Technical Field
[0001] This utility model relates to the field of construction technology for dewatering well projects, specifically a steel round pipe sleeve pile tip for dewatering well construction. Background Technology
[0002] The project is located in the pre-depositional sedimentary zone of the modern Yangtze River underwater delta. The surrounding area is dotted with islands and crisscrossed by waterways. Affected by the tidal currents between the islands, the underwater landform is complex and diverse. The geological conditions, from top to bottom, are: silt, silty clay, completely weathered tuff, strongly weathered tuff, and moderately weathered tuff. The construction area of the dewatering well project is about 3km long. The prerequisite for construction is that the sand filling inside the steel cylinder has been completed and the open water inside the cylinder has been pumped out. Construction starts from the two sections of the steel cylinder weir, which includes 124 steel cylinder dewatering wells and 123 auxiliary dewatering wells. The main construction process is as follows: (1) pumping out the open water inside the steel cylinder, (2) drilling the dewatering wells, (3) lowering the well pipes, (4) sealing the well pipe openings, (5) backfilling with gravel, (6) installing submersible pumps, and (7) pumping operations.
[0003] Existing methods for installing dewatering wells involve directly driving a vibrating steel pipe sleeve into a steel cylinder using a pump. However, this method suffers from low efficiency due to the significant frictional resistance generated by the consolidation of backfill sand upon contact with water, and frequent damage to the pump. A new method, tailored to the specific site conditions and efficiency considerations, involves welding a quadrangular pile tip to the steel pipe on-site. This breaks up the consolidated sand, reducing the frictional resistance of the steel pipe during installation. A steel pipe collar is designed on the pile tip; installing the steel pipe within this collar before installation effectively reduces deviation during the installation process.
[0004] However, this method has certain drawbacks: on-site welding and installation may require more time and space, which may limit the flexibility of construction activities, and the welding process may generate smoke and noise pollution, which may have a potential impact on the on-site environment and workers' health. Therefore, a steel round pipe sleeve pile tip for dewatering well construction is proposed to solve the problems mentioned above. Utility Model Content

[0007] The second steel tube sleeve is equipped with a positioning mechanism connected to the steel tube sleeve. The positioning mechanism includes a rotating disk rotatably disposed inside the second steel tube sleeve, a locking block slidably disposed inside the second steel tube sleeve and extending to its outside, a pulley rotatably installed at one end of the locking block and rollingly engaged with the rotating disk, a sleeve installed on the upper surface of the rotating disk, a driven gear fixedly installed on the outer surface of the top end of the sleeve, a drive motor fixedly installed on the inner bottom wall of the second steel tube sleeve, and a transmission gear fixedly installed on the output shaft of the drive motor and meshing with the driven gear.

A limit slider is fixedly installed on the inner side of the through hole, and a limit groove is opened on the side wall of the locking block to slide and connect with the limit slider.
[0011] Furthermore, the interior of the rotating disk is provided with a groove adapted to the pulley, and the pulley is in rolling connection with the inner wall of the groove.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1:
[0025] Please see Figure 1 and Figure 2 A steel round pipe sleeve pile tip for dewatering well construction includes a steel round pipe sleeve pile tip body 1 for dry dewatering well construction. The steel round pipe sleeve pile tip body 1 includes a steel round pipe sleeve one 101, a steel round pipe sleeve two 102 and a pile tip 103 distributed from top to bottom. The steel round pipe sleeve two 102 is welded and installed at the bottom end of the steel round pipe sleeve one 101, and the bottom end of the steel round pipe sleeve two 102 extends into the interior of the pile tip 103.
[0026] It should be noted that the pile tip 103 is shaped like a quadrangular prism. By connecting the quadrangular pile tip 103 to the steel round tube sleeve pile, the consolidated sand body is broken up, reducing the frictional resistance of the steel round tube during driving. A steel round tube collar is designed on the pile tip. Installing the steel round tube in the fixed collar before driving can effectively reduce the deviation during the driving process. This achieves the purpose of improving work efficiency and reducing wear and tear on the driving and pulling machines.
[0027] Example 2:
[0028] Please see Figures 2 to 5 Based on Embodiment 1, a positioning mechanism 2 connected to the steel tube sleeve 103 is provided inside the steel tube sleeve 2 102. The positioning mechanism 2 includes a rotating disk 201 rotatably disposed inside the steel tube sleeve 2 102, a locking block 202 slidably disposed inside the steel tube sleeve 2 102 and extending outward therefrom, a pulley 203 rotatably mounted on one end of the locking block 202 and rollingly engaged with the rotating disk 201, a sleeve 205 mounted on the upper surface of the rotating disk 201, a driven gear 206 fixedly mounted on the outer surface of the top end of the sleeve 205, a drive motor 207 fixedly mounted on the inner bottom wall of the steel tube sleeve 2 102, and a transmission gear 208 fixedly mounted on the output shaft of the drive motor 207 and meshing with the driven gear 206. The pile tip 103 has an installation groove 1031 inside, and the inner side wall of the installation groove 1031 has a positioning groove 1032 adapted to the locking block 202. After extending out of the steel round sleeve 102, the locking block 202 can be precisely inserted into the positioning groove 1032, ensuring a stable connection between the pile tip body and the sleeve, which helps to ensure the stability and reliability of the entire structure.
[0029] Specifically, the steel round tube sleeve 202 is hollow inside, and a through hole for the telescopic hole of the locking block 202 is opened inside the steel round tube sleeve 202. A limit slider 210 is fixedly installed on the inner side of the through hole, and a limit groove 209 is opened on the side wall of the locking block 202 to slide and connect with the limit slider 210. The rotating disk 201 has a sliding groove 204 adapted to the pulley 203 inside, and the pulley 203 is in rolling connection with the inner wall of the sliding groove 204. When the drive motor 207 is started, it drives the transmission gear 208. The transmission gear 208 rotates and meshes with the driven gear 206 to drive the rotating disk 201. The rotation of the rotating disk 201 drives the locking block 202 to move through the sliding engagement of the sliding groove 204 and the pulley 203, so that it extends out of the steel round tube sleeve 202 and inserts into the positioning groove 1032, thereby realizing the installation of the steel round tube sleeve pile tip body 1.
[0030] In this embodiment, there are three of each of the sliding groove 204, the locking block 202, and the pulley 203, and the three locking blocks 202 are arranged in a triangular shape at equal intervals on the outside of the rotating disk 201. The sleeve 205 is hollow inside and is fixedly installed on the upper surface of the rotating disk 201. The bearing of the rotating disk 201 is installed inside the steel round tube sleeve 102.
[0031] The working principle of the above embodiments is as follows:
[0032] In use, first insert the bottom end of the steel round tube sleeve 102 into the installation groove 1031, then start the drive motor 207 to drive the transmission gear 208. The transmission gear 208 rotates and meshes with the driven gear 206 to drive the rotating disk 201. The rotating disk 201 rotates and drives the locking block 202 to move through the sliding engagement of the sliding groove 204 and the sliding wheel 203, so that it extends out of the steel round tube sleeve 102 and is inserted into the positioning groove 1032, thereby realizing the installation of the steel round tube sleeve pile tip body 1.
[0033] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.
[0034] Any connection method that can achieve its beneficial effect can be implemented. In addition, all electrical components in this embodiment are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing public power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
