Abstract

FIELD: flood water draining systems. SUBSTANCE: this relates to settlers, flood water collectors and other devices for rain water draining. Rain water collecting pit has body with trash catching grate secured to it, incline guide strip installed inside body directly under trash catching grate, vertical partition which divides body into water collecting and settling chambers, water overflow opening made in partition and communicating with water collecting and settling chambers, removable dirt collector installed in bottom part of settling chamber, and water outflow pipe. Device effectively catches large, medium and fine inclusions which prevents clogging of sewerage systems and prolongs their service life, is also reliable and convenient in usage. EFFECT: high efficiency. 1 dwg

Description

 The invention relates to sedimentation tanks, stormwater and other devices intended for drainage of storm water.

 Known storm water inlet, including a chamber, grate and a well / 1 /.

 The disadvantage of this device is the low efficiency.

 The closest to the technical nature and the achieved result is a storm water inlet including a casing, a trash-holding grate mounted on it, located in the upper part of the casing, an inclined guide plate installed inside the casing directly below the trash-holding grating, a vertical partition dividing the casing into a plumbing and settling chamber, a drainage hole made in the partition and connected with the intake and settling chambers, a removable dirt collector and a drainage pipe boo / 2 /.

 The disadvantage of this device is the low efficiency of the removal of large solid inclusions, as well as the unreliability in operation.

 The drawing shows a section of a well. The storm water inlet includes a housing 1, a trash holding grate 2 mounted on it, an inclined guide plate 3 installed inside the housing 1, directly below the trash holding grating 2, a vertical partition 4 dividing the housing into a water inlet 5 and a settling chamber 6, a drainage hole 7 made in the partition 4 and communicating with the intake 5 and settling 6 chambers, a removable dirt collector 8 installed in the bottom of the settling chamber 6 and the drainage pipe 9.

 The well is equipped with a waste tray 10 located parallel to the side wall of the housing 1 and its upper edge adjacent to the lower end face of the trash guard 2, the guide plate 3 being made waterproof and the trash guard 2 pivotally fixed relative to the upper end face of the housing 1.

 The presence of the waste tray 10 allows you to autonomously divert large inclusions that are entrained by the storm drain, i.e. cut them off from the bulk of the flow entering the well. The guaranteed removal of large inclusions is facilitated by the inclined bow position of the trash guard 2, as well as the end connection of the tray 10 with the lower face of the grill 2.

 The implementation of the inclined guide plate 3 waterproof allows, in turn, guaranteed to divert the flow of water entering the well, the inclusion of medium and small size in the settling chamber 6, which contributes to the inclined position of the plate 3.

 The swivel connection of the trash guard 2 relative to the upper side face of the housing 1 allows you to quickly dismantle the removable dirt collector 8 in order to clean it from sediment, as well as other preventive work.

 The implementation of the dirt collector 8 waterproof allows, using the "false bottom" of the settling chamber 6, to remove all sediment from the well. In general, all the elements of the proposed solution are aimed at improving the efficiency and reliability in the operation of this device.

 The storm water well works as follows.

 Surface wastewater, passing through the grate 2, flows down an inclined plate 3 into a settling chamber 6, entraining inclusions (pumps) of medium and small fractions. Large inclusions are rolled along the grate 2, fall on the waste tray 10 and no longer participate in the total mass of stormwater runoff.

 The dimensions of the settling chamber, the depth of the water in it, as well as the hydraulic flow pattern, contribute to the deposition of a large part of the sediment removable dirt collector 8.

 The flow of sediment-free water through the spillway 7 enters the water-intake chamber 5, separated by a partition 4 from the settling chamber 6, and then goes through the discharge pipe 9 to the rainwater drainage network.

 In case of critical filling, the sump 8 is removed from the housing 1.

 The proposed device will allow, unlike known devices, to effectively delay large, medium and small inclusions, which will prevent clogging of the rainwater drainage network and extend its service life.

Claims (1)
