[0002] Municipal engineering generally refers to infrastructure construction, including various public transportation facilities, water supply, drainage, gas, urban flood control, environmental sanitation, and lighting infrastructure construction in urban construction, including geotechnical engineering investigation.

[0003] The purpose of geotechnical engineering investigation is to use testing means and methods to conduct investigations, research, and analysis and judgment on the construction site, study the geological conditions for building various engineering structures and the impact of construction on the natural geological environment; study the measures to ensure the foundation strength, stability, and prevent inadmissible deformation when the foundation, foundation, and superstructure work together; propose the bearing capacity of the foundation, provide engineering geological and geotechnical data required for foundation design and construction, and necessary foundation reinforcement, and geotechnical investigation sampling is an important process in geotechnical engineering investigation, and the quality of sampling directly affects the accuracy of the investigation.

[0004] Geotechnical investigation sampling needs to obtain geotechnical samples at different depths. The Chinese utility model patent with the publication number CN217542471U discloses an investigation sampling device for municipal engineering. Its working principle is: first, move the device to the required working position, then fix the frame at the working position through the ground nails on the support feet, drive the screw rod to rotate through the operation of the servo motor, so that the drill barrel moves linearly downward to the required working position, and at the same time, drive the motor to work to drive the drill bit to rotate at high speed. When the drill barrel reaches the required position, remove the baffle from the drill barrel through the handle, drive the electric push rod to work to push the transmission plate to move in the limit chute, so that the push rod pushes the sampling box to move out of the drill barrel and insert into the soil layer for sampling. After sampling, the electric push rod works to reset, so that the sampling box returns to the drill barrel, then install the baffle on the drill barrel, and the servo motor works to make the drill barrel rise and reset. After removing the baffle, take out the soil layer in the sampling box.

[0005] However, the working depth of the above device is limited by the stroke of the screw rod, which is not convenient for dealing with scenarios with different depth requirements. Content of the Utility Model

[0048] The present utility model provides a surveying device for municipal engineering. The position of the cutter head is driven by a moving mechanism. The moving mechanism drives the cutter head to rotate so as to extend into the rock and soil. Moreover, the rotating member, the extension member, and the cutter head are detachably connected by a first clamping member and a second clamping member, facilitating the stacking of two or more extension members to obtain samples at deeper positions.

[0049] The following provides a detailed description of a surveying device for municipal engineering of the present application through the following embodiments.

[0050] In this embodiment, as Figures 1 to 3 shown, the surveying device for municipal engineering includes: a frame 1;

[0051] A movable plate 2, slidably disposed on the frame 1;

[0052] A moving mechanism 3, disposed on the frame 1 and connected to the movable plate 2, for driving the movable plate 2 to move;

[0053] A rotating member 4, rotatably disposed on the movable plate 2 and provided with a first card slot;

[0054] An extension member 5, provided with a second card slot and a third card slot at both ends respectively;

[0055] A first clamping member 6, clamped in the first card slot and the second card slot, for connecting the rotating member 4 and the extension member 5;

[0056] A cutter head 7, provided with a fourth card slot;

[0057] A second clamping member 9, clamped in the third card slot and the fourth card slot, for connecting the extension member 5 and the cutter head 7;

[0058] A driving mechanism 8, disposed on the movable plate 2 and connected to the rotating member 4, for driving the rotating member 4 to rotate.

[0059] In this technical solution, for the convenience of description, the frame body 1 is placed vertically. The frame body 1 is provided with an upper fixing plate and a lower fixing plate. Four guide posts are arranged between the two fixing plates. The movable plate 2 is provided with four guide holes adapted to the four guide posts, so that the movable plate 2 can slide reciprocally within the frame body 1. The moving mechanism 3 is a chain or belt driven by a motor, which is fixed on the left side of the frame body 1, arranged vertically, and fixedly connected to the movable plate 2.

[0060] The rotating member 4 is a circular tubular member, which is rotatably arranged vertically on the movable plate 2. The driving mechanism 8 is fixed on the upper side of the movable plate 2. The driving mechanism 8 is a gear set driven by a motor. One gear is coaxially fixed on the outer side of the rotating member 4, and the other gear is fixed on the output shaft of the motor of the driving mechanism 8. The lengthening member 5 and the cutter head 7 are both hollow tubular members. A plurality of fan-shaped blade parts 701 are arranged on the circumferential bottom surface of the cutter head 7.

[0061] The first card slot is a non-through T-shaped groove arranged at the lower end of the movable plate 2. The second card slot is a through inverted T-shaped groove arranged at the upper end of the lengthening member 5. The third card slot is a non-through T-shaped groove arranged at the lower end of the lengthening member 5. The fourth card slot is a through inverted T-shaped groove arranged at the upper end of the cutter head 7. The sizes of the first card slot to the fourth card slot are all equal. The first engaging member 6 and the second engaging member 9 are both adapted I-shaped sheet members. When they are correspondingly engaged in the aforementioned card slots, the forward and reverse rotations of the rotating member 4 can synchronously drive the forward and reverse rotations of the cutter head 7 through the lengthening member 5.

[0062] In some technical solutions, the ends of the rotating member 4 and the lengthening member 5 close to each other are set as T-shaped surfaces. On the one hand, it is convenient for the inner side wall to internally support the first engaging member 6 to prevent the first engaging member 6 from sliding into the lengthening member 5. On the other hand, it is convenient for subsequent setting of the ring piece 11 to surround and fix the outer side surface of the first engaging member 6, so that the first engaging member 6 is stably fixed in the first card slot and the second card slot. Further, the structures at the third card slot and the fourth card slot are the same as those at the first card slot and the second card slot.

[0063] In some other technical solutions, the first engaging member 6 and the second engaging member 9 are provided with circular protrusions, which is convenient for their disassembly.

[0064] It should be noted that during actual use, the surveying device can be set obliquely, horizontally or inverted, and the orientation during use can be adjusted and fixed according to needs.

[0070] In this technical solution, the extension member 5 is provided with two, the first card slot to the fourth card slot are all provided with four, and correspondingly the first engaging member 6 is provided with eight. By setting different numbers of extension members 5, the cutter head 7 can be extended into the rock and soil by different distances, which is convenient for use.

[0071] In some technical solutions, the extension member 5 is provided with three or four.

[0072] In this embodiment, one end of the extension member 5 close to the second card slot is provided with an annular groove, a spring 10 is arranged at the annular groove, the spring 10 is fixedly provided with an annular plate 11, and the annular plate 11 is used to cover the second card slot.

[0073] In this technical solution, the outer side surface of the upper end of the extension member 5 is provided with an annular groove, so that a stepped surface is formed at the upper end of the extension member 5. The springs 10 are evenly arranged in a circle in six numbers, the bottom surface of the spring 10 is fixed on the bottom surface of the annular groove, the inner diameter of the annular plate 11 is equal to the inner diameter of the annular groove, the outer diameter of the annular plate 11 is equal to the outer diameter of the extension member 5, and the annular plate 11 is fixed at the top end of the spring 10. When there is no external force, the top surface of the annular plate 11 is flush with or slightly higher than the top surface of the extension member 5, so that the annular plate 11 covers the outside of the four second card slots around. When in use, manually pressing down the annular plate 11 can expose the second card slot, and at this time, the first engaging member 6 can be taken and placed.

[0074] In some technical solutions, a structure same as the foregoing annular groove, spring 10 and annular plate 11 is also provided between the cutter head 7 and the extension member 5 to stabilize the position of the second engaging member 9.

[0075] In this embodiment, the rotatable member 4, the extension member 5, and the cutter head 7 are all provided as hollow pipe fittings;

[0076] And / or, one end of the cutter head 7 away from the extension member 5 is provided with a blade portion 701.

[0077] In this technical solution, the blade part 701 is a fan-shaped sheet structure fixed at the hollow part on the lower side of the cutter head 7. The blade part 701 is evenly arranged in a circle with four pieces. The blade part 701 is used to break the rock and soil encountered during the rotation and descent of the cutter head 7, facilitating the movement of the rock and soil into the cutter head 7. At the same time, the rock and soil sample can also be stored through the hollow part in the extension part 5. During actual use, the rock and soil in the extension part 5 can be directly used as a sample for analysis.

[0078] In some technical solutions, the rotating part 4, the extension part 5, and the cutter head 7 are all arranged as hollow pipe fittings, and the blade part 701 is not provided at the lower side end of the cutter head 7.

[0079] In this embodiment, the side wall of the extension part 5 is provided with through holes.

[0080] In this technical solution, through holes are provided on the front, back, left, and right side walls of the extension part 5, facilitating the direct acquisition of the sample inside the extension part 5. This also facilitates the setting of the length of the extension part 5 and reduces the difficulty of obtaining the soil sample inside the extension part 5.
