Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drainage channel construction, and more specifically to a main channel drainage structure for high groundwater level. Background Art
[0002] Drainage channels are channels (pipes, ditches, etc.) used to collect, transport and discharge rainwater, sewage and wastewater. They are indispensable infrastructure in cities and rural areas and play an important role in ensuring people's lives and environmental sanitation.
[0003] When constructing the main channel of the drainage channel, the groundwater level of the channel line may be higher than the channel bottom plate. It is necessary to drain the groundwater at the bottom of the channel bottom plate in sections before pouring concrete to ensure the normal construction of the channel. The existing water pump extracts and discharges the groundwater, but directly pumping water through the water pump will result in unclean water extraction in the channel, affecting the efficiency of construction during construction. Therefore, a channel drainage structure that can facilitate the extraction of groundwater from the channel bottom plate is needed.
[0004] In view of this, the utility model provides a main channel drainage structure for high groundwater level. Utility Model Content
[0005] The purpose of the utility model is to solve the above-mentioned shortcomings and provide a drainage structure for a main canal with a high groundwater level, which can facilitate the extraction of groundwater from the canal bottom plate.
[0006] The interception weir is used to intercept the groundwater, so that the pumping port can extract the groundwater in the channel that is higher than the channel bottom plate.
[0007] Therefore, the utility model provides a main channel drainage structure for a high groundwater level, comprising a main channel body, a water inlet for extracting groundwater is provided at the bottom of the main channel body, a cut-off component for blocking groundwater is installed on one side of the inner wall of the water inlet, a drainage ditch for the circulation of groundwater is provided at the other end of the inner wall of the water inlet, and a filter component for filtering impurities in the groundwater is installed inside the water inlet.
[0008] As a further improvement of the technical solution, the interception assembly includes a fixed wall adapted to the shape of the inner wall of the main channel body, the outer wall of the fixed wall is provided with an installation groove, and an interception weir plate for intercepting groundwater is fixedly installed inside the installation groove.
[0009] As a further improvement of the technical solution, the filter assembly includes a mounting frame, and a filter mesh groove for filtering groundwater is fixedly installed on the inner wall of the mounting frame.
[0010] As a further improvement of the technical solution, two intercepting weir plates are provided, and the two intercepting weir plates intercept the groundwater in the middle water pumping port and the drainage ditch.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] The invention is used in the drainage structure of the main canal with high groundwater level. An intercepting weir is arranged on one side of the inner wall of the water pumping port to face the outside of the water pumping port, and another intercepting weir is arranged 500 meters away from the water pumping port to intercept the groundwater in the middle area, so that the staff can use the sewage pump to extract the groundwater above the canal bottom plate through the water pumping port. The drainage ditch opened at another place on the inner wall of the water pumping port can circulate the groundwater above the canal bottom to prevent the groundwater from flowing to the bottom of the excavated canal inner wall. The drainage ditch can also judge the height of the groundwater. The excavation depth of the drainage ditch is the same as the depth of the canal bottom that needs to be excavated. When the groundwater in the drainage ditch is completely extracted by the sewage pump in the water pumping port, it can be judged that the groundwater above the canal bottom has been extracted.

[0019] When constructing the main channel of the drainage channel, the groundwater level of the channel line may be higher than the channel bottom plate. It is necessary to drain the groundwater at the bottom of the channel bottom plate in sections before pouring concrete to ensure the normal construction of the channel. The existing water pump extracts and discharges the groundwater, but directly pumping water through the water pump will result in unclean water extraction in the channel, affecting the efficiency of construction during construction. Therefore, a channel drainage structure that can facilitate the extraction of groundwater from the channel bottom plate is needed.
[0020] like Figure 1-2As shown, the device includes a main channel body 1, a water inlet 2 for extracting groundwater is opened at the bottom of the main channel body 1, a cut-off component 3 for blocking groundwater is installed on one side of the inner wall of the water inlet 2, a drainage ditch 4 for the circulation of groundwater is opened at the other end of the inner wall of the water inlet 2, and a filtering component 5 for filtering impurities in the groundwater is installed inside the water inlet 2.
[0021] The intercepting component 3 is arranged on one side of the inner wall of the water pumping port 2 to intercept the groundwater outside the water pumping port 2, so that the staff can use the sewage pump to extract the groundwater above the channel bottom plate through the water pumping port 2. The drainage ditch 4 opened at another place on the inner wall of the water pumping port 2 can circulate the groundwater above the channel bottom to prevent the groundwater from flowing to the bottom of the excavated channel inner wall. The drainage ditch 4 can also judge the height of the groundwater. The excavation depth of the drainage ditch 4 is the same as the depth of the channel bottom that needs to be excavated. When the groundwater in the drainage ditch 4 is completely extracted by the sewage pump in the water pumping port 2, it can be judged that the groundwater above the channel bottom has been completely extracted.
[0022] First, the specific structure of the interception component 3 is disclosed. The interception component 3 includes a fixed wall 301 adapted to the shape of the inner wall of the main channel body 1. The outer wall of the fixed wall 301 is provided with an installation groove, and an interception weir plate 302 for intercepting groundwater is fixedly installed inside the installation groove.
[0023] Two intercepting weir plates 302 are provided, and the two intercepting weir plates 302 intercept the groundwater in the middle water pumping port 2 and the drainage ditch 4 .
[0024] By installing two intercepting weir plates 302 through fixed walls 301 every 500 meters in the channel to be constructed, the groundwater within 500 meters of the area is intercepted, and the groundwater is extracted through the pumping port 2. After the groundwater extraction within 500 meters of the section is completed, the intercepting weir plates 302 are installed every 500 meters, and then the pumping port 2 is opened to extract the groundwater in the area, so as to achieve the effect of facilitating the extraction of groundwater by intercepting the groundwater. When the groundwater extraction of the entire canal is completed and construction is carried out, the intercepting weir plates 302 can be removed.
[0025] The improvement of this embodiment is that: the interception weir plate 302 structure is used to intercept the groundwater in the area, solving the problem of the inability to extract the groundwater at the bottom of the channel cleanly in the prior art;
[0026] When the water inlet 2 in the prior art is dug, the groundwater at the water inlet 2 will be mixed with dirt and other debris, resulting in low efficiency of the sewage pump in extracting groundwater. Figure 3 A second embodiment of the present utility model is shown.
[0027] The specific structure of the filter assembly 5 is disclosed again. The filter assembly 5 includes a mounting frame 501, and a filter mesh groove 502 for filtering groundwater is fixedly installed on the inner wall of the mounting frame 501.
[0028] The mounting frame 501 is installed on the inner wall of the water pumping port 2 by welding. The filter screen slot 502 of the mounting frame 501 is in a slot shape and immersed in the groundwater. The water pumping pipe port is placed in the filter screen slot 502. The filter screen slot 502 can filter the groundwater entering the water pumping pipe to prevent foreign matter from entering and clogging the sewage pump.
[0029] In summary, the working principle of this solution is as follows:
[0030] A weir plate 302 is arranged on one side of the inner wall of the water pumping port 2 to face the outside of the water pumping port 2, and another weir plate 302 is arranged 500 meters away from the water pumping port 2 to intercept the groundwater in the middle area, so that the staff can use the sewage pump to extract the groundwater above the channel bottom plate through the water pumping port 2. The drainage ditch 4 opened at another place on the inner wall of the water pumping port 2 can circulate the groundwater above the channel bottom to prevent the groundwater from flowing to the bottom of the excavated channel inner wall. The drainage ditch 4 can also judge the height of the groundwater. The excavation depth of the drainage ditch 4 is the same as the depth of the channel bottom that needs to be excavated. When the groundwater in the drainage ditch 4 is completely extracted by the sewage pump in the water pumping port 2, it can be judged that the groundwater above the channel bottom has been extracted.
[0031] By installing the mounting frame 501 on the inner wall of the water pumping port 2 by welding, the filter screen slot 502 of the mounting frame 501 is in a slot shape and immersed in the groundwater. The water pumping pipe port is placed in the filter screen slot 502, so that the filter screen slot 502 can filter the groundwater entering the water pumping pipe to prevent foreign matter from entering and clogging the sewage pump.
[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
