Description

Technical Field

[0001] The utility model relates to the technical field of retaining walls, in particular to a buttress retaining wall used for buildings with large height differences in hilly landforms. Background Art

[0002] A retaining wall is a structure that supports the roadbed fill or hillside soil and prevents the fill or soil from deforming and becoming unstable. In the cross section of a retaining wall, the part that is in direct contact with the supported soil is called the wall back; the part facing the air opposite to the wall back is called the wall face; the part that is in direct contact with the foundation is called the base; the top surface of the wall opposite to the base is called the wall top; the front end of the base is called the wall toe; and the rear end of the base is called the wall heel.

[0003] Among them, the buttress retaining wall is a reinforced concrete thin-wall retaining wall, which is characterized by adding a buttress at a certain distance along the vertical arm of the cantilever retaining wall to connect the vertical arm with the heel plate. This structural form can reduce the internal force, thickness and amount of steel bars between the vertical wall and the inner bottom plate, thereby improving the stability of the entire structure. The main advantages of the buttress retaining wall include: simple structure, convenient construction, small wall section, light weight, better performance of material strength, and adaptability to foundations with low bearing capacity. In addition, it also has the advantages of saving space, shortening construction period, and beautifying the urban environment. Therefore, it is particularly suitable for areas lacking stone materials and earthquake areas. At the same time, it is also a commonly used retaining wall form in the approach of overpasses in urban highway projects.

[0004] However, for the drainage pipe of a common buttress retaining wall, after the soil covers one end of the drainage pipe, the soil will easily block the filter holes at one end of the drainage pipe, resulting in poor drainage. Rainwater is squeezed in the soil on one side of the buttress retaining wall, increasing the pressure on the buttress retaining wall. In view of this, the present application proposes a buttress retaining wall for buildings with large height differences in hilly areas. Utility Model Content

The filter head 4 filters the soil to prevent the soil from entering the drainage pipe 3.

[0024] The anti-blocking assembly 5 includes a movable plate 51 slidably mounted inside the filter head 4 , a plurality of dredging rods 52 are fixedly mounted on one side of the movable plate 51 , and a control rod 53 is fixedly mounted on the other side of the movable plate 51 .

[0025] Secondly, a plurality of filter holes 41 are provided on one side of the filter head 4, and the number and position of the filter holes 41 are the same as the number and position of the dredging rods 52. When the filter holes 41 are clogged with mud, the control rod 53 drives the moving plate 51 to approach the filter holes 41, so that the dredging rods 52 push the mud in the filter holes 41 and dredge the filter holes 41.

[0026] At the same time, a connecting threaded pipe 42 is fixedly installed on one side of the filter head 4 close to the drain pipe 3, and the connecting threaded pipe 42 is threadedly installed inside the drain pipe 3. During installation, the control rod 53 passes through the drain pipe 3, and then the filter head 4 is threadedly installed at one end of the drain pipe 3 through the connecting threaded pipe 42.

[0027] Among them, a reset spring 6 is fixedly installed on one side of the movable plate 51, and a water permeable hole 511 is opened on one side of the movable plate 51. After the dredging is completed, the control rod 53 is released, the reset spring 6 is reset, and the movable plate 51 is pulled inward, so that the dredging rod 52 and the filter hole 41 are separated.

[0028] Secondly, one end of the control rod 53 extends to the outside of the other end of the drain pipe 3, and a pressing head 531 is fixedly installed on the end of the control rod 53 located outside the drain pipe 3. When unblocking, the staff presses the pressing head 531 to increase the force bearing area, which is convenient for unblocking.

[0029] Meanwhile, a buttress plate 7 is fixedly mounted on the top of the bottom plate 1 , and one side of the buttress plate 7 is fixedly connected to one side of the wall panel 2 .

[0030] A wall connection groove 101 is provided at the top of the bottom plate 1 and below the wall panel 2 , and a buttress reinforcement groove 102 is provided at the top of the bottom plate 1 and below the buttress plate 7 .
