Abstract

The utility model provides a novel structure of quick separation piping to the piping passageway of the following formation of former ground line geotechnological cloth is laid in piping passageway export, lays the wire net at geotechnological cloth, lays the ballast rubble on the wire net. The utility model discloses in, geotechnological cloth can effectively the separation silt particle be taken out but can make the clear water flow out, and the wire net of geotechnological cloth top can protect geotechnological cloth not broken by gushing water or the destruction of having swelled to a certain extent, and the rubble of geotechnological cloth top can play the ballast effect, plays and prevents that piping export geotechnological cloth and the destroyed effect of wire net. The whole piping blocking structure is simple and reliable, the construction is rapid and convenient, no energy-consuming power equipment is provided, the continuous damage of piping channels can be effectively prevented in the construction process, the mud and sand of the water retaining structure are protected from being brought out, and the instability of the water retaining structure is prevented.

Description

Novel structure of quick separation piping

Technical Field

The utility model relates to a novel structure of quick separation piping is applicable to effective separation use when the piping appears in retaining structures such as earth and rockfill dam (weir), fill sand tube bag cofferdam.

Background

In hydropower or other municipal and building engineering, piping usually occurs in the water retaining process of water retaining building engineering such as earth and rockfill dams, sand-filled pipe bag cofferdams and the like, so that earth and rock or silt in the water retaining building are brought out by water flow to destroy the stability of the water retaining building. In order to prevent soil, stone or silt in the water-stopping building from being carried out, sand bags, soil, stones and the like are usually and quickly backfilled at the position of a piping outlet to prevent a silt mixture at the piping outlet from flowing out and prevent the water-stopping building from being unstable. However, when the sand bag and the soil and stone are backfilled at the piping outlet, the sand mixture at the piping outlet is blocked, and simultaneously, the water flow is easily blocked, so that the piping is redirected, a new piping channel phenomenon is induced, and the risk of stable damage of a water retaining structure is possibly caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: to the problem that above-mentioned exists, provide a novel structure of quick separation piping, simple structure is reliable, the construction is quick convenient, operation safety, expense are lower, effectively prevent the piping destruction. Therefore, the utility model adopts the following technical scheme:

the utility model adopts the technical proposal that: the utility model provides a novel structure of quick separation piping which characterized in that: and for a piping channel formed below the original ground line, laying geotextile at an outlet of the piping channel, laying a steel wire mesh on the geotextile, and laying ballast macadam on the steel wire mesh.

The utility model discloses in, geotechnological cloth can effectively the separation silt particle be taken out but can make the clear water flow out, and the wire net of geotechnological cloth top can protect geotechnological cloth not broken by gushing water or the destruction of having swelled to a certain extent, and the rubble of geotechnological cloth top can play the ballast effect, plays and prevents the destroyed effect of piping export geotechnological cloth and wire net. The whole piping blocking structure is simple and reliable, the construction is rapid and convenient, no energy-consuming power equipment is provided, the continuous damage of piping channels can be effectively prevented in the construction process, the mud and sand of the water retaining structure are protected from being brought out, and the instability of the water retaining structure is prevented.

Fig. 1 is a sectional view of the present invention in practical application.

Detailed Description

As shown in fig. 1, a water retaining structure 1 on a site forms a piping passage 3 below a main surface line 2, and an outlet of the piping passage is directed substantially upward. The utility model discloses a geotechnological cloth 5 is laid to novel structure of quick separation piping in piping passage outlet 4, geotechnological cloth 5 top sets up one deck wire net 6, rubble 7 is laid to wire net 6 top, and like this, 4 silt of piping passage outlet is by the nevertheless water permeable of geotechnological cloth 5 separation, avoid blocking rivers, lead to the piping to change the course, wire net 6 is laid on geotechnological cloth 5, protection geotechnological cloth 5 does not receive destruction, rubble 7 is laid on wire net 6, protection geotechnological cloth 5 and wire net 6 are not washed away, prevent that piping passage outlet 4 is destroyed, thereby it does not receive destruction to protect retaining building thing 1.

Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art can change, add or replace the above examples within the scope of the present invention.

Claims (1)
