Description

Technical Field

[0001] This utility model belongs to the technical field of support devices, specifically a combined steel sheet pile foundation pit support device. Background Technology

[0002] In the construction of building foundation pits, steel sheet pile support systems are widely used due to their advantages such as convenient construction and reusability. Conventional support structures form a vertical retaining structure by driving steel sheet piles into the ground along the inner wall of the foundation pit, and then connecting the steel sheet piles on both sides through horizontal support components to resist the lateral pressure of the soil and control the deformation of the foundation pit.

[0003] In existing technologies, lateral support components typically use steel pipes or H-beams of fixed length, requiring pre-customization or selection of suitable specifications based on the pit width. However, the pit widths vary significantly across different projects, and the pit dimensions within the same site may also change due to design adjustments. When the length of the lateral support component does not match the pit width, traditional solutions require replacing it with lateral support components of different lengths, resulting in high adaptation costs, the need to stock multiple specifications of lateral support components, increased material procurement, and reduced applicability of the lateral support components. To address these issues, we propose a combined steel sheet pile pit support device. Utility Model Content

Detailed Implementation

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Example 1

[0028] Please see Figure 1 , Figure 2 , Figure 3 and Figure 7 This utility model provides a technical solution: a combined sheet pile foundation pit support device, comprising multiple sets of sheet pile bodies 100 and transverse support components. This device provides transverse support for the sheet pile bodies 100 and allows for adjustment of the length of the transverse support components when transferring them to the next foundation pit, increasing the applicability of the transverse support components to foundation pits of different widths. The multiple sets of sheet piles are arranged in a straight line on both sides of the transverse support components. The transverse support components include:

[0029] A horizontal plate 101, a left block 200, and a right block 205 are set on the surface of the steel sheet pile body 100. An inner column 202 is fixedly set on the left block 200, and a spiral plate 204 is fixedly set on the surface of the right block 205. The end of the inner column 202 passes through the interior of the spiral plate 204.

[0030] The front and back of the U-shaped plate 204 are provided with two sets of adjustment grooves 206. The inner column 202 is provided with two sets of T-shaped screws 208, and the working end of the T-shaped screw 208 passes through the interior of the adjustment groove 206. The inner column 202 is provided with an opening for the working end of the T-shaped screw 208 to pass through.

[0031] The T-screw 208 is connected to the outside by a threaded ring 210. A rubber plug 207 is fitted on the outside of the T-screw 208. The rubber plug 207 prevents external impurities from adhering to the working end of the T-screw 208 during use, thereby avoiding the wear of impurities on the inner wall and outer wall of the T-screw 208 when the threaded ring 210 is loosened at the end of the T-screw 208.

[0032] Two sets of vertical plates are fixedly installed on both the right block 205 and the left block 200. The left block 200 is fixedly combined with the left horizontal plate 101 and the right block 205 is fixedly combined with the right horizontal plate 101 through the vertical plates and fixing bolts. The vertical plates and the horizontal plates 101 are fixedly connected by fixing bolts. When the horizontal support is transferred to the next foundation pit for use, before adjusting the length of the horizontal support, the two sets of vertical plates and the horizontal plate 101 on the left block 200 and the right block 205 are in a de-fixed state and the fixing bolts have been removed.

[0033] Example 2

[0034] Please refer to Example 1. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 A movable component is provided between the inner column 202 and the U-shaped plate 204. The movable component includes a fixed plate 201 fixed to the top of the inner column 202 and a mounting plate 203 fixed to the top of the U-shaped plate 204. A lead screw 212 is rotatably provided inside the fixed plate 201, and one end of the lead screw 212 passes through the interior of the mounting plate 203.

[0035] A nut seat 214 is provided on the outside of the lead screw 212. The movable plate 213 and the mounting plate 203 can slide on the outside of the lead screw 212 and the T-shaped rod 211. At the same time, the mounting plate 203 also slides on the lead screw 212. The movable plate 213 is fixedly provided on the outside of the nut seat 214. Two sets of T-shaped rods 211 are fixedly provided on the side of the fixed plate 201. The mounting plate 203 can slide on the T-shaped rods 211. A handle 209 is fixedly provided on the other end of the lead screw 212.

[0036] In summary, when transferring the equipment from one foundation pit to another, the length of the transverse support assembly can be adjusted. To adjust the length, the rubber plug 207 is moved outward from the working end of the T-shaped screw 208 and pulled off. Then, the threaded ring 210 is loosened by rotating it away from the U-shaped plate 204. Next, the handle 209 is held and rotated to the left or right, causing the lead screw 212 to rotate. The nut seat 214 located outside the lead screw 212 then moves to the left or right, causing the moving plate 21 to move. 3. Move the moving plate 213 to move the lower U-shaped plate 204 towards or away from the left block 200. The U-shaped plate 204 moves the right block 205 (moving to the left reduces the length of the horizontal support component, and vice versa). At this time, the T-shaped screw 208 slides in the adjustment groove 206. Then, when it moves to the appropriate position, stop rotating the handle 209. At this time, adjust the length of the horizontal support component. Finally, rotate the threaded ring 210 towards the U-shaped plate 204 to tighten it, which can fix the inner column 202 and the U-shaped plate 204.

[0037] Example 3

[0038] Please refer to Example 2. Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 The movable plate 213 is equipped with a cleaning component, which includes two sets of brush holders 303 on both sides of the movable plate 213. The front and back of the brush holders 303 are equipped with connecting plates 304. When the bristles and brush holders 303 are severely worn after prolonged use, they need to be replaced. To replace them, unscrew the screws on the connecting plates 304. Then, remove the brush holders 303 located at the bottom of the lead screw 212, and then remove the small arc plate 305 and the large arc plate 306 located at the bottom of the lead screw 212. Then, unscrew the mounting bolts on the upper plate 300 to remove the brush holders 303, the small arc plate 305, and the large arc plate 306 on the lead screw 212 (and the cleaning component can be removed). Then, follow the reverse principle to replace the bristles and brush holders 303 (that is, install the new cleaning component). The connecting plates 304 are equipped with screws, and the working end of the screws extends into the interior of the brush holders 303.

[0039] An upper plate 300 is fixedly installed between the tops of the two brush holders 303, and the upper plate 300 is fixedly connected to the movable plate 213 by mounting bolts.

[0040] The T-shaped rod 211 is provided with multiple sets of small arc plates 305 and multiple sets of large arc plates 306 on its exterior. Each side of the small arc plate 305 and the large arc plate 306 is provided with multiple sets of oblique bristles. Two sets of mounting brackets 301 are fixedly provided on one side of the brush holder 303. The small arc plate 305 and the large arc plate 306 are fixed on the mounting brackets 301. The other side of the small arc plate 305 and the large arc plate 306 has no surface with multiple bristles that contacts the side of the moving plate 213.

[0041] In summary, when the nut seat 214 moves the moving plate 213, to prevent impurities from adhering to the outer walls of the lead screw 212 and T-shaped rod 211 during use and causing wear on the contact area with the inner wall of the mounting plate 203, the inner wall of the nut seat 214, and the outer walls of the lead screw 212 and T-shaped rod 211, the brush holder 303 and multiple sets of bristles clean the impurities adhering to the outer walls of the T-shaped rod 211 and lead screw 212. Cleaning is achieved by the movement of the nut seat 214. When the nut seat 214 moves the moving plate 213, it also moves the cleaning component. At this time, the multiple sets of bristles on the brush holder 303, small arc plate 305, and large arc plate 306 located on both sides of the moving plate 213 clean the impurities adhering to the outer walls of the T-shaped rod 211 and lead screw 212, reducing impurities and thus reducing the wear on the inner wall of the nut seat 214 and the lead screw 212. The probability of wear on the outer wall of the T-shaped rod 211 is reduced. Moreover, the multiple sets of inclined bristles on the small arc plate 305 and the large arc plate 306 can clean the areas not cleaned between the moving plate 213 and the brush holder 303. This avoids the situation where some impurities will still wear on the inner wall of the nut seat 214 and the outer wall of the lead rod 212 if the nut seat 212 is not cleaned when it starts to rotate and drives the nut seat 214 to move. When the nut seat 214 drives the moving plate 213 to move, it can drive the inclined bristles to move and sweep the impurities attached to the lead rod 212 and the T-shaped rod 211 to the outside for cleaning. When the nut seat 214 moves to a suitable position on one side, the handle 209 is reversed, which drives the lead rod 212 to reverse. Then the nut seat 214 moves to the other side. This process is repeated many times to clean the area.

[0042] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
