Description

A kind of novel barricade anti-filter discharge structure

Technical field

The utility model relates to the native technical field of drainage of gear, particularly relates to a kind of novel barricade anti-filter discharge structure.

Background technology

Loaded filter, as the important component part of retaining structure, is stablized to maintain barricade for getting rid of wall back of the body soil body ponding, and running off in generation seepage failure etc. preventing the soil body all plays an important role.In the design and construction process of retaining structure, engineers and technicians often attach great importance to the main part of retaining structure, and design and the detailed inspection of having carried out system are calculated, and pay close attention to not to loaded filter, do not carry out the design of autonomous system.

In prior art, what loaded filter generally adopted is bagged sand gravel.In the design and construction process of reality, mainly there is the deficiency of the following aspects in bagged sand gravel loaded filter:

(1) engineering time is longer, and the loaded filter construction in excavation location is after soil excavation completes, and in wall back of the body place, code block forms from bottom to top, takes longer, easily causes interim excavation slope to produce local buckling because open-assembly time is longer;

(2) difficulty of construction is large, and because wall back slope rate is comparatively steep or even upright, and loaded filter thickness is relatively thin, and the difficulty that code builds construction is comparatively large, and particularly when barricade is higher, self-stability is poor, is more difficult to construction;

(3) construction quality is wayward, because loaded filter is relatively thin, the wall back of the body also out-of-flatness that excavation is formed, and design is also without clear and definite compactness standard-required, the loaded filter that code is built generally is difficult to closely knit and uneven thickness, affects the performance of its anti-filter, drain function;

(4) reliable quality determining method is lacked.

Utility model content

The utility model provides a kind of novel barricade anti-filter discharge structure, to solve in prior art the loaded filter engineering time compared with long, difficulty of construction is large, the uppity technical problem of quality.

The purpose of this utility model is achieved through the following technical solutions:

A kind of novel barricade anti-filter discharge structure, comprise water barrier 1, draining web-roll core 2 and loaded filter 3, wherein, described draining web-roll core 2 is located between described water barrier 1 and described loaded filter 3, described water barrier 1 is close to retaining wall 4, the ground location of described retaining wall 4 is provided with header 5 and tapping pipe 6, and described retaining wall 4 is provided with spilled water hole 7.

Technique effect of the present utility model is:

Structure is simple, and building time is short, has good drain function, and has some strength, and when avoiding concreting, concrete invades anti-filter discharge structure blocking drainage channel simultaneously, ensures drainage effect.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation that in the utility model, header is connected with tapping pipe;

Fig. 3 is the schematic diagram that in the utility model, draining web-roll core stretches into header.

Detailed description of the invention

For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in further detail the utility model below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, for a kind of novel barricade anti-filter discharge structure that the utility model provides, comprise water barrier 1, draining web-roll core 2 and loaded filter 3, wherein, described draining web-roll core 2 is located between described water barrier 1 and described loaded filter 3, described water barrier 1 is close to retaining wall 4, and the ground location of described retaining wall 4 is provided with header 5 and tapping pipe 6, and described retaining wall 4 is provided with spilled water hole 7.

Wherein, described header 5 and described tapping pipe 6 are PVC material.Described draining web-roll core 2 is geosynthetics composite construction.As shown in Figure 2, described header 5 is connected with described tapping pipe 6 by tee junction.The all upper halfs of described header 5 pipe are provided with fluting 8 as shown in Figure 3, and described draining web-roll core 2 stretches in described fluting 8.

Loaded filter 3 is geosynthetics composite construction, has soil conservation, permeable, silting blocking effect, has the features such as material is light, construct convenient, reliable in quality, good endurance; Draining web-roll core 2 has good drain function, and has some strength, has slow down effect to the pressure acting on retaining wall; Water barrier 1 effectively intercepts has rodent ambient water corrosion concrete barricade, and when avoiding concreting, concrete invades anti-filter discharge structure blocking drainage channel simultaneously, ensures drainage effect.Header 5 has played the effect of collecting sluicing face bottom range soil body ponding; The water of header 5 is discharged outside barricade by tapping pipe 6.

Retaining wall 4 to be carried on the back by spilled water hole 7, header 5 and tapping pipe 6 and is effectively connected into a complete drainage system by the utility model, is effectively discharged outside barricade by wall backwater in time.

Be understandable that, the system architecture shown in figure does not form the restriction to system, can comprise the equipment more more or less than diagram, or combine some equipment, or different deployed with devices.

Above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
