Description

A sampling structure for detecting quality of building rock and soil pile foundation

Technical Field

The utility model relates to the technical field of pile foundation sampling tools, in particular to a building rock soil pile foundation quality detection sampling structure.

Background Art

The foundation of a building, also called pile foundation, is the main load-bearing part of the building structure. The quality of the pile foundation is directly related to the safety and durability of the structure. Since the pile foundation needs to be buried below the rock and soil layer, it is a hidden project. Therefore, when conducting quality inspections, more professional inspection methods are usually used. Among them, the coring method of pile foundation is a more professional and commonly used inspection method.

However, when the existing pile foundation adopts the coring method, a drilling machine is usually used to drill holes from top to bottom on the top of the pile foundation, and the drilling machine is usually fixed using a tripod. Since the number and position of sampling holes for pile foundations with different pile diameters are different, and the sampling point of a single-hole pile foundation needs to be 10 to 15 centimeters away from the center of the pile foundation, and when the drilling position needs to be adjusted, the position of the tripod needs to be frequently adjusted, which is inconvenient for the detection and sampling personnel to use; in addition, when drilling holes for sampling of the pile foundation, the operation of the drilling machine will generate a lot of splashing of mud or concrete debris, and since the detection personnel need to observe the sampling situation at a position close to the drilling hole, the detection personnel are very likely to be injured by the splashing debris, resulting in low safety in the pile foundation detection sampling process.

As shown in Figures 1 to 4, the sampling structure for detecting the quality of building rock and soil pile foundations in this embodiment includes a vertical cylinder 1, a horizontal plate 4 is fixedly connected to the top of the vertical cylinder 1, a movable block 3 is movably sleeved on the outer wall of the horizontal plate 4, a fastening bolt 2 is penetrated through the movable thread at the top of the movable block 3, an electric push rod 5 is fixedly installed on the other side of the bottom end of the movable block 3, a vertical pole 7 is fixedly connected to one side of the bottom end of the movable block 3, a slide plate 6 is movable sleeved on the outer side of the vertical pole 7, a rotating motor 8 is provided on one side of the slide plate 6, a sampling drill bit 18 is engaged with the output end of the rotating motor 8, an annular groove 15 is provided on the top of the inner wall of the vertical cylinder 1, a slider 16 is slidably connected to the inner wall of the annular groove 15, a scraper 12 is fixedly connected to the bottom end of the slider 16, a bottom ring 10 is fixedly connected to the outer wall of the bottom end of the vertical cylinder 1, and a plurality of circular holes 11 are provided on the top of the bottom ring 10.

Specifically, openings 14 are provided at the top and bottom of the vertical cylinder 1, and the two openings 14 are of the same size. At the same time, the diameter of the vertical cylinder 1 is the same as the pile diameter of the more common pile foundation on the market, so that the vertical cylinder 1 can be directly placed on the surface of the pile foundation, which is easier to maintain stability than a tripod and is also convenient to install and fix on the top of the pile foundation. The cross plate 4 and the vertical cylinder 1 are an integrated structure, so that the cross plate 4 can increase the support for the movable block 3. The movable block 3 can slide back and forth on the cross plate 4, thereby driving the position of the sampling drill bit 18 at the bottom to be flexibly adjusted and changed, which is convenient for the detection and sampling personnel to use. After the fastening bolts 2 are tightened, the movable block 3 can be fixed in the position of the cross plate 4, so that the movable block 3 can maintain the stability of the structure such as the vertical pole 7. The electric push rod 5 can push the rotating sampling drill bit 18 to move to the top of the pile foundation after power is turned on, thereby realizing the drilling and coring of the pile foundation. The vertical pole 7 can enable the electric push rod 5 to push the rotating motor 8 downward The invention has better stability, which is conducive to the rotating motor 8 driving the sampling drill bit 18 to drill a hole at the top of the pile foundation. The annular groove 15 can make the slider 16 rotate in the horizontal direction with the center of the annular groove 15 as the center of the circle in the vertical tube 1. The scraper 12 is made of silicone material, which is wear-resistant and not easy to deform. When the slider 16 slides along the annular groove 15, it can drive the scraper 12 to scrape against the inner wall of the vertical tube 1, and the muddy water and debris splashed on the inner wall of the vertical tube 1 are quickly cleaned from the inner wall of the vertical tube 1. The bottom ring 10 can increase the contact area between the bottom end of the vertical tube 1 and the top surface of the pile foundation, so that the vertical tube 1 is more stable when placed on the top of the pile foundation. The inner diameter of the circular hole 11 is larger than the outer diameter of the steel bar exposed at the top of the pile foundation, so that when the diameter of the bottom ring 10 is the same as the pile diameter of the pile foundation, the steel bar on the pile foundation can be inserted into the corresponding circular hole 11 on the bottom ring 10, so that the bottom ring 10 is temporarily fixed to the steel bar exposed at the top of the pile foundation, thereby increasing the stability of the sampling structure.

Furthermore, a rubber plate 9 is embedded in the top of the transverse plate 4, the fastening bolts 2 are movably connected to the rubber plate 9, the movable block 3 is slidably connected to the rubber plate 9, and the movable block 3 is movably connected to the transverse plate 4 through the fastening bolts 2. The rubber plate 9 can increase the friction with the bottom end of the fastening bolts 2, so that the fastening bolts 2 can better fix the movable block 3 on the transverse plate 4.

Furthermore, a connecting plate 17 is fixedly connected to one side wall of the slide plate 6, and the rotating motor 8 is fixedly installed on the top of the connecting plate 17. The connecting plate 17 can connect the slide plate 6 with the rotating motor 8, thereby realizing the push of the rotating motor 8 by the electric push rod 5, so that the sampling drill bit 18 can smoothly drill toward the top of the pile foundation.

Furthermore, the output end of the electric push rod 5 is fixedly connected to the top of the slide plate 6, and the rotating motor 8 is slidingly connected to the vertical pole 7 through the slide plate 6 and the electric push rod 5. After the external power supply is turned on, the rotating motor 8 can drive the sampling drill bit 18 to rotate at the bottom of the connecting plate 17, thereby realizing the movement of the sampling drill bit 18 to the top of the pile foundation.

Furthermore, the scraper 12 is movably connected to the vertical cylinder 1 through the slider 16. When the slider 16 slides along the annular groove 15, the scraper 12 can rotate in contact with the inner wall of the vertical cylinder 1, so that the muddy water and debris splashed and condensed on the inner wall of the vertical cylinder 1 can be cleaned in time.

Furthermore, the bottom end of the vertical pole 7 is fixedly connected with a ground mat 13, which can increase the connection relationship between the bottom end of the vertical pole 7 and the top of the pile foundation, so that the vertical pole 7 can contact the top of the pile foundation, so that the top and bottom ends of the vertical pole 7 can be fixed, thereby increasing the stability of the vertical pole 7 itself.

Furthermore, an opening 14 is provided at the bottom end of the vertical tube 1, and the ground mat 13 is movably connected to the opening 14. The setting of the opening 14 allows the top of the pile foundation to be exposed in the vertical tube 1, which is beneficial for the direct contact between the sampling drill bit 18 and the pile foundation.

The method of using this embodiment is as follows: when using the sampling structure for detecting the quality of the building rock soil pile foundation, it is necessary to first place the bottom ring 10 on the structure according to the pile diameter of the pile foundation. If the diameter of the bottom ring 10 is the same as the pile diameter of the pile foundation, the exposed steel bars on the sampled pile foundation can be matched with the circular holes 11 on the bottom ring 10, so that the steel bars are inserted into the circular holes 11, so that the bottom ring 10 is fixed to the exposed steel bars on the top of the pile foundation. Then, the structure can be connected to an external power supply so that the electric push rod 5 and the rotating motor 8 are started. At this time, the electric push rod 5 will push the slide plate 6 downward along the vertical pole 7. Move, and the rotating motor 8 will drive the sampling drill bit 18 to rotate, and driven by the slide plate 6 and the connecting plate 17, it will also move along the vertical rod 7 to the top of the pile foundation to drill and coring the top of the pile foundation. When the sampling drill bit 18 drills the top of the pile foundation, the muddy water and debris splashed from the drill hole will be blocked by the vertical tube 1. After completing the use of this structure, the slider 16 can be pushed to slide along the annular groove 15, driving the scraper bar to rotate along the inner wall of the vertical tube 1, so that the scraper bar can promptly scrape the muddy water and debris splashed to the inner wall of the vertical tube 1 away from the inner wall of the vertical tube 1.
