Description

Novel eccentric catchment outlet

Technical Field

The utility model relates to a wash-out hole technical field, concretely relates to novel eccentric catchment wash-out hole.

Background

The drainage problem needs to be considered when the foundation pit is excavated, the underground water is lowered to the position below the foundation, and the stability of the foundation pit side slope is guaranteed. The drainage of the foundation pit generally comprises open ditch drainage, well point dewatering, blind ditch drainage and the like, when the excavation foundation is not deep or the water quantity is not large, the underground water seeped from the pit wall and the pit bottom is drained through a drainage hole, a part of sand and pebbles are filled in the drainage hole to form a water filtering layer, so that the soil body loss is prevented, but the soil body loss is still serious in the mode.

Disclosure of Invention

To the above problem, the to-be-solved problem of the utility model is to provide a novel eccentric catchment outlet.

In order to solve the problems, the utility model discloses a technical scheme is, a novel eccentric catchment outlet, including drain pipe (1), drainage stopper (3) and geotechnological cloth (5), characterized by: the section of the water filter plug (3) is in an asymmetric U shape, the drain pipe (1) obliquely penetrates into the eccentric groove of the water filter plug (3), the geotextile (5) is arranged between the drain pipe (1) and the water filter plug (3), and the water filter plug (3) is made of high-permeability sand-free concrete.

The section of the water filter plug (3) is in an asymmetric U shape, the total diameter of the bottom surface is 275mm, the heights of the vertical surfaces at the two sides are 200-300mm, wherein the width of the vertical surface at the left side is 50mm, the width of the vertical surface at the right side is 150mm, and the diameter of the bottom surface of the groove is 100 mm.

And the space between the water filtering plug (3) and the water drainage pipe (1) is filled with mortar (4) for compacting and sealing.

The diameter of the drain pipe (1) is 75mm, and the length of the drain pipe is 500 mm.

The drain pipe (1) is made of PVC materials.

The lower part of the drain pipe (1) is uniformly provided with small holes (2) with the diameter of 10mm, and the height of the arrangement range of the small holes (2) is consistent with the height of vertical surfaces on two sides of the U-shaped water filtering plug (3).

The geotextile (5) is embedded and laid in the groove of the water filter plug (3) and completely covers the top ends of the vertical surfaces at the two sides of the water filter plug (3).

The utility model has the advantages that: a filter plug (3) made of sand-free concrete is sleeved on the drain pipe (1), so that water is gathered in the drain pipe (1) as far as possible and flows out, and water cannot be stored at the groove bottom of the groove of the filter plug (3); the utility model discloses the structure is applicable to lower part in the foundation ditch side slope, utilizes the inside a lot of open spaces of no sand concrete, ensures to remain underground water ability and passes through, prevents that silt from spilling over, and has geotechnological cloth (5) of anti-seepage filtration arrange in between drain pipe (1) and drainage stopper (3), avoids drain pipe (1) to become silted up and influence drainage effect.

Detailed Description

The structure of the present invention will be further explained with reference to the accompanying drawings.

The utility model provides a novel eccentric catchment outlet, includes drain pipe (1), filter plug (3) and geotechnological cloth (5), characterized by: the section of the water filter plug (3) is in an asymmetric U shape, the drain pipe (1) obliquely penetrates into the eccentric groove of the water filter plug (3), the geotextile (5) is arranged between the drain pipe (1) and the water filter plug (3), and the water filter plug (3) is made of high-permeability sand-free concrete.

After the sand-free concrete with the proper water-cement ratio is prefabricated, formed and maintained according to the size, the filter plug (3) is manufactured. When a foundation pit is excavated, a water filter plug (3) is pre-buried at a position close to a drain hole at the middle lower part of a side slope, and the water filter plug (3) is outwards inclined by 5%; and geotextile (5) is embedded and laid along the grooves of the water filtering plugs (3) and completely covers the top ends of the vertical surfaces at the two sides of the water filtering plugs (3). One end of the drain pipe (1) which is manufactured in advance according to the size and is provided with the small holes (2) penetrates into the groove of the water filtering plug (3) which is paved with the geotextile (5) in an inclined mode, the inclination of the drain pipe is ensured to be 5%, and then the other end of the drain pipe (1) is exposed out of the foundation pit side slope by about 250 mm. The mortar is filled between the drain pipe (1) and the geotextile (5) at the top ends of the vertical surfaces at the two sides of the water filtering plug (3) by the mortar (4) to be tightly sealed so as to prevent leakage, and because a large number of pores exist in the sand-free concrete in the water filtering plug (3), water flows through the pores and then flows into the drain pipe (1) through the water inlet and the small holes (2) on the drain pipe (1) to be discharged.

Furthermore, the novel eccentric water collecting and draining holes can be uniformly arranged at intervals of 2-3 m.
