Description

Technical Field

[0001] The invention relates to the field of retaining wall construction, and in particular to a construction template and a construction method for a graded crushed stone filter layer of a retaining wall. Background Art

[0002] Before backfilling the back of the retaining wall, it is generally necessary to build a 50cm thick graded crushed stone filter layer to facilitate the drainage of accumulated water on the back of the wall through the drainage holes. Since the thickness of the filter layer is relatively thin, a forklift or excavator is generally used to pile up water on the back of the wall during the backfilling process to form a water filter layer, resulting in uneven thickness of the water filter layer, with some parts being too thick and some parts being too thin, and easily resulting in material waste. In addition, the formwork efficiency is low, and even some formwork is directly backfilled to waste the formwork, which is not conducive to saving construction costs.

[0003] Therefore, in order to solve the above problems, a construction template and construction method for the graded crushed stone filter layer of the retaining wall are needed, which can ensure the consistency of the thickness of the filter layer, ensure the construction quality, reduce the construction difficulty, improve the construction efficiency, reduce resource waste, and control the construction cost.

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

[0023] Figure 1 It is a structural schematic diagram of the present invention;

[0024] Figure 2 It is a schematic diagram of the template structure of the present invention;

[0025] Figure 3 It is a schematic diagram of the rib structure of the present invention. DETAILED DESCRIPTION

[0026] Figure 1It is a structural schematic diagram of the present invention. As shown in the figure, the construction template for the graded crushed stone filter layer 002 of the retaining wall in this embodiment includes a template body 1 and a rib plate 2 arranged on one side of the end face of the template body 1, wherein the rib plate 2 has a reference portion whose width is consistent with the thickness of the filter layer 002 to be constructed, and then the thickness of the filter layer 002 is guaranteed by the reference portion, thereby improving the construction quality; when the template body 1 is in use, one side of the rib plate 2 faces the retaining wall 001, and the rib plate 2 is detachably arranged on the template body 1, and the template body 1 has a plurality of groups of mounting positions for assembling the rib plate 2; more specifically, the rib plate 2 can be arranged according to the conventional filter layer 001. 02 There are many types of thickness settings, which can be directly assembled on the template body 1 when used. The template body 1 described in this solution is a hole plate with a plurality of holes. The hole diameters of the hole plate are consistent, and the rib plate 2 is assembled on the hole plate in a detachable manner by bolts, so that the rib plate 2 can be fixed at any position of the template body 1, and the construction reliability is excellent. A reasonable number of rib plates 2 can be set according to the length of the template body 1 to improve the construction reliability. The template body 1 with a plurality of holes can stir the joint materials of the filter layer 002 and the back filling layer when taken out after construction, so that the joint position of the two is more secure under the condition of continuous stirring of the holes, and the construction quality is better.

[0027] In this embodiment, the ribs 2 are at least two pieces arranged on the template body 1, and the two ribs 2 are spaced apart in the height direction of the template body 1; the thickness of the filter layer 002 can be further ensured to prevent the deflection of the template body 1 caused by the later construction; more specifically, the ribs 2 are several pieces arranged on the template body 1, several of the ribs 2 are parallel, and several of the ribs 2 are staggered in the height direction; the ribs 2 in this solution are roughly in two layers, and the ribs 2 are staggered in the horizontal position. The structure forms several triangular supporting structures, which can ensure the stability of the structure and thus ensure the construction quality, and the resistance is lower when pulling, which is more convenient for removing the template body 1.

[0028] In this embodiment, the rib plate 2 is detachably fixed on the template body 1, and the rib plate 2 is a plate-shaped structure perpendicular to the template. More specifically, in this solution, the rib plate 2 is a right triangle, the long side connected to the hypotenuse of the right triangle is fixed on the template body 1, and the short side connected to the hypotenuse of the right triangle is consistent with the thickness of the filter layer 002 to be constructed, that is, the short side connected to the hypotenuse of the right triangle is used as a reference part, the overall structure is simple, and the subsequent pulling resistance can be reduced.

[0029] In this embodiment, the rib plate 2 is provided with a plurality of functional holes 21, which are located at the middle rear side of the rib plate 2 in the width direction, and the connecting line of the plurality of functional holes 21 is in an arc shape that bulges outward away from the template body 1. The opening of the functional holes 21 has the function of stirring the filler of the filter layer 002, and also prevents the root of the rib plate 2 from separating from the template body 1. In particular, the functional holes 21 are arranged closer to the root of the rib plate 2, so that the pulling force is dispersed to the filler pressed against it due to the arrangement of the functional holes 21, thereby playing an auxiliary function.

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

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

[0032] S2. Select a preset width and a preset number of ribs 2 to be installed at a set position of the template body 1;

[0033] S3. The formwork body 1 with ribs 2 is positioned on the rear side of the retaining wall 001, with the shortest side of the right-angled triangle rib 2 facing upward;

[0034] S4. The filter layer 002 filler and the wall back 003 filler are filled on the front and rear sides of the template body 1 respectively; the filter layer filler is 500mm high-grade gravel, and the wall back filler is 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 filled.

[0037] The templates set up can be used for construction on both sides at the same time, and the construction thickness of the filter layer 002 can be strictly controlled. The construction quality is excellent, and construction materials can be greatly saved. The construction steps are simple and the operation is convenient. The templates used can be completely recycled, and the economy is high.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
