[0030] Next,Figs. 1-4 The reusable pipe well device with water level monitoring function is described in detail.

[0031] As Figs. 1-4 shown, the reusable pipe well device with water level monitoring function comprises a mouth sealing assembly 1, a barrel 3 and a water level detector 8. The mouth sealing assembly 1 is arranged at the well mouth of the dewatering pipe well and comprises a pipe body 11, a blocking plate arranged inside the pipe body 11, a water stop wing ring 15 welded at the middle position of the outer part of the pipe body 11 and extending into the bottom plate concrete 2, and a base 14 welded at the bottom end of the pipe body 11 and buried below the foundation cushion layer of the well mouth.

[0032] The pipe body 11 is a hollow pipe with a diameter larger than that of the hollow pipe of the barrel 3. The water stop wing ring 15 is welded at the middle position of the outer part of the pipe body 11 and arranged at the middle position of the bottom plate concrete 2. The water stop wing ring 15 is provided with a water-swelling water stop strip 18 above and below. The blocking plate comprises a second blocking plate 19 arranged inside the pipe body 11 and a first blocking plate 17 connected with the second blocking plate 19 through a first bolt 16. Two blocking plates are arranged inside the pipe body 11 and connected through bolts. The second blocking plate 19 is arranged inside the pipe body 11 and provided with the first bolt 16. The first blocking plate 17 is provided with a bolt hole corresponding to the first bolt 16. The first blocking plate 17 and the second blocking plate 19 are provided with a reserved hole through which the water pumping pipeline 6 and the measuring barrel 83 can pass. The base 14 is welded at the bottom end of the pipe body 11 and arranged below the foundation cushion layer of the well mouth. The base 14 is located between the bottom plate concrete 2 and the well mouth and can isolate the soil body and underground water.

[0033] The barrel 3 is arranged in the dewatering pipe well hole 4 and extends into the mouth sealing assembly 1 along the height direction of the dewatering pipe well hole 4. The barrel 3 is connected by multiple hollow pipes. The multiple hollow pipes are connected through threads 33. The length of the barrel 3 increases or decreases with the depth of the dewatering pipe well hole 4. The connection part of the multiple hollow pipes is provided with sealing glue or raw material 35. The barrel 3 is connected into a whole by the threads of the two ends of the multiple hollow pipes. After being screwed, the barrel 3 is coated with sealing glue or wrapped with raw material, so that the barrel 3 is sealed well and the underground water is prevented from leaking into the inside of the barrel 3 from the upper part of the barrel 3. The length of the hollow pipe of the lowermost section of the barrel 3 is about 3 meters. The lower end part is sealed by welding a porous plate 36. The water filtering holes 32 are arranged within a range of 2 meters from the sealed end. The outside of the hollow pipe of the lowermost section is wrapped with thin rock wool net and filter screen 31 for further filtration to prevent mud or other impurities from entering the inside of the barrel 3. The hollow pipe of the uppermost section of the barrel 3 extends into the mouth sealing assembly 1 by 100-200 mm and is provided with two symmetrical lifting rings 34 at the top end for the force point of the barrel 3 when the barrel 3 is removed after the use of the dewatering pipe well. The porous plate 36 is used for fixing the fixing cylinder 81 of the water level detector 8.

[0034] The water level detector 8 is located in the cylinder 3, and includes a fixed cylinder 81 and multiple measuring cylinders 83 that float up and down in the fixed cylinder 81 according to the water level changes in the well hole 4 of the dewatering pipe. The fixed cylinder 81 is a hollow tube with a sealed bottom and a first water inlet 82 at the bottom. Two symmetrical fixed bases 87 are welded to the outer side of the sealed end of the bottom of the fixed cylinder 81, and the fixed bases 87 are connected to the perforated plate 36 by a second bolt 86. The top of the fixed cylinder 81 is provided with a first limiting block 88 corresponding to the sliding groove 89 of the measuring cylinder 83. The multiple measuring cylinders 83 are multi-section telescopic and are made of PVC pipes or other hard plastic pipes of different colors for more accurate identification of water level changes. The top of the measuring cylinder 83 is provided with two symmetrical second limiting blocks 881, which are staggered from the sliding grooves 89 on both sides of the measuring cylinder 83. The bottom of the measuring cylinder 83 is sealed and equipped with a float 85 and a second water inlet. Two symmetrical grooves 89 and a measuring mark 84 are provided on its outer surface. The second water inlet is located at the connection end between the measuring cylinder 83 and the float 85. Groundwater can enter the interior of the water level monitor 8 through the water inlet, causing the float 85 to rise under buoyancy, which in turn causes the measuring cylinder 83 to rise. The measuring mark 84 is used to read water level changes.

[0035] The sealing plate of the mouth sealing assembly 1 is provided with a reserved opening for the measuring cylinder 83 to extend out. When the measuring cylinder 83 floats up, it passes through the opening, and the water level reading can be obtained because the measuring cylinder 83 is provided with a measuring mark 84. The readings before and after reflect the water level change.

[0036] Below, refer to Figs. 1-4 Based on the above structural description, the method of using the reusable well device with built-in water level monitoring of this utility model is described as follows:

[0037] Step 1: Assemble the measuring cylinder 83. The second water inlet holes of the upper and lower sections of the measuring cylinder 83 are symmetrical and not on the same vertical plane. Install the assembled measuring cylinder 83 in the fixed cylinder 81. Groundwater enters through the water inlet hole. When the water level reaches a certain height, the float 85 will generate upward buoyancy. The measuring cylinder 83 can then float up and down through the slide 89. The limiting block 88 is used to limit the maximum extension height of the measuring cylinder 83.

[0038] Step 2: Install the assembled water level detector 8 onto the perforated plate 36 using the second bolt 86, and weld the perforated plate 36 onto the hollow tube of the lowest section of the cylinder 3, so that the water level detector 8 is located inside the hollow tube. Then, wrap the lowest section of the hollow tube with thin rock wool netting and filter screen 31. Determine the total length of the cylinder 3 according to the depth of the dewatering pipe well hole 4. The hollow tubes of the cylinder 3 are connected by threads 33, and the connection is provided with sealant or raw material 35.

[0040] Fourth step: when the dewatering pipe well needs to be removed, the second blocking plate 19 is first removed, then the rope is used to pass through the lifting ring 34 to pull out the cylinder body 3 from the dewatering pipe well hole 4, after the cylinder body 3 is pulled out, the underwater concrete 13 with a grade higher than that of the engineering pile concrete is poured into the dewatering pipe well hole 4, the pouring surface is flat with the first blocking plate 17, and the poured concrete is chiseled, after the chiseling, the micro-expansion and anti-permeability concrete 12 with a grade higher than that of the foundation bottom plate concrete is continuously poured into the pipe body 11 to carry out the final sealing treatment, and the pouring surface is flat with the surface of the bottom plate concrete 2 of the foundation structure.

[0041] The above merely describes the specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can understand the transformation or replacement within the technical range disclosed by the present application, and all should be covered in the inclusive scope of the present application.
