Embodiment 1

[0035] Such as Figure 1~4 As shown, a discrete cushion thickness detection device includes a measuring drill 1, a positioning ring 2 movably fitted on the measuring drill 1, and a handle 3 fixed on the upper end of the measuring drill 1. The measuring drill 1 is a cylindrical metal As for the rod, the bottom end of the measuring drill 1 is a cone head 4 and a threaded section 5 is arranged above the cone head 4, and the top of the measuring drill 1 is provided with a hammer head 14 with a radius larger than that of the measuring drill 1.

[0036] Specifically, the positioning ring 2 is a circular ring made of rubber material, the inner ring of the positioning ring 2 matches the cylindrical surface of the measuring drill 1 and fits through the elastic contact of rubber; the threaded section 5 is provided with equal pitch For the thread provided, the length of the thread segment 5 is not less than 100mm.

[0037] The handle 3 is arranged at 200 mm from the top of the measuring...

Embodiment 2

[0042] When the discrete cushion thickness detection device is used to detect the cushion thickness, the specific process is: according to the known cushion thickness standard, the measuring drill 1 is vertically driven into the cushion at the standard thickness of the cushion plus a length of 50mm, Make the threaded section 5 of the measuring drill 1 contact the soil base under the cushion, slide the positioning ring 2 along the measuring drill 1 to the top surface of the cushion, pull out the measuring drill 1 through the handle 3, and measure the threaded section 5. The distance between the fresh soil top layer and the positioning ring 2, this distance value is the cushion thickness.

[0043] If it is not found that no fresh soil is brought out of the threaded section 5 during the above-mentioned detection process, then enter the distance increase measurement, and if it is found that the thread section 5 is completely filled with fresh soil during the above-mentioned detecti...

Embodiment 3

[0049] Such as Figure 5-7 As shown, on the basis of a discrete cushion thickness detection device and detection method mentioned in Embodiment 1 and Embodiment 2, in the construction process, in the process of large-scale cushion detection, it is inevitable to encounter geological If the situation is complicated or manual control is inaccurate and the process state of the measuring drill 1 is not vertical, the depth of the measuring drill 1 will not be vertical, which will cause errors in the measured cushion thickness. If the thickness of the cushion layer is too thick, if the thickness of the cushion layer is not detected, it will affect the later construction and maintenance of the overall project. Therefore, an auxiliary base 8 is proposed to ensure that the measuring drill 1 is driven vertically.

[0050] The structure of the auxiliary base 8 is composed of two parallel substrates 9 up and down. The two substrates 9 are connected by brackets 10. The substrates 9 are prov...

Abstract

The invention provides a discrete cushion layer thickness detection device which comprises a measuring drill rod, a positioning ring movably sleeved on the measuring drill rod and a handle fixed at the upper end of the measuring drill rod, the measuring drill rod is a cylindrical metal rod piece, the bottom end of the measuring drill rod is a conical head, a threaded section is arranged above theconical head, and a hammer head with the radius larger than that of the measuring drill rod is arranged at the top end of the measuring drill rod. And a detection method which is easy to operate, lowin cost, small in damage to the integrity of the cushion layer and capable of effectively and accurately detecting the thickness of the cushion layer is provided on the basis of the discrete cushion layer thickness detection device. The problems that in the discrete cushion thickness detection process, the damage of a pit slot measurement method to a cushion is large, and an elevation measurementmethod cannot guarantee the correctness of an accurate measurement result are solved.

Description

technical field [0001] The invention relates to the field of discrete cushion thickness measurement for road, municipal and construction projects, in particular to a discrete cushion thickness detection device and detection method. Background technique [0002] During the construction of highways, municipal projects, construction projects, etc., it is necessary to lay discrete cushions above the soil base for the purposes of drainage, shock absorption, and antifreeze. The laying of discrete cushions will have a direct impact on the quality of the project. [0003] In the process of acceptance or testing of discrete cushion thickness, pit digging measurement method and height measurement method are generally used; [0004] The traditional pit digging measurement method needs to dig pits on the laid cushion, which is difficult, labor-intensive, time-consuming, low in accuracy, and destructive to the integrity of discrete cushions. The strength and stability of the groove are ...
