DETAILED DESCRIPTION

[0016] The application will be further described in detail below in combination with the drawings and the embodiments, but the embodiments should not be understood as limiting the application.

[0017] In order to realize the above-mentioned technology, the present application will be described in detail below in combination with the drawings: The water-containing foundation water treatment device and the manufacturing and using method of the device are suitable for various soils such as clay, sandy soil and silt soil, and can also be used in the soil layer of a beach area in a water-rich area.

[0018] Embodiment 1 The embodiment 1 of the water-containing foundation water treatment device of the present application is composed of the following structures: a metal shell 100 with water-permeable holes, a water-permeable filling core material 200, a water-permeable isolation layer 300 (a water-permeable geotextile layer 300-1 and a metal inner shell 300-2), a stable framework 400, a stable circular ring 601, a radial stable support rod 602, a stable support ring 603 and a drain pipe 800 and the like. The specific structure is shown in the accompanying drawings. Figures 1 to 3 The upper structure of the water-containing foundation water treatment device of the present application is a cylindrical structure, and the bottom is designed as a conical structure with an opening diameter the same as the cylindrical structure. The advantage of this structure design is that the device can be easily inserted into the soil. The metal shell 100 with water-permeable holes in the present application is made of a stainless steel plate. After the steel plate reaches the required size, a punch (not shown in the figure) is used to densely punch small holes on the steel plate, as shown in the accompanying drawings. After rolling, the cylindrical shell and the conical shell of the metal shell 100 are welded and shaped by CO2 gas protection. Figure 4

[0019] The water-permeable filling core material 200 should be filled between the hole-permeable metal shell 100 and the isolation layer 300, so as to filter out the silt and sand in the soil and prevent the device from being blocked.

[0020] The metal inner shell 300-2 in the isolation layer 300 is actually made of a stainless steel plate with a thickness of 1.0 mm, and some holes are densely and uniformly punched on the surface, with a hole diameter of about 0.5-1 mm.

[0021] The stable support ring 603 is the main component for supporting the isolation layer 300, and its strength directly affects the rigidity of the isolation layer 300.

[0022] ​​The stable skeleton 400, the stable circular ring 601, the radial stable support rod 602 and the stable support ring 603 together constitute a stable system inside the isolation layer 300, effectively ensuring the overall rigidity of the isolation layer 300. The stable skeleton 400 is similar in length to the overall length of the water-containing foundation base water treatment device of the present application, is made of a seamless steel pipe with a diameter of φ16-20 mm and a thickness of 0.5-1.5 mm, and in one or more embodiments, the number of stable skeletons 400 is preferably 8. The stable circular ring 601, the radial stable support rod 602 and the stable support ring 603 are all made of HPB235 type smooth round steel bars with a diameter of φ8-12 mm, wherein the diameters of the stable circular ring 601 and the stable support ring 603 match the overall structure of the water-containing foundation base water treatment device of the present application (the overall structure of the present application is the same in diameter as the cylindrical section except for the conical section at the bottom, and since the conical section gradually decreases from top to bottom, in order to ensure that the filling thickness of the water-permeable filling core material 200 remains at 5 cm, the diameters of the stable circular ring 601 and the stable support ring 603 at the conical section are smaller than those at the cylindrical section, and the diameters of the stable circular ring 601 and the stable support ring 603 at the conical section also gradually decrease from top to bottom), so the diameter of the stable circular ring 601 at the conical section should not be too large, and is preferably controlled within 110-140 mm.

[0023] The diameters of various parts of the present application are determined according to the inner diameters at various positions of the water-containing foundation base water treatment device of the present embodiment, and the diameter of the stable support ring 603 is calculated as the difference between the inner diameter of the metal shell 100 and the thickness of the water-permeable filling core material 200 and the thickness of the isolation layer 300. With the stable skeleton 400 made of HPB235 type smooth round steel pipe and the stable support ring 603 made of HPB235 type smooth round steel bar processed into an arc shape by a steel bar bending machine (not shown in the figure), and the stable skeleton 400 and the stable support ring 603 welded and fixed by CO2 gas protection, the main structure of the water-containing foundation base water treatment device of the present embodiment 1 is completed.

[0024] One or two layers of water-permeable geotextile layer 300-1 belonging to the isolation layer 300 are tightly wound outside the stable skeleton 400 and the stable support ring 603 to filter out sludge and other impurities in the water, and the water-permeable geotextile layer 300-1 can be made of general water-permeable geotextile. In addition, the water-permeable geotextile layer 300-1 should be effectively bound and fixed with the stable skeleton 400 to prevent falling off and thus affect the filtering effect.

[0025] Embodiment 2 The present embodiment is basically the same as embodiment 1, and the difference lies in that it further comprises: Referring to Figures 2 to 4The embodiment 2 of the present application further comprises the bearing 1100, the scraper strip 1101, the stop ring 1102, the rotating handle 500, the support structure (the wedge-shaped connecting rod 700 and the rotating fixing mechanism 900).

[0026] The water-permeable filling core 200 is circumferentially and uniformly distributed with a plurality of scraper strips 1101 arranged in the radial direction and protruding on one side of the water-permeable filling core 200. A single scraper strip 1101 is arranged from top to bottom along the water-permeable filling core 200. The protruding side of each scraper strip 1101 abuts against the water-permeable geotextile layer 300-1. The water-permeable geotextile layer 300-1 is gap-fitted with the water-permeable filling core 200. See Figure 5 The water-permeable filling core 200 and the water-permeable isolation layer 300 are both provided with coaxially connected openings at the bottom. The bottom openings are provided with bearings 1100. The outer ring of the bearing 1100 is fixedly connected with the inner wall of the metal shell 100. The bearing 1100 is connected with the water-permeable filling core 200 through the stop ring 1102. The bottom of the metal inner shell 300-2 of the water-permeable isolation layer 300 is inserted into the inner ring of the bearing 1100 and is fixed. The bottom of the bearing 1100 is provided with a support structure fixed with the bottom of the metal shell 100. See Figure 6 The cylindrical shell of the metal shell 100 is circumferentially and uniformly distributed with a plurality of limiting rollers 705 at the top inside. The central axis of each limiting roller 705 is axially parallel to the metal shell 100 and is fixed to the inner wall of the metal shell 100 through a connecting mechanism. The movement surface of the limiting roller 705 is connected with the water-permeable geotextile layer 300-1. The uppermost stable ring 601 of the metal inner shell 300-2 is provided with a rotating handle 500 perpendicular to the ring surface.

[0027] See Figures 7 to 8 The support structure at the bottom of the bearing 1100 comprises a rotating fixing mechanism 900 and a wedge-shaped connecting rod 700 coaxially connected with the rotating fixing mechanism 900. The rotating fixing mechanism 900 comprises a top support 900-2 fixed at the bottom of the bearing 1100 and a bottom support 900-1 fixedly connected with the metal shell 100 and the wedge-shaped connecting rod 700 at the bottom and top, respectively.

[0028] In the embodiment 2 of the water foundation water treatment device of the present application, the bottom support 900-1 is welded to the metal shell 100 as a whole by CO2 gas protection at a certain position from the bottom of the metal shell 100. Since the diameter of the structure of the present application is gradually reduced downwards, the bottom of the stable framework 400 needs to be inserted into the inner ring of the bearing 1100 to rotate relative to the top support 900-2. At this time, the diameter of the top support 900-2 is larger than that of the bottom support 900-1. In order to connect the top support 900-2 and the bottom support 900-1 reliably, a wedge-shaped connecting rod 700 is used to connect them. One end of the wedge-shaped connecting rod 700 with a larger diameter is connected to the top support 900-2, and the other end with a smaller diameter is connected to the bottom support 900-1. The specific connection method is shown in the attached drawings. Figure Four .

[0029] According to the embodiment 2 of the water foundation water treatment device of the present application, it is necessary to rotate the main mechanism when necessary, except for the perforated water-permeable metal shell 100, the scraper strip 1101 and the water-permeable filling core material 200. In order to ensure the normal rotation track, a limiting roller 705 with a height equal to the thickness of the water-permeable filling core material 200 is installed on the top of the metal shell 100, which helps the relative rotation between the rotating mechanism and the water-permeable filling core material 200.

[0030] In this embodiment, the purpose of using the rotating mechanism is that after the water foundation water treatment device of the present application is placed for a period of time, the sand, impurities and other substances in the soil will enter the water foundation water treatment device through the small holes of the metal shell 100, and then adhere to the water-permeable geotextile layer 300-1, which will reduce the water permeability. By setting a rotating mechanism inside the water foundation water treatment device, the sand and impurities adhering to the water-permeable geotextile layer 300-1 are scraped off in a rotating manner, so that the surface of the water-permeable geotextile layer 300-1 remains clean and the water filtration efficiency is improved.

[0031] Embodiment 3 This embodiment is basically the same as embodiment 2, except that it also includes: See Figure 9The water foundation water treatment device disclosed by the embodiment 3 of the present application further comprises an auxiliary mechanism, the auxiliary mechanism shell is the same as the cylindrical segment shell of the metal shell 100, and is provided with the water-permeable filling core 200, the water-permeable isolation layer 300, the stable framework 400, the stable circular ring 601, the radial stable support rod 602, the stable support ring 603 and the scraper strip 1101 which are arranged in the cylindrical segment shell, the water-permeable filling core 200, the water-permeable isolation layer 300, the stable framework 400, the stable circular ring 601, the radial stable support rod 602, the stable support ring 603 and the scraper strip 1101 in the auxiliary mechanism are the same as the structures in the metal shell 100, the inner thread is arranged on the top inner wall of each stable framework 400, the outer thread which is matched with the inner thread is arranged on the bottom outer wall of the stable framework 400 of the auxiliary mechanism to form the butt joint bolt 710, and each stable framework 400 is connected with the stable support ring 603 through the sleeve ring which is tightly matched with the stable framework 400.
