Description

Technical Field

[0002] With the rapid development of urban construction and the decreasing construction land, the impact of buildings, roads, municipal pipelines, underground structures, etc. around deep foundation pits on the construction of precipitation pipe wells is becoming more and more significant. The on-site working space often cannot meet the requirements of precipitation well construction, so it is necessary to use local precipitation inclined well structures.

[0003] According to the Chinese patent with the authorized publication number CN212561582U, a dewatering inclined well in a deep foundation pit is disclosed. By making full use of the lower space around the deep foundation pit and adopting an inclined dewatering pipe diameter, the problem of insufficient surface construction space is solved. When the above scheme is actually used, since the construction of the inclined well is different from that of the ordinary vertical pipe, there is a certain angle between the direction of the inclined well and the direction of gravity. When the well pipe is installed, the filter wrapped around the outside of the well pipe is prone to friction with the well wall, which may cause the filter to be scratched, etc., thereby affecting the quality of the local dewatering inclined well and reducing the practicality of the existing dewatering inclined well.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0029] See also Figure 1-3The utility model provides a technical solution: a local dewatering inclined well structure, comprising a pipe body 1, wherein a water filter assembly 200 for filtering groundwater is installed inside the pipe body 1, and a fixing assembly 300 for splicing and fixing the pipe body 1 is installed outside the pipe body 1. Through the coordinated use of the pipe body 1, the sealing well section 2, the conical block 3, the water filter assembly 200 and the fixing assembly 300, when the well pipe is installed at a local position of the construction site, it can effectively avoid the friction between the filter screen wrapped around the outside of the well pipe and the well wall due to a certain angle between the inclined well direction and the gravity direction, thereby effectively avoiding the filter screen from being scratched, etc., thereby ensuring the well quality of the local dewatering inclined well, and at the same time, it can also facilitate the assembly of the well pipe, thereby improving the practicality of the local dewatering inclined well structure.

[0030] In this embodiment, the water filter assembly 200 is a structure for filtering groundwater.

[0031] like Figure 1 , Figure 2 and Figure 3 The water filter assembly 200 shown includes two annular grooves 201 respectively opened at the top and bottom of the tube body 1, two arc blocks 202 are slidably connected inside the annular grooves 201, an installation groove 203 is opened inside the tube body 1, an annular filter screen 204 is fixedly connected inside the installation groove 203, a filling cavity 205 is opened inside the tube body 1, and a plurality of through holes 206 are opened on the outside of the tube body 1.

[0032] It should be noted that the filling cavity 205 is filled with gravel with a particle size of 3 to 7 mm. Through the coordinated use of the through hole 206, the annular filter screen 204 and the filling cavity 205, the filter screen is effectively prevented from being scratched, ensuring the correct and effective filtration of groundwater and preventing the local precipitation inclined shaft structure from being contaminated by sand and soil particles.

[0033] In addition, the side of the installation groove 203 away from the through hole 206 is connected to the side of the filling cavity 205 away from the through hole 206, and the sides of multiple through holes 206 close to the filling cavity 205 are all connected to the filling cavity 205, ensuring that groundwater can enter the filling cavity 205 through the through hole 206, ensuring that groundwater passes through the through hole 206, the annular filter net 204 and the filling cavity 205 in sequence to enter the interior of the pipe body 1.

[0034] In addition, a sealing section 2 is fixedly connected between the tops of the two top arc blocks 202, and a conical block 3 is fixedly connected between the bottoms of the two bottom arc blocks 202. The pipe body 1, the sealing section 2 and the conical block 3 are installed respectively. The conical block 3 can effectively reduce the resistance of the pipe body 1 when entering the inclined well.

[0035] At the same time, the distance between the top of the top through hole 206 and the bottom of the bottom through hole 206 is smaller than the height of the annular filling cavity 205, ensuring that the through hole 206 can effectively transport groundwater.

[0036] In this embodiment, the fixing assembly 300 is a structure for splicing and fixing the local dewatering inclined shaft structure.

[0037] like Figure 1 and Figure 3 As shown, the fixing assembly 300 includes four fixing frames 301 respectively fixedly connected to the left and right sides of the tube body 1, the inside of the fixing frame 301 is fixedly connected with a spring 302, the opposite sides of the left and right springs 302 are fixedly connected with a slider 305, the inside of the slider 305 is fixedly connected with a plug rod 304, the end of the plug rod 304 away from the tube body 1 is fixedly connected with a pull block 303, two slide grooves 306 are provided on the left and right sides of the tube body 1, and a plug hole 307 is provided on the left side of the arc block 202.

[0038] It should be noted that the slider 305 is slidably connected to the inside of the slide groove 306, the width of the slider 305 is equal to the width of the slide groove 306, ensuring that the slider 305 slides more stably in the slide groove 306, the width of the slider 305 is equal to the width inside the fixed frame 301, and the height of the slider 305 is equal to the height inside the fixed frame 301, ensuring that the slider 305 can slide more stably in the fixed frame 301.

[0039] In addition, the opposite ends of the left and right side connecting rods 304 pass through the fixed frame 301, the slide groove 306, the slider 305, the tube body 1, the annular groove 201 and the arc block 202 in sequence and extend to the interior of the arc block 202 to connect with the connecting hole 307, ensuring that the connecting rod 304 can fix the arc block 202 through the connecting hole 307, thereby fixing the sealing section 2 and the conical block 3.

[0040] In addition, a triangular block is fixedly connected to the bottom of the fixed frame 301 to facilitate the fixed frame 301 to enter the inclined shaft.

[0041] The working principle of the above embodiment is:

[0042] Before use, first pull the pull block 303 to the left and right sides, thereby driving the connecting rod 304 to move left and right, so that the connecting rod 304 is separated from the annular groove 201. At this time, the spring 302 is in a compressed state, and then the sealing section 2 and the conical block 3 are spliced ​​and installed with the pipe body 1 through the annular groove 201 and the arc block 202, and then the pull block 303 is released. Under the action of the restoring elastic force of the spring 302, the connecting rod 304 returns to its original position, so that the connecting rod 304 is plugged into the arc block 202 through the plug hole 307, thereby installing and fixing the conical block 3 and the pipe body 1, and then the conical block 3 is used to put the pipe body 1 into the precipitation inclined well respectively, and then the through hole 206, the filling cavity 205 and the annular filter net 204 can ensure that the groundwater enters the precipitation inclined well, and at the same time effectively prevent sand or soil particles in the groundwater from entering the precipitation inclined well.

[0043] Compared with the prior art, the local dewatering inclined well structure, through the coordinated use of the pipe body 1, the well sealing section 2, the conical block 3, the water filtering assembly 200 and the fixing assembly 300, can effectively avoid the friction between the filter screen wrapped around the outside of the well pipe and the well wall due to the certain angle between the inclined well direction and the gravity direction when the well pipe is installed at a local position of the construction site, thereby effectively avoiding the filter screen from being scratched, etc., thereby ensuring the well quality of the local dewatering inclined well. At the same time, it can also facilitate the assembly of the well pipe, improve the practicability of the local dewatering inclined well structure, and solve the problem of low practicability of the existing dewatering inclined wells.
