Description

Chemical plant area rainwater open ditch with sand collection function

Technical Field

The utility model relates to the technical field of drainage ditches, in particular to a rainwater open ditch with a sand collecting function for a chemical plant area.

Background

Various chemical industry parks require that factory rainwater systems adopt the open drain of rainwater to collect, discharge, and the fretwork apron is adopted so that the inspection of patrolling in the top accomplishes that "the open drain of rainwater does not have the rainwater" prevents to steal and arrange the wrong row of waste water of production.

At present, the open rainwater ditches in various places are made with reference to a national building standard design drawing set J331, J332, G221 ditches and cover plates, the drawing set has a simple U-shaped structure and has no functions of sand collection and convenient dredging, silt, leaves and the like on roads are easy to enter the rainwater ditches along with rainwater washing and deposit, a plant area with a large area is provided, the width of the rainwater ditches exceeds 1 meter, the depth of the rainwater ditches exceeds 2 meters, the dredging is difficult and has certain operation danger, the deposition time is long, the drainage of the ditches is not smooth, and the sludge fermentation is smelly to influence the discharged water quality index, thereby bringing great troubles to enterprises.

SUMMERY OF THE UTILITY MODEL

Aiming at the problems mentioned in the background technology, the utility model provides the open rainwater ditch with the sand collecting function in the chemical plant area, so that the accumulation and the silt of the existing open rainwater ditch are reduced, and meanwhile, the dredging is convenient.

In order to achieve the purpose, the utility model adopts the following technical scheme:

a chemical plant area rainwater open ditch with sand collection function comprises: the main rainwater ditch, the angle iron, the first grid cover plate, the second grid cover plate, the sand collecting pit, the water passing hole and the filter screen are arranged, the sand collecting pit is arranged on one side of the road and flush with the road surface, the second grid cover plate covers the sand collecting pit, and the main rainwater ditch is higher than the road surface and is connected with the sand collecting pit through the water passing hole. The filter screen is arranged in the water through hole.

In order to prevent the sand collecting pits from faults and improve the drainage efficiency of the pavement, the utility model provides another preferable scheme, wherein the sand collecting pits comprise a plurality of sand collecting pits which are distributed at intervals along the main rainwater ditch, and the distance between the sand collecting pits is 30 m.

In order to ensure that the sand discharge function operates normally, the utility model provides another preferable scheme that the depth of the sand trap is not more than 700mm and is shallower than the main rainwater ditch.

In order to facilitate subsequent cleaning personnel to clean sludge in the sand collecting pit, the utility model provides another preferable scheme, and the bottom surface of the sand collecting pit is in a plane or hemispherical surface shape.

In order to provide a simple and reliable connection mode, the utility model provides another preferable scheme that the water through holes are horizontally arranged, and the cross section of the water through holes is rectangular or circular.

In order to filter floating objects such as leaves entering the sand collecting pit, the utility model provides another preferable scheme, and the filter screen is made of stainless steel and is arranged at the inlet of the water through hole.

In general, compared with the prior art, the above technical solution contemplated by the present invention can achieve the following beneficial effects:

the main rainwater ditch of the utility model is higher than the road surface, which not only can replace the curbstone of the traditional road, but also can prevent the rainwater on the road surface from wrapping up and carrying the sundries such as silt, leaves and the like to directly enter the main rainwater ditch; a sand collecting pit is arranged on one side of the main rainwater ditch road, and when rainwater is collected on the road, the rainwater firstly flows into the sand collecting pit and settles silt to the bottom of the pit in the sand collecting pit. When the height of the water surface in the sand collection pit exceeds the bottom surface of the water through hole, the accumulated water overflows through the water through hole and enters the main rainwater ditch tunnel, and meanwhile, a filter screen is arranged on one side of the water through hole sand collection pit to intercept the floaters such as leaves in rainwater and the like to enter the main rainwater ditch. Debris such as silt, leaves and the like are collected through the attached sand collecting pit, so that the open ditch sedimentation condition of rainwater is relieved; in addition, the depth of the sand collecting pit is small, the cover plate is small in size and light in weight, the difficulty in cleaning is reduced, potential safety hazards in operation are eliminated, and the maintenance cost is saved.

Detailed Description

The following detailed description of the present invention, in conjunction with fig. 1, will make it clear for those skilled in the art how to practice the present invention. While the utility model has been described in connection with preferred embodiments thereof, these embodiments are merely illustrative, and not restrictive, of the scope of the utility model.

Example 1

Referring to fig. 1, a rainwater open ditch with sand collecting function for chemical plant area includes: the device comprises angle iron, a first grid cover plate, a main rainwater ditch, a sand collecting pit, a second grid cover plate, a water through hole and a filter screen.

The main rainwater ditch is close to the road side and is additionally provided with a sand collecting pit which is parallel and level to the road surface, and the main rainwater ditch is 150mm higher than the road surface.
