Abstract

The utility model discloses a drainage blind ditch on the outer side of an exterior wall of a basement. The drainage blind ditch is of a layered structure, is built on a cushion layer on the outer side of the exterior wall of the basement and sequentially comprises a coarse sand water filtering layer and a gravel water permeating layer from outside to inside, and the coarse sand water filtering layer and the gravel water permeating layer are separated by a brick wall on the side face and separated by geotechnical cloth on the top face. By the drainage blind ditch, underground water can be effectively drained, water level on the outer side of the basement is lowered, water pressure on a building body concrete structure is reduced, the technical problem of drainage after backfill of the exterior wall is solved, and quality and safety of the building body structure are guaranteed.

Description

Weeper drain outside a kind of outer wall of basement

Technical field

The utility model relates to draining field, underground structure, relates to specifically weeper drain outside a kind of outer wall of basement.

Background technology

In Basement Concrete Structures construction, the general mode of open drain and collecting well that adopts is carried out draining, but after exterior wall backfill completes, this drainage pattern cannot effectively be got rid of underground water, cause water level outside basement to raise, be very easy to cause the generation of anti-floating accident, thereby affect quality and the safety of major structure of construction.

Utility model content

Technical problem to be solved in the utility model is just to provide weeper drain outside a kind of outer wall of basement.

The utility model adopts following technical scheme:

Weeper drain outside a kind of outer wall of basement, described french drain is layer structure, is built in outside outer wall of basement on bed course, is followed successively by from outside to inside coarse sand drainage layer and rubble pervious layer, coarse sand drainage layer and rubble pervious layer are separated by with brick wall in side, at end face, with geotextiles, are separated by.

Further, described french drain communicates with drainage pipe or collecting well.

The beneficial effects of the utility model are:

Weeper drain outside outer wall of basement disclosed in the utility model, can effectively get rid of underground water, reduce the water level in basement outside, reduce the water pressure to building body concrete structure, solve the technical barrier of draining after exterior wall backfill, guaranteed quality and the safety of major structure of construction.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model embodiment 1 weeper drain.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

Embodiment 1, please refer to Fig. 1, this embodiment discloses weeper drain outside a kind of outer wall of basement, described french drain is layer structure, be built on outer wall of basement 1 outside bed course 2, be followed successively by from outside to inside coarse sand drainage layer 3 and rubble pervious layer 4, coarse sand drainage layer and rubble pervious layer are separated by with brick wall 5 in side, at end face, with geotextiles 6, are separated by.Described french drain communicates with drainage pipe, utilizes ground to discharge by water, or described french drain communicates with collecting well, utilizes drainage pump that water is discharged.
