Description

Technical Field

[0001] The invention belongs to the technical field of engineering measurement, and in particular relates to a measurement control pile. Background Art

[0002] With the increasing development of engineering construction, surveying plays an important and indispensable role in its development. Acquiring spatial data related to engineering construction is a key goal of the surveying process. Engineering surveying can provide reliable and accurate spatial data for design, construction, and operation, ensuring the normal operation of engineering projects and, in turn, the speed, quality, and effectiveness of engineering construction.

[0003] Chinese patent application No. 2022211067772 discloses a new type of measurement control pile, which relates to the technical field of engineering measurement equipment, including a No. 1 tube, a No. 2 tube is provided below the No. 1 tube, a connecting plate is provided between the No. 1 tube and the No. 2 tube, a connecting pile is provided at the lower end of the connecting plate and inside the No. 2 tube, a reinforcement ring is provided on the connecting pile, a mounting plate is provided at the upper end of the No. 1 tube, a mounting bolt is passed through the middle position of the mounting plate, and a fixing hole is passed through the upper end of the side wall of the No. 1 tube, so that the control pile body leaks out to the ground surface, and the total station and the measurement base can be directly set up on the mounting plate. During the measurement work, there is no need to set up a tripod to install the instrument, and the No. 1 tube and the No. 2 tube are connected together through the connecting plate, and the No. 2 tube is inserted into the concrete foundation. The No. 2 tube can be fixed by stepping on the connecting plate. It is more convenient to work, and the surveyor can easily find the control pile.

[0004] The above-mentioned patent discloses that the connection and fixing effect of the surveying instrument by setting a mounting bolt on the upper end of the mounting plate is poor. When the surveying instrument needs to be installed, the surveying instrument needs to be placed on the upper end of the mounting bolt, and then the mounting bolt is screwed into the lower end of the surveying instrument by using a wrench. Since the mounting plate is fixed to the No. 1 barrel, the wrench cannot screw the lower end of the mounting bolt. The wrench needs to screw the mounting bolt between the surveying instrument and the mounting plate, resulting in a gap between the surveying instrument and the mounting plate after subsequent installation. The fixing effect of the surveying instrument is poor, which is inconvenient for the measurement work of the surveying instrument. At the same time, the original device does not have the guiding function for the No. 2 barrel when installing it. The No. 2 barrel is prone to tilt when moving downward in the concrete foundation, and it cannot be guaranteed that the No. 2 barrel remains vertical. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention provides a clamping assembly. When measurement work is required, the surveying instrument is placed on the mounting plate. The double-axis screw is rotated by turning the handle. The rotation of the double-axis screw drives the two slides to approach each other in the rectangular groove at the upper end of the mounting plate. At the same time, the two slides drive the two clamps to approach each other. The two clamps approach each other to clamp and fix the surveying instrument on the mounting plate. At the same time, a rubber pad is provided at one end of the clamp to play an anti-slip role, thereby improving the clamping effect of the clamp and preventing the clamp from damaging the surface of the surveying instrument. By providing the clamping assembly, the surveying instrument can be conveniently fixed on the mounting plate, and the installation is more secure.

[0016] 2. The present invention sets a bottom ring, which is first placed in the position where the control pile needs to be erected, and the conical column at the upper end of the fixed rod protrudes from the ground. Then, a concrete foundation is poured into the position where the control pile needs to be erected. After the concrete foundation is poured, the No. 2 barrel is placed into the concrete foundation, and at the same time, the conical column at the upper end of the fixed rod passes through the fixing ring at the lower end of the No. 2 barrel through the insertion hole. Then, the staff steps on the connecting plate. Under the gravity of the No. 2 barrel and the staff, the connecting plate pushes the No. 2 barrel into the concrete foundation, and at the same time, the fixing ring slides on the fixing rod. By setting the fixing ring, the fixing rod and the bottom ring, the No. 2 barrel can be guided so that the No. 2 barrel can move vertically downward in the concrete foundation, thereby preventing the No. 2 barrel from tilting in the concrete foundation and improving the installation quality of the No. 2 barrel.

[0017] 3. The present invention sets an arc cover. When surveying and mapping operations are not required, the arc cover can be extracted by a handle, and several positioning columns at the lower end of the arc cover are inserted into the positioning holes at the upper end of the mounting plate to achieve the effect of limiting and fixing the arc cover. After the arc cover is installed on the mounting plate, it can protect components such as the splint at the upper end of the mounting plate. BRIEF DESCRIPTION OF THE DRAWINGS
