Description

Technical Field

[0001] The utility model relates to the technical field of rock and soil sampling, in particular to a rock and soil engineering survey sampling device. Background Art

[0002] Soil sampling plays a very important role in the formulation of construction plans and construction quality. Therefore, soil sampling and analysis is an essential step before various engineering constructions.

[0003] At present, in the soil sampling device with application number CN201820146592.1, a jack is fixed on the soil ground, and the drill rig is powered on to drive the drill rod to drill into the soil. The drill rod is located inside the sleeve, and the upper part of the sleeve is connected to the drill rod through a sleeve. The sleeve is drilled into the soil with the drill rod. When the baffle on the sleeve contacts the support frame, the sleeve is rotated to allow the drill rod to move along the sleeve, and the soil sampler continues to extend downward. When the soil sampler drills into a certain depth, the drilling rig stops the sampling device and starts sampling.

[0004] However, the existing soil sampling device also has the following defects:

[0005] 1. The soil sampling device is not firmly anchored to the ground, and the anchoring effect is poor, which causes vibration and deviation during the sampling process, causing inconvenience to the soil sampling work;

[0006] 2. The soil sampling device is tilted due to the uneven ground, resulting in a large error in the soil sampling position. Utility Model Content

[0007] In view of the above-mentioned deficiencies in the prior art, the utility model provides a geotechnical engineering survey sampling device, which solves the problems that the existing soil sampling device is unstable in anchoring to the ground and the soil sampler is prone to tilt and offset.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] Provided is a geotechnical engineering survey sampling device, which includes a support ring seat, a plurality of legs are arranged on the circumference of the support ring seat, and positioning pieces for anchoring on the ground are arranged at the lower ends of the legs, a mounting ring seat is arranged above the support ring seat, and a plurality of adjusting pieces for adjusting the horizontality of the mounting ring seat are arranged between the mounting ring seat and the support ring seat, a sampler is arranged on the mounting ring seat, and the sampler includes a fixing plate fixed on the mounting ring seat, a vertical sampling screw rod is passed through the fixing plate, and the sampling screw rod is threadedly matched with the fixing plate, and a soil sampler for facilitating sampling is arranged at the lower end of the sampling screw rod.

[0010] Furthermore, the positioning member includes a cone cylinder, a cone head is provided at the lower end of the cone cylinder for easy insertion into the soil, an anchoring mechanism is provided inside the cone cylinder, the anchoring mechanism includes a plurality of anchoring holes evenly arranged in the circumferential direction of the side wall of the cone cylinder, and each anchoring hole is located in the radial direction of the cone cylinder, an anchoring pin is movably provided in the anchoring hole, and the anchoring mechanism also includes a pushing member for pushing the anchoring pin to move outward.

[0011] Furthermore, a cavity connected to the inner ends of several anchor holes is provided in the conical cylinder, and the pushing member includes a pushing cone arranged in the cavity, the conical surface of the pushing cone abuts against the inner end of the anchor pin, the pushing cone is connected to the anchor screw, and a threaded hole matching the thread of the anchor screw is provided in the middle of the conical cylinder.

[0012] Furthermore, an abutment joint is provided at the inner end of the anchor pin, a clamping ring is provided at the outer end of the anchor hole, a return spring is sleeved on the anchor pin between the clamping ring and the abutment joint, and two ends of the return spring are respectively in abutment with the clamping ring and the abutment joint.

[0013] Furthermore, each adjusting member includes an adjusting screw rod vertically passed through the support ring seat and threadedly matched with the support ring seat. Several adjusting screw rods are evenly arranged on the circumference of the support ring seat, and the upper ends of several adjusting screw rods are connected to the mounting ring seat through spherical hinges.

[0014] Furthermore, the upper end of the sampling screw rod and the lower end of the adjusting screw rod are both provided with a turntable which is easy to rotate.

[0015] Furthermore, one end of each of the plurality of legs is pivotally connected to the support ring seat.

[0016] The beneficial effects of the utility model are:

[0017] 1. This solution provides reliable support for the support ring seat through a number of legs, and inserts the cone on each leg into the ground soil. By rotating the anchor screw, the pushing cone can be driven to move along the axial direction of the cone. At the same time, the conical surface of the pushing cone can push a number of anchor pins to move along the radial direction of the cone, so that the outer end of the anchor pin protrudes from the outer wall of the cone and extends into the soil, thereby locking the cone in the ground soil, thereby enhancing the anchoring effect of the support ring seat and making the support ring seat less prone to vibration and displacement.

[0018] 2. This solution can adjust the horizontality of the mounting ring seat by rotating a number of adjusting screw rods, so that when the support ring seat is tilted and offset due to the cone being anchored on uneven ground soil, the mounting ring seat can still remain horizontal to facilitate accurate sampling by the sampler.

DETAILED DESCRIPTION

[0022] The specific implementation methods of the utility model are described below to facilitate technical personnel in this technical field to understand the utility model, but it should be clear that the utility model is not limited to the scope of the specific implementation methods. For ordinary technical personnel in this technical field, as long as various changes are within the spirit and scope of the utility model defined and determined by the attached claims, these changes are obvious, and all utility model creations using the concept of the utility model are protected.

[0023] like Figure 1 and Figure 2 As shown, the geotechnical engineering survey sampling device of the present scheme comprises a support ring seat 1, and four legs 2 are evenly arranged in the circumferential direction of the outer edge of the support ring seat 1, and one end of the four legs 2 is pivotally connected to the support ring seat 1 to facilitate the rotation and storage of the legs 2; the other end of the leg 2 is provided with a positioning member 3 for anchoring on the ground, and the positioning member 3 comprises a cone cylinder 8, and the lower end of the cone cylinder 8 is provided with a cone head 9 that is convenient for inserting into the soil, and an anchoring mechanism is provided in the cone cylinder 8, and the anchoring mechanism comprises a plurality of anchoring holes 10 evenly arranged in the circumferential direction of the side wall of the cone cylinder 8, and each anchoring hole 10 is located in the radial direction of the cone cylinder 8, and an anchoring pin 11 is movably provided in the anchoring hole 10, and the anchoring mechanism also comprises a pushing member for pushing the anchoring pin 11 to move outward.

[0024] During the design, a cavity 12 connected to the inner ends of several anchor holes 10 is provided in the conical cylinder 8, and the pushing member includes a pushing cone 13 arranged in the cavity 12. The conical surface of the pushing cone 13 abuts against the inner end of the anchor pin 11, and the pushing cone 13 is connected to the anchor screw 14. A threaded hole 15 threadedly matched with the anchor screw 14 is provided in the middle of the conical cylinder 8; an abutment 16 is provided at the inner end of the anchor pin 11, and a retaining ring 17 is provided at the outer end of the anchor hole 10. A reset spring 18 is sleeved on the anchor pin 11 between the retaining ring 17 and the abutment 16, and the two ends of the reset spring 18 abut against the retaining ring 17 and the abutment 16 respectively.

[0025] The present invention provides reliable support for the support ring seat 1 by means of a plurality of legs 2, and inserts the cone 8 on each leg 2 into the ground soil. By rotating the anchor screw 14, the pushing cone 13 can be driven to move axially along the cone 8. At the same time, the conical surface of the pushing cone 13 can push a plurality of anchor pins 11 to move radially along the cone 8, so that the outer ends of the anchor pins 11 protrude from the outer wall of the cone 8 and extend into the soil, thereby locking the cone 8 in the ground soil, thereby enhancing the anchoring effect of the support ring seat 1 and making the support ring seat 1 less prone to vibration and displacement. At the same time, after the soil sampling is completed, the pushing cone 13 can be reset by rotating the anchor screw 14 in the opposite direction, and the anchor pin 11 can automatically shrink into the anchor hole 10 under the action of the reset spring 18, so as to release the lock between the cone 8 and the ground soil.

[0026] In particular, the outer end of the anchor pin 11 of the present solution is slidably fitted with the inner wall of the clamp ring 17, so that the clamp ring 17 can play a limiting and guiding role for the anchor pin 11, so that the anchor pin 11 can only slide along the extension direction of the anchor hole 10, and avoid the anchor pin 11 from being deflected in other directions under the action of the pushing cone 13;

[0027] A mounting ring seat 4 is arranged above the support ring seat 1, and four adjusting parts for adjusting the horizontality of the mounting ring seat 4 are arranged between the mounting ring seat 4 and the support ring seat 1. A sampler is arranged on the mounting ring seat 4, and the sampler includes a fixed plate 5 fixed on the mounting ring seat 4, a vertical sampling screw 6 is passed through the fixed plate 5, and the sampling screw 6 is threadedly matched with the fixed plate 5, and a soil sampler 7 for facilitating sampling is arranged at the lower end of the sampling screw 6; by rotating the sampling screw 6, the soil sampler 7 can be screwed in vertically downward and extended into the soil to a certain depth for sampling; after the soil sampling is completed, the soil sampler 7 can be screwed out of the soil by rotating the sampling screw 6 in the opposite direction. In particular, the soil sampler 7 of this scheme can adopt the screw-in soil sampler in the prior art, so its internal structure is no longer described.

[0028] During the design, each adjusting member includes an adjusting screw 19 which is vertically penetrated through the support ring seat 1 and threadedly matched with the support ring seat 1. Four adjusting screws 19 are evenly arranged on the circumference of the support ring seat 1, and the upper ends of the four adjusting screws 19 are connected to the mounting ring seat 4 through a spherical hinge 20. Through the rotational cooperation of the four adjusting screws 19, the horizontal adjustment of the mounting ring seat 4 can be achieved, so that in this scheme, when the support ring seat 1 is tilted and offset due to the anchoring of the cone cylinder 8 on the uneven ground soil, the mounting ring seat 4 can still maintain a horizontal state to facilitate accurate sampling by the sampler.

[0029] Preferably, the upper end of the sampling screw rod 6 and the lower end of the adjusting screw rod 19 are both provided with a rotating disk 21 for easy rotation.
