Description

Technical Field

[0001] The utility model relates to the field of foundation surface deformation monitoring, in particular to an observation pier device taking into account both manual observation and GNSS observation. Background Art

[0002] GNSS (Global Navigation Satellite System) measurement and manual observation are traditional monitoring methods for foundation surface deformation. GNSS measurement is an automated measurement. It works by installing buried measuring piers at the measured points. GNSS antennas are set on the measuring piers. The GNSS antennas receive satellite signals to locate the coordinates of the GNSS antennas, thereby measuring the deformation and displacement of the surface of the measuring point. 24-hour uninterrupted automatic measurement can be achieved.

[0003] Manual observation refers to setting up deformation observation piers at the measuring point location, and manually measuring the relative displacement value of the measuring point to obtain the surface deformation displacement at the measuring point. Usually, GNSS measuring points and manual measuring points need to be arranged at the same time, and the measurement results of each other are compared with each other. However, in the prior art, the two measuring points are arranged independently of each other. On the one hand, this will increase the use of measuring piers, and at the same time, there are requirements for the distance between the two measuring points. If the distance between the two measuring points is far, there is no basis for comparing the measurement results. If the distance between the two measuring points is close, the two measurements are easy to interfere with each other.

[0004] In this regard, Chinese patent CN219977319U discloses "an observation pier", which includes a vertically arranged pier body, a forced centering plate matching the GNSS mounting bracket is installed on the top of the pier body, an artificial observation device is installed at the bottom of the GNSS mounting bracket, and the artificial observation device can be a total station, a prism, etc., and a GNSS antenna is installed on the top of the GNSS mounting bracket, so that the purpose of integrating the two measuring points of artificial and GNSS is achieved, which can facilitate data comparison and save the number of pier bodies. However, the existing observation piers still have the following problems: first, the GNSS antenna and the GNSS mounting bracket have a certain weight, which has certain requirements on the installation strength of the GNSS mounting bracket; second, the GNSS antenna is an electrical device, and it is not very convenient to supply power to the GNSS antenna in remote areas; and technically, the existing observation piers lack lightning protection and grounding measures, and the related equipment is easily damaged by lightning strikes. Utility Model Content

[0005] The utility model aims to provide an observation pier device which can improve the installation strength of a GNSS installation bracket and takes into account both manual observation and GNSS observation.

[0006] In order to solve the above technical problems, the technical solution of an observation pier device taking into account both manual observation and GNSS observation in the utility model is as follows:

[0007] An observation pier device that takes into account both manual observation and GNSS observation, comprising a GNSS antenna, a GNSS mounting bracket, a manual observation device, a forced centering base and an observation pier, wherein the observation pier comprises a pier foundation and a vertical support arranged at the upper end of the pier foundation, the vertical support comprises a support shell and a shell concrete located inside the support shell and cast into an integral structure with the pier foundation, an annular mounting base plate is arranged at the upper end of the shell concrete, a base plate prefabricated steel bar cast into an integral structure with the shell concrete is fixed to the lower side of the mounting base plate, a blind hole nut is fixed to the lower side of the mounting base plate, and a base plate through-hole corresponding to each blind hole nut is provided on the mounting base plate, the GNSS mounting bracket comprises an upper mounting plate, a lower mounting plate and a plurality of connecting rods arranged at intervals along the circumferential direction and connected between the upper mounting plate and the lower mounting plate, the lower mounting plate is fixed to the mounting base plate by bracket bolts inserted into the blind hole nuts, the GNSS antenna is fixed to the upper mounting plate, the forced centering base plate is located in the inner hole of the mounting base plate, and the forced centering base plate is fixed to the top of the shell concrete.

[0008] Furthermore, the artificial observation device is composed of a prism installed on the upper end of the forced centering base.

[0009] Furthermore, an escape space for circumferentially avoiding the observation angle of the prism is formed between two circumferentially adjacent connecting rods.

[0010] Furthermore, the upper mounting plate is a strip structure extending in the left-right direction. A lightning rod and a Beidou communication module are also installed on the upper mounting plate. The GNSS antenna is installed in the middle of the upper mounting plate, and the lightning rod and the Beidou communication module are located on the left and right sides of the upper mounting plate.

[0011] Furthermore, a threading tube arranged in the up-down direction is preset in the shell concrete pier foundation, and the grounding wire connected to the lightning rod is installed in the threading tube.

[0012] Furthermore, the vertical support is a structure that is small at the top and large at the bottom. The side of the support shell of the vertical support is inclined with respect to the horizontal direction. Mounting bolts are pre-embedded in the shell concrete. One end of the mounting bolts passes through the side of the support shell and is used to connect a solar mounting bracket. A solar panel for supplying power to the GNSS antenna is installed on the solar mounting bracket. The mounting bolts are connected to rivet nuts located on the inner side of the support shell.

[0013] The beneficial effects of the utility model are as follows: in the utility model, a GNSS antenna and a manual observation device are integrated on the observation pier, so that GNSS observation and manual observation can be carried out simultaneously. In addition, the manual observation device for realizing manual observation is installed on the top of the vertical support through a forced centering base, and no force is generated on the GNSS mounting bracket. The upper mounting plate of the GNSS mounting bracket is used for the installation of the GNSS antenna, and the lower mounting plate is fixed to the mounting base plate by bracket bolts. The mounting base plate is reliably connected to the shell concrete by precast bolts of the base plate, thereby ensuring the reliable force of the GNSS mounting bracket. The use of blind hole nuts can avoid concrete entering the blind hole nuts from bottom to top and blocking the blind hole nuts when the shell concrete is poured. The gap between adjacent connecting rods can facilitate the observation of the manual observation equipment without obstructing the manual observation equipment. BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0025] The implementation example of an observation pier device that takes into account both manual observation and GNSS observation in the utility model is as follows: Figures 1 to 7 As shown:

[0026] It includes an observation pier, a forced centering base 8, manual observation equipment, a GNSS mounting bracket 4 and a GNSS antenna 2, etc. The observation pier includes a pier foundation 10 and a vertical support 6 arranged at the upper end of the pier foundation 10. The pier foundation 10 is a concrete structure. The vertical support includes a support shell 18 and a shell concrete 19 located on the inner side of the support shell and cast into an integral structure with the pier foundation. The support shell 18 is a conical structure that is small at the top and large at the bottom.

[0027] The upper end of the shell concrete is provided with an annular mounting base plate 14, and four base plate precast steel bars 16 arranged at intervals along the circumferential direction are fixed to the lower side of the mounting base plate 14. The shell concrete 19 and the base plate precast steel bars 16 are cast into an integral structure. The mounting base plate is provided with a plurality of base plate through holes 21 arranged at intervals along the circumferential direction. The lower side of the mounting base plate 14 is fixed with blind hole nuts 15 arranged corresponding to the basic through holes. The blind hole nuts 15 refer to nuts blocked at the bottom. The threaded holes of each blind hole nut are respectively located directly below the corresponding base plate through holes 21. The GNSS mounting bracket includes an upper mounting plate 13, a lower mounting plate, and a plurality of connecting rods 12 arranged at intervals along the circumferential direction connected between the upper mounting plate and the lower mounting plate. In this embodiment, there are three connecting rods. The lower mounting plate is an annular structure, and the lower mounting plate is fixed to the mounting base plate 14 by bracket bolts inserted into the blind hole nuts. The gap between two adjacent connecting rods 12 in the circumferential direction forms an avoidance space for avoiding the observation angle of the prism.

[0028] The upper mounting plate 13 is a strip structure extending in the left-right direction. The upper end of each connecting rod 12 is fixed to the bottom of the upper mounting plate. A lightning rod 1 and a Beidou communication module 3 are also installed on the upper mounting plate. The GNSS antenna 2 is installed in the middle of the upper mounting plate 13, and the lightning rod 1 and the Beidou communication module 3 are located on the left and right sides of the upper mounting plate.

[0029] The forced centering base is located in the inner hole of the mounting base plate, and the forced centering base is fixed to the top of the shell concrete.

[0030] The shell concrete pier foundation is preset with a threading tube 17 arranged in the up-down direction, and the grounding wire connected to the lightning rod is installed in the threading tube. This can avoid the problem of the grounding wire leaking out and causing unsightly and easy to be eaten by insects and rats.

[0031] Since the support shell is a conical shell with a small top and a large bottom, the side of the support shell is inclined to the horizontal direction, and the axis of the support shell extends in the up-down direction. A mounting bolt 22 is embedded in the shell concrete, and one end of the mounting bolt is passed through the side of the support shell and is used to connect the solar mounting bracket 11. The solar mounting bracket 11 is equipped with a solar panel 5 for supplying power to the GNSS antenna, and the mounting bolt 22 is connected to a rivet nut 23 located inside the support shell. The solar panel 5 supplies power to the Beidou communication module and the GNSS antenna.

[0032] The manual observation equipment in this embodiment is composed of a prism installed on the upper end of the forced centering base, the prism is between three connecting rods, and the height of the solar panel is lower than the height of the prism. The prism meets the technical requirements of manual observation, and deformation observation can be performed by manual observation to form data comparison and analysis with GNSS automatic observation.

[0033] The GNSS mounting bracket is installed on the mounting base plate, which ensures the installation strength of the GNSS mounting bracket, improves the stability of the equipment, and helps to ensure the accuracy of the monitoring data. The lightning rod and grounding settings enable the GNSS monitoring equipment to operate stably.
