Description

Technical Field

[0001] This utility model relates to the field of sewage treatment, and in particular to a prefabricated observation well. Background Technology

[0002] With increasing environmental awareness and technological advancements, many regions are promoting wastewater renovation projects. Wastewater renovation typically refers to upgrading and improving existing wastewater treatment systems or facilities to enhance their treatment efficiency, expand treatment capacity, and reduce their environmental impact.

[0028] like Figure 1 As shown, a prefabricated observation well includes a base 1 and multiple sections of well casing 2.

[0029] like Figure 1 , Figure 2 As shown, the base 1 is horizontally placed on the ground. Corner lugs 3 are provided around the base 1. Anchor rods 31 are vertically inserted through the corner lugs 3. The anchor rods 31 are used to extend into the ground.

[0030] like Figure 1 , Figure 2 As shown, multiple sections of well pipe 2 are vertically stacked on the base 1. A climbing frame 21 is installed inside the well pipe 2 for construction personnel to climb. The side wall of the lowest section of well pipe 2 is provided with a water inlet 22, and the lower end face is provided with an installation ring 23. The base 1 is provided with an installation groove 11 for the installation ring 23 to be inserted.

[0031] like Figure 1 , Figure 2 As shown, a retaining ring 24 is provided on the lower end face of the mounting ring 23, and a retaining groove 12 is provided on the bottom wall of the mounting groove 11 for the retaining ring 24 to be inserted, so as to increase the sealing between the base 1 and the lowest section of the well pipe 2 and avoid water leakage during use.

[0032] like Figure 1 , Figure 2 As shown, a screw 13 is horizontally provided on the side wall of the base 1, which passes through the mounting groove 11. A threaded tube 25 for threaded connection of the screw 13 is prefabricated on the side wall of the mounting ring 23, so as to fix the well pipe 2 when it is installed on the base 1, thereby increasing the stability of the connection position.

[0033] like Figure 1 , Figure 3 , Figure 4 As shown, the side wall of the mounting ring 23 is provided with a positioning block 26, and the base 1 is provided with a positioning groove 14 for the positioning block 26 to be embedded, so as to realize the rapid positioning of the bottom section of the well pipe 2, improve the installation speed, and ensure the construction progress.

[0034] like Figure 1, Figure 3 , Figure 4 As shown, the lower end of the well pipe 2 is provided with multiple dovetail blocks 27, and the upper end of the well pipe 2 is provided with a groove 15 for the dovetail blocks 27 to be inserted into and a dovetail groove 16 connecting the groove 15 and allowing the dovetail blocks 27 to slide into it. A vertical insertion hole 28 is provided on the well pipe 2, penetrating the dovetail blocks 27 and the dovetail groove 16, and a rod 29 is vertically inserted into the insertion hole 28.

[0035] like Figure 3 , Figure 4 As shown, the lower end of the well pipe 2 is provided with sealing rings 4 distributed on both sides of the dovetail block 27, and the upper end of the well pipe 2 is provided with sealing grooves 5 for the sealing rings 4 to be embedded in, so as to increase the sealing between the well pipes 2 and prevent water leakage during use.

[0036] like Figure 1 , Figure 5 As shown, a fixing ring 6 is provided on the inner wall of the uppermost section of the well pipe 2. A ruler 61 is vertically slidably connected inside the fixing ring 6, and a float plate 62 is provided at the lower end of the ruler 61.

[0037] When it is necessary to construct the observation well, first press the anchor rod 31 vertically into the ground, then hoist the base 1 to the ground and make the anchor rod 31 pass through the base 1. Then tighten the nut on the anchor rod 31 to achieve quick installation and fixation of the base 1.

[0038] Then, the bottom section of the well pipe 2 is hoisted above the base 1, aligning the positioning block 26 at the lower end of the well pipe 2 with the positioning groove 14, while simultaneously embedding the mounting ring 23 into the groove 15. Next, the screw 13 is inserted into the side wall of the base 1, and then the bolt is tightened so that the bolt is screwed into the threaded tube 25, thus achieving the installation and fixation of the bottom section of the well pipe 2.

[0039] Then, the other well pipes 2 are hoisted, so that the dovetail block 27 at the lower end of the well pipe 2 is embedded into the groove 15. Then, the well pipe 2 is rotated so that the dovetail block 27 slides into the dovetail groove 16, achieving axial locking and limiting. Then, the insertion rod 29 is vertically inserted into the insertion hole 28 in all the well pipes 2 to achieve circumferential fixing, thereby completing the installation and fixing of all the well pipes 2.

[0040] Then, the measuring rod 61 is vertically passed through the fixing rings 6 on all the well pipes 2. The float 62 is then installed at the lower end of the measuring rod 61. Finally, the old drainage pipe is connected to the inlet 22 on the lowest section of the well pipe 2, so that the sewage in the old drainage pipe is discharged into the observation well per unit time. Under the buoyancy of the float 62, the measuring rod 61 slides upward. Then, the scale on the measuring rod 61 is observed to measure the water depth and calculate the sewage discharge per unit time.

[0041] Therefore, by setting up prefabricated observation wells and adopting a modular well pipe structure, the observation wells can be quickly assembled and used on site, improving the construction progress of the observation wells and thus ensuring the progress of sewage treatment.
