[0022] It is easy to understand that, according to the technical scheme of the present application, a person skilled in the art can propose a plurality of structure modes and implementation modes which can be replaced with each other without changing the essential spirit of the present application. Therefore, the following specific embodiments and the accompanying drawings are only exemplary descriptions of the technical scheme of the present application, and should not be regarded as the whole or as a limitation or restriction on the technical scheme of the present application.
[0023] A hard pavement static sounding opening device, comprising a positioning frame and an opening device used in cooperation with the positioning frame; as shown in Figure 1 The positioning frame comprises a sleeve 1 and a frame column 2, and the frame column 2 is a plurality of frame columns arranged around the sleeve 1. The frame column 2 can be arranged around the sleeve 1, and the number of frame columns 2 is four, which are sequentially arranged around the sleeve 1.
[0024] It should be understood that, as shown in Figure 1 The number of frame columns 2 is four in the present application, which is only for clear description of the embodiment of the present application, and is not a specific limitation on the number of frame columns 2. In the specific embodiment, the number of frame columns 2 can be three, five or more, which should be regarded as equivalent embodiments of the above-mentioned embodiments, and only ensures that the frame column 2 can be arranged around the sleeve 1.
[0025] The sleeve 1 is fixedly integrated with the plurality of frame columns 2 by a fixed frame. The number of fixed frames can be two groups, and the two groups of fixed frames are arranged at both ends of the sleeve 1 and fixedly integrate the sleeve 1 with the frame columns 2. It is worth noting that the number of fixed frames should be at least two groups. If the number of fixed frames is more than two groups, they should be arranged according to the principle of equal interval based on the length of the sleeve 1 to ensure the stability of the combination of the sleeve 1 and the frame columns 2. The opening device used in cooperation reciprocates along the length direction of the sleeve 1.
[0026] A base 4 is provided below the aforementioned frame column 2. The base 4 can be adjusted by a locking device to regulate the distance between the upper end of the base 4 and the lower end of the frame column 2, in order to meet the requirements of uneven sites, ensure a level working surface, and thus avoid tilting during the drilling process. The aforementioned locking device includes an adjusting rod 8 fixedly installed on the upper end of the base 4 and a locking element 5. The adjusting rod 8 can extend into the frame column 2 from the lower end of the frame column 2. A locking hole 3 is provided on at least one of the frame column 2 and the adjusting rod 8. The locking element 5 is embedded in the locking hole 3 to lock the distance between the lower end of the frame column 2 and the upper end of the base 4. The following is a detailed description of the arrangement of the adjusting rod 8, the locking element 5, and the frame column 2:
[0027] Example 1
[0028] like Figure 2 As shown, a number of locking holes 3 are evenly spaced along the length of the frame column 2 and the adjusting rod 8. The locking element 5 is not fixedly connected to the frame column 2 and the adjusting rod 8. It can be a pin. After the adjusting rod 8 is inserted into the frame column 2 and the locking holes 3 on the adjusting rod 8 and the frame column 2 are aligned, the locking element 5 passes through the locking hole 3 on the frame column 2 from the outer edge of the frame column 2 and then through the locking hole 3 on the adjusting rod 8, thereby locking the relative position of the frame column 2 and the adjusting rod 8, thus locking the distance between the lower end of the frame column 2 and the upper end of the base 4.
[0029] Example 2
[0030] like Figure 3 As shown, a number of locking holes 3 are equally spaced along the length of the adjusting rod 8. The locking element 5 is fixedly installed on the frame column 2. It can be a pin. Its holding section is located on the outside of the frame column 2, and the locking section is located inside the frame column 2. An elastic structure 9 is provided between the locking section and the inner wall of the frame column 2. The side of the elastic structure 9 facing the adjusting rod 8 is fixed on a baffle. The baffle is fixedly installed on the part of the locking element 5 that is inserted into the frame column 2. Under normal conditions, the elastic structure 9 is in an unloaded state. If the adjusting rod 8 is directly inserted into the frame column 2, it will be blocked by the locking section of the locking member 5 and cannot continue to extend into the frame column 2. It is necessary to pull the grip section to compress the elastic structure 9. At this time, the adjusting rod 8 can continue to extend into the frame column 2. During the process, the elastic structure 9 can be compressed by the action of the baffle and the inner wall of the frame column 2. After the end of the locking section and the locking hole 3 located above the adjusting rod 8 are aligned, the locking member 5 falls into the locking hole 3 due to the action of the elastic structure 9 after the grip section is released, thereby locking the relative position of the frame column 2 and the adjusting rod 8, thus locking the distance between the lower end of the frame column 2 and the upper end of the base 4.
[0031] Example 3
[0032] As Figure 4 shown, along the length of the frame column 2 equidistantly opened several locking holes 3, on the adjustment rod 8 is provided with a movable rod 10, on the movable rod 10 and the outer edge surface of the adjustment rod 8 is provided with a elastic structure 9, the elastic structure 9 is fixed on a baffle towards the frame column 2, the baffle is fixedly arranged on the part of the movable rod 10 into the frame column 2. In the normal state, the elastic structure 9 is in the state of no force, at this time the width of the adjustment rod 8 away from the locking hole 3 side to the end of the movable rod 10 is greater than the diameter of the frame column 2, so the elastic structure 9 needs to be compressed to put the adjustment rod 8 into the frame column 2. In the specific use, first of all, the adjustment rod 8 is put into the frame column 2 by compressing the elastic structure 9, the elastic structure 9 is compressed under the action of the baffle and the outer edge surface of the adjustment rod 8 in the process, the movable rod 10 is not towards the locking hole 3 in the process, after adjusting the distance between the lower end of the frame column 2 and the upper end of the base 4, the movable rod 10 is locked and fixed towards the locking hole 3.
[0033] The base 4 in the above-mentioned embodiments 1-3 can be provided with anti-skid lines on the side facing the ground to cope with uneven ground or wet and slippery ground, ensuring the stability of the drilling process.
[0034] The opening device applied in the utility model comprises a drill bit 7, a drill rod and a core tube 6, wherein the drill bit 7 is a diamond drill bit 7, as shown in the figure, which is fixed to one end of the core tube 6 in a threaded connection manner, one end of the drill rod is fixed to the other end of the core tube 6 in a threaded connection manner, and the other end of the drill rod is riveted to the hydraulic static sounding winch. Figure 5
[0035] By using the foregoing opening device in cooperation with the positioning frame, the distance between each base 4 and each frame column 2 can be adjusted according to the actual site topography during the construction process to ensure the horizontal working surface, avoid the inclination during the drilling process, stably break the hard material layer at a uniform speed, facilitate the later static sounding construction, and avoid the damage of the static sounding probe.
[0036] The technical scope of the utility model is not limited to the content in the foregoing description, and those skilled in the art can make various deformations and modifications to the foregoing embodiments without departing from the technical thought of the utility model, and these deformations and modifications shall all belong to the protection scope of the utility model.
