Description

Technical Field

[0001] This utility model relates to the field of sealing trench construction technology, specifically a sealing trench construction structure for vacuum preloading foundation treatment of rock-filled sites. Background Technology

[0002] In the construction of rock-filled sites, vacuum preloading is a common construction method to ensure the compaction of the foundation. This involves first laying a sand cushion layer on the surface of the soft soil foundation requiring reinforcement, then burying vertical drainage pipes, and finally covering it with an airtight membrane to isolate it from the atmosphere. The ends of the membrane are then buried and compressed. A vacuum pump or other vacuum method is used to create a negative pressure under the membrane through water-absorbing pipes buried within the sand cushion layer, increasing the effective stress of the foundation. The sealing trench is a crucial component of vacuum preloading. Its main function is to ensure the airtightness of the preloading site, block the connection between water and air inside and outside the preloading site, and stabilize the vacuum level. The airtightness of the sealing trench is a key measure to ensure the effectiveness of vacuum preloading. During construction, a large amount of crushed stone is needed to increase the stability of the sealing trench. The crushed stone is often broken into appropriately sized pieces by a hydraulic rock splitter. The hydraulic rock splitter takes advantage of the brittle nature of rock and concrete, utilizing the wedge principle to release a large splitting force outward from the narrowest opening, achieving stone crushing.

[0003] The existing hydraulic rock splitters used in quarries require workers to operate a drilling machine to drill holes in the stone before inserting the rock splitter into the holes. This makes rock splitting inconvenient and inefficient. Utility Model Content

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The hydraulic rock splitter used in this quarry lowers the third support plate through the first and second electromagnets. The third support plate then drives the screw rod to lower through the sleeve. The screw rod rotates through the motor, which then drills holes in the stone without the need for manual operation, making it easier to drill holes in the stone.

[0012] 2. The hydraulic rock splitter used in this quarry rotates the rotating block by means of a handle, which in turn causes the hydraulic rod and the auger rod to switch positions. Then, the first electromagnet and the second electromagnet cause the first support plate to descend, which in turn causes the first support plate to drive the hydraulic rod to descend. This causes the first expansion plate and the second expansion plate to fall into the holes opened by the auger rod on the surface of the stone. Then, the pump station causes the hydraulic rod to drive the expansion block to descend, which in turn causes the first expansion plate and the second expansion plate to expand, thereby cracking the stone and making the stone cracking more efficient.

[0020] The bottom end of the telescopic cylinder 13 is fixedly connected to the third support plate 20 on the other side of the rotating block 8. The middle part of the third support plate 20 is fixedly connected to the sleeve 22. One end of the spiral rod 10 is movably sleeved in the middle part of the third support plate 20. The output shaft of the motor 21 is fixedly connected to one end of the spiral rod 10 above the sleeve 22. One end of the third support plate 20 is fixedly connected to the third slider 19.

The screw rod 10 is then rotated by the motor 21, thus drilling holes in the stone without the need for manual operation, making it easier to drill holes in the stone. The rotating block 8 is then rotated by the handle 7, which causes the hydraulic rod 14 and the screw rod 10 to switch positions. The first support plate 15 is then lowered by the first electromagnet 16 and the second electromagnet 29, which in turn drives the hydraulic rod 14 to descend. This causes the first expansion plate 27 and the second expansion plate 28 to fall into the holes drilled by the screw rod 10 on the stone surface. The hydraulic rod 14 is then driven by the pump station 5 to descend the expansion block 26, which causes the first expansion plate 27 and the second expansion plate 28 to expand, thus cracking the stone and increasing the stone cracking efficiency.
