[0002] With urban development and limited urban land, the trend of buildings and structures extending deeper and higher is inevitable. This expansion into underground spaces inevitably involves the impact of groundwater. In silty sand layers, well dewatering is commonly used. Before excavation, it is essential to ensure that the groundwater level is within 0.5-1 meter of the excavation surface. During basement foundation construction, the groundwater level must be at least 0.5 meters below the bottom of the foundation.

[0003] When constructing dewatering wells, drilling is required in the ground. Steel casings are used during drilling to prevent the borehole walls from collapsing, especially in soft soil or areas with high groundwater levels. The steel casings provide support, preventing collapse and maintaining the shape of the borehole. However, existing steel casings are prone to denting at both ends due to surrounding water pressure and soil conditions. Even when not in use, external factors can cause dents at both ends, affecting the casing's usability for future applications. Therefore, a new type of steel casing for sealing dewatering wells is proposed to address these issues. Utility Model Content

A second support plate 203 is movably connected to one side of each first support plate 202, the surface of which also contacts the inner wall of the steel casing body 1. Two first connecting ropes 204 are fixedly connected to the bottom of both the top of the first support plate 202 and the bottom of the second support plate 203, respectively. The two ends of the first connecting ropes 204 are fixedly connected to the top of the first support plate 202 and the second support plate 203. A first fixing plate 7 and a second fixing plate 4 are fixedly connected to the inner walls of the first support plate 202 and the second support plate 203, respectively. The first fixing plate 7 is in contact with one side of the second fixing plate 4, and a second connecting rope 201 is fixedly connected to one side of the first fixing plate 7. One end of the second connecting rope 201 is fixedly connected to one side of the second fixing plate 4. By setting the support mechanism 2, the surface and interior of both ends of the steel casing body 1 can be supported under the action of the support mechanism 2, so as to avoid deformation of both ends of the steel casing body 1 under pressure. Since the support force of both ends of the steel casing body 1 is poor, it is easy to dent when pressure is generated, thereby avoiding affecting the next use of the steel casing body 1. The purpose of supporting both ends of the steel casing body 1 and preventing dents from appearing under pressure is achieved.

[0018] Reference Figure 1 , Figure 2 and Figure 4 The inner wall and surface of the steel casing body 1 are respectively fixedly connected to the first guide rail 9 and the second guide rail 6. The inner wall and surface of the two first support plates 202 and the two second support plates 203 are respectively fixedly connected to the first guide block 3 and the second guide block 8. The surfaces of the first guide block 3 and the second guide block 8 are respectively slidably connected to the inner wall of the first guide rail 9 and the second guide rail 6. By setting the first guide rail 9, the second guide rail 6, the first guide block 3 and the second guide block 8 to work together, the stability of the first support plate 202 and the second support plate 203 during movement can be increased, and the jamming of the first support plate 202 and the second support plate 203 during movement can be avoided, thus achieving the purpose of increasing the stability of the first support plate 202 and the second support plate 203 during movement.
