Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to the field of rainwater collection and sedimentation technology at construction sites, specifically referring to a rainwater collection and sedimentation device for construction sites. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction. The site where construction work takes place is called the "construction site" or "building site."

[0003] Water accumulation at construction sites can cause muddy ground and affect the construction process, especially in construction sites without drainage facilities. In such cases, rainwater collection and treatment are necessary. However, rainwater carries mud and sand when it flows through the construction site. If it is directly discharged into the surrounding water bodies or soil, it will cause environmental pollution. Therefore, rainwater collection and sedimentation devices are needed at construction sites.

[0004] In existing technology, multiple underground pipes are installed around the construction area, and the multiple underground pipes converge into a single conveying pipe. Rainwater is guided into a sedimentation tank through the conveying pipe for sedimentation. Suspended solids settle at the bottom of the sedimentation tank and can be discharged later. The settled rainwater is then discharged through a discharge pipe.

[0005] However, in actual use, the size of the sedimentation tank is fixed. When there is heavy rainfall and the rainwater flow rate is fast, the residence time of the rainwater in the sedimentation tank is short. Sedimentation requires sufficient time and space for suspended solids to settle. If the rainwater flow rate is too fast, the sedimentation time will be insufficient and the suspended solids will not be fully removed, resulting in poor sedimentation effect.

[0006] Therefore, it is desirable to provide a rainwater collection and sedimentation device for construction sites that can make the suspended solids in rainwater settle more thoroughly without changing the size of the sedimentation tank, thus effectively removing suspended solids and achieving a good sedimentation effect.

[0044] Both the front baffle 5 and the rear baffle 6 are vertically arranged and inclined in the front-to-back direction. Both the front baffle 5 and the rear baffle 6 are located inside the sedimentation tank 1 and above the bottom of the sedimentation tank 1. The front end of the front baffle 5 is located behind the front side wall of the sedimentation tank 1 and is connected to the front side wall of the sedimentation tank 1. The rear end of the rear baffle 6 is located in front of the rear side wall of the sedimentation tank 1 and is connected to the rear side wall of the sedimentation tank 1.

[0052] The rear mounting plate 11 is vertically arranged and positioned along the left-right direction. It is located in front of the rear sidewall of the sedimentation tank 1 and is mounted to the rear sidewall of the sedimentation tank 1 (e.g., by mounting bolts). A rear slot 15 is vertically provided on the front side of the rear mounting plate 11. The width of the slot opening of the rear slot 15 is smaller than the width of the space inside the slot. The upper end of the rear slot 15 is open and located in the top surface of the rear mounting plate 11. The rear end of the rear baffle 6 is vertically inserted... In the rear slot 15, the rear pressure plate 12 is horizontally arranged along the left-right direction and located on the top surface of the rear mounting plate 11. The middle part of the rear pressure plate 12 is located on the upper end of the rear slot 15.

The rear support frame 17 is located in front of and installed on the rear side wall of the sedimentation tank 1, and is located to the right of the rear baffle 6 and abuts against the rear baffle 6. With the above arrangement, when the front baffle 5 and the rear baffle 6 vibrate under the impact of rainwater, the front support frame 16 and the rear support frame 17 respectively support the front baffle 5 and the rear baffle 6, avoiding damage to the front baffle 5 and the rear baffle 6 caused by large water flow impact. With the front baffle 5 having a front drain hole 51 perpendicular to the front baffle 5 and the rear baffle 6 having a rear drain hole 61 perpendicular to the rear baffle 6, the position of the front support frame 16 abutting against the front baffle 5 is offset from the front drain hole 51, and the position of the rear support frame 17 abutting against the rear baffle 6 is offset from the rear drain hole 61. This prevents the front support frame 16 from blocking the front drain hole 51 and the rear support frame 17 from blocking the rear drain hole 61, thereby avoiding affecting the passage of rainwater through the front drain hole 51 and the rear drain hole 61.

[0056] The front support frame 16 and the rear support frame 17 can have any suitable configuration; please refer to [link / reference].

With the above arrangement, when the front baffle 5 and the rear baffle 6 vibrate under the impact of rainwater, the front buffer pad 18 and the rear buffer pad 19 respectively support and dampen the front baffle 5 and the rear baffle 6, thereby further protecting the front baffle 5 and the rear baffle 6. When the front support frame 16 includes a front fixed plate 161, a first front support plate 162 and a second front support plate 163, and the rear support frame 17 includes a rear fixed plate 171, a first rear support plate 172 and a second rear support plate 173, the rear buffer pad 18 is installed at the rear end of the first front support plate 162 and the rear end of the second front support plate 163, and the rear buffer pad 19 is installed at the front end of the first rear support plate 172 and the front end of the second rear support plate 173.

[0062] The front buffer pad 18 and the rear buffer pad 19 can be buffer pads of any suitable material. In a specific embodiment of this utility model, the front buffer pad 18 and the rear buffer pad 19 are both rubber pads.

[0063] The drain outlet 7 can have any suitable shape; please refer to [link / reference]. Figures 1-2 As shown, in a specific embodiment of this utility model, the sewage outlet 7 is elongated and extends along the front-back direction.

[0064] The sedimentation tank 1 can have any suitable shape; please refer to [link / reference]. Figure 1 As shown, in a specific embodiment of this utility model, the sedimentation tank 1 is rectangular.

[0065] The inner bottom surface of the sedimentation tank 1 can be set in any suitable direction; please refer to [link / reference]. Figure 2 As shown, in a specific embodiment of this utility model, the inner bottom surface of the sedimentation tank 1 is arranged along the front-back direction and inclined to the lower left in the direction from right to left.

[0066] The rainwater collection and sedimentation device at the construction site may also include any other suitable components; please refer to [link / reference]. Figures 1-2As shown in a specific embodiment of this utility model, the rainwater collection and sedimentation device at the construction site further includes a stepped sludge plate 20. The stepped sludge plate 20 is horizontally arranged and positioned on the inner bottom surface of the sedimentation tank 1 along the left-right direction and located below the front baffle 5 and the rear baffle 6. The steps of the stepped sludge plate 20 rise gradually from left to right, and the top surface of each step of the stepped sludge plate 20 is arranged along the front-back direction and inclined downwards to the left along the right-left direction. With the above configuration, suspended solids settle on the top surface of the steps of the stepped baffle plate 20. Since the stepped baffle plate 20 is inclined as a whole, the sediments collect at the left end of the sedimentation tank 1. The top surface of the steps of the stepped baffle plate 20 is inclined to the lower left, making it easier for the sediments to fall to the left end of the sedimentation tank 1. At the same time, the stepped shape of the stepped baffle plate 20 prevents the sediments from being pushed to the right end of the sedimentation tank 1 by the impact of the water flow, making it easier to open the sealing cover 4 for discharge later.

[0067] In use, multiple concealed pipes are installed around the construction area to collect rainwater into the inlet pipe 2. The rainwater is then guided into the sedimentation tank 1 through the inlet pipe 2. The drain pipe 3 is located to the right of the inlet pipe 2. As the rainwater flows inside the sedimentation tank 1, the inclined front baffle 5 and rear baffle 6 block the straight-flowing rainwater, thus fixing the internal volume of the sedimentation tank 1 while increasing the flow path of the rainwater. This increases the time that the rainwater stays inside the sedimentation tank 1, resulting in more thorough sedimentation of suspended solids. It also effectively utilizes the area inside the sedimentation tank 1, avoiding the problem of incomplete sedimentation of suspended solids caused by the rapid flow of rainwater during heavy rain. The settled rainwater is finally discharged from the drain pipe 3. The sediment at the bottom of the sedimentation tank 1 can be discharged from the drain outlet 7 by opening the sealing cover 4, allowing for regular cleaning.

[0068] With the sedimentation tank 1 set along the front-to-back direction on the inner bottom surface and tilted downwards and to the left from right to left, the sediment is collected at the left end of the sedimentation tank 1, making it easier to discharge from the drain outlet 7 after the sealing cover 4 is opened.

[0069] Compared with the prior art, the present invention has the following beneficial effects:

[0070] 1. This utility model uses multiple inclined front and rear baffles to block the straight-flowing rainwater, increasing the flow path of the rainwater and allowing it to stay in the sedimentation tank for a longer time. This results in more thorough sedimentation of suspended solids in the rainwater while effectively utilizing the area of ​​the sedimentation tank.

[0071] 2. Based on this, the present invention filters and settles rainwater through the front and rear drain holes, so that when there is a lot of rainwater, the rainwater can pass through the front and rear drain holes and flow directly into the drain pipe for discharge, so that the suspended solids are settled while avoiding flooding caused by excessive rainwater.

[0072] 3. Based on this, the present invention supports the front and rear baffles that vibrate under the impact of rainwater by using the front and rear support frames, and protects the front and rear baffles. If necessary, front and rear buffer pads can also be added for shock absorption.

[0073] 4. Based on this, the present invention uses a stepped baffle plate to collect sediment at the left end of the sedimentation tank, which facilitates subsequent discharge. The stepped shape of the baffle plate also prevents sediment from being swept to the right end of the sedimentation tank by the impact of water flow.

[0074] In summary, the rainwater collection and sedimentation device for construction sites of this utility model can make the suspended solids in rainwater settle more thoroughly without changing the size of the sedimentation tank, and can fully remove suspended solids, thus achieving good sedimentation effect. It has an ingenious design, simple structure, is easy to manufacture, and has low manufacturing cost, making it suitable for large-scale promotion and application.

[0075] Therefore, it is evident that the objective of this utility model has been fully and effectively achieved. The function and structural principles of this utility model have been demonstrated and explained in the embodiments. Without departing from the stated principles, any modifications can be made to the implementation methods. Therefore, this utility model includes all modified embodiments based on the spirit and scope of the claims.
