Description

Technical Field

[0001] The invention relates to the technical field of pile foundation hole slurry treatment, in particular to a pile foundation hole slurry collection device. Background Art

[0002] Rotary drilling construction is a modern pile foundation construction technology, which is mainly used to form holes in soil or rock for subsequent pouring of concrete to make pile foundations. During the rotary drilling process, mud wall drilling technology is often used. The mud wall has the functions of stabilizing the hole wall, suspending drill cuttings, and controlling pressure.

[0003] During the construction process, a mud pool is prepared and mud is prepared at the construction site. During the process of drilling holes for mud wall pile foundations by rotary drilling, mud is injected at the same time. The mud and drill cuttings in the hole are mixed together. The mud is circulated in the hole through a mud pump to bring the drill cuttings out of the hole. After screening, sedimentation and other treatments, the mud is re-injected into the hole to complete the cycle.

[0004] However, when the pile foundation drilling slag is lifted from the hole, the mud is lifted with it. When the drilling slag is lifted to the hole mouth, the internal mud is scattered around the casing. At the same time, the drilling slag and mud attached to the rotary drill will be scattered around the rotary drill in a large area. During the concrete pouring stage of the pile foundation, the mud often overflows due to untimely diversion. The existing method of handling the mud at the hole mouth of the pile foundation is usually manual cleaning and leveling. When it seriously affects the construction environment on site, mechanical secondary cleaning is required.

[0038] The four anti-overflow plates 211 and the tooth plates 212 are snap-fitted and connected to the four side outer walls of the bottom plate 11, and the four anti-overflow plates 211 are tightly snap-fitted to each other. The four anti-overflow plates 211 form four-sided enclosures on the upper part of the bottom plate 11, and the four tooth plates 212 form four-sided enclosures on the lower part of the bottom plate 11; when the anti-overflow component 21 is installed, it is locked through the installation component 22, and the connecting column 221 is plugged from top to bottom into the connecting corners of two adjacent anti-overflow plates 211, the anti-overflow plate 211 is tightly snap-fitted with the snap-fitting groove 222, and the protrusion 223 is tightly snap-fitted with the sewage trough group 14 on the bottom plate 11, and then the pin 224 is inserted into the connecting column 221, the anti-overflow plate 211 and the protrusion 223 in turn, so as to achieve the locking of the bottom plate 11 and multiple anti-overflow plates 211, and the quickly detachable structure can make the transportation and transfer of the device more convenient, which is conducive to reducing transportation costs.

[0039] Reference Figure 1 and Figure 5The overflow prevention component 2 31 includes a horizontally retractable overflow prevention plate 2 313, and the top wall of the bottom plate 11 is slidably connected with an overflow prevention plate 2 313 corresponding to the overflow prevention plate 1 211, and a rubber layer is provided between the fixed section and the telescopic section of the overflow prevention plate 2 313 for sealing, and the side walls of the fixed sections of the four overflow prevention plates 2 313 close to each other are fixedly connected with a limiting frame 314, and the telescopic section of the overflow prevention plate 2 313 cooperates with the fixed section of the adjacent overflow prevention plate 2 313, and the side of the limiting frame 314 close to each other is in an arc shape, and the side walls of the four overflow prevention plates 2 313 away from each other are slidably connected with an inverted T-shaped sliding seat 1 312 up and down, and the sliding seat 1 312 and the top wall of the bottom plate 11 are hinged with an adjustment plate 311.

[0040] Reference Figure 1 , Figure 5 and Figure 6 The adjusting component 32 includes an inverted U-shaped part 324, and the middle part of the top wall of the anti-overflow plate 211 is fixedly connected with the inverted U-shaped part 324, and the two vertical sections of the inverted U-shaped part 324 are connected with a slide seat 2 322 for sliding up and down together, and the side wall of the slide seat 2 322 is rotatably connected with an adjusting ring 323, and the slide seat 2 322 and the inverted U-shaped part 324 are relatively fixed by plugging with a latch 2 325; a threaded rod 321 is fixedly connected to the upper part of the side wall of the vertical section of the slide seat 1 312, and the threaded rod 321 is threadedly connected to the corresponding adjusting ring 323, and a horizontally arranged U-shaped support member 326 is fixedly connected to the upper part of the side wall of the anti-overflow plate 211 close to the slide seat 1 312, and the support member 326 limits the corresponding slide seat 1 312.

[0041] Reference Figure 1 and Figure 7 The sealing assembly 33 includes a rubber plug 331, a rubber plug 331 is fixedly connected to the side wall of the second anti-overflow plate 313 near the telescopic section of the second anti-overflow plate 313, and a rubber plug 332 is connected to the side wall of the second anti-overflow plate 313 on which the limiting frame 314 is arranged through bolts and fits with the rubber plug 331 on the other second anti-overflow plate 313.

[0042] During the installation of the anti-overflow component 21, the adjustment plate 311 is in a nearly horizontal state. At this time, the anti-overflow plate 211 gradually approaches the threaded rod 321, and the threaded rod 321 slides through the slide seat 322. After the anti-overflow component 21 is installed, the position of the threaded rod 321 is adjusted by rotating the adjustment ring 323. During this process, the support member 326 limits the movement of the slide seat 312. The threaded rod 321 pulls the slide seat 312 to move close to the anti-overflow plate 211, and the slide seat 312 drives the anti-overflow plate 313 to move on the top wall of the bottom plate 11.

[0043] When the overflow plate 213 moves close to the overflow plate 1 211, the inclination angle of the adjustment plate 311 gradually increases from a near horizontal state, and at the same time, the change in the inclination angle of the adjustment plate 311 drives the horizontal section of the slide 1 312 to adaptively move upward on the overflow plate 213, and the vertical section of the slide 1 312 slides on the support 326, and the threaded rod 321 drives the slide 2 322 to slide upward on the vertical section of the inverted U-shaped part 324. When the overflow plate 213 and the limit frame 314 move to a position matching the size of the casing, the pin 2 325 is inserted into the slide 2 322 and the inverted U-shaped part 324 for position limitation.

[0044] Adjust the positions of the four anti-overflow plates 313 in turn counterclockwise. When the four anti-overflow plates 313 move to the appropriate positions corresponding to the protective tube, manually adjust the telescopic distances of the telescopic sections of the four anti-overflow plates 313 in the corresponding fixed sections to ensure that the four anti-overflow plates 313 fit each other. Finally, manually install the rubber plug 2 332 on the anti-overflow plate 313 close to the rubber plug 1 331 through bolts. The rubber plug 1 331 and the rubber plug 2 332 seal the gap between two adjacent anti-overflow plates 313.

[0045] After the device is assembled and adjusted, the sling is connected to the connecting column 221, and the entire device is lifted by the sling, adjusted to the top of the casing, and then gradually lowered to sleeve the device on the outside of the sleeve. The tooth plate 1 13 and the tooth plate 2 212 are inserted downward into the ground, and the mud collection operation can be carried out stably without manual soil covering around the device; and the tooth plate 1 13 and the tooth plate 2 212 play a double sealing role to prevent the mud from overflowing from the bottom of the device. It should be noted that the lower end of the limit frame 314 can be chamfered so that the device can be quickly sleeved on the outside of the casing.

[0046] The outer wall of the casing is in contact with the limit frame 314, and the anti-overflow plate 313 is supported in multiple directions by the limit frame 314, the casing, the adjustment plate 311, and the bottom plate 11. When the rotary drilling rig is used to drill a hole for the mud wall pile foundation, the mud is collected in the range enclosed by the four anti-overflow plates 313 and flows back into the pile foundation hole through the overflow groove on the casing to prevent the mud from spilling around the casing; the range enclosed by the four anti-overflow plates 313 is adjustable, which improves the practicality of the device.

[0047] When the space between the four overflow prevention plates 313 is filled with mud or the mud is spilled following the rotation radius of the rotary drilling rig, the overflow prevention plates 211 provided for enclosure on the outside can perform secondary mud collection and mud overflow prevention, thereby enhancing the collection effect of the device, ensuring safe and civilized construction on site, and preventing the entire construction site from becoming muddy.

[0048] Reference Figure 1-Figure 9The specific operating steps of the pile foundation hole mud collection device are as follows: first, the four overflow prevention plates 211 and the tooth plate 212 are assembled with the four side outer walls of the bottom plate 11, and the pin 224 is inserted into the connecting column 221, the overflow prevention plate 211 and the protrusion 223 in sequence to achieve the locking of the bottom plate 11 and the multiple overflow prevention plates 211; then, according to the diameter of the casing to be sleeved, the position of the adjustment plate 311 is adjusted by rotating the adjustment ring 323, and the position is limited by inserting the pin 2 325 into the slide seat 2 322 and the inverted U-shaped part 324; the blocking effect of the overflow prevention component 2 31 is increased by the blocking component 33.

[0049] The adjusted device is mounted on the outside of the casing from top to bottom through a sling, and four anti-overflow plates 313 collect the mud at the subsequent pile foundation holes to prevent overflow; the anti-overflow plate 211 for enclosure on the outside can perform secondary mud collection and mud overflow prevention, thereby enhancing the collection effect of the device.
