Description

Technical Field

[0001] The utility model relates to the technical field of retaining wall reinforcement, in particular to a mortar stopping structure for retaining walls and the retaining wall. Background Art

[0002] The retaining wall is made of stone sheets, blocks, rough stones, and rubble stones, etc., which are built with slurry to support the roadbed fill and hillside soil structure to prevent the fill or soil from deforming and becoming unstable. Due to internal factors such as the incomplete slurry filling during the construction of the retaining wall, the loose internal structure of the retaining wall, or the influence of external factors such as masonry weathering, water accumulation on the back of the wall, and vehicle loads, the retaining wall is prone to cracking, dislocation, bulging, overturning, and cavitation.

[0003] Therefore, the retaining wall needs to be reinforced. In the prior art, grouting is generally performed inside the retaining wall to improve the hidden defects such as hollowing and bulging inside the retaining wall, thereby improving the strength of the retaining wall and reinforcing the retaining wall in poor technical condition.

[0004] However, this method has certain defects. Due to the characteristics of voids inside the retaining wall and uncontrollable flow of grouting materials, grouting into the retaining wall is very likely to cause slurry leakage, which not only causes material waste but also affects the ecological environment. Utility Model Content

[0005] The utility model aims to provide a grout-stopping structure for a retaining wall, which can effectively prevent the grout in the wall from leaking when the retaining wall is grout-injected for reinforcement.

[0008] As a further improvement of the present invention, second grouting-stopping curtains are respectively disposed at both ends of the first grouting-stopping curtain and are arranged crosswise with the first grouting-stopping curtain, and the second grouting-stopping curtains are extended along the thickness direction of the wall.

[0027] Embodiment 1:

[0028] This embodiment provides a grout-stopping structure for a retaining wall, referring to Figures 1 to 3 , including at least one wall 1, the wall 1 is used to support or block the soil, and a first slurry-stopping curtain is arranged at the bottom of the outer wall surface 11 of the wall 1, and the first slurry-stopping curtain is extended along the thickness direction T of the wall 1. Specifically, the first slurry-stopping curtain includes a plurality of first slurry-stopping holes 12, and the first slurry-stopping holes 12 are opened along the thickness direction T of the wall 1. The plurality of first slurry-stopping holes 12 are arranged at intervals along the length direction L of the wall 1, and each first slurry-stopping hole 12 is filled with a slurry-stopping material, which has the function of isolating the fluid. The slurry-stopping material filled in the first slurry-stopping hole 12 can prevent the slurry from flowing out. This method has a simple structure and is easy to implement. The plurality of first slurry-stopping holes 12 and the slurry-stopping materials therein are combined to form a first slurry-stopping curtain, and the first slurry-stopping curtain can prevent the slurry inside the wall 1 from leaking from the bottom surface of the wall 1.

[0029] At the same time, in order to prevent the slurry from flowing out from the two sides of the wall 1, second slurry-stopping curtains are respectively arranged at both ends of the first slurry-stopping curtain, and the two second slurry-stopping curtains are respectively arranged to cross one end of the first slurry-stopping curtain, and the second slurry-stopping curtains are extended along the thickness direction T of the wall 1. Specifically, the second slurry-stopping curtain includes a plurality of second slurry-stopping holes 13, and the second slurry-stopping holes 13 are opened from the outer wall surface 11 along the thickness direction T of the wall 1. The plurality of second slurry-stopping holes 13 are arranged at intervals along the height direction H of the wall 1, and each second slurry-stopping hole 13 is filled with The slurry stopping material, a plurality of second slurry stopping holes 13 and the slurry stopping materials filled therein are combined to form a second slurry stopping curtain. The two second slurry stopping curtains can prevent the slurry in the wall 1 from leaking outward from both sides of the wall 1. At the same time, since the first slurry stopping curtain and the second slurry stopping curtain are cross-arranged, that is, the two are connected together, the two are combined to form an area for blocking the outflow of slurry. The positions of the first slurry stopping curtain and the second slurry stopping curtain can be set according to the grouting area, thereby improving the blocking efficiency of the slurry and helping to save construction costs.

[0030] Further, see Figure 2~3 The multiple first slurry-stopping holes 12 and the multiple second slurry-stopping holes 13 can be arranged in multiple rows or a single row. When arranged in multiple rows, they can play a multiple barrier role on the slurry and further reduce slurry leakage.

[0031] In this embodiment, the depth of the first slurry-stopping curtain and the second slurry-stopping curtain extending along the thickness direction T of the wall 1 should be 1 / 2 to 1 / 3 of the thickness of the wall 1. On the one hand, if the depth is too deep, it is easy to destroy the overall structure of the wall 1, thereby causing the wall to collapse. On the other hand, if the depth is too shallow, it affects the barrier effect of both on the slurry.

[0032] Furthermore, in order to prevent the slurry in the wall 1 from leaking out from the outer wall surface 11 after grouting, a protective wall panel 3 is laid on the outer wall surface 11. The protective wall panel 3 covers the outer wall surface 11 as a whole. The protective wall panel 3 can be cast by concrete. At the same time, a plurality of connecting holes 4 corresponding to the plurality of first grouting holes 12 and the plurality of second grouting holes 13 are arranged on the protective wall panel 3, that is, the grouting material can be filled into the first grouting holes 12 and the second grouting holes 13 through the connecting holes 4. During actual construction, it is not necessary to directly open the first stop-grouting hole 12 and the second stop-grouting hole 13 on the exterior wall surface 11. First, the protective wall panel 3 is laid on the exterior wall surface 11, and then the connecting hole 4 is drilled on the protective wall panel 3. When drilling the connecting hole 4, the first stop-grouting hole 12 and the second stop-grouting hole 13 are opened at the same time, which helps to improve the construction efficiency. At the same time, the provision of the protective wall panel 3 can not only strengthen the wall body 1, but also protect the exterior wall surface 11, thereby avoiding damage to the structure of the wall body 1 caused by directly opening the first stop-grouting hole 12 and the second stop-grouting hole 13 on the exterior wall surface 11.

[0033] In this embodiment, the stopper is preferably water glass, which not only has a waterproof function, but also solidifies in the air and can play a bonding role, thereby reinforcing the wall 1 to a certain extent.

[0034] Embodiment 2:

[0035] The present embodiment provides a retaining wall, comprising a plurality of walls 1, each of which is provided with the slurry stopping structure of the above-mentioned technical solution. In order to avoid damage between the plurality of walls 1 caused by uneven settlement of the foundation, the plurality of walls 1 are spaced apart so that settlement joints 5 are formed between the plurality of walls 1, and buffer materials are filled in the settlement joints 5. The buffer materials can, on the one hand, reduce damage to the structure of the wall 1 caused by the settlement of the wall 1, and on the other hand, can isolate two adjacent walls 1 to avoid damage to the structure of the settlement joint 5 caused by slurry leakage.

[0036] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the utility model.
