Description

Technical Field

[0001] The utility model relates to the technical field of retaining walls, and specifically relates to a retaining wall. Background Art

[0002] A retaining wall is an engineering structure used to prevent water flow erosion and resist water pressure. It is mainly used in water conservancy projects or water diversion projects such as rivers, reservoirs, canals, and embankments, thereby playing a role in controlling water flow, protecting the bank slope, and reducing the risk of flood disasters. Without the protection of the retaining wall, the surrounding soil mass will collapse into the channel under the action of gravity, affecting the normal water conveyance function of the channel.

[0003] In the existing patent literature, a patent with a publication number of CN 221567103 U and a name of "Hydraulic Retaining Wall" has an installation mechanism that is entirely exposed outside the installation hole. This installation mechanism is soaked and scoured in water for a long time, and it is easily eroded by water, resulting in a significant reduction in the service life of the installation mechanism. Moreover, the exposed installation mechanism also affects the aesthetics of the retaining wall. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a retaining wall. When installing this retaining wall, a fixed positioning pile is first poured into the positioning hole, and then the positioning hole and the wall joint can be completely covered by the side strengthening ribs, avoiding water intrusion from the positioning hole and eroding the positioning pile, greatly extending the service life of the positioning pile, and making the entire precast concrete wall more beautiful.

[0005] To solve the above technical problems, the technical solution of the utility model is realized as follows:

[0006] A retaining wall includes a precast concrete wall body. The precast concrete wall body includes an inclined part and a horizontal part. A plurality of uniformly distributed positioning holes are penetrated through the walls of both the inclined part and the horizontal part. A positioning pile that is cast and fixed in the foundation is installed in each positioning hole;

[0007] A plurality of side strengthening ribs are also inserted on one side of the precast concrete wall body; Two groups of wedge-shaped slide rails are cast and fixed on the side of the side strengthening rib facing the precast concrete wall body. Wedge-shaped chutes that are matched with the wedge-shaped slide rails are cast and fixed on the side surface of the inclined part of the precast concrete wall body. The wedge-shaped chutes are distributed beside the positioning holes and beside the wall edge;

[0008] When the side strengthening rib is installed on the wedge-shaped chutes beside the positioning holes through the wedge-shaped slide rails, at this time, the side strengthening rib can cover all the positioning holes on the same vertical plane; when the side strengthening rib is installed on the wedge-shaped chutes beside the wall edge through the wedge-shaped slide rails, at this time, the side strengthening rib can cover the wall joint between two adjacent precast concrete wall bodies.

[0009] With the above solution, when installing the retaining wall, the positioning pile is first poured into the positioning hole, and then the side strengthening ribs can completely cover the positioning hole and the wall joint, preventing water from invading through the positioning hole and eroding the positioning pile, greatly extending the service life of the positioning pile, and making the entire precast concrete wall more beautiful.

[0010] As a preferred implementation of the retaining wall, the side strengthening ribs include a first side strengthening rib and a second side strengthening rib. The first side strengthening rib is used to cover the positioning hole, and the second side strengthening rib is used to cover the wall joint; the width of the first side strengthening rib is greater than the width of the second side strengthening rib.

[0011] With the above solution, to ensure that the first side strengthening rib can cover the positioning hole and the second side strengthening rib can cover the wall joint, since the diameter of the positioning hole is much larger than the gap of the wall joint, the width of the first side strengthening rib is designed to be larger, so as to meet the covering of the positioning hole by the first side strengthening rib.

[0012] As a preferred implementation of the retaining wall, a reinforcing bar welded to the wedge-shaped slide rail is also poured and fixed inside the first side strengthening rib and the second side strengthening rib; the reinforcing bar and the wedge-shaped slide rail are perpendicularly welded and fixed.

[0013] With the above solution, to further improve the fixing effect of the wedge-shaped slide rail inside the side strengthening rib, the wedge-shaped slide rail is further strengthened by adding a reinforcing bar, so as to ensure the stability and reliability of the pouring and fixing of the wedge-shaped slide rail.

[0014] As a preferred implementation of the retaining wall, the bottom end of the positioning pile is a pointed end; multiple horizontally arranged annular grooves and vertically arranged linear grooves are provided on the side wall of the positioning pile, and the annular grooves and the linear grooves are alternately distributed; a hollow cavity is provided inside the positioning pile, and through holes communicating with the hollow cavity are provided at the intersections between the annular grooves and the linear grooves.

[0015] With the above solution, to improve the pouring and fixing effect of the positioning pile in the positioning hole, since multiple annular grooves and linear grooves are provided on the side wall of the positioning pile, during pouring, the contact surface between the concrete and the positioning hole and the positioning pile can be increased, and the fixing effect after pouring will be better; secondly, the concrete can enter from the hollow cavity and then flow to all the annular grooves and linear grooves through the through holes, making the pouring of the concrete more uniform.

[0016] As a preferred implementation of the retaining wall, a positioning ring is also poured and fixed in each positioning hole, and the positioning pile is vertically sleeved in the positioning ring in the positioning hole.

[0017] With the above solution, to assist in the fixing of the positioning pile in the positioning hole, a positioning ring is preset in the positioning hole, and when pouring the positioning pile, the positioning pile is sleeved in the positioning hole, which is convenient for subsequent pouring of the positioning pile.

[0018] After adopting the above technical solution, the beneficial effects of the present utility model are as follows:

[0019] 1. When installing this retaining wall, first pour and fix the positioning pile into the positioning hole, and then the side strengthening ribs can completely cover the positioning hole and the wall joint, preventing water from invading through the positioning hole and eroding the positioning pile, greatly extending the service life of the positioning pile, and making the entire precast concrete wall more beautiful;

[0020] 2. To ensure that the first side strengthening rib can cover the positioning hole and the second side strengthening rib can cover the wall joint, since the aperture of the positioning hole is much larger than the gap of the wall joint, the width of the first side strengthening rib is designed to be larger to meet the covering of the positioning hole by the first side strengthening rib;

[0021] 3. To further improve the fixing effect of the wedge-shaped slide rail in the side strengthening rib, the wedge-shaped slide rail is further strengthened by adding reinforcing ribs to ensure the stability and reliability of the pouring and fixing of the wedge-shaped slide rail;

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0038] As shown in Figures 1 to 7As shown in the figure, a retaining wall is used on both sides of the channel of the water diversion project. It includes a precast concrete wall body 1. The precast concrete wall body 1 includes an inclined part and a horizontal part. A plurality of uniformly distributed positioning holes 2 are penetrated through the walls of the inclined part and the horizontal part. A positioning pile 3 that is cast and fixed in the foundation is installed in each positioning hole 2; A plurality of side strengthening ribs 4 are also inserted on one side of the precast concrete wall body 1; Two groups of wedge-shaped slide rails 5 are cast and fixed on the side of the side strengthening rib 4 facing the precast concrete wall body 1. A wedge-shaped chute 6 that cooperates with the wedge-shaped slide rail 5 is cast and fixed on the side surface of the inclined part of the precast concrete wall body 1. The wedge-shaped chutes 6 are distributed beside the positioning holes 2 and beside the wall edge; When the side strengthening rib 4 is installed in the wedge-shaped chute 6 beside the positioning hole 2 through the wedge-shaped slide rail 5, at this time, the side strengthening rib 4 can cover all the positioning holes 2 on the same vertical plane; When the side strengthening rib 4 is installed in the wedge-shaped chute 6 beside the wall edge through the wedge-shaped slide rail 5, at this time, the side strengthening rib 4 can cover the wall joint between two adjacent precast concrete wall bodies 1. When installing this retaining wall, first pour and fix the positioning pile 3 into the positioning hole 2, and then the side strengthening rib 4 can completely cover the positioning hole 2 and the wall joint, preventing water from invading through the positioning hole 2 and eroding the positioning pile 3, greatly extending the service life of the positioning pile 3, and making the entire precast concrete wall body 1 more beautiful.

[0039] As Figures 4 to 6 shown, the side strengthening rib 4 includes a first side strengthening rib 41 and a second side strengthening rib 42. The first side strengthening rib 41 is used to cover the positioning hole 2, and the second side strengthening rib 42 is used to cover the wall joint; The width of the first side strengthening rib 41 is greater than the width of the second side strengthening rib 42. In order to ensure that the first side strengthening rib 41 can cover the positioning hole 2 and the second side strengthening rib 42 can cover the wall joint, since the aperture of the positioning hole 2 is much larger than the gap of the wall joint, the width of the first side strengthening rib 41 is designed to be larger, so as to meet the covering of the positioning hole 2 by the first side strengthening rib 41.

[0040] As Figures 5 to 6 shown, a reinforcing rib 7 welded to the wedge-shaped slide rail 5 is also cast and fixed inside the first side strengthening rib 41 and the second side strengthening rib 42; The reinforcing rib 7 is perpendicularly welded and fixed to the wedge-shaped slide rail 5. In order to further improve the fixing effect of the wedge-shaped slide rail 5 inside the side strengthening rib 4, the wedge-shaped slide rail 5 is further strengthened by adding the reinforcing rib 7, so as to ensure the stability and reliability of the casting and fixing of the wedge-shaped slide rail 5.

In order to improve the casting and fixing effect of the positioning pile 3 in the positioning hole 2, since multiple annular grooves 9 and linear grooves 10 are formed on the side wall of the positioning pile 3, during casting, the contact surface between the concrete and the positioning hole 2 and the positioning pile 3 can be increased, and the fixing effect after casting will be better; secondly, the concrete can enter from the hollow cavity 11 and then flow to all the annular grooves 9 and linear grooves 10 through the through holes 12, making the concrete more uniform during casting.

[0042] As Figure 9 shown, a positioning ring 13 is also cast and fixed in each positioning hole 2, and the positioning pile 3 is vertically sleeved in the positioning ring 13 in the positioning hole 2. In order to assist in fixing the positioning pile 3 in the positioning hole 2, a positioning ring 13 is preset in the positioning hole 2. When casting the positioning pile 3, the positioning pile 3 is sleeved in the positioning hole 2, so as to facilitate the subsequent casting of the positioning pile 3.

[0043] The working principle of the present utility model:

[0044] During application, the precast concrete walls 1 are arranged on both sides of the channel in sequence, then the positioning pile 3 is installed in the positioning ring 13 in the positioning hole 2, and then concrete is injected into the positioning hole 2, so as to cast and fix the positioning pile 3 in the foundation of the channel.

[0045] After the concrete in the positioning hole 2 solidifies, the first side reinforcing ribs 41 and the second side reinforcing ribs 42 are installed successively.

[0046] When installing the first side reinforcing ribs 41, the first side reinforcing ribs 41 are installed from top to bottom in the wedge-shaped sliding grooves 6 beside the positioning holes 2 through the wedge-shaped sliding rails 5. At this time, the first side reinforcing ribs 41 can cover all the positioning holes 2 on the same vertical plane, preventing water from invading through the positioning holes 2 and eroding the positioning pile 3, and greatly prolonging the service life of the positioning pile 3.

[0047] When installing the second side reinforcing ribs 42, the second side reinforcing ribs 42 are installed from top to bottom in the wedge-shaped sliding grooves 6 beside the wall through the wedge-shaped sliding rails 5. At this time, the second side reinforcing ribs 42 can cover the wall seams between two adjacent precast concrete walls 1, making the whole precast concrete wall 1 more beautiful.

[0048] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
