Description

Technical Field

[0001] This utility model relates to the field of retaining wall construction, specifically to a template for the construction of graded crushed stone filter layer in retaining walls. Background Technology

[0002] Before backfilling the back of a retaining wall, a 50cm thick graded crushed stone filter layer is generally required to facilitate the drainage of water accumulated on the back of the wall through the drainage holes. Because this filter layer is relatively thin, it is usually stacked on the back of the wall using a loader or excavator during the backfilling process to form a filter layer. This results in an uneven thickness of the filter layer, with some parts being too thick and others too thin. It also easily leads to material waste, low formwork efficiency, and even waste of formwork due to some formwork being directly backfilled, which is not conducive to saving construction costs.

[0003] Therefore, to solve the above problems, a template is needed for the construction of the graded crushed stone filter layer of retaining walls, which can ensure the uniform thickness of the filter layer, guarantee construction quality, reduce construction difficulty, improve construction efficiency, reduce resource waste, and control construction costs. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the defects in the prior art and provide a template for the construction of graded crushed stone filter layer in retaining walls, which can ensure the uniform thickness of the filter layer, guarantee the construction quality, reduce the construction difficulty, improve the construction efficiency, reduce resource waste, and control the construction cost.

[0005] The present invention relates to a template for constructing a graded crushed stone filter layer for retaining walls, comprising a template body and a rib plate provided on one side of the end face of the template body, wherein the rib plate has a reference portion with a width consistent with the thickness of the filter layer to be constructed.

[0006] Furthermore, the rib is fixed to the template body, and the rib has a plate-like structure perpendicular to the template.

[0007] Furthermore, the rib is in the shape of a right triangle, with the long side connected to the hypotenuse of the right triangle fixed on the template body, and the short side connected to the hypotenuse of the right triangle having the same thickness as the filter layer to be constructed.

[0008] Furthermore, the rib plate is provided with functional holes.

[0009] Furthermore, there are several functional holes, and these functional holes are located at the rear center of the rib in the width direction.

[0010] Furthermore, the line connecting several of the functional holes forms an arc shape that protrudes outward from the template body.

[0011] Furthermore, the ribs are at least two pieces disposed on the template body, and the two ribs are spaced apart in the height direction of the template body.

[0012] Furthermore, the ribs are a plurality of ribs provided on the template body, the plurality of ribs are parallel, and the plurality of ribs are staggered in the height direction.

[0013] Furthermore, the ribs are detachably mounted on the template body, and the template body has several sets of mounting positions for assembling the ribs.

[0014] This solution also discloses a construction method based on the template used for the construction of the graded crushed stone filter layer of the retaining wall, including the following construction steps:

[0015] S1. Compact the bottom of the filter layer and the bottom of the backfill layer behind the wall to obtain a flat bearing surface;

[0016] S2. Select the preset width and preset number of ribs and install them at the set position on the template body;

[0017] S3. Position the formwork body with ribs on the back side of the retaining wall, with the shortest side of the right-angled triangular ribs facing upwards;

[0018] S4. Simultaneously fill the front and rear sides of the template body with the filter layer filler and the wall back filler, respectively;

[0019] S5. Remove the template body with ribs;

[0020] S6. Repeat steps S3-S5 until the filter layer and the back wall are completely filled.

[0021] The beneficial effects of this utility model are: The template disclosed in this utility model for the construction of graded crushed stone filter layer in retaining walls can be constructed on both sides simultaneously through the template, which can strictly control the construction thickness of the filter layer, resulting in excellent construction quality, greatly saving construction materials, and the construction steps are simple and convenient to operate. The template used can be completely recycled, making it highly economical. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] Figure 1 This is a schematic diagram of the structure of this utility model;

[0024] Figure 2 This is a schematic diagram of the template structure of this utility model;

[0025] Figure 3 This is a schematic diagram of the rib structure of this utility model. Detailed Implementation

[0026] Figure 1As shown in the figure, the construction template for the retaining wall graded crushed stone filter layer 002 in this embodiment includes a template body 1 and a rib plate 2 provided on one side of the end face of the template body 1. The rib plate 2 has a reference portion with a width consistent with the thickness of the filter layer 002 to be constructed, thereby ensuring the thickness of the filter layer 002 through the reference portion and improving the construction quality. When in use, the template body 1 has one side of the rib plate 2 facing the retaining wall 001. The rib plate 2 is detachably set on the template body 1, and the template body 1 has several sets of mounting positions for assembling the rib plate 2. More specifically, the rib plate 2 can be configured according to conventional filter layers. The 002 thickness is available in multiple models. During use, it can be directly assembled onto the template body 1. The template body 1 in this solution is a perforated plate with several holes. The holes have the same diameter, and the ribs 2 are assembled onto the perforated plate in a detachable manner with bolts. This allows the ribs 2 to be fixed at any position on the template body 1, resulting in excellent construction reliability. Furthermore, a reasonable number of ribs 2 can be set according to the length of the template body 1 to improve construction reliability. When the template body 1 with several holes is removed after construction, it can agitate the joint material between the filter layer 002 and the back filler layer. Under the condition of continuous agitation of the holes, the joint position of the two is more secure, resulting in better construction quality.

[0027] In this embodiment, the ribs 2 are at least two pieces disposed on the template body 1, and the two ribs 2 are spaced apart in the height direction of the template body 1; this can further ensure the thickness of the filter layer 002 and prevent the template body 1 from swaying during later construction; more specifically, the ribs 2 are a plurality of pieces disposed on the template body 1, the plurality of ribs 2 are parallel, and the plurality of ribs 2 are staggered in the height direction; the ribs 2 in this solution are roughly in two layers, upper and lower, and the ribs 2 are staggered in the lateral position. This structure forms a plurality of triangular support structures, which can ensure the stability of the structure, thereby ensuring the construction quality, and also reduce the resistance when lifting, making it more convenient to remove the template body 1.

[0028] In this embodiment, the rib plate 2 is detachably fixed to the template body 1, and the rib plate 2 has a plate-like structure perpendicular to the template. More specifically, in this solution, the rib plate 2 is a right-angled triangle, with the long side connected to the hypotenuse of the right-angled triangle fixed to the template body 1, and the short side connected to the hypotenuse of the right-angled triangle having the same thickness as the filter layer 002 to be constructed. That is, the short side connected to the hypotenuse of the right-angled triangle is used as a reference part, resulting in a simple overall structure and reducing subsequent lifting resistance.

[0029] In this embodiment, the rib plate 2 is provided with functional holes 21. There are several functional holes 21 located on the rear side of the middle part of the rib plate 2 in the width direction. The line connecting the several functional holes 21 forms an arc shape that protrudes outward from the template body 1. The opening of the functional holes 21 serves two purposes: firstly, it agitates the filler material of the filter layer 002; secondly, it prevents the root of the rib plate 2 from separating from the template body 1. In particular, the setting of the functional holes 21 closer to the root of the rib plate 2 disperses the pull-out force into the filler material that is pressed against it, thus providing an auxiliary function.

[0030] In this embodiment, the present solution also discloses a construction method based on the construction template for the retaining wall graded crushed stone filter layer 002, including the following construction steps:

[0031] S1. Compact the bottom of the filter layer 002 and the bottom of the backfill layer on the wall back to obtain a flat bearing surface;

[0032] S2. Select the preset width and preset number of ribs 2 and install them at the set position on the template body 1;

[0033] S3. Position the template body 1 with ribs 2 on the rear side of the retaining wall 001, with the shortest side of the right-angled triangular ribs 2 facing upwards;

[0034] S4. The front and rear sides of the template body 1 are simultaneously filled with filter layer 002 and wall backing 003 respectively; the filter layer is filled with 500mm high-grade crushed stone, and the wall backing is filled with backfill soil.

[0035] S5. Remove the template body 1 with ribs 2;

[0036] S6. Repeat steps S3-S5 until the filter layer 002 and the back wall are completely filled.

[0037] The template allows for simultaneous construction on both sides, ensuring strict control over the thickness of the 002 filter layer. This results in superior construction quality, significant savings in building materials, simple and convenient construction steps, and fully recyclable templates, making it highly economical.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
