Description

Technical Field

[0001] The utility model relates to the technical field of precipitation well protection, and particularly relates to a precipitation wellhead protection device. Background Technique

[0002] Foundation pit dewatering means that when excavating a foundation pit, the groundwater level is higher than the excavation bottom surface, and groundwater will continuously seep into the pit. To ensure that the foundation pit can be constructed under dry conditions and prevent problems such as slope instability, foundation quicksand, bottom heave, bottom piping, and reduction of foundation bearing capacity, dewatering work is carried out. At present, foundation pit dewatering mostly adopts the form of dewatering wells. However, after the construction of the dewatering wells is completed, due to the complex environment, there are various safety hazards. Therefore, safety protection measures need to be taken to prevent workers from falling and ensure the personal safety of workers and the smooth progress of on-site dewatering work.

[0003] In the prior art, steel pipe fasteners are mostly used for protection. However, this method not only occupies a large space but also is not easy to install and disassemble, thus causing waste of space resources and human resources.

[0004] To solve the above problems, this application proposes a precipitation wellhead protection device that is convenient to use and does not occupy too much space. Content of the Utility Model

[0005] In order to overcome the problems that the existing protection method not only occupies a large space but also is not easy to install and disassemble, the utility model provides a precipitation wellhead protection device. The technical solution is as follows:

[0006] A precipitation wellhead protection device includes a support skeleton that can be hung on the edge of the precipitation wellhead and a protection barrel sleeved outside the support skeleton. A pipe penetration opening is provided on the upper end surface of the protection barrel; the support skeleton includes an inner skeleton located inside the precipitation wellhead and an outer skeleton located outside the precipitation wellhead and between the protection barrel. The inner skeleton includes an inner ring located inside the precipitation wellhead. A plurality of hanging rods are uniformly arranged on the inner ring. The upper ends of the hanging rods are bent outward to form hooks. The hooks can be hooked on the edge of the precipitation wellhead, and the outer ends of the hooks are connected with an outer ring sleeved on the precipitation wellhead through a connecting rod.

[0007] Further, a connecting block is horizontally arranged at the outer end of the hook, a connecting hook is horizontally arranged at the upper end of the connecting rod, and a groove for placing the connecting hook is provided on the connecting block. The outer skeleton and the inner skeleton are hung on the groove on the connecting block through the connecting hook, which is simple to operate and convenient for installation and disassembly.

[0008] Further, an observation opening is provided on the upper end surface of the protection barrel and is equipped with a cover.

[0009] Further, a protective net is arranged inside the inner ring. The protective net can not only prevent workers from falling into the well when they check the situation inside the well through the observation port, but also provide protection when the protective barrel of this protective device becomes loose due to corrosion or other reasons after long-term use.

[0010] Further, a conical rubber tube is fixed at the position of the pipe passing opening on the upper end face of the protective barrel, and the thin tube end of the conical rubber tube is the outer end. The conical rubber tube can tighten the pipeline inside the pipe passing opening, improve the protection at the pipe passing opening, and prevent garbage or foreign objects from entering the precipitation well through the pipe passing opening.

[0011] Further, a plurality of positioning screws are symmetrically arranged on the barrel body of the protective barrel. Reinforcing blocks are fixed on the barrel body of the protective barrel at the positions of the positioning screws. The positioning screws are threadedly connected with the reinforcing blocks, and one end of the positioning screw penetrates through the reinforcing block and the barrel body of the protective barrel and can abut against the outer wall of the precipitation well opening. The positioning screws can position and fix the protective barrel, prevent it from being continuously vibrated and causing increased frictional wear due to strong winds, construction, etc., and reduce the service life.

[0012] Further, an arc-shaped clamping plate is rotatably arranged at the inner end of the positioning screw, and a rubber pad is arranged on the inner side surface of the arc-shaped clamping plate.

[0013] Further, the protective barrel is made of iron sheet, and the support skeleton and the protective net are both made of steel bars.

[0014] Further, a reflective warning strip is arranged on the barrel body of the protective barrel.

[0015] Further, the outer diameter of the inner ring is slightly smaller than the inner diameter of the precipitation well opening, and the inner diameter of the outer ring is slightly larger than the outer diameter of the precipitation well opening, so that the support skeleton is more stable, and the problem that the support skeleton is prone to large-amplitude shaking due to the too large difference in the diameters of the inner ring, outer ring and the precipitation well opening and the unstable placement is avoided.

[0016] The beneficial effects of the technical solution provided by the present utility model are as follows: The device has a simple structure and is convenient to use. Through the support skeleton hung on the edge of the precipitation well opening and the protective barrel sleeved outside the support skeleton, it can not only quickly protect the precipitation well opening, but also occupy a small space and save space resources;

[0017] The protective barrel made of iron sheet of this device can block garbage and foreign objects at the construction site from entering the precipitation well and prevent the garbage and foreign objects from damaging the water pump; furthermore, the support skeleton provides support force for the iron sheet protective barrel to prevent the protective barrel from being severely deformed by external forces;

[0018] In addition, the device is also provided with an observation port for workers to observe the situation inside the precipitation well, and a steel wire protection net is arranged on the inner skeleton to further improve the protection effect. Because in the construction environment, the iron sheet protection barrel is prone to corrosion and the protection performance will gradually weaken, so the protection net becomes the second line of defense for safety protection, thus ensuring the continuous and effective protection effect of the device.
