Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

The utility model provides a gutter inlet, includes curb 1, water drainage tank 2, and road surface 3 and water drainage tank 2 are located the both sides of curb 1 respectively, water drainage tank 2's bottom is connected with branch pipe 4, be equipped with between curb 1 and the water drainage tank 2 and sink mud groove 5, sink mud groove 5's top the top of water drainage tank 2 all is equipped with rainwater comb 6, install below the rainwater comb of water drainage tank 2 and cut dirty frame 12.

The kerbstone 1 is a hollow kerbstone. Be equipped with the through-hole on the curb 1, 3 one sides on the road surface and the 2 one sides intercommunication of water drainage tank of intercommunication curb 1, the rainwater can pass through the through-hole flows.

When raining, the rainwater falls on road surface 3, can flow to the both sides on road surface 3 based on the flashing to through-hole runner silt basin 5 department on curb 1.

The mud groove 5 is embedded into a green land 14 which is a sinking green land, and the height of the top surface of the mud groove 5 is lower than that of the top surface of the drainage groove 2, namely the height of the rain grate 6 on the mud groove 5 is lower than that of the rain grate 6 of the drainage groove 2.

After rainwater flows through the curb 1, solid-liquid separation can be carried out at the mud groove 5, and based on the density difference of solid silt and rainwater, the solid silt sinks to the mud groove 5, and the rainwater overflows to the drainage channel 2.

The difference in height design of water drainage tank 2 and mud groove 5 is in order to reduce the velocity of flow of rainwater, avoids because the velocity of flow of rainwater is too fast directly to erode silt to water drainage tank 2 and goes out, increases the effect of subsiding, and the size of its difference in height can be according to the rainfall adjustment in installation area.

Meanwhile, the drainage channel 2 is used as an overflow port, and after a certain amount of water is stored in the green space 14, the water overflows through the drainage channel 2, so that the height of the drainage channel 2 is always the highest among all facilities in the opening of the first kerbstone 1.

2 lateral walls of water drainage tank inlay in the lateral wall of mud groove 5 has reinforcing bar 8, pours into in water drainage tank 2, mud groove 5 when filling with the rainwater, and its inside hydraulic pressure is very big, causes the fracture of pipe wall easily, needs the reinforcing bar to consolidate, 8's of reinforcing bar quantity is a plurality of, include the bar reinforcing bar of placing along the horizontal direction and along the U-shaped reinforcing bar of vertical direction placing, wholly form netted reinforcing bar net, increase water drainage tank 2, mud groove 5's lateral wall intensity.

The edge of rainwater comb 6 is equipped with lifting hook 9, lifting hook 9 is for buckling the reinforcing bar that is "T" shape structure, the lower part of lifting hook 9 is buried in rainwater comb 6, the upper portion of lifting hook 9 is annular lewis hole.

And embedded angle steel 10 is arranged between the mud settling tank 5 and the drainage tank 2, and the embedded angle steel 10 is used for fixing, so that rainwater is prevented from directly impacting the rainwater grate 6 of the drainage tank 2, and the rainwater grate is prevented from displacing.

Plain concrete 7 is poured at the joint of the branch pipe 4 and the drainage channel 2. The underground space for installing the rainwater inlet is of an L-shaped structure, the horizontal edge of the underground space is used for installing the drainage channel 2, the vertical edge of the underground space is used for installing the branch pipe 4, and after the underground space is installed, in order to avoid rainwater from penetrating into the L-shaped space, the underground space needs to be sealed in a concrete pouring mode.

And a gravel cushion layer 13 is arranged at the bottom of the drainage channel 2, and the gravel cushion layer 13 is positioned below the branch pipe 4.

An overflow hole 11 is arranged between the drainage groove 2 and the sludge settling groove 5.

The overflow holes 11 do not work when raining, the function of the overflow holes is that after the raining stops, if the overflow holes 11 do not exist, water can be deposited above the sludge settling tank after the raining stops, the overflow holes 11 can sink quickly when meeting water, and water is prevented from being accumulated above the sludge settling tank 5.

Above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical personnel probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
