Description

Technical Field

[0001] The utility model relates to the field of cement-stabilized crushed stone water-permeable base performance detection, in particular to a cement-stabilized crushed stone water-permeable base performance detection device. Background Art

[0002] Cement-stabilized crushed stone permeable base is a new type of pavement base structure, and its performance has an important impact on the durability and service life of the pavement. Cement-stabilized crushed stone uses graded crushed stone as aggregate, and uses a certain amount of cementitious materials and sufficient mortar volume to fill the gaps in the aggregate and compact it into a permeable base. As disclosed in the patent announcement number CN219301986U, in order to ensure the performance of the cement-stabilized crushed stone permeable base, it is necessary to take core samples for testing.

[0003] The compacted cement-stabilized gravel permeable base is relatively hard, and the commonly used coring sampling equipment needs to be injected with water during coring to protect the drill. After drilling through the permeable base, the injected water will flow into the sampling port and cause an impact. Utility Model Content

[0004] The utility model aims to provide a cement stabilized crushed stone permeable base performance detection device to solve the above technical problems.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a cement-stabilized crushed stone permeable base performance detection device, including a base plate, a limit column, a cross beam, a turntable, a threaded column, a limit beam, a driving water injection mechanism, a core barrel, and a water recovery structure. The limit columns are respectively fixed in the middle of the top of the left and right base plates, and the left and right ends of the cross beam are respectively connected to the upper parts of the two limit columns. The turntable is rotatably connected to the middle of the top of the cross beam, the threaded column is connected to the bottom of the turntable through the cross beam, the middle part of the limit beam is threadedly connected to the threaded column, and the left and right parts of the limit beam are respectively slidably connected to the limit columns, the driving water injection mechanism is installed in the middle of the front end of the limit beam, the core barrel is installed at the bottom of the driving water injection mechanism, and the water recovery structure is installed at the rear of the base plate.

[0006] Based on the above technical scheme, the water recovery structure includes a mounting plate, a water tank, a pump, a hose, an adsorption cover, a sliding column, and a sliding hole. The mounting plate is connected to the rear of the left and right base plates, the water tank is installed at the rear of the top of the mounting plate, the pump is installed at the front end of the water tank, the rear of the hose is connected to the pump, the adsorption cover is connected to the front end of the hose, and the middle part of the adsorption cover is or is slidably connected to the core barrel, the sliding column is fixed to the rear of the side end of the adsorption cover, the sliding hole is opened in the middle of the front end of the mounting plate, and the sliding hole is slidably connected to the sliding column.

[0007] Based on the above technical solution, the pump absorbs and recovers the water flowing out of the core barrel through the absorption cover.

[0008] Compared with the prior art, the utility model has the following advantages: the utility model installs a water recovery structure at the coring sampling device of the cement-stabilized gravel permeable base layer, so that during the process of drilling and coring water injection, a pump is simultaneously used to absorb the injected water, thereby avoiding the problem of water flowing into the sampling port after the drilling is successful and causing an impact.

DETAILED DESCRIPTION

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figures 1 to 3 As shown, a cement-stabilized crushed stone permeable base performance detection device includes a base plate 1, a limiting column 2, a cross beam 3, a turntable 4, a threaded column 5, a limiting beam 6, a driving water injection mechanism 7, a core barrel 8, and a water recovery structure 9. The limiting columns 2 are fixed in the middle of the top of the left and right base plates 1 respectively, and the left and right ends of the cross beam 3 are respectively connected to the upper parts of the two limiting columns 2. The turntable 4 is rotatably connected to the middle of the top of the cross beam 3. The threaded column 5 is connected to the bottom of the turntable 4 through the cross beam 3. The middle part of the limiting beam 6 is threadedly connected to the threaded column 5, and the left and right parts of the limiting beam 6 are respectively slidably connected to the limiting column 2. The driving water injection mechanism 7 is installed in the middle of the front end of the limiting beam 6, the core barrel 8 is installed at the bottom of the driving water injection mechanism 7, and the water recovery structure 9 is installed at the rear of the base plate 1.

[0015] The water recovery structure 9 includes a mounting plate 10, a water tank 11, a pump 12, a hose 13, an adsorption cover 14, a sliding column 15, and a sliding hole 16. The mounting plate 10 is connected to the rear of the left and right base plates 1, the water tank 11 is installed at the rear of the top of the mounting plate 10, the pump 12 is installed at the front end of the water tank 11, the rear of the hose 13 is connected to the pump 12, the adsorption cover 14 is connected to the front end of the hose 13, and the middle part of the adsorption cover 14 is or is slidably connected to the core barrel 8, the sliding column 15 is fixed to the rear of the side end of the adsorption cover 14, the sliding hole 16 is opened in the middle of the front end of the mounting plate 10, and the sliding hole 16 is slidably connected to the sliding column 15.

[0016] The pump 12 absorbs and recovers the water flowing out of the core tube 8 through the absorption cover 14 .

[0017] The working principle of the utility model is as follows: when in use, the equipment is pushed to the sampling location, the threaded column 5 is rotated by the turntable 4, and the limit beam 6 is forced to slide downward along the limit column 2 to drive the water injection mechanism 7. The core tube 8 is against the cement-stabilized gravel permeable base layer through the adsorption cover 14, and the water injection mechanism 7 is started to rotate the core tube 8 and inject water into it for coring sampling. The pump 12 absorbs and recovers the water flowing out of the core tube 8 through the adsorption cover 14 and enters the water tank 11 to prevent water from flowing into the hole after the drilling is successful.

[0018] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
