Description

TECHNICAL FIELD

[0001] The present application relates to the field of gravity retaining wall, in particular to the safety gravity retaining wall and its working method. BACKGROUND

[0002] Gravity retaining wall is a kind of retaining structure widely used in railway, highway embankment and cutting, tunnel portal, bridge, water conservancy and building slope engineering, which mainly relies on the self weight of the wall to resist the lateral pressure of the soil behind the wall to maintain the stability of the retaining wall under the earth pressure, and is a commonly used retaining wall in China. Gravity retaining wall is generally made of mortar rubble concrete or concrete integral pouring;

[0003] In order to solve the greening problem, some gravity retaining walls are provided with outward protruding green grooves on the wall body, but the outward protruding green grooves will increase the self weight of the gravity retaining wall after filling with planting soil and planting plants, thereby increasing the overturning moment of the gravity retaining wall and increasing the overturning risk. Some gravity retaining walls are composed of a plurality of sectional prefabricated hollow blocks, and green plants are planted in the hollow structure of the block to realize the functions of retaining and greening. Although this kind of gravity retaining wall can also realize the function of greening, the structure of the retaining wall is composed of hollow blocks, the wall body has poor longitudinal and horizontal integrity, the terrain adaptability is poor, and under the action of rain for a long time, the planting soil in the block is easy to lose, which will also lead to the difficulty in ensuring the long-term stability of the retaining wall. SUMMARY

[0007] The left and right sides of the opening are respectively provided with a pouring hole, and the pouring hole is inclinedly penetrated through the inner and outer sides of the wall body.

[0008] A preferred technical solution: the green groove comprises a shaped frame body, a fixed plate and a bolt, the shaped frame body is Y-shaped, a support body is arranged in the opening, the shaped frame body penetrates through the opening, the lower part of the shaped frame body is arranged on the surface of the support body, and the fixed plate is respectively arranged on the surface of the shaped frame body and the support body, and the bolt is fixed with the shaped frame body after penetrating through the fixed plate.

[0009] A preferred technical solution: the outer side of the support body has an outwardly protruding step edge on both the upper and lower parts, and the thickness of the upper step edge on the outer side of the support body is higher than the thickness of the other step edge;

[0010] The lower right surface of the forming frame has a first groove. When the forming frame is installed into the opening, the upper outer step of the support body is embedded in the first groove along its surface, and the lower right surface of the forming frame is flush with the lower outer surface of the support body.

[0011] A preferred technical solution: The lower right surface of the forming frame has a second groove, and the lower surface of the fixing plate has a corresponding protrusion. When the fixing plate abuts against the surface of the forming frame, the protrusion is embedded in the second groove, and the outer surface of the fixing plate is flush with the surface of the wall body.

[0012] A preferred technical solution: The upper part of the fixing plate has a bent surface, which abuts against the upper right surface of the forming frame. The bent surface of the fixing plate has multiple positioning protrusions, and the upper right surface of the forming frame has multiple corresponding slots. When the fixing plate abuts against the surface of the forming frame, the positioning protrusions are embedded in the slots.

[0013] A preferred technical solution: The left side surface of the forming frame is provided with a deformation abutment and a baffle, the deformation abutment is placed on the wall body, the baffle is placed outside the wall body, and the deformation abutment and the baffle are respectively abutted on the inner and outer sides of the wall body.

[0014] A preferred technical solution: the right side of the deformable abutment is unfolded separately from the forming frame, and the right side of the deformable abutment is bent and abuts against the surface of the wall body.

[0015] A preferred technical solution: The baffles are symmetrically arranged at the two ends of the forming frame, and each of the two baffles has a notch for drainage at the bottom.

[0016] A method for operating the gravity retaining wall, the method comprising the following specific steps:

[0017] S1: Fix the wall body to the slope by pouring or building, and reserve the support and injection hole on the surface of the support. Then insert the greening trough and pass through the opening. Apply external force to set the formed frame against the surface of the support.

[0018] S2: Install the fixing plate on the surface of the forming frame and fix it with bolts to make the forming frame and the fixing plate an integrated unit;

[0022] This invention enhances the consolidation effect by setting up green troughs, planting plants, and solving problems such as soil erosion, easy collapse, and poor environmental adaptability as described in the background art. Because when the green trough passes through the opening, a part of its surface forms an angle with the inner side of the wall body, allowing this part of the green trough's surface to obtain a strong support effect by embedding into the slope and fixing it to the wall body. This effectively avoids problems such as displacement, collapse, and soil erosion. Furthermore, through the design of the first and second grooves, fixation is achieved. When the forming frame is pushed or squeezed, it can bear the force together with the entire wall body. The upper bent part of the fixing plate abuts against the forming frame to form a pressure bar, preventing the forming frame from collapsing due to prolonged stress. Attached Figure Description

[0028] In the diagram: wall body 1, support body 11, grouting hole 12, greening trough 2, forming frame 21, deformation abutment part 211, baffle 212, first groove 213, second groove 214, fixing plate 22, positioning protrusion 221, bolt 23. Detailed Implementation

[0029] like Figures 1-5As shown, the safety-grade gravity retaining wall includes a wall body 1 and a greening trough 2. The wall body 1 has an opening for installing the greening trough 2, which rests against the surface of the support body 11 and passes through the opening. A filling hole 12 is provided on each of the left and right sides of the opening, and the filling hole 12 is inclined and passes through the inner and outer sides of the wall body 1. The purpose and significance of setting the filling hole 12 is that when the greening trough 2 is installed, any material such as prepared cement, adhesive, or filler can be discharged into the gap between the wall body 1 and the slope through the filling hole 12 via a feed hopper or connecting pipe. Both the upper and lower ends of body 1 are provided with a bend in the same direction. The upper bend is placed on the upper surface of the slope, while the lower bend is inserted into the slope from the outside to form a wall reinforcement effect. The purpose of the greening trough 2 is to further enhance the reinforcement effect, plant vegetation, and solve the problems of soil erosion, easy collapse, and poor environmental adaptability as mentioned in the background art. Because when the greening trough 2 passes through the opening, a part of its surface forms an angle with the inner side of the wall body 1, so that this part of the surface of the greening trough 2 can obtain a strong support effect by embedding into the slope and fixing it to the wall body 1, which can effectively avoid the problems of displacement, collapse, and soil erosion.

[0030] Furthermore, the greening trough 2 includes a forming frame 21, a fixing plate 22, and bolts 23. The forming frame 21 is Y-shaped, and a support body 11 is provided in the opening. The forming frame 21 passes through the opening, and the lower part of the forming frame 21 abuts against the surface of the support body 11. The fixing plate 22 is respectively covered on the surfaces of the forming frame 21 and the support body 11. The bolts 23 pass through the fixing plate 22 and are fixed to the forming frame 21. This arrangement is to improve the firmness of the forming frame 21, increase the support force of the forming frame 21 on the soil and plants, and improve the water and soil retention capacity. Because when the forming frame 21 is installed on the surface of the support body 11 in the opening, it is also fixed by the fixing plate 22. When the forming frame 21 is moved, the fixing plate 22 pries the wall body 1 as a whole, thus forming a stable and balanced force.

[0031] Furthermore, the support body 11 has an outwardly protruding stepped edge on both the upper and lower outer sides, and the thickness of the upper stepped edge on the outer side of the support body 11 is greater than the thickness of the other stepped edge; while the lower right surface of the forming frame 21 has a first groove 213. When the forming frame 21 is installed into the opening, the upper stepped edge surface of the outer side of the support body 11 is embedded in the first groove 213, and the lower right surface of the forming frame 21 is flush with the lower outer surface of the support body 11. When the forming frame 21 and the fixing plate 22 are installed based on this design, the adjacent surfaces of the forming frame 21 and the fixing plate 22 can be tightly fitted, and under the locking effect of the bolts 23, they form an integrated structure with the wall body 1. In the event of a collapse or landslide, In situations such as collapse or movement of the slope, the wall body 1 can act as a barrier, and the bending part at the lower edge of the wall body 1 creates friction with the bottom of the slope. The lower right surface of the forming frame 21 has a second groove 214, and the lower surface of the fixing plate 22 has a corresponding protrusion. When the fixing plate 22 abuts against the surface of the forming frame 21, the protrusion is embedded in the second groove 214, and the outer surface of the fixing plate 22 is flush with the surface of the wall body 1. With this design, when the slope inside the wall body 1 collapses or moves, it will squeeze the left side of the forming frame 21. The forming frame 21 will drive the fixing plate 22 and the wall body 1 as a whole to bear the force, preventing the greening trough 2 from moving, deforming or collapsing.

[0032] Furthermore, the upper part of the fixing plate 22 has a bent surface, which abuts against the upper right surface of the forming frame 21. The bent surface of the fixing plate 22 has multiple positioning protrusions 221, and the upper right surface of the forming frame 21 has multiple corresponding slots. When the fixing plate 22 abuts against the surface of the forming frame 21, the positioning protrusions 221 are embedded in the slots. The purpose of setting the positioning protrusions 221 is to facilitate the positioning effect when the fixing plate 22 is installed, so that the bolt 23 can be accurately embedded into the forming frame 21 when it is rotated and inserted, thus forming a positioning effect. Moreover, the bent surface of the upper part of the fixing plate 22 can pull and support the upper right surface of the forming frame 21, that is, the fixing plate 22 provides support for the forming frame 21.

[0033] Furthermore, the left side surface of the forming frame 21 is provided with a deformation abutment 211 and a baffle 212, respectively. The deformation abutment 211 is placed on the wall body 1, and the baffle 212 is placed outside the wall body 1. The deformation abutment 211 and the baffle 212 abut against the inner and outer surfaces of the wall body 1, respectively. The right side of the deformation abutment 211 is separated from the forming frame 21 and extends outward, while the right side of the deformation abutment 211 is curved and abuts against the wall body 1. When the forming frame 21 is squeezed or moved outward by the sliding soil, the surface of the wall body 1 can be pressed against the inner side of the wall body 1 by the deformation abutment 211 to prevent the forming frame 21 from moving. The deformation abutment 211 is made of rubber. When 213 is pressed against the surface of the support 11, the deformation abutment 211 is also pressed against the inner side of the wall body 1. As the fixing plate 22 is locked and installed, the force applied to the deformation abutment 211 is increased.

[0034] Furthermore, the baffles 212 are symmetrically arranged at both ends of the forming frame 21, and each of the two baffles 212 has a drainage notch at the bottom. The notch is designed to drain excess water and prevent the planted plants from being submerged and dying during heavy rainfall. During light rainfall, the water will be directly absorbed by the soil and plants and will not drain out through the notch. With this design, there is no need to worry about soil loss because the roots and stems of the plants will absorb and fix a large amount of soil.

[0035] A method for operating the gravity retaining wall, the method comprising the following specific steps:

[0036] S1: The wall body 1 is fixed on the slope by pouring or building, and the support body 11 and the injection hole 12 are reserved on the surface of the support body 11. The greening trough 2 is inserted and passes through the opening. The forming frame 21 is pressed against the surface of the support body 11 by applying external force.

[0037] S2: Install the fixing plate 22 on the surface of the molding frame 21 and fix it with bolts 23, so that the molding frame 21 and the fixing plate 22 are integrated;

[0038] S3: Cement is discharged into the space between the wall body 1 and the slope through the external connecting pipe or funnel of the grouting hole 12, filling the gap and playing an adhesive role.

[0039] S4: Pour soil onto the upper surface of the forming frame 21 and use baffles 212 to cover the soil. Plants are planted using this soil, which prevents tipping over and retains moisture.

All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification should still fall within the scope of the present invention.
