Description

Technical Field

[0001] The invention relates to the technical field of assembled structures, and in particular to an assembled filter layer structure of a retaining wall and a construction method thereof. Background Art

[0002] The purpose of the retaining wall is to prevent deformation of the rear base and to play a supporting role. The construction of the retaining wall requires the application of an indispensable filter layer civil engineering structure on the rear side. The filter layer is mainly composed of multiple layers of sand, gravel or pebbles with different particle sizes. The particles are arranged in a gradually increasing manner to ensure that water can flow smoothly through the retaining wall drainage pipe, which can effectively prevent pipe bursts and soil particle loss.

[0003] However, the conventional construction method of the filter layer is time-consuming and laborious. The vertical laying of gravel with gradually changing particle sizes makes its construction extremely inconvenient. In addition, the gaps between the large-grained gravel of the adjacent substrates cause partial infiltration of soil particles, which reduces the construction quality and poses construction risks. It also makes subsequent maintenance and repair extremely inconvenient.

[0004] Therefore, we consider designing an assembled filter layer structure to achieve rapid construction and at the same time alleviate the problem of soil particles in the matrix penetrating into the gaps between sand and gravel, so as to facilitate later inspection and maintenance. In view of this, we propose a retaining wall assembled filter layer structure and its construction method. Summary of the invention

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0049] See also Figure 1-9 The present invention describes the above technical solution in detail through the following embodiments:

[0050] A retaining wall assembled filter layer structure, arranged behind a retaining wall body 1, comprises:

[0051] The supporting ear wall 2 is used to support and fix the retaining wall body 1. The supporting ear wall 2 and the retaining wall body 1 of this embodiment are both concrete structures. In order to fix the connection, steel bars are embedded between the two so that the two maintain a relatively fixed position relationship to avoid the subsequent assembly unit 3 from shifting.

[0052] Assembly unit 3 is used to fill the filter material to prevent the loss of soil particles, such as Figure 5-Figure 7 The structure shown includes two side assembly bins 32 detachably installed inside the supporting ear wall 2 and symmetrically arranged on both sides, and at least one middle assembly bin 31 installed between the two side assembly bins 32 .

[0053] It should be noted that in order to prevent the assembly unit 3 from being stolen at will after installation, a locking anti-theft structure is provided between the middle assembly compartment 31 and the side assembly compartment 32 to prevent the assembly unit 3 from being directly disassembled and extracted.

[0054] Specifically, in order to facilitate the installation of the assembly unit 3 at the support ear wall 2, the support ear wall 2 of this embodiment is as follows: Figure 4 The structure shown includes two side wall panels 21 and a bottom plate 22 that are fixedly connected. The two side wall panels 21 and the bottom plate 22 are in a C-shaped structure with the opening facing upward. A vertically arranged protrusion 211 is provided on the inner side of the side wall panel 21, and a vertically arranged positioning rod 23 is provided on the bottom plate 22.

[0055] The side assembly bin 32 is provided with a side limit groove 321 for being inserted into the protrusion 211, and the middle assembly bin 31 and the side assembly bin 32 are respectively provided with a first slot 311 and a second slot 322 for being inserted along the positioning rod 23 at the connecting bin walls, so that the assembly unit 3 can be positioned and installed by the protrusion 211 and the positioning rod 23.

[0056] The assembly unit 3 of the present embodiment is a prefabricated component, which is easy to disassemble and assemble, avoiding the problem of traditional disordered filling of sand and gravel in the filter layer, and is easy to repair and replace later, with strong operability, convenient and efficient use; the present embodiment is provided with three rows of two-layer assembly units 3 from the inside to the outside, and other embodiments can select assembly units 3 of different numbers according to the fixing requirements and the requirements of the filter layer construction; specifically, in order to facilitate disassembly and assembly construction, the middle assembly bin 31 and the side assembly bin 32 are respectively detachably installed with bin covers 33 on the top, and the bin covers 33 are installed with handles for easy taking and placing, and the bottoms of the middle assembly bin 31 and the side assembly bin 32 are provided with embedding grooves 301 corresponding to the handle positions, which can maintain installation stability.

[0057] like Figure 7 In the structure shown, a first filling inner bin 312 is detachably installed inside the middle assembly bin 31, and a second filling inner bin 323 is detachably installed inside the side assembly bin 32; as the essence of the filter layer structure is filteration, the first filling inner bin 312 and the second filling inner bin 323 can be filled with existing sand and gravel structures of different gradations. Through-hole structures are provided on the walls of the first filling inner bin 312, the second filling inner bin 323, the middle assembly bin 31 and the side assembly bin 32. In order to prevent the loss of sand and gravel with smaller particle sizes from the through-hole structures, permeable geotextiles are installed on the inner walls of the middle assembly bin 31 and the side assembly bin 32 in this embodiment.

[0058] The specific structure of the locking anti-theft structure is as follows Figure 8 In the structure shown, first inclined panels 3121 are provided on both sides of the bottom of the first filling inner warehouse 312, and inclined sliders 313 are slidably installed on both sides of the bottom of the intermediate assembly warehouse 31 through first springs 314, and convex plates 3131 are provided on the outer sides of the inclined sliders 313; when the first filling inner warehouse 312 is inserted, the first inclined panels 3121 are used to squeeze the inclined sliders 313 through the warehouse body of the intermediate assembly warehouse 31 and move outward.

[0059] And if Fig. 9 In the structure shown, second inclined panels 3231 are provided on both sides of the bottom of the corresponding second filling inner warehouse 323, and blocks 324 are slidably installed on both sides of the bottom of the side assembly warehouse 32 through second springs 325. The blocks 324 are provided with a slot 3241 for clamping the convex plate 3131. After insertion, the inclined slider 313 and the block 324 will be clamped with each other, and the convex block 211 is provided with a clamping groove for clamping the block 324 on one side of the side limit groove 321. At this point, an overall clamping and fixing effect can be formed. After packaging, any assembly unit 3 cannot be lifted up when extracted, so a locking and anti-theft structure is realized.

[0060] The construction method of the assembled filter layer structure of the retaining wall in this embodiment has the following specific steps:

[0061] Step 1: First, construct the retaining wall body 1 in front of the base, and excavate a horizontal foundation pit between the retaining wall body 1 and the base. Figure 1-Figure 2 , Figure 4 In the structure shown, a supporting ear wall 2 is constructed behind the retaining wall body 1, the supporting ear wall 2 is connected by pre-buried steel bars, and the bin covers 33 on all the intermediate assembly bins 31 and the side assembly bins 32 are opened for standby use;

[0062] Step 2: Take out the first filling inner bin 312 and the second filling inner bin 323 in the middle assembly bin 31 and the side assembly bin 32 and fill them with filter layer materials for standby use, and set the size of the sand and gravel filled in the assembly unit 3 from the base to the retaining wall body 1 to decrease step by step;

[0063] Step 3: First, insert the assembly unit 3 layer by layer from bottom to top at the supporting ear wall 2, and then insert the first filling inner bin 312 and the second filling inner bin 323 prepared in step 2 into the corresponding middle assembly bin 31 and the side assembly bin 32 respectively, and press the inclined slider 313 and the clamping block 324 to form a locking anti-theft structure;

[0064] Step 4: Use the bin cover 33 to encapsulate the middle assembly bin 31 and the side assembly bin 32. In this embodiment, the assembly unit 3 structure is made of metal stainless steel. After years of use, the bin will continue to be damaged. You only need to remove the bin cover 33 and loosen the locking anti-theft structure, take it out from bottom to top and replace it with a new component. Subsequent maintenance after construction is efficient and simple, and the assembly unit 3 can also prevent the internal anti-filter material from being lost.
