Abstract

The utility model discloses a prefabricated concrete plate-type combined box drain, and relates to an improvement on drainage equipment in cities and towns. The box drain comprises a bottom plate, walls and a cover plate. A sand cushion layer is laid at the bottom of the box drain, the bottom plate is arranged on the sand cushion layer, grooves are formed in the bottom plate, the insides of the grooves are connected with the walls through cement mortar, fine protection stone concrete angle beads are arranged on the walls and the upper surface of the bottom plate, the cover plate is arranged on the upper portions of the walls, the walls are connected with the cover plate through the cement mortar in a filling mode, and accordingly one box drain is formed; each box drain is connected with an adjacent box drain through bell mouths and insertion openings formed in the two ends of the walls of each box drain, and the bottom plates, the walls and the cover plates of the box drains are filled with expanding cement for connection. The box drain solves the problems that in the prior art, the existing technology is limited by construction sites, the number of influence factors of construction quality is large, and long time is consumed during construction.

Description

The board-like combination box drain of a kind of precast concrete

Technical field

The utility model relates to a kind of improvement of urban drainage equipment.

Background technology

Gutter refer to by near roadbed, in cropland, near water that house, low-lying place collects guides the ditch beyond roadbed, cropland, house ground into.There is two kinds, open drain and covered conduit.Gutter is designed according to drainage system engineering layout and engineering specification, determines field drainage trench depth and spacing, and flow, water level, cross dimensions and the engineering quantity of analytical calculation drainage channels at different levels and building.Field drainage net spacing of drainage ditches and cross dimensions are required to determine by drainage requirement and tractor-ploughing.In prior art, draining box drain adopts brick, stone or concrete piece to build by laying bricks or stones mostly, need to manually build by laying bricks or stones having excavated in groove one one; Indivedual concrete cast-in-place constructions that adopt, need on-the-spot assembling reinforcement, installation form, build, vibrate, the working procedure such as maintenance.These products, construction speed is slow, and construction quality is affected greatly by On-the-spot factor.

Utility model content

The problems such as the utility model provides a kind of precast concrete board-like combination box drain, has solved prior art in prior art and limited by construction plant, and construction quality influence factor is many, and in construction elapsed time is long.

For addressing the above problem, the utility model adopts following technical scheme: the board-like combination box drain of a kind of precast concrete, comprise base plate 2, body of wall 5 and cover plate 8, be equipped with sand cushion 1 in box drain bottom, sand cushion 1 top is placed with base plate 2, on base plate 2 fluted 3, in groove 3 by being connected with body of wall 5 by cement mortar 4, be provided with and carefully protect stone concrete corner protector 6 at body of wall 5 and base plate 2 upper surfaces, body of wall 5 tops are cover plate 8, body of wall 5 is filled and is connected by cement mortar 7 with cover plate 8, forms thus a joint box drain; The bellmouth 10 arranging by two ends on body of wall 5 between every joint box drain is connected with socket 11, base plate 2 and the base plate 2 of every joint box drain, and body of wall 5 and body of wall 5, tamped and be connected by expansive cement 12 between cover plate 8 and cover plate 8.

Advantage of the present utility model: 1, this product is produced in precast yard, quality is not subject to the impact of job site factor; 2, this product is formed, is convenient to transport and installed by four blocks of plates, and construction is fast; 3, on this product base plate, groove is set, make body of wall install after more firm; 4, on this product cover plate, there is stopper, be subject to soil pressure to be difficult for lodging; 5, this product body of wall adopts bayonet joint, safety and firmness.
