Description
TECHNICAL FIELD
[0001] The application relates to the technical field of road construction monitoring, and particularly discloses a settlement observation device for highway high slope construction. BACKGROUND
[0002] In order to monitor the settlement deformation of a high slope during a construction period and an operation period in real time and prevent geological disasters such as landslides, it is a conventional monitoring method to arrange settlement observation plates in a gradient direction of the slope in stages.
[0003] At present, a typical installation process of the settlement observation plate in the industry is as follows: firstly, a foundation pit is excavated to a stable soil layer or a bedrock required by design at a predetermined position of the slope; secondly, a prefabricated bottom plate of the settlement observation plate and a support connected with the bottom plate are hoisted and placed stably at the bottom of the foundation pit; thirdly, concrete is poured in the foundation pit to fix the bottom plate and the support; and finally, a special measuring mark located at the top of the support is installed on the solidified concrete base, so as to form a complete observation point.
[0004] However, due to the influence of factors such as complex geological conditions of a field construction site, limitation of excavating tools and rainwater scouring, it is difficult to ensure that the bottom of the foundation pit is an ideal plane with absolute level, and the surface of the bottom of the foundation pit often has inclination, unevenness or soft soil layer. When the concrete is poured, the concrete slurry with high fluidity is extremely easy to seep and accumulate under the prefabricated bottom plate along the gap between the uneven inner wall of the foundation pit and the edge of the bottom plate. The bottom plate is displaced or inclined before and after the initial setting of the concrete, so that the finally fixed bottom plate plane deviates from the design required level or predetermined gradient plane. Since the measuring mark of the settlement observation plate is connected with the bottom plate through the rigid support, the inclination of the bottom plate will be directly transmitted to the measuring mark at the top, so that the spatial coordinates and attitude of the measuring mark deviate from the design value. The deviation of the measuring mark causes systematic errors in the observation data on the reference, so that the settlement deformation of the slope cannot be truly reflected, and the monitoring and early warning are meaningless.
[0005] In order to correct the problem, the construction personnel have to carry out time-consuming and labor-consuming secondary processing, including releveling, even chiseling the poured concrete and taking out and reinstalling the whole observation plate. Such rework not only makes the construction process complicated, but also consumes additional labor, material and time costs, and seriously interferes with the continuous operation of the main procedures such as slope excavation and support, directly affecting the overall construction progress and control nodes. At the same time, repeated excavation and disturbance on the high slope also brings certain safety risks. In view of this, the utility model provides a settlement observation device for highway high slope construction, so as to solve the above problems. CONTENT OF THE UTILITY MODEL
[0006] The utility model aims at solving the problem that the position of the column is easy to deviate in the installation process of the traditional settlement observation plate, and the secondary calibration affects the overall construction progress.
[0007] To achieve the above object, the utility model discloses a basic scheme provides a settlement observation device for highway height side slope construction, comprising:
[0008] The bottom plate is adapted to the inner bottom surface of the foundation pit.
[0009] The stand is arranged at the center of the bottom plate and extends out of the foundation pit at the top.
[0010] The reinforcing member is threadedly connected with the stand and has a drill bit at one end that can pass through the bottom plate and drill into the bottom surface of the foundation pit.
[0011] The observation plate is arranged at the top of the stand.
[0012] Further, the bottom of the stand is provided with a cavity to accommodate the debris discharged when the drill bit drills into the foundation pit.
[0013] Further, the stand is hollow inside, and the inner wall of the stand is provided with an internal thread sleeve, and the reinforcing member cooperates with the internal thread sleeve.
[0014] Further, there is a gap between the bottom of the internal thread sleeve and the bottom of the stand, and the length of the gap is adapted to the length of the drill bit.
[0015] Further, the top of the stand is provided with a fixing column for fixing the observation plate.
[0016] Further, the fixing column includes a stud threadedly connected with the top of the stand and a nut arranged at the top of the stud.
[0017] Further, the inner diameter of the stud is greater than the inner diameter of the internal thread sleeve.
[0018] Further, the bottom of the observation plate is provided with a protective ring that is sleeved on the outer wall of the top of the stand.
[0019] Further, it further includes a baffle arranged at the edge of the four sides of the bottom plate.
[0020] Further, flow guide grooves are arranged on both sides of the baffle, and the bottom of the flow guide groove is inclined towards the center of the bottom plate.
[0021] The principle and effect of the present scheme are as follows:
[0022] 1. The utility model sets a reinforcing member in the stand, after the bottom plate is installed into the foundation pit, the drill bit on the reinforcing member drills into the bottom surface of the foundation pit, thereby the stand, the bottom plate and the observation plate are secondarily reinforced as a whole, to prevent the position of the bottom plate and the stand from being inclined during the concrete pouring process, thereby effectively solving the problem that the position of the stand is easy to deviate during the installation process of the traditional settlement observation plate, and the overall construction progress is affected by the need for secondary calibration.
[0023] 2. By setting up a cavity, this utility model effectively prevents debris generated during the secondary reinforcement of the column from squeezing the column and causing the column position to shift, thereby further improving the accuracy requirements for the installation of the column and observation plate.
[0024] 3. This utility model uses a protective ring to protect the bottom of the column, which effectively reduces corrosion at the joint between the top of the column and the observation plate, thereby further improving the accuracy of the observation plate during use and enhancing the long-term reliability of the data.
[0025] 4. By setting baffles and guide channels, this utility model guides the concrete flowing to the inner wall of the foundation pit back to the surface of the bottom plate, further preventing the concrete from causing the bottom plate and columns to shift. Attached Figure Description

[0029] Figure 3 A cross-sectional view of a settlement monitoring device for highway elevation slope construction, as proposed in an embodiment of this application, is shown.
[0030] The reference numerals in the accompanying drawings include: base plate 1, column 2, observation plate 3, nut 4, protective ring 5, baffle 6, reinforcement 7, drill bit 8, stud 9, and internal threaded sleeve 10. Detailed Implementation
[0031] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0032] A settlement monitoring device for highway elevation slope construction, implementing, for example... Figure 1 As shown: It includes a base plate 1, columns 2, observation plates 3, and fixed columns, etc.
[0033] The base plate 1 is installed on the inner bottom surface of the foundation pit. The bottom of the column 2 is fixed by welding at the center of the column 2, and the height of the column 2 is higher than the depth of the foundation pit, so that the top of the column 2 extends out of the foundation pit. The observation plate 3 is installed on the top of the column 2, so that the observation plate 3 is stably installed on the outside of the foundation pit for subsequent observation and measurement.
[0034] like Figure 2 As shown, column 2 is a hollow structure with its top and bottom completely penetrating. The top of column 2 is threaded with a fixed column. The fixed column includes a stud 9 that is threaded to the internal thread at the top of column 2 and a nut 4 on the top of stud 9. The observation plate 3 is fixed to the top of column 2 by stud 9 and nut 4 to facilitate subsequent observation and measurement.
[0035] Inside the column 2, a reinforcement member 7 is installed via an internal threaded sleeve 10 and a threaded connection. The bottom of the reinforcement member 7 extends out of the internal threaded sleeve 10 and is equipped with a drill bit 8. The top of the reinforcement member 7 is provided with an internal hexagonal hole so that external equipment such as a long-handled external hexagonal wrench can be inserted into the column 2 and rotated so that the drill bit 8 can drill into the stable soil layer at the bottom of the foundation pit.
[0036] After the base plate 1 is installed into the foundation pit, the drill bit 8 on the reinforcement part 7 is used to drill into the bottom of the foundation pit, thereby reinforcing the column 2, base plate 1 and observation plate 3 as a whole for a second time. This prevents the base plate 1 and column 2 from tilting during the concrete pouring process, thus effectively solving the problem that the position of column 2 is easily offset during the traditional installation of settlement observation plate 3, which requires secondary calibration and affects the overall construction progress.
[0037] In one possible embodiment, there is a gap between the bottom of the internal threaded sleeve 10 and the bottom of the column 2, and the gap is adapted to the length of the drill bit 8, so that a cavity is formed between the bottom of the internal threaded sleeve 10 and the bottom of the column 2 to accommodate the debris discharged when the drill bit 8 drills into the foundation pit. This prevents the debris generated during the secondary reinforcement of the column 2 by the reinforcement component 7 from squeezing the column 2 and causing the column 2 to shift in position, thereby further improving the installation accuracy of the column 2 and the observation plate 3.
[0038] In one possible embodiment, the bottom of the observation plate 3 is provided with a protective ring 5 that is fitted onto the outer wall of the top of the column 2. The protective ring 5 is made of elastic rubber, which protects the bottom of the column 2, effectively reduces corrosion at the joint between the top of the column 2 and the observation plate 3, thereby further improving the accuracy requirements of the observation plate 3 during use and enhancing the long-term reliability of the data.
[0039] In one possible embodiment, baffles 6 are provided along the four edges of the base plate 1, and guide channels are provided through the left and right sides of the baffles 6. The bottom of the guide channels is inclined towards the center of the base plate 1, so that during the concrete pouring process, the concrete flowing to the inner wall of the pit is guided back to the surface of the base plate 1, further preventing the concrete from causing the position of the base plate 1 and the column 2 to shift.
[0040] Compared with existing technologies, this settlement monitoring device has advantages such as a high success rate of installation on the first attempt, accurate monitoring data benchmarks, improved construction efficiency, guaranteed construction period, enhanced long-term stability, high structural integration, and good construction adaptability.
[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
