The fixed pile part includes a base, on which a column is arranged. A sliding plate is slidably connected to the column. Positioning rods are evenly arranged on the sliding plate and are fixedly connected to the sliding plate. A through hole for the positioning rod to pass through is opened on the upper surface of the base. A hammering block is slidably connected to the column, and the hammering block is located above the sliding plate. Several connecting parts are arranged on the column and above the hammering block. The connecting part includes a snap ring, on which an extension part is arranged. Threaded holes are evenly arranged on the outer surface of the column. A bolt is threadedly connected to the extension part. Two ring plates are rotatably connected to the outer surface of the snap ring. A sleeve is arranged on the outer surface of the ring plate. The horizontal heights of the two sleeves in the same connecting part are equal. A rotating cylinder is threadedly connected to the inside of the sleeve.

Detailed Embodiments

[0017] The following further describes the specific embodiments of the present invention with reference to the drawings.

[0018] As Figures 1-5As shown in the figure, a foundation pit retaining device made of steel structure includes several fixed pile parts and several steel pipes 1 of different lengths for connecting two fixed pile parts. The fixed pile part includes a base 2, on which a column 3 is arranged. A sliding plate 4 is slidably connected to the column 3. Positioning rods 5 are evenly arranged on the sliding plate 4 and fixedly connected to the sliding plate 4. Through holes 6 for the positioning rods 5 to pass through are opened on the upper surface of the base 2. A hammering block 7 is slidably connected to the column 3, and the hammering block 7 is located above the sliding plate 4. Several connecting parts are arranged on the column 3 and above the hammering block 7. The connecting part includes a snap ring 8, on which an extension part 9 is arranged. Threaded holes 10 are evenly arranged on the outer surface of the column 3. A bolt 11 is threadedly connected to the extension part 9. Two ring plates 12 are rotatably connected to the outer surface of the snap ring 8. A sleeve 13 is arranged on the outer surface of the ring plate 12. The horizontal heights of the two sleeves 13 in the same connecting part are equal. A rotating cylinder 14 is threadedly connected inside the sleeve 13.

[0019] When installing the retaining device around the foundation pit, first measure the distance on the ground and mark the points. After the marking is completed, place the fixed pile parts one by one at the marked points, and then fix the base 2 to the ground. Specifically, when fixing the base 2, insert the lower end of the positioning rod 5 into the through hole 6 on the base 2, and then fix the lowermost connecting part to the highest fixable position on the column 3 to reserve space for the movement of the hammering block 7. When fixing the base 2, lift the hammering block 7 along the column 3 and then release the hammering block 7. The hammering block 7 hits the positioning rod 5 by its own gravity and prompts the positioning rod 5 to be inserted into the soil layer. The sliding plate 4 cooperates with the through hole 6 to enable the positioning rod 5 to move vertically downward. When moving the hammering block 7 to a higher position on the column 3, a downward pulling force can also be artificially applied to the hammering block 7 to increase the falling speed of the hammering block 7, so that the hammering block 7 can hammer the positioning rod 5 into the soil layer faster. After the hammering of the positioning rod 5 is completed, the hammering block 7 also moves along the column and to the lower part of the column. Then, evenly disperse and fix multiple connecting parts on the column 3 in sequence. Then insert one end of the steel pipe 1 into the rotating cylinder 14, and the other end of the steel pipe 1 does not enter the rotating cylinder 14 at the same height in the adjacent fixed pile part. At this time, by rotating the rotating cylinder 14, the rotating cylinder 14 can be screwed out of the sleeve 13, so that the other end of the steel pipe 1 can enter the rotating cylinder 14. After all the steel pipes 1 are installed, the installation of the retaining device is completed.

[0020] The retaining device can be fully enclosed on all sides or leave an entrance and exit.

[0021] Further, a baffle 15 is provided at the upper end of the column 3. When the extension part 9 in the connection part at the uppermost position of the column 3 abuts against the lower surface of the baffle 15, the bolt 11 on the extension part 9 can be connected to the threaded hole 10 at the highest position on the outer surface of the column 3, which is convenient for quickly positioning and connecting the connection part at the uppermost position to the column 3. And when the remaining connection parts abut against the connection part above them in sequence, the connection parts can all be connected to the threaded hole 10 on the outer surface of the column 3 through the bolt 11, which is convenient for quickly positioning and connecting the remaining connection parts to the column 3.

[0022] Further, an annular handrail 16 is provided on the outer surface of the hammer block 7, and the handrail 16 is fixedly connected to the hammer block 7, which is convenient for controlling the movement of the hammer block 7 through the handrail 16.

[0023] Further, a blind hole 17 for accommodating the lower end of the positioning rod 5 is provided on the upper surface of the base 2. When carrying the device, the lower end of the positioning rod 5 can be placed in the blind hole 17 to prevent the positioning rod 5 from protruding from the through hole 6, so as to improve the portability of the device.

[0024] Further, a spike part is provided at the lower end of the positioning rod 5, which is convenient for the positioning rod 5 to be inserted into the soil layer faster.

[0025] This kind of retaining device can integrate all parts except the steel pipe 1 onto the fixed pile part, thus avoiding the loss of parts. Whether in use or during demolition, there is no need to disassemble the fixed pile part, which can save a lot of time, is easy to use, and the ring plate 12 can rotate freely along the snap ring 8. Therefore, the fixed pile part can be arranged along the periphery of the foundation pit, making the retaining device more conform to the foundation pit, so as to reduce the retaining of unnecessary areas and has a good use effect.

[0026] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
