Abstract

A drainage structure for a sole plate and a wall surface of an underground building comprises a drainage plate, a steel mesh and concrete layers. The drainage plate comprises a top plate and cup-shaped bodies. A plurality of cup-shaped bodies which are raised towards the bottom surface and arranged uniformly are arranged on the top plate. A drainage channel is arranged between the cup-shaped bodies. The steel mesh is paved on the top plate of the drainage plate. The concrete layers are arranged on the steel mesh and in the cup-shaped bodies of the drainage plate. The utility model has the advantages that after the drainage structure is paved on the original ground, in spite of various reasons, the seeped or leaked water is collected together through the drainage channel formed between the cup-shaped bodies below the drainage plate and is drained by a special drainage device, thereby absolutely preventing water from being leaked from the surface of the drainage structure. Due to simple structure, according to different geology conditions, the height of each cup-shaped body is selected. The drainage structure is applicable to the wall and the ground of a new building and is also used for modifying the old building, thereby completely solving the problem of the leakage of a basement of the building.

Description

The discharge structure that is used for underground building sole plate and surface of wall

Technical field

The utility model relates to a kind of discharge structure that is used for underground building sole plate and surface of wall, is mainly used in to compile to discharge the water be penetrated into underground building sole plate and surface of wall, prevents that the bottom surface from leaking or wet and slippery.

Background technology

The basis, underground building of prior art comprises the discharge structure that is located in the foundation bottom bed course, on bed course, lay three layers of waterproofing course (SBS), again the concrete foundation base plate of 700～800mm, the cement sand levelling after the sole plate surface is with several centimetres when finishing at last.Discharge structure is communicated with collecting well and discharges underground water by drainage pump.Because discharge structure (as gutter) has pressure drag, draining negative pressure decay apart from the zone of drainage pump far-end is bigger, can not satisfy the needs of draining, especially in rainy season, groundwater table is very high, and underground water can not be discharged in the place, cause immense pressure to basal layer, water will be oozed out or overflow to the weak link of basal layer (as the positions such as junction between construction joint, building column and body of wall and the floor), causes ground wet and slippery, or cause coming off of ground decoration layer.And adopt the remedial measure of injecting waterproofing materials is to cure the symptoms, not the disease, and is constantly occurred by new infiltration slit.

Summary of the invention

The utility model aims to provide a kind of discharge structure that is used for underground building sole plate and surface of wall, to solve the problem that underground building sole plate that prior art exists and surface of wall leak.

The technical solution of the utility model is: comprise band drain, gauze wire cloth and layer of concrete, band drain comprises top board and cup shell, is provided with a plurality of uniform cup shells of protruding to the bottom surface on this top board, leaves aquaporin between each this cup shell; Lay gauze wire cloth on the top board of this band drain, be provided with layer of concrete above the gauze wire cloth at this, this layer of concrete is full of in the cup shell of band drain.

On described layer of concrete surface wallboard is housed.

Described band drain is an injection-molded item, the relative opposite side of two couples at the band drain of rectangle is respectively equipped with a plurality of equally spaced projections that cooperatively interact and through hole, this projection of the adjacent edge of a plurality of these band drains inserts in this through hole and connects, and forms more large-area band drain.

The cup shell of described band drain is an inverted truncated cone-shaped or trapezoidal, is equipped with reinforcing rib in the bottom surface of this cup shell and the bottom surface of top board.

Described band drain is fixed on underground building sole plate and surface of wall, and makes this cup shell bottom surface towards this sole plate and surface of wall.

The utility model has the advantages that: on original ground behind this discharge structure of laying, a variety of causes ooze out or the water that spills all the drainage channel that forms of the cup shell below band drain compile Dao Yichu, discharge by special dewatering installation, definitely avoid spilling from the surface of this discharge structure.Simple in structure, can be according to the height of different geological condition selection cup shells, body of wall and ground applicable to the core building also can thoroughly solve the problem that building basement leaks to the transformation of old building.

The specific embodiment

Referring to Fig. 1～Fig. 6, the utility model comprises band drain 9, gauze wire cloth 8 and layer of concrete 7, band drain 9 comprises top board 90 and cup shell 91, is provided with a plurality of uniform cup shells of protruding to the bottom surface 91 on this top board 90, leaves aquaporin (at interval) 12 between each this cup shell 91; On the top board of this band drain 9, lay gauze wire cloth 8, be provided with layer of concrete 7 above the gauze wire cloth 8, charge in the cup shell 91 of band drain below the layer of concrete 7 at this.

Horizontal component in Fig. 1 is that the utility model is applied in the structure sectional view on the sole plate 14, and during construction, the fixing hole 93 that band drain 9 usefulness steel nails 10 pass on the band drain 9 is fixed on the sole plate 14, and these cup shell 91 bottom surfaces are towards this sole plate 14.On band drain 9, lay gauze wire cloth 8, on gauze wire cloth 8, lay concrete then and form layer of concrete 7.Charge into concrete in the cup shell 91 of band drain and form support top layer of concrete 7, and between interval between the cup shell 91 and sole plate 14, formed aquaporin 12, the water that sole plate 14 surfaces spill compiles by crossing aquaporin 12, and is discharged by drainage pump by outfall 13 inflow catch pits.

The part that erect in the left side in Fig. 1 is that the utility model is applied in the structure sectional view on the body of wall 1, its band drain 3, gauze wire cloth 5 and layer of concrete 6 are identical with the structure of above-mentioned band drain 9, gauze wire cloth 8 and layer of concrete 7, and the bottom surface of band drain 3 cup shells is towards body of wall 1.Difference is that layer of concrete 6 has just just covered gauze wire cloth 5, on the surface of this layer of concrete 6 wallboard 4 is housed, and band drain 3 and wallboard 4 are fixing with body of wall 1 by steel nail 2.Interval around the water that body of wall 1 oozes out each cup shell by band drain 3 (crossing aquaporin) 11 is converged and is flowed into outfall 13 with the water that aquaporin 12 flows out crossed on the following sole plate 14.

Described band drain 9 (3) adopts injection moulding to make, the relative opposite side of two couples at the band drain of rectangle is respectively equipped with a plurality of equally spaced projections that cooperatively interact 95 and through hole 92 (referring to Fig. 2), this projection 95 of adjacent edge inserts in this through hole 92 and connects among a plurality of band drain A1, the A2, forms more large-area band drain (referring to Fig. 5, Fig. 6).

The cup shell 91 of described band drain is respectively equipped with reinforcing

rib

94 and 96 for truncated cone-shaped (also can be trapezoidal, cylindricality or other Any shape) in the bottom surface of this cup shell 91 and the bottom surface of top board 90.
