Abstract

The utility model discloses a sand setting rainwater well of a green roof. The sand setting rainwater well of the green roof comprises a roof drain chamber (20) and the rainwater well (22) arranged at the bottom of the roof drain chamber (20); and is characterized in that a sand setting chamber (10) connected with the roof drain chamber is arranged beside the roof drain chamber (20), and a rain grate (12) is covered at the top of the sand setting chamber (10). The sand setting rainwater well of the green roof has the advantages that a twin-well form with sand setting and roof drain discharge arranged separately is adopted; the sand setting well is provided with movable grates so as to facilitate cleaning; and the sand setting chamber and the roof drain chamber are connected through a pipeline higher than the bottoms of the chambers, so that large amount of gravel scoured from the green roof can be effectively isolated and discharged so as to reduce the scour of the gravel on the pipeline.

Description

Greening roof sand setting catch-basin

Technical field

the utility model relates to technical field of buildings, is specifically related to a kind of greening roof sand setting catch-basin.

Background technology

greening roof rain water discharging modes are generally roof drain and directly discharge.And the rainwater on greening roof and the discharging on common roof; Particularly early-stage rainwater has very big-difference; The greening roof since people's activity and torrential rain intensity to the destruction of green soil; Contain more silt in the rainwater, cause the stifled situation of the stasis of blood easily, roof drain and storm sewer are all had very big infringement.Because roof drain is stopped up by silt easily easily, cause daily to all very inconvenience of its maintenance, use.

Summary of the invention

the utility model technical problem to be solved is that the greening roof rain water discharging facility that overcomes prior art is safeguarded, awkward problem, and a kind of roof sand setting catch-basin of shunting deposition silt is provided.

are in order to solve these problems of the prior art; The technical scheme that the utility model provides is: greening roof sand setting catch-basin; The catch-basin that comprises rainwater small room and said rainwater small room bottom; It is characterized in that, also be provided with the sand setting chamber that is attached thereto in that said rainwater small room is other, and top, said sand setting chamber is coated with the rainwater double-edged fine-toothed comb.

preferably, the degree of depth of said sand setting chamber is 145cm ~ 200cm.

preferably, said sand setting chamber is communicated to said rainwater small room through upwards being a pipeline of 10-20 ° with horizontal plane.

preferably, said pipeline is apart from the bottom>=25cm of sand setting chamber.

preferably, said rainwater small room top covers steel deck-plate.

The advantage of the roof sand setting catch-basin of the utility model is: adopt that sand setting and roof drain draining branch be arranged the twin-well form, catch-basin is provided with movable rack, easy cleaning; Sand setting chamber and rainwater small room adopt and are higher than that the dn200 pipeline of 25cm is connected at the bottom of the well chamber, can the sandstone effective isolation that a large amount of roof greening roofings wash away be taken out, to reduce its washing away pipeline; This mode is used in the eliminating of other bigger green roof rainwater equally.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Fig. 1 is the structural representation of the greening roof sand setting catch-basin of the utility model;

Fig. 2 is the A-A generalized section of Fig. 1.

The specific embodiment

further specify such scheme below in conjunction with specific embodiment.Should be understood that these embodiment are used to the utility model is described and the scope that is not limited to limit the utility model.The implementation condition that adopts among the embodiment can be done further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in the normal experiment.

are like the embodiment of the sand setting catch-basin of the utility model of Fig. 1, Fig. 2.

Roof sand setting catch-basin is afforested in , comprises the catch-basin 22 of rainwater small room 20 and said rainwater small room 20 bottoms, and rainwater small room 20 tops cover steel deck-plate 21; Also be provided with the sand setting chamber 10 that is attached thereto in that said rainwater small room 20 is other, and 10 tops, said sand setting chamber are coated with rainwater double-edged fine-toothed comb 12, the degree of depth of said sand setting chamber 10 is 145cm ~ 200cm; Sand setting chamber 10 is communicated to said rainwater small room 20 through upwards being a pipeline 30 of 10-20 ° with horizontal plane, and pipeline 30 is apart from the bottom>=25cm of sand setting chamber 10.

Among embodiment as shown in Figure 2, the outside, plane is of a size of 1950x1000, and flooring sinks to being of a size of 400, and top is fixed according to the height of earthing.Pipeline 30 between two well chambers is not less than 250 for dn200 and 10 shaft bottoms, communicating pipe distance from bottom sand setting chamber; And adopt 15 ° to tilt to catch-basin; Rainwater green roof runoff rainwater and greening infiltration rainwater at first get into the sand setting chamber, and the sandstone of rainwater can be deposited in the bottom of sand setting chamber 10.The good sandstone in the rainwater of place to go in the application, thus alleviated the washing away of pipeline, and the more rainwater water source of high-quality is provided for the rainwater recovery.

sand setting chamber 10 with rainwater small room 20 around adopt angle steel 11 fixing, main body adopts brickwork construction, and the inner face processing of wiping one's face.Usually the earthing on greening roof be not less than according to the rules 1 meter thick, and the roof preferably adopts reinforced concrete structure.

above advantage that shows and described basic principle, principal character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the manual that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.
