Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering construction technology, specifically to a device for controlling the loose-lay thickness of soil filling in water conservancy projects. Background Technology

[0002] In the process of raising and reinforcing existing dikes in water conservancy projects, a large amount of soil is needed for filling and compaction to form new dikes. During construction, the loose thickness and compaction degree of the soil are key factors affecting the quality of the dike. Traditional methods for measuring loose thickness include the wire method, non-destructive testing, and the steel rod insertion method. The wire method involves setting up poles and then pulling a steel wire according to the design elevation for spreading. However, due to differences in the height of manually set poles, the sag of the steel wire under its own weight, and construction disturbance, the loose thickness can have a large error. Non-destructive testing uses ground-penetrating radar, ultrasonic testing, and other detection methods to detect the thickness of roadbed fill. However, this method is generally vehicle-mounted and not suitable for detecting the loose thickness of roadbed fill. The steel rod insertion method involves inserting a steel rod into the loose fill and directly measuring the loose thickness with a ruler.

[0003] Utility model patent CN218175794U discloses a portable, assembled iron slag roadbed filling loose thickness measuring device, including a base steel plate, a steel pipe vertically arranged above the base steel plate, a steel protective sleeve covering the steel pipe, the bottom of the steel protective sleeve fixed to the base steel plate, a handle at the top of the steel pipe, a conical tip at the bottom of the steel pipe, a graduated scale on the steel pipe, a through hole in the base steel plate through which the steel pipe can pass, a universal level on the base steel plate, and steel nails at the bottom of the base steel plate. After the roadbed filling material is laid in a layered and segmented sequence, after the set measuring points are initially leveled, the assembled measuring device is moved to the set measuring points, and the steel nails 2 at the bottom of the base 1 are pressed in. The universal level 13 is leveled so that the inserted steel pipe 8 is perpendicular to the filling ground. The limiting bolt 16 is loosened, and then the steel pipe 8 is inserted downwards through the handle 10 until it encounters the hard shell layer of the base. According to the relative change at the starting position of the upper scale 15, i.e. the upper annular guide steel pipe 7, the measured value is read as the loose thickness measurement data of the measuring point. After completion, the same method is used to move to the next measuring point for measurement. In this patent, the loose thickness of the soil at the measuring point can be known. During the measurement process, multiple points are selected for measurement to obtain the overall loose thickness of the soil. However, the thickness of the entire layer of filling soil is difficult to control, and the thickness can only be measured after the soil is loosened. It is difficult to use it to control the loose thickness of the soil during the filling process. Utility Model Content

[0024] In one embodiment, see Figure 1 , 2 This utility model relates to a device for controlling the loose thickness of soil filling in water conservancy projects, comprising a support component, a leveling component, a height adjustment component, and a measuring component.

[0034] Further, see Figure 3 The connecting sleeve 5 has a connecting cavity 23, and the connecting head 2 is spherical and located in the connecting cavity 23. The connecting sleeve 5 and the connecting head 2 are in clearance fit. The locking member 8 includes a locking stud that is threaded onto the connecting sleeve 5.

[0035] Preferably, the connecting cavity 23 is spherical, and the diameter of the opening end of the connecting sleeve 5 is smaller than the diameter of the connector 2, so that the connector 2 can rotate within the connecting cavity 23 without disengaging.

[0038] Preferably, the leveling rod 7 is a screw rod, and the leveling plate 6 is provided with four sets of leveling screw holes 25. The leveling rod 7 is installed in the leveling screw holes 25 by means of threads.

[0039] In the above setup, the leveling rod 7 is rotated to abut against the upper end face of the support base 1, thereby adjusting the level of the adjusting plate 6. The position of the adjusting plate 6 can be controlled by the level bubble 9. The four sets of leveling rods 7 can adjust the height of the four corners of the adjusting plate 6. During the adjustment process, the adjusting plate 6 swings along the connector 2.

Then, the four sets of leveling rods 7 are rotated to abut against the top of the support base 1, thereby fixing the position of the adjusting plate 6.

[0040] Further, see Figure 1 , 4 The center of the adjusting plate 6 is provided with a rotating sleeve 26, and one end of the adjusting rod 10 is rotatably connected to the rotating sleeve 26; the adjusting component 11 includes an adjusting sleeve 1101 connected to the adjusting rod 10 by a thread, the adjusting sleeve 1101 is provided with a connecting plate 27, the connecting plate 27 is provided with a support plate 29, the connecting plate 27 is provided with a sliding hole 28, the support plate 29 is located on the outer edge of the side wall of the support base 1, and the laser level 13 is installed on the support plate 29; one end of the limiting rod 12 passes through the sliding hole 28, and the limiting rod 12 is provided with a scale 30.

[0041] Preferably, the rotating sleeve 26 has a rotating cavity 31 inside. The rotating sleeve 26 is a hollow cylinder with one end open.

[0043] In the above setup, by rotating the height adjustment rod 10, the adjusting sleeve 1101 moves up or down under the action of the thread, thereby driving the laser level 13 to move up or down. The limiting rod 12 restricts the rotation of the adjusting sleeve 1101, so that the adjusting sleeve 1101 can only move up or down along the height adjustment rod 10. Since the connecting plate 27 is "L" shaped, the support plate 29 is located on the side of the support base 1. During the downward movement of the adjusting sleeve 1101, the support plate 29 moves down and can contact the ground.

[0044] In this embodiment, the support base 1 provides support for the entire pile.

When controlling the loose layer thickness of the soil, the height adjustment rod 10 is rotated to drive the adjustment sleeve 1101 and the support plate 29 to move upward according to the design requirements of the loose layer thickness of the soil. According to the scale 30, the distance between the laser line emitted by the laser level 13 and the ground is the thickness of the loose layer of soil, thereby controlling the loose layer thickness of the soil.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
