Reverse filtering and draining structure for retaining wall

Technical Field

The utility model relates to a retaining wall drainage structures field especially relates to an anti-structure of sluicing of straining of retaining wall.

Background

Retaining walls are a common type of building in the civil engineering field. The traditional retaining wall reverse filtering structure is characterized in that graded broken stones with certain thickness are stacked at the water facing end of a water drain hole and used for draining soil moisture behind a wall, preventing accumulated water behind the wall from forming hydrostatic pressure, reducing frost heaving pressure of backfill behind the wall in a cold area, eliminating expansion pressure of the viscous backfill after being soaked in water and the like.

Traditional retaining wall reversed filter structure needs to pile up layer by layer and lays, and construction quality is wayward, and in the work progress and use after completing, the backfill soil sinks, and reversed filter structure easily shifts, destroys, causes the outlet to block up even, causes the retaining wall drainage inefficacy. The existing 'water filtering bag structure at the rear end of a retaining wall drain pipe' (No. CN 214738239U) wraps the water inlet end of the drain pipe by using a reverse filtering structure and is bound by iron wires, but if the road of a shoulder wall is greatly settled, the water inlet end of a PVC pipe with low strength is easily damaged, even blocks a drain hole, so that the drainage effect is poor, and the 'filtering device inserted into a platform back or a wall back drain hole' (No. CN 215137202U) also faces the problem of damage of the reverse filtering structure when backfill soil is settled. Although the reverse filter bag is small in size and convenient to construct, the problem of damage to a reverse filter structure caused by subsidence of backfill soil is faced. There is a need for an anti-strainer bag construction that is easy to install and secure.

Detailed Description

The present invention will be described in further detail with reference to the accompanying fig. 1-3.

The embodiment of the utility model discloses retaining wall anti-drainage water structure.

Referring to fig. 1, 2 and 3, the retaining wall reverse-filtering water drainage structure comprises a reverse-filtering bag 4, an embedded part 5 and a water sealing layer 6, wherein the reverse-filtering bag 4 wraps a water inlet of a water drainage hole 3 and reversely filters seepage water entering the water drainage hole 3; the anti-filter bag 4 is fixed on the water inlet of the drainage hole 3 by the embedded part 5, and the anti-filter bag 4 and the embedded part 5 are supported on the retaining wall 1 by the water sealing layer 6.

A water drain hole 3 is formed in the retaining wall 1 through an embedded water drain pipe 2, and the water drain pipe 2 is a PVC pipe.

Referring to fig. 1, the reverse filter bag 4 includes a bagged layer 41 and graded broken stones 42, the bagged layer 41 may be made of geotextile or woven bags, in this embodiment, the bagged layer 41 is made of geotextile-supported bags, and workers fill the graded broken stones 42 into the bagged layer 41 to form the reverse filter bag 4. The anti-package of straining 4 carries out the shutoff with the mouth opening that meets water of outlet 3, makes the infiltration can not take away the soil body of retaining wall 1, effectively prevents piping and soil that flows.

Referring to fig. 1, 2, and 3, the embedded part 5 may be a steel wire or a steel wire, and in this embodiment, the embedded part 5 is a steel wire. The iron wire is pre-buried along the circumference interval of outlet pipe 2 has many, and in this embodiment, the iron wire has four. Each embedded part 5 is equally divided into an embedded section and a binding section, the embedded section of each embedded part 5 is embedded into the retaining wall 1 along the length direction of the water drain pipe 2, and the binding sections of the embedded parts 5 are bound with the binding ends of the adjacent embedded parts 5 after passing through the reverse filter bag 4 to fix the reverse filter bag 4. After concrete is poured into the retaining wall 1, the retaining wall 1 and the embedded part 5 form an integral structure, and the stability of the fixed reverse filter bag 4 is improved.

After the water drain pipe 2 is embedded, the embedded section of the embedded part 5 is circumferentially surrounded along the water drain pipe, then the binding section of the embedded part 5 is bent into the cavity of the water drain pipe 2, after the retaining wall 1 is poured with concrete and the template is removed, the binding section of the embedded part 5 is taken out, and then the reverse filter bag 4 is bound and fixed.

In other embodiments, one end of the embedded part 5 may be embedded in the water seal layer, and the other end is bound from the adjacent embedded part 5.

The fixing opening 21 is formed in the water inlet 8 of the water drain pipe 2, the iron wires of the binding sections are clamped with the fixing opening 21, and the phenomenon that concrete enters the water drain pipe 2 to block due to the fact that gaps formed by the pipe opening of the water drain pipe 2 and the embedded part 5 of the bending section are formed when pouring is avoided, and the embedded part 5 does not influence concrete formwork building and concrete pouring.

Referring to fig. 1, the water-sealing layer 6 may be made of clay, concrete or other organic waterproof materials, and in this embodiment, the water-sealing layer 6 is integrally cast on the upstream surface of the retaining wall 1 and is located below the upstream opening of the water drainage hole 3. The holding tank 61 that is used for holding anti-package 4 of straining is offered at the top of water-seal layer 6, and anti-package 4 of straining is arranged in holding tank 61, and holding tank 61 has restricted anti-removal of straining package 4, supports more firmly anti-package 4 of straining under the synergism of built-in fitting 5 and water-seal layer 6. The water sealing layer 6 collects the infiltration, makes the infiltration enter into the outlet pipe 2 through the anti-package of straining 4 and carries out the drainage, effectively avoids the infiltration to enter into the below soil body of outlet pipe 2, improves retaining wall 1's steadiness.
