s2, arranging a steel pipe on the back side of the template to support the template;
s3, adding 500mm high-grade crushed stone into the template by using a forklift or a digger, and removing the steel pipe for supporting while paving backfill soil outside the template;
s4, after filling the two sides, extracting the template upwards, rolling and compacting backfill, and tamping the side close to the template by adopting a manual hand-held tamper;
s5, carrying out the construction of the crushed stone and backfill of the upper layer by using the template.
Further, the template is formed by splicing a plurality of steel plates.
Further, the splice of template is provided with the connection floor, be equipped with the quick detach buckle that is used for connecting the template on the connection floor.
Further, the connecting rib plate is arranged in a right triangle shape, and the right-angle side of the connecting rib plate is arranged at the top of the template and has the same width as the thickness of the inverted filter.
Further, a plurality of hanging holes for drawing out the templates are formed in the top of the templates.
Further, the back side of the template is provided with a support rib along the horizontal direction, and the steel pipe is supported on the support rib to support the template.
Further, a plurality of gaps are uniformly formed in the supporting ribs along the length direction of the supporting ribs, and the steel pipes are in one-to-one correspondence with the gaps and are inserted into the gaps to support the template.
In summary, the present invention comprises at least one of the following beneficial effects: through setting up the template, guaranteed the construction quality of wall back drainage layer, reduce the waste of material, ensure the wall back in the process simultaneously and backfill strictly according to design layering construction, guarantee backfill quality.

Detailed Description
Other advantages and effects of the present invention will become apparent to those skilled in the art from the following disclosure, which describes the embodiments of the present invention with reference to specific examples. The invention may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present invention.
The invention is described in further detail below with reference to fig. 1-4.
The embodiment of the invention discloses a construction method of a retaining wall graded broken stone reversed filter layer. Referring to fig. 1 to 4, the construction method of the retaining wall graded broken stone reversed filter layer comprises a template 1 arranged at the retaining wall graded broken stone reversed filter layer, and comprises the following steps:
step one, moving the template 1 to a retaining wall inverted filter, and enabling the template 1 to incline to be parallel to the retaining wall according to the inclination angle of the retaining wall; in order to make the template 1 more convenient to use, template 1 is formed through the concatenation of a plurality of steel sheets, can splice into template 1 of suitable size with the steel sheet according to the job site.
In order to make the assembly and disassembly of the template 1 more convenient, a connecting rib plate 11 is arranged at the splicing position of the template 1, and a quick-release buckle 12 for connecting the template 1 is arranged on the connecting rib plate 11; the connecting rib plate 11 is right triangle, the right-angle side of connecting rib plate 11 sets up in template 1 top and width and inverse filter layer thickness the same, with the pointed end conflict of connecting rib plate 11 on keeping off the wall for template 1 is more accurate in the position when the installation, can play the effect of location to the installation of template 1.
Step two, arranging a steel pipe 2 on the back side of the template 1 to support the template 1; when placing template 1 in barricade reverse filtering layer department, establish with steel pipe 2 at template 1 back side and support template 1, the quantity of steel pipe 2 is according to template 1's size decision, and steel pipe 2 evenly sets up at template 1's back side, and the holding power is more even, can avoid template 1 to be impacted by the rubble and collapse for template 1 installs more firmly.
Simultaneously in order to be able to be more firm that steel pipe 2 supports on template 1 during, the dorsal part of template 1 is equipped with support rib 14 along the horizontal direction, steel pipe 2 supports on support rib 14 supports template 1, and the tip of steel pipe 2 is contradicted in the downside of support rib 14, can avoid steel pipe 2 to appear gliding condition on template 1, and the supporting effect is better.
The supporting ribs 14 are uniformly provided with a plurality of gaps along the length direction of the supporting ribs, the steel pipes 2 are in one-to-one correspondence with the gaps and are inserted into the gaps to support the templates 1, the steel pipes 2 are supported at the gaps of the supporting ribs 14, the situation that the steel pipes 2 sideslip on the templates 1 due to impact force of the templates 1 can be avoided, and the supporting stability is further improved.
Step three, adding 500mm high-grade crushed stone into the template 1 by using a forklift or a digger, and removing the steel pipe 2 for supporting when the backfill soil on the back side of the template 1 is paved outside the template 1, so that the supporting effect on the template 1 can be achieved, and the steel pipe 2 on the back side of the template 1 is completely removed when the backfill soil on the back side of the template 1 is paved to a certain height.
Step four, after filling the two sides, the template 1 is pulled out upwards, backfill soil is compacted, and the side close to the template 1 is compacted by adopting a manual hand-held compactor; when taking out template 1 from between reverse filtering layer and the backfill, in order to make template 1 take out easier, the top of template 1 is provided with a plurality of hanging holes 13 that are used for taking out template 1, uses wire rope to pass hanging holes 13, uses equipment such as jack-up to take out template 1 through wire rope, and it is more convenient to use.
And fifthly, carrying out the construction of the crushed stone and backfill soil of the upper layer by using the template 1, and continuing the steps until the laying of the reverse filtering layer is completed.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present invention, which is intended to be covered by the scope of the claims of the present invention.
