Abstract
Description
Technical Field
[0001] The utility model relates to a wellbore lowering device, in particular to a pipe well dewatering socket-and-spigot type wellbore sinking auxiliary device, belonging to the technical field of pipe well construction. Background Art
[0002] During construction, when the groundwater level is shallow, pipe well dewatering technology will be used around the foundation pit. Generally, the depth of the pipe well during dewatering is not less than 15m. When lowering the pipe well, 4 to 5 people are required to use wire ropes to help fasten the bottom of the well before the well can be sunk into the well section by section. Since this operation is performed at the wellhead, there is a risk of the well falling into the well during the sinking process. In addition, this construction method is time-consuming, labor-intensive, and inefficient. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a pipe well dewatering socket-type wellbore sinking auxiliary device, which avoids the risk of the wellbore falling during the sinking process and is easy to use and simple to operate.
[0004] The technical solution adopted by the utility model to solve the technical problem is:
[0005] A socket-and-spigot type pipe well sinking auxiliary device for water reduction comprises a steel pipe and a round steel lifting ring. A round steel lifting ring is provided on the top of the steel pipe. The outside of the steel pipe is connected to a steel cage through transverse reinforcement, and the bottom of the steel cage is distributed in a cone shape. Three hook connecting reinforcements are evenly arranged on the outside of the steel cage, and a hook claw is provided at the bottom of the hook connecting reinforcement.
[0006] The steel cage is composed of three outer ring steel bars, which are evenly distributed outside the steel pipe, and a transverse reinforcement is connected between each outer ring steel bar and the steel pipe.
[0007] The top of the steel pipe extends out of the steel cage, and the round steel lifting ring is located on the steel pipe above the steel cage.
[0008] The hook connecting bar is located on one side of the outer ring steel bar, and the upper part of the hook connecting bar is welded to the upper part of the outer ring steel bar, and the hook claw at the bottom of the hook connecting bar is located outside the steel cage.
[0009] The hooks of the claws face toward the interior of the steel cage.
[0010] The outer diameter of the steel cage matches the inner diameter of the wellbore.
[0011] The positive beneficial effects of the utility model are:
[0012] 1. The utility model sets hook connecting ribs on the outside of the steel cage and sets hook claws at the bottom of the hook connecting ribs, which plays a role in limiting the wellbore and effectively prevents the wellbore from falling into the pipe well during the sinking process.
[0013] 2. The utility model provides a steel cage on the outside of the steel pipe. Before construction, the pre-sunk shaft is clamped on the steel cage above the steel claw and lifted up from the suspended ground. When the tapered end of the steel cage extends into the interior of the sunken shaft, the hook claw is squeezed and contracted toward the interior of the steel cage, and the lifted shaft moves toward the shaft below, thereby completing the docking between the upper and lower shafts, ensuring the accuracy of the docking between the shafts, greatly improving construction efficiency, and being easy to use and simple to operate.

[0019] The present invention will be further explained and illustrated below with reference to the accompanying drawings:
[0020] For example, see Figures 1-4 A pipe well dewatering socket-type wellbore sinking auxiliary device includes a steel pipe 1 and a round steel lifting ring 2. A round steel lifting ring 2 is provided on the top of the steel pipe 1. A steel cage 3 is connected to the outside of the steel pipe 1 through a transverse reinforcement 4, and the bottom of the steel cage 3 is distributed in a cone shape. Three hook connecting reinforcements 5 are evenly arranged around the steel cage 3, and a hook claw 6 is provided at the bottom of the hook connecting reinforcement 5.
[0021] The steel cage 3 is composed of three outer ring steel bars 301 , which are evenly distributed outside the steel pipe 1 , and a transverse reinforcement 4 is connected between each outer ring steel bar 301 and the steel pipe 1 .
[0022] The top of the steel pipe 1 extends out of the steel cage 3 , and the round steel lifting ring 2 is located on the steel pipe 1 above the steel cage 3 .
[0023] The hook connecting rib 5 is located on one side of the outer ring steel bar 301 , the upper portion of the hook connecting rib 5 is welded to the upper portion of the outer ring steel bar 301 , and the hook claw 6 at the bottom of the hook connecting rib 5 is located outside the steel cage 3 .
[0024] The hooks of the claws 6 face the interior of the reinforcement cage 3 .
[0025] The outer diameter of the steel cage 3 matches the inner diameter of the wellbore.
[0026] In the above description, each outer ring steel bar outside the steel cage is connected to a hook connecting bar, the top of the hook connecting bar is welded to the outer ring steel bar outside the steel cage, and the steel claw is located outside the steel cage to ensure that the steel sheet can move toward the inside of the steel cage when squeezed by external force.
[0027] In the above description, the steel claw is a hook-shaped steel piece.
[0028] In the above description, the bottom of the steel pipe is welded to the center of the bottom of the steel cage, and the top of the steel pipe protrudes from the steel cage.
[0029] In the above description, the outer diameter of the steel cage matches the inner diameter of the wellbore.
[0030] In the above description, the steel claw is located at the lower end of the straight cylindrical portion of the steel cage, at the non-tapered portion.
[0031] Working principle:
[0032] When the first section of the concrete shaft is sunk into place, the device is used to hoist in the second section of the shaft. After the device reaches the predetermined position, it continues to sink, and the retractable hook retracts to sink the shaft. This process repeats until the shaft is completely constructed, and the device can be pulled out.
[0033] The utility model provides a hook claw at the bottom of the hook connecting reinforcement, which plays a role in limiting the wellbore and effectively prevents the wellbore from falling into the pipe well during the sinking process. At the same time, by squeezing the steel claw into the interior of the steel cage, the wellbore can be moved down along the steel cage, thereby completing the docking between the upper and lower wellbores, ensuring the accuracy of the docking between the wellbores, greatly improving construction efficiency, and being easy to use and simple to operate.
