Description

Technical Field

[0001] The utility model relates to the technical field of related equipment for intercepting and draining ditches, in particular to a grit chamber and a water intercepting structure. Background Art

[0002] A grit chamber is an important part of a small-scale water storage, drainage, diversion and irrigation project. It is generally built at the intersection of two canals, where the canal water enters the chamber, or at the end of the canal, playing the roles of sand and soil interception, energy dissipation and erosion prevention, sedimentation, and water clarification.

[0003] In the prior art, during the construction related to mountain slopes, to avoid geological disasters such as landslides and collapses on the slopes caused by rainfall affecting the construction, a drainage structure is often set along the slope gradient at the construction site for drainage, so as to reduce the scouring of rainwater and the seepage of surface water, which may lead to the loosening of the slope soil and thus reduce the slope stability, and further cause disasters such as landslides and collapses.

[0004] Most common slope drainage structures mostly include intercepting and draining ditches set along the mountain terrain to intercept and drain the surface water and rainfall within the catchment area of the surrounding mountain slopes, reducing the scouring of rainwater and the seepage of surface water, which may lead to the loosening of the slope soil and thus reduce the slope stability, resulting in situations such as landslides and collapses; at the same time, to avoid that when the rainfall is large, the rainwater scouring is likely to carry sand, debris, etc. on the ground into the intercepting and draining ditches, causing blockage at the connection between the intercepting and draining ditches and the natural ditch channels and reducing the drainage rate, a grit chamber is often set at the end of the intercepting and draining ditches.

[0005] When the construction period of the project on the mountain slope is short, in order to ensure that the natural environmental changes caused by the construction reconstruction can be restored after the construction is completed, a temporary grit chamber is often used; in the existing temporary grit chamber, when the water level in the chamber is high and the water flow is large, a large amount of sediment will flow into the grit chamber along with the water flow and directly flow into the downstream drainage ditch without time to settle, resulting in poor sedimentation effect of the grit chamber and causing blockage of the downstream drainage ditch and other situations. Summary of the Utility Model

[0042] Embodiment 1

[0043] This embodiment provides a grit chamber. Referring to Figure 1 , this grit chamber includes a grit chamber body 1, a water inlet assembly 2, and a water outlet part 3. One end of the grit chamber body 1 is connected to the water inlet assembly 2, and the other end is connected to the water outlet part 3; a water retaining wall 11 is arranged in the grit chamber body 1 along a first direction, and the water retaining wall 11 is used to separate the internal space of the grit chamber body 1; a gap for water flow is formed between the water retaining wall 11 and the inner wall on one side of the grit chamber body 1.

[0044] The embodiment of the present utility model at least alleviates the technical problem in the prior art that due to excessive water flow driving a large amount of sediment to scour, the downstream drainage ditch is blocked.

[0045] In the embodiment of the present utility model, a water inlet assembly 2 and a water outlet part 3 are respectively arranged at both ends of the grit chamber body 1, and preferably, the water inlet assembly 2 and the water outlet part 3 are respectively arranged at both ends of the grit chamber body 1, so that after the water containing sediment enters the grit chamber body 1, it can have a longer travel, which helps the water to precipitate the sediment during the flowing process; and by setting the water retaining wall 11, not only can the water flow speed be slowed down, but also a certain amount of sediment can be blocked to a certain extent.

[0046] Compared with the prior art, the grit chamber provided by the embodiment of the present utility model sets a water retaining wall 11 in the grit chamber body 1, so that the water containing sediment can be decelerated in the grit chamber body 1, and then more sediment can precipitate, and the water retaining wall 11 can also block a large amount of sediment from flowing through, thus achieving a better effect on the sediment settlement and filtration.

[0047] In an optional implementation manner of this embodiment, referring to Figure 1 or Figure 2 , there are multiple water retaining walls 11, and the multiple water retaining walls 11 are spaced apart in the grit chamber body 1 along a second direction, and an included angle is provided between the second direction and the first direction.

[0048] Specifically, a plurality of water retaining walls 11 are spaced apart along the second direction within the grit chamber body 1. Preferably, the water retaining walls 11 are perpendicular to the inner side wall of the grit chamber body 1, and there is a gap between the water retaining walls 11 and the side wall on the other side. The plurality of water retaining walls 11 are used to decelerate the water flow multiple times to help the sediment in the water flow settle at the bottom of the pool.

[0049] Further, referring to Figure 1 or Figure 2 , among the plurality of water retaining walls 11 distributed along the second direction, the corresponding water retaining walls 11 in the odd positions are connected to the first inner wall of the grit chamber body 1; the remaining water retaining walls 11 are connected to the second inner wall of the grit chamber body 1; the first inner wall and the second inner wall are distributed opposite to each other.

[0050] Specifically: The water retaining walls 11 are spaced apart along the second direction, and the water retaining walls 11 in the odd positions are all connected to the inner wall on the first side of the grit chamber body 1 and have a gap with the inner wall on the second side; the corresponding water retaining walls 11 in the even positions are connected to the inner wall on the second side and have a gap with the inner wall on the first side. Thus, a serpentine water flow channel is formed within the grit chamber body 1, effectively improving the water flow deceleration effect and the effect of blocking sediment.

[0051] Further, referring to Figure 1 , the water inlet assembly 2 includes a water inlet part 21 and a baffle 22. The water inlet part 21 is connected to the pool wall of the grit chamber body 1, and the water inlet part 21 is used to connect to an external flowing water pipeline; the baffle 22 is connected to the water inlet part 21, and the baffle 22 is used to block the water flow flowing out of the water inlet part 21 to slow down the water flow.

[0052] Specifically: The baffle 22 is connected to the water inlet part 21, and there is a certain inclination angle between the baffle 22 and the water inlet part 21. Thus, the baffle 22 can be used to initially limit the speed of the water flow flushing out of the water inlet part 21, so that the water flow decelerates when entering the grit chamber body 1. Preferably, the baffle 22 preferably inclines towards the direction of the grit chamber body 1.

[0053] Further, referring to Figure 1 , the baffle 22 is provided with an arc-shaped structure, and the concave surface of the arc-shaped baffle 22 faces the grit chamber body 1.

[0054] Specifically: The baffle 22 is provided with an arc-shaped structure, and the width of the arc-shaped baffle 22 is not less than the width of the water inlet part 21 to prevent the water flow from overflowing from both sides of the baffle 22. The arc-shaped baffle 22 can effectively guide the water flow and facilitate the water flow to enter the grit chamber body 1 at a certain speed.

[0055] Further, referring to Figure 1 , the baffle 22 includes an elastic arc-shaped plate, and the elastic arc-shaped plate is connected to the pool wall of the grit chamber body 1.

[0056] Specifically, the baffle 22 includes an elastic arc-shaped plate, which can effectively offset the impact of the water flow through its own elasticity, preventing the water flow from splashing out after hitting the baffle 22.

[0057] Embodiment 2

[0058] This embodiment provides a grit chamber. Refer to Figure 2 , the grit chamber body 1 is provided with steps 12, the steps 12 are connected to the bottom of the grit chamber body 1, and the steps 12 are arranged between adjacent retaining walls 11.

[0059] Specifically: the steps 12 are connected to the bottom of the grit chamber body 1, and the steps 12 are arranged between adjacent retaining walls 11; during use, when the water flows through the steps 12 step by step, since the sediment is located below the water, the upper layer of water flows through the steps 12, while the lower layer of sediment is blocked by the steps 12, thereby achieving the effect of filtering out the sediment.

[0060] It should be noted that the steps 12 can also enable small animals (such as squirrels or rabbits, etc.) that accidentally enter the grit chamber body 1 to escape, preventing the small animals from drowning in the water, protecting the animals while avoiding the growth of germs due to water pollution.

[0061] Furthermore, refer to Figure 2 , the steps 12 are gradually raised along the water flow direction, and the top height of the steps 12 is lower than the height of the retaining wall 11.

[0062] Specifically: the steps 12 are gradually raised along the water flow direction, and the highest end of the steps 12 is lower than the top height of the retaining wall 11, thereby enabling the water flow to be gradually raised when passing through the steps 12, so that the sediment located below the water flow is blocked by the steps 12, and then the water flow passes through the highest point of the steps 12.

[0063] In an alternative implementation manner of this embodiment, refer to Figure 1 or Figure 2 , the grit chamber body 1 is set as a cuboid structure; the water inlet assembly 2 is connected to the pool wall at a corner of the grit chamber body 1; the water outlet part 3 is connected to the pool wall at the diagonal corner of the water inlet assembly 2.

[0064] Specifically: the grit chamber body 1 is set as a cuboid structure, and preferably, the water inlet assembly 2 and the water outlet part 3 are respectively arranged on two opposite long sides of the grit chamber body 1, and the water inlet assembly 2 and the water outlet part 3 are distributed along the diagonal of the rectangle, so that the water flow can have a longer travel distance during the process of flowing through the grit chamber body 1.

[0065] Embodiment 3

[0066] This embodiment provides a water intercepting structure, which includes the grit chamber provided by any optional implementation manner in Embodiment 1.

The specific structure and the achievable effects can be obtained by referring to the optional or preferred implementation manners in the first embodiment.

The same or similar parts among the embodiments can be referred to each other. The above embodiments in this specification are only used to illustrate the technical solutions of the present invention, rather than to limit them.
