This process is crucial to assessing the quality of the land and ensuring the safety of the building, as it helps engineers understand the properties of the soil and thus decide how to construct the building.

[0003] When the existing soil sampling device for building construction planning samples the ground soil, the sampling drill bit is pulled out from the ground. Due to the gravel particles contained in the ground soil, the sampling drill bit is easily stuck in the ground and difficult to be pulled out. It takes a lot of effort to pull the sampling drill bit out of the ground. Therefore, improvement is needed. Utility Model Content

[0004] In order to overcome the above-mentioned defects, the utility model provides a soil sampling device for building construction planning, which solves the problem that when the existing soil sampling device for building construction planning is sampling the ground soil, the sampling drill bit is easily stuck on the ground, and a lot of effort is required to pull the sampling drill bit out of the ground.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a soil sampling device for building construction planning, comprising a fixed pipe, three groups of fixed protrusions are fixedly installed at equal angles on the top and bottom of the surface of the fixed pipe, and a support frame is provided between two groups of opposite fixed protrusions, three groups of mounting columns are fixedly installed at equal angles on the bottom of the fixed pipe, and limiting rings are fixedly installed on the tops of the three groups of mounting columns, and sliding pipes are slidably installed on the surfaces of the three groups of mounting columns;

[0006] A lifting spring is provided on the surface of the mounting column at the bottom of the sliding tube, a sampling drill bit is provided inside the sliding tube, and the top of the sampling drill bit passes through a limiting ring and the top of the fixed tube, three groups of slots are provided at equal angles on the top of the fixed tube surface, and the slots correspond to the fixed protrusions, and a fixed pressure ring is provided on the top of the fixed tube.

[0007] As a further solution of the utility model: two groups of fixing slots are provided on one side of the support frame, and the fixing slots correspond to the fixing protrusions, and a fixing nail is provided at the bottom of one end of the support frame away from the fixing slots.

[0008] As a further solution of the utility model: three groups of slide grooves are provided at equal angles on the surface of the fixed tube, and three groups of limit sliders are fixedly installed at equal angles on the surface of the sliding tube, and the limit sliders pass through the slide grooves.

[0009] As a further solution of the utility model: a retaining ring is fixedly installed on the surface of the sampling drill bit located on the top of the limiting ring, and a hand wheel is fixedly installed on the top of the sampling drill bit through a fixed tube.

[0010] As a further solution of the utility model: three groups of arc grooves are provided at equal angles on the top of the fixed pressure ring, fixing bolts are provided inside the arc grooves, and the fixing bolts pass through the arc grooves and are connected to the fixing pipes.

[0011] As a further solution of the utility model: a second slot is provided on the surface of the fixed pressure ring between the two groups of arc grooves, and the second slot corresponds to the first slot.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The soil sampling device for building construction planning is provided with a sliding tube, a lifting spring and a sampling drill bit. After the fixed tube is placed at the construction sampling position, the sampling drill bit is inserted into the sliding tube through the top of the fixed tube and the limit ring, so that the retaining ring is stuck on the top of the sliding tube, and the sampling drill bit is pressed downward to rotate, so that the sampling drill bit is extended into the ground to sample the soil. After the sampling drill bit completes the sampling, the hand wheel is released and the hand wheel is rotated in the opposite direction. Under the rebound action of the lifting spring, the sliding tube and the sampling drill bit are lifted away from the ground, thereby reducing the effort consumed by the operator to remove the sampling drill bit from the ground.

[0014] 2. The soil sampling device for building construction planning is provided with a fixed protrusion, a support frame, a fixed pressure ring and a fixed bolt. The fixing bolt is loosened, and the fixed pressure ring is rotated to make slot one correspond to slot two.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a soil sampling device for building construction planning, comprising a fixed tube 1, three groups of fixed protrusions 2 are fixedly installed at equal angles on the top and bottom of the surface of the fixed tube 1, and a support frame 3 is provided between two groups of opposite fixed protrusions 2. Because the fixed protrusions 2 are provided, the support frame 3 is clamped on the surface of the corresponding fixed protrusion 2 to ensure that the support frame 3 will not be misaligned or deflected when it is fixed on the surface of the fixed tube 1;

[0022] Two groups of fixed slots 301 are provided on one side of the support frame 3, and the fixed slots 301 correspond to the fixed protrusions 2. A fixing nail 302 is provided at the bottom of one end of the support frame 3 away from the fixing slots 301. By providing the support frame 3, after the fixed pipe 1 is placed at the designated position for construction sampling, the fixing nail 302 is controlled to penetrate into the ground, so that the three groups of support frames 3 can support the fixed pipe 1 to prevent the fixed pipe 1 from tilting and deflecting during sampling.

[0023] Three groups of mounting columns 4 are fixedly installed at equal angles on the bottom of the fixed pipe 1, and limit rings 5 ​​are fixedly installed on the tops of the three groups of mounting columns 4. Sliding tubes 6 are slidably installed on the surfaces of the three groups of mounting columns 4. The sliding tubes 6 ensure that when the sampling drill bit 10 is pressed down to sample the ground soil, the sampling drill bit 10 can move vertically inside the sliding tube 6 without tilting or deflecting with the fixed pipe 1.

[0024] Three groups of slide grooves 7 are provided at equal angles on the surface of the fixed tube 1, and three groups of limit sliders 8 are fixedly installed at equal angles on the surface of the sliding tube 6, and the limit sliders 8 pass through the slide grooves 7. By providing the limit sliders 8, when the sliding tube 6 is controlled to slide up and down inside the fixed tube 1, the limit sliders 8 slide inside the slide grooves 7, thereby limiting the sliding range of the sliding tube 6.

[0025] A lifting spring 9 is provided on the surface of the mounting column 4 at the bottom of the sliding tube 6. Due to the lifting spring 9, the sliding tube 6 is lifted up under the rebound effect of the lifting spring 9, so that the sampling drill bit 10 is lifted up by the sliding tube 6 away from the ground, which facilitates the sampling drill bit 10 to be taken out from the ground;

[0026] A sampling drill bit 10 is provided inside the sliding tube 6, and the top end of the sampling drill bit 10 passes through the limiting ring 5 and the top of the fixed tube 1. The surface of the sampling drill bit 10 is located on the top of the limiting ring 5 and is fixedly installed with a retaining ring 11. The top end of the sampling drill bit 10 passes through the fixed tube 1 and is fixedly installed with a handwheel 12. By providing the retaining ring 11, the sampling drill bit 10 is pressed down so that the retaining ring 11 is stuck on the top of the sliding tube 6, thereby ensuring that the sliding tube 6 can lift the sampling drill bit 10.

[0027] The top of the surface of the fixed tube 1 is provided with three groups of slots 13 at equal angles, and the slots 13 correspond to the fixed protrusions 2, and a fixed pressure ring 14 is provided on the top of the fixed tube 1. The surface of the fixed pressure ring 14 is provided with a slot 2 16 between the two groups of arc grooves 15, and the slot 2 16 corresponds to the slot 1 13. Since the slot 1 13 and the slot 2 16 are provided, after the slot 1 13 and the slot 2 16 correspond, it is convenient to pass the support frame 3 through the slot 1 13 and the slot 2 16 and clamp it on the corresponding surface of the fixed protrusion 2.

[0028] Three groups of arc grooves 15 are provided at equal angles on the top of the fixed pressure ring 14, and a fixing bolt 17 is provided inside the arc groove 15, and the fixing bolt 17 passes through the arc groove 15 and is connected to the fixed pipe 1. Because the fixed pressure ring 14 is provided, the fixing bolt 17 is loosened to disengage from the arc groove 15, and the fixed pressure ring 14 is rotated to make the slot 2 16 and the slot 1 13 misaligned, and then the fixing bolt 17 is tightened to fix the support frame 3 to the bottom of the fixed pressure ring 14.

[0029] The working principle of the utility model is:

[0030] After the screwdriver is in the state of being moved to the left, the screwdriver 1 is in the state of being moved to the right, and the screwdriver 1 is in the state of being moved to the right, so that the screwdriver 1 is in the state of being moved to the right, and the screwdriver 1 is in the state of being moved to the right, so that the screwdriver 1 is in the state of being moved to the right, and the screwdriver 1 is in the state of being moved to the right, so that the screwdriver 1 is in the state of being moved to the right, and the screwdriver 1 is in the state of being moved to the right, so that the screwdriver 1 is in the state of being moved to the right, and the screwdriver 1 is in the state of being moved to the right, so that the screwdriver 1 is in the state of being moved to the right, and the screwdriver 1 is in the state of being moved to the right
