be carried out on the slope and the flat slope. When carrying out the burying work, the flat slope part is filled with soil first, and after the top anchor trench is buried, the soil is filled from top to bottom until the multiple isolation boxes on the slope are buried. After the height of the grid piece is buried, it is necessary to increase the thickness of the buried grid piece by one-third of the height. After the backfill is manually raked and leveled, the compaction work is completed by a machine to prevent displacement.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention effectively protects the slope by setting up structures such as a concrete layer and a fixing frame, so that the slope will not easily collapse due to erosion by river water flow, and at the same time, with the help of the reserved isolation box and the corresponding openings, flowers and plants can be planted smoothly, and then enough plants can grow on the slope, which can further tighten the water and soil and make the slope more ecological and beautiful.

[0032] A construction method for a composite ecological landscape retaining wall comprises the following steps:

[0033] S1. First, clean up the stones, weeds, and debris on the slope 1. When trimming the slope 1, it is necessary to clean the slope from top to bottom and make it as smooth as possible. For the slope 1, lay out the lines and fix the grids according to the specified dimensions, and respectively wedge and pull the lines along the horizontal and vertical directions of the slope 1 to ensure that the construction slope is straight and beautiful in appearance;

[0034] S2. Then, a plurality of fixing pits 4 are excavated on the slope 1. The excavated fixing pits 4 are arranged at equal intervals, and the interval between the plurality of fixing pits 4 is 40 cm. Then, a plurality of fixing frames 5 are respectively inserted into the plurality of fixing pits 4, and concrete is poured into the fixing pits 4 to fix the fixing frames 5. In this way, the fixing effect of the fixing frames 5 on the slope 1 can be better, and then the protective effect of the concrete layer 9 can be better.

[0035] S3. After the concrete in the fixing pit 4 is solidified, the multiple reinforcing ribs 7 are respectively passed through the multiple fixing rings 6 on the multiple fixing frames 5, so that the multiple reinforcing ribs 7 are in a criss-cross state, and at the same time, the multiple reinforcing ribs 7 are tied and fixed at the staggered positions with steel wires, and then the multiple isolation boxes 8 are placed in the gaps between the multiple reinforcing ribs 7, and then the area on the reinforcing ribs 7 and outside the multiple isolation boxes 8 is filled with concrete to form a concrete layer 9 with holes to protect the slope 1. In this way, the slope 1 can be better protected by the concrete layer 9, so that the slope 1 will not collapse due to river erosion, ensuring the safety of the river bank. At the same time, the reserved openings allow green plants to be planted and grown smoothly, and then the concrete layer 9 can be well integrated with the green plants, thereby forming an excellent ecological landscape;

[0036] S4. At 50 cm on one side of the flat slope 3 close to the slope 1, dig an anchoring trench 11 with a depth of 40-50 cm and a width of 50 cm-70 cm. The anchoring trench 11 is set in a U shape. Then, lay the mesh 10 on the slope 1. One end of the mesh 10 is laid in the anchoring trench 11, and the mesh 10 is fixed in the anchoring trench 11 by inserting the anchor pile 13 into the pile pit 12. The anchor pile 13 is provided with a plurality of spikes 1303. The spikes 1303 can be inserted into the soil layer of the flat slope 3 to form a supporting surface, increase the lateral area, avoid the flow slope phenomenon, and improve the firmness and stability of the mesh 10. At the same time, on the side of the mesh 10 close to the embankment 2, the anchor bar 15 is inserted into the fastening pit 14 to fix the edge of the mesh 10, so that the soil layer 16 laid subsequently can be fixed with the help of the mesh 10;

[0037] S5. After the anchor pile 13 is fixed and installed, the user can pull the locking rod 1003 on the grid member 10, clamp the open end of the locking rod 1003 on the fixed shaft 1305, and then fix the locking rod 1003 and the fixed shaft 1305 with screws, so that a V shape is formed in the grid member 10 through multiple locking rods 1003, which abut against the inner wall of the U-shaped grid member 10 to form a support structure, thereby improving the overall earthquake resistance and impact resistance of the flat slope 3, and then fill the slope 1 and the flat slope 3. During the burying work, the flat slope 3 is first filled with soil, and after the top anchoring ditch 11 is buried, the multiple isolation boxes 8 on the slope 1 are filled with soil from top to bottom. After the height of the grid 10 is buried, the thickness of the buried grid 10 is increased by one third of the height. After the fill is manually raked and leveled, a machine is used to complete the compaction work to prevent displacement, so that the soil layer 16 can be laid more stably on the slope 1, thereby making the slope 1 more beautiful.
