Description

Technical Field

[0001] The present invention relates to the technical field of geological disaster management, and in particular to an anchor hole measuring device for geological disaster management which is convenient for measurement and a measuring method thereof. Background Art

[0002] Geological disaster prevention and control refers to the assessment of adverse geological phenomena and the use of effective geological engineering techniques to change the process of these geological disasters in order to prevent or reduce the occurrence of disasters. The work of geological disaster prevention and control is based on the principle of prevention first, combining avoidance with control, and is carried out in accordance with the principles of prevention first, prevention and control combined, comprehensive planning, and comprehensive control.

[0003] Anchor holes are used for foundation pit excavation and anchoring of piles, walls, towers, etc. to increase their stability. Among the existing geological disaster control technologies, there is a method of using drilling grouting to pour concrete, but because the soil is soft and the foundation bearing capacity coefficient is small, it is easy to become unstable in rainstorms. The soil has a lot of moisture, which makes the soil deform and loose, thus deteriorating the protection effect. There is also a technology that uses anchor rods to drive into the slope to reinforce the soil. This type of technology is difficult to improve the problem of soil erosion on the surface of the slope soil layer. In the process of driving the anchor rods, it is necessary to dig anchor holes for driving the anchor rods; In the anchor hole measurement process, it is necessary to use a measuring piece to measure the anchor hole, such as the utility model with announcement number CN209512744U, which discloses a high slope anchor hole depth measuring ruler, which is spliced ​​by several sections of cylindrical rods of equal length. Two adjacent sections of cylindrical rods are connected by threads. The entire measuring ruler is covered with scales and takes the head end of the first section of the cylindrical rod as the starting point. The minimum division of the scale is 1 cm. The cylindrical rods are provided with numbers indicating the splicing order. Usually, the cylindrical rods are stacked together separately to save space and are convenient for storage. When measuring, the cylindrical rods are carried together to the measuring position for convenient transportation, and then spliced ​​according to the numbers and placed in the anchor hole. The hole depth can be known by reading the scale flush with the hole mouth. The measurement accuracy is high. Since it is spliced ​​in multiple sections, it can adapt to the measurement of holes of different depths.

[0004] However, when measuring the depth of the anchor hole, the measuring ruler in the above application has a limited length of the ruler body. Therefore, when measuring anchor holes of different depths, the measuring depth of the measuring ruler is limited. At the same time, the dim light in the anchor hole will also affect the measurement accuracy. Therefore, a convenient anchor hole measurement device for geological disaster management and a measurement method thereof are proposed to solve the above problems. Summary of the invention

9. The anchor hole measuring device for disaster management that is convenient for measurement according to claim 8 is characterized in that: The outer surface of the sleeve (61) is provided with an external thread matched with the threaded ring (62); the sleeve rod (65) is provided with a rectangular hole for the connecting rod (67) to pass through; the outer surfaces of the sleeve rod (65) and the second indicating rod (66) are both provided with a second scale mark (68); the outer side of the threaded ring (62) is provided with an annular groove located outside the limit block (64); the limit block (64) is L-shaped.

10. A convenient anchor hole measurement method for geological disaster control, characterized in that: The following steps are involved: S1. Support adjustment: Since the rotating adjustment screw (46) can push or pull the support rod (42) to rotate and adjust on the hinge block (41) through the adjustment rod (45) and the connecting rod (47), one side of the installation frame (1) can be supported and the height of one side of the installation frame (1) can be adjusted. By observing the bubble level (44) on the front of the installation frame (1), the height of both sides of the installation frame (1) can be adjusted to adjust the horizontality of the installation frame (1); S2, diameter measurement: after the mounting frame (1) is adjusted to be level, so that the height of the support block (43) is lower than the height of the sleeve (61), the lower part of the sleeve (61), together with the sleeve rod (65) and the second indicator rod (66) can be extended into the anchor hole, and then the movable ring (63) is driven to move downward by rotating the threaded ring (62). During the downward movement, the second indicator rod (66) is pushed out of the sleeve rod (65) by the connecting rod (67) until the second indicator rod (66) contacts the inner wall of the anchor hole. Then, the anchor hole diameter measurement can be completed by observing the second scale mark (68); S3, depth measurement: according to the excavation depth of the anchor hole, after assembling a measuring rod (31) larger than the depth of the anchor hole, the measuring rod can be passed through the support plate (2), and then the worm (52) is rotated to drive the gear (55) to rotate, thereby driving the measuring rod (31) to move downward into the anchor hole until it contacts the bottom of the anchor hole, and the depth of the anchor hole can be measured; S4, angle measurement: during the downward movement of the measuring rod (31), the measuring rod (31) is brought into contact with the side wall of the anchor hole. During the downward movement of the measuring rod (31), if the verticality of the anchor hole deviates, the downward moving measuring rod (31) will drive the support plate (2) to rotate and deviate on the mounting frame (1). After the bottom of the measuring rod (31) contacts the anchor hole, the fixing screw (37) can be rotated to lock the support plate (2). The deviation angle of the measuring rod (31) can be observed through the first indicating rod (33) and the digital angle ruler (34), thereby facilitating the operator to more conveniently measure the angle of the anchor hole.
