Description

Technical Field

[0001] This utility model relates to the field of foundation pit measurement technology, specifically a deep foundation pit engineering measurement device. Background Technology

[0002] Deep foundation pits specifically refer to projects that meet one of the following conditions: excavation depth exceeding 5 meters; three or more basement levels; or projects with complex geological conditions, sensitive surrounding environment, proximity to important buildings or structures, or dense underground pipelines, even if the depth is less than 5 meters. Foundation pit engineering mainly includes support system design and construction, earthwork excavation, water uplift and monitoring, etc., and is a comprehensive system engineering project involving geotechnical engineering and structural engineering.

[0003] During the construction of deep foundation pit projects, high-precision, real-time, and automated monitoring of the horizontal displacement of the foundation pit support structure and the settlement of the deep soil is crucial to ensuring project safety. Before measurement, holes need to be drilled, and then measuring tubes are inserted into the holes to detect the inclination. Settlement equipment is then used to detect the settlement.

[0004] When drilling, the holes are prone to tilting. After the measuring tube is placed inside, it is easy to cause errors in the measurement results, thus affecting the accuracy of the measurement results. Furthermore, drilling first and then measuring is more cumbersome and can reduce the efficiency of deep foundation pit engineering measurement. At the same time, multiple devices are needed to detect the tilt and settlement of the foundation pit, which can easily lead to inconsistent data and increase the measurement cost.

[0005] Therefore, this utility model provides a deep foundation pit engineering measurement device to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved This invention provides a deep foundation pit engineering measurement device, which aims to solve the problems mentioned in the background art.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A deep foundation pit engineering surveying device includes a support frame and a surveying integrated tube. An installation plate is fixedly installed on the inner wall of the support frame. A take-up roller is rotatably installed on the side wall of the installation plate via a rotating shaft. A wire is wound around the outer surface of the take-up roller. A socket is fixedly installed at one end of the wire. A handle is rotatably installed on the side wall of the take-up roller. A plug is fixedly installed at one end of the surveying integrated tube. The plug and the socket are mutually compatible. A positioning component is provided on the outer surface of the surveying integrated tube. The positioning component includes a fixed plate and a leveling plate. The inner wall of the fixed plate is fixedly connected to the outer surface of the measuring integrated tube. A limit strip is fixedly installed on the outer surface of the measuring integrated tube. A limit plate is fixedly installed at one end of the limit strip. The inner wall of the leveling plate is provided with a moving hole that is compatible with the measuring integrated tube and the limit strip. The limit strip can limit the leveling plate and ensure the direction of movement of the leveling plate on the measuring integrated tube. The limit plate can prevent the leveling plate from falling off the measuring integrated tube.

[0008] As a preferred technical solution of this application, the leveling plate is slidably connected to the outer surface of the measuring integrated tube through a moving hole. The leveling plate is located between the limiting plate and the fixed plate. A limiting rod is fixedly installed on the side wall of the fixed plate, and a sliding hole corresponding to the limiting rod is provided on the inner wall of the leveling plate.

[0009] As a preferred technical solution of this application, the wall of the sliding hole slides in contact with the outer surface of the limiting rod, and a plurality of insertion rods are provided on the side wall of the leveling plate. One end of the insertion rod, the limiting rod, and the other end of the measuring integrated tube are all set as pointed. Setting one end of the insertion rod, the limiting rod, and the measuring integrated tube as pointed can reduce the friction between the insertion rod, the limiting rod, and the measuring integrated tube and the soil, making it easier for the insertion rod, the limiting rod, and the measuring integrated tube to be inserted into the soil better and faster.

[0010] As a preferred technical solution of this application, four mounting slots are provided on the other side wall of the leveling plate, and a level is fixedly installed on the inner wall of each of the four mounting slots. Two of the level instruments are placed horizontally, and the other two are placed vertically. The level instruments facilitate the observation of the leveling plate's levelness, ensuring the levelness of the leveling plate, thereby ensuring the levelness of the measuring integrated pipe in the soil.

[0011] As a preferred technical solution of this application, the outer surface of the measuring integrated tube is provided with a plurality of anchoring points, the distance between the anchoring points is the same, and the outer surface of the anchoring points is provided with a settling magnetic ring.

[0012] As a preferred technical solution of this application, the inner wall of the measuring integrated tube is provided with a tilt measuring guide groove, and the inner wall of the tilt measuring guide groove is provided with a tilt measuring sensor.

[0013] (III) Beneficial Effects By setting up positioning components, the leveling plate is first determined by a level, and then fixed by a rod. Under the action of the leveling plate, the measuring integrated tube is inserted into the pit wall, ensuring the levelness of the measuring integrated tube with the deep foundation pit wall. This effectively prevents the measuring integrated tube from tilting in the soil, thus ensuring the accuracy of the measurement data for deep foundation pit projects and effectively improving the quality and safety of deep foundation pit projects. At the same time, the inclination and settlement functions are integrated into one measuring tube. Compared with traditional measurement methods, this achieves the functions of both sides of one tube, reduces costs, and ensures the consistency and synchronization of data.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides a deep foundation pit engineering surveying device, such as... Figures 1-5As shown, the deep foundation pit engineering measurement device includes a support frame 1 and a measurement integrated tube 5. An installation plate is fixedly installed on the inner wall of the support frame 1. A take-up roller 2 is rotatably installed on the side wall of the installation plate via a rotating shaft. A wire 3 is wound around the outer surface of the take-up roller 2. A socket 4 is fixedly installed at one end of the wire 3. A handle is rotatably installed on the side wall of the take-up roller 2. A plug 6 is fixedly installed at one end of the measurement integrated tube 5. The plug 6 and the socket 4 are mutually compatible. A positioning component 7 is provided on the outer surface of the measurement integrated tube 5. The positioning component 7 includes a fixed plate 71 and a leveling plate 74. The inner wall of the fixed plate 71 is fixedly connected to the outer surface of the measuring integrated tube 5. A limit strip 73 is fixedly installed on the outer surface of the measuring integrated tube 5. A limit plate 711 is fixedly installed at one end of the limit strip 73. The inner wall of the leveling plate 74 is provided with a moving hole 75 that is compatible with the measuring integrated tube 5 and the limit strip 73.

[0017] The leveling plate 74 is slidably connected to the outer surface of the measuring integrated tube 5 through the moving hole 75. The leveling plate 74 is located between the limiting plate 711 and the fixed plate 71. The limiting rod 72 is fixedly installed on the side wall of the fixed plate 71. The inner wall of the leveling plate 74 is provided with sliding holes 79 corresponding to the limiting rod 72.

[0018] The wall of the sliding hole 79 slides in contact with the outer surface of the limiting rod 72. Several insertion rods 76 are provided on the side wall of the leveling plate 74. One end of the insertion rod 76, one end of the limiting rod 72, and the other end of the measuring integrated tube 5 are all set as pointed.

[0019] Four mounting slots 77 are provided on the other side wall of the leveling plate 74. A level 78 is fixedly installed on the inner wall of each of the four mounting slots 77. Two of the level 78 are placed horizontally, and the other two are placed vertically.

[0020] Specifically, by setting the positioning component 7, the horizontal or vertical position of the measuring integrated tube 5 when inserted into the soil can be guaranteed. The take-up roller 2 is placed at the pit opening of the deep foundation pit by the support frame 1, and then the take-up roller 2 is rotated on the support frame 1 by the throttle. As the take-up roller 2 rotates, the wire 3 is loosened and the length of the wire 3 is placed in an appropriate position. Then, the insertion rod 76 on the leveling plate 74 is inserted into the soil, so that the side wall of the leveling plate 74 is in contact with the pit wall. The level of the leveling plate 74 is observed by the level 78 on the leveling plate 74 to determine whether the leveling plate 74 is in a horizontal state. After the leveling plate 74 is adjusted to a horizontal state, the measuring integrated tube 5 and the limiting rod 72 are driven into the soil by the fixing plate 71. The limiting rod 72 ensures the horizontality of the measuring integrated tube 5 when it moves in the soil, so that the measuring integrated tube 5 is in a vertical state with the pit wall after it is fully inserted into the soil. Then, the socket 4 on the wire 3 is connected to the plug 6 on the measuring integrated tube 5.

[0021] The outer surface of the measuring integrated tube 5 is provided with several anchor points 8, and the distance between the anchor points 8 is the same. The outer surface of the anchor points 8 is provided with a settling magnetic ring 9.

[0022] An inclinometer guide groove 10 is provided on the inner wall of the measuring integrated tube 5, and an inclinometer sensor 11 is provided on the inner wall of the inclinometer guide groove 10.

[0023] Specifically, by setting up a measurement integrated tube 5, after the measurement integrated tube 5 is fully inserted into the soil of the pit wall, the settlement magnetic ring 9 is fixed at an appropriate anchoring point 8 according to the specific situation of the measurement integrated tube 5, so that the settlement magnetic ring 9 comes into contact with the pit wall. During the placement process, the settlement magnetic ring 9 monitors the settlement or bulging of the pit wall. The inclination sensor 11 inside the measurement integrated tube 5 monitors the inclination of the measurement point, and then the data is displayed on the display. The settlement magnetic ring 9 and the inclination sensor 11 are existing technologies in this field, and the data transmission is also existing technology in this field, so it will not be described in detail.
