Description

Technical Field

[0001] This invention relates to the field of embankment engineering technology, and in particular to a distance-measuring wheel-type device for measuring the internal deformation of soil in concealed embankment projects. Background Technology

[0002] The soil internal deformation measurement device for embankment projects is a specialized device used to monitor the deformation behavior of soil, such as settlement, bulging, or horizontal displacement, in embankment projects (e.g., roadbeds, embankments, and foundation pit backfilling). Its core function is to capture soil deformation data and convert it into quantifiable indicators (e.g., settlement and displacement), providing a basis for project safety assessment, design optimization, and construction adjustments. Measuring soil internal deformation is a crucial link in the quality control and safety management of embankment projects. Soil settlement or bulging in embankment projects (e.g., roadbeds and embankments) can lead to structural cracking, landslides, or even collapse. For example, uneven settlement of the roadbed can cause pavement cracking, affecting traffic safety; embankment settlement can lead to the formation of seepage channels, causing dam failure accidents.

[0003] Traditional solutions for measuring internal settlement deformation of soil use single-point or multi-point settlement gauges or settlement plates. The measuring rods of traditional settlement plates or settlement gauges are relatively rigid rods, which are prone to mutual interference during construction and are also easily damaged and fail. Therefore, a distance-measuring wheel-type device for measuring the internal deformation of soil in concealed filling projects is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the measuring rods of traditional settlement plates or settlement gauges are relatively rigid members, which are prone to mutual interference during construction and damage and failure. Therefore, this invention proposes a distance-measuring wheel-type device for measuring the internal deformation of soil in concealed filling projects.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A measuring wheel-type soil internal deformation measuring device for concealed embankment projects includes a mounting plate. A support rod is mounted on the upper part of the mounting plate. A measuring wheel shaft is rotatably connected to the side of the support rod. A measuring wheel is mounted on the outer side of the measuring wheel shaft. A steel wire is movably connected to the side of the measuring wheel. A settlement plate is mounted on the end of the steel wire away from the measuring wheel. Predetermined tension ropes are symmetrically mounted on the upper part of the mounting plate. The ends of the two predetermined tension ropes away from the mounting plate are fixedly connected to the measuring wheel shaft.

[0006] The above technical solution further includes: a steel wire outer sleeve is installed on the outside of the steel wire.

[0007] A rotating rod is rotatably connected to the side of the measuring wheel. The rotating rod is located in a non-central position of the measuring wheel, and the steel wire is installed on the side of the rotating rod.

[0008] The upper part of the mounting plate is equipped with a data recording and storage chip for measuring wheel test settlement plate, which is used to store the settlement data measured by the measuring wheel.

[0009] The steel wire is made of indium steel and is used to transmit the internal deformation of the soil to the measuring wheel.

[0010] The predetermined tension rope applies a predetermined tension to the measuring wheel shaft to maintain the tension between the measuring wheel and the steel wire.

[0011] The rotating rod can rotate around its connection point with the measuring wheel, and is used to convert the linear displacement of the steel wire into the rotational motion of the measuring wheel.

[0012] The settlement plate is embedded inside the fill soil and is used to move the steel wire as the soil deforms.

[0013] The present invention has the following beneficial effects: In this invention, a flexible connection between a steel wire and a measuring wheel replaces the traditional rigid measuring rod, solving the problem that rigid measuring rods are easily affected by construction interference and are prone to damage and failure during the installation process. At the same time, it reduces the measurement error caused by insufficient rigidity after the measuring rod is lengthened. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] like Figure 1 - Figure 4 As shown, the present invention proposes a measuring wheel type soil internal deformation measuring device for concealed filling projects, including a mounting plate 1. A support rod 2 is mounted on the upper part of the mounting plate 1. A measuring wheel shaft 3 is rotatably connected to the side of the support rod 2. A measuring wheel 4 is mounted on the outer side of the measuring wheel shaft 3. A steel wire 6 is movably connected to the side of the measuring wheel 4. A settlement plate 7 is mounted on the end of the steel wire 6 away from the measuring wheel 4. A predetermined tension rope 9 is symmetrically mounted on the upper part of the mounting plate 1. The ends of the two predetermined tension ropes 9 away from the mounting plate 1 are fixedly connected to the measuring wheel shaft 3.

[0018] The outer side of the steel wire 6 is fitted with a steel wire outer sleeve 8.

[0019] A rotating rod 5 is rotatably connected to the side of the measuring wheel 4. The rotating rod 5 is located in a non-central position of the measuring wheel 4. The steel wire 6 is installed on the side of the rotating rod 5.

[0020] The upper part of the mounting plate 1 is equipped with a measuring wheel test settlement plate data recording and storage chip 10, which is used to store the settlement data measured by the measuring wheel 4.

[0021] The steel wire 6 is made of indium steel and is used to transmit the internal deformation of the soil to the measuring wheel 4.

[0022] The predetermined tension rope 9 applies a predetermined tension to the measuring wheel shaft 3 to maintain the tension between the measuring wheel 4 and the steel wire 6.

[0023] The rotating rod 5 can rotate around its connection point with the measuring wheel 4, and is used to convert the linear displacement of the steel wire 6 into the rotational motion of the measuring wheel 4.

[0024] The settlement plate 7 is embedded inside the fill soil and is used to move the steel wire 6 as the soil deforms.

[0025] In this embodiment, when it is necessary to measure the internal deformation of the soil, the mounting plate 1 is first installed on the ground to support the support rod 2 and the measuring wheel shaft 3. Then, the settlement plate 7 is first buried in the soil. Then, a predetermined tension is applied to the measuring wheel shaft 3 and the measuring wheel 4 through two predetermined tension ropes 9, thereby maintaining the tension between the measuring wheel 4 and the steel wire 6 and providing stable initial tension conditions for measurement. When the backfill soil settles or bulges, the settlement plate 7 will move synchronously with the soil. Since the predetermined tension ropes 9 are preset with a predetermined tension... The movement of the settlement plate will cause the steel wire 6 connected to it to be displaced. The movement of the steel wire 6 will cause the measuring wheel 4 to rotate around the measuring wheel shaft 3. The rotation angle or rotation amount of the measuring wheel 4 is related to the settlement or swelling of the soil. The measuring wheel test settlement plate data recording and storage chip 10 is connected to the measuring wheel shaft 3, which can record the rotation information of the measuring wheel 4 in real time, such as the rotation angle and the number of rotations, and convert these data into specific values ​​of soil settlement or swelling, thereby realizing accurate measurement and long-term monitoring of the settlement or swelling deformation of the fill soil in the area.
