Description

Technical Field

[0001] This invention belongs to the field of slope control technology, and specifically relates to an efficient slope cutting construction method. Background Technology

[0002] Water conservancy projects often involve the excavation of artificial channels. These artificial channels employ concrete lining for slopes, which requires high precision in slope cutting. Improving the accuracy and efficiency of slope cutting is increasingly becoming a key factor affecting project progress and cost. Existing slope cutting methods are often rather crude, involving simple line marking followed by the gradual cutting of slopes using excavators and other equipment, which cannot guarantee accuracy and efficiency. Therefore, it is necessary to design an efficient slope cutting construction method to solve the above problems. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an efficient slope cutting construction method. This method solves the problems of low accuracy and poor efficiency of existing slope cutting methods and has the characteristic of achieving precise slope cutting.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an efficient slope cutting construction method, comprising the following steps: An efficient slope cutting construction method includes the following steps: S1, the slope is roughly cut using an excavator, with a protective layer reserved; S2, drive four wooden stakes vertically at the four corners of the rough slope area, and use a plumb line to control the wooden stakes to ensure verticality; S3. Use a total station or RTK measuring instrument to measure the coordinates of the top of the wooden pile, calculate the difference in elevation between the top of the wooden pile and the design slope, and mark a line on the wooden pile at the same distance from the design slope. S4. Tie a thin rope to the two upper and two lower wooden stakes at the marked lines, and tie a movable hook rope between the upper and lower fixed thin ropes; or tie a fixed thin rope to the two left and right wooden stakes respectively, and tie a movable hook rope between the left and right fixed ropes. S5, the handle of the shovel used by the operator is marked with a line, and the distance between the line and the bottom of the shovel and the distance between the line and the wooden stake is the same as the distance from the designed slope; a circular spirit level is installed on the shovel, and a steel plate is welded to the bucket teeth of the excavator, and the operator works with the excavator to precisely cut the slope. S6 involves rough cutting a large area of ​​the slope in one go using the method in step S1, and then repeating the operation from step S2 to S5. In step S2, only two wooden stakes need to be removed before proceeding to the next section, thus controlling the precise cutting of the entire slope.

[0005] Preferably, in steps S1 to S5, the plane formed by four points at the same distance from the designed slope is parallel to the designed slope, and the distances from the plane to the line connecting any two of the four points and the line connecting any point on the two connecting lines are always equal, equal to the distance from the four points to the plane.

[0006] Preferably, in steps S4 and S5, the elevation difference measurement is performed using a movable hook hanging method and a shovel marking method.

[0007] Furthermore, the rope should be lightweight, resilient, and smooth to prevent sagging and facilitate hook sliding; nylon rope is preferable. The hook should be made of thick iron wire, lightweight yet with a certain degree of rigidity. The distance between the shovel handle marking and the bottom should be the same as the distance between the wooden stake marking and the designed slope marking. The height of the marking can be adjusted appropriately according to the amount of remaining soil on the slope. A vertical distance should be used. When driving the wooden stake, a plumb line should be used to control the verticality. The shovel should be used to measure the level bubble in the center.

[0008] Furthermore, steel plates are welded to the excavator bucket teeth to facilitate the cutting of a flat surface, and any uneven areas are leveled manually.

[0009] The beneficial effects of this invention are as follows: In this invention, four wooden stakes are randomly driven into the rough slope surface with a protective layer. A uniform distance line from the designed slope surface is marked on the wooden stakes. Thin ropes are tied to the marked lines on the upper two stakes and the lower two stakes. A movable hook rope is tied between the upper and lower fixed ropes. The handle of the shovel used by the operator is marked with a line, and steel plates are welded to the bucket teeth of the excavator. The operator works with the excavator to precisely cut the slope surface. This reduces the reliance on slope cutting measuring instruments, reduces labor costs, increases slope cutting efficiency, and avoids the inefficient situation of "digging one shovel and measuring one time".
