Description

Technical Field

[0001] This utility model relates to the technical field of support structures, specifically an auxiliary support structure for highway engineering construction. Background Technology

[0002] Highway engineering refers to the surveying, measurement, design, construction, maintenance, and management of highway structures. Highway engineering structures include: roadbed, pavement, bridges, culverts, tunnels, safety protection facilities, etc.

[0003] In the construction process of highway engineering, support structures are frequently used to reinforce and protect the inner walls of the excavated foundation pits. Support structures are a crucial type of infrastructure. However, conventional support structures only provide simple support and lack the ability to test the stability of the foundation pit. While the foundation pit may not collapse during the support structure's operation, it must be removed when highway infrastructure needs to be installed within the roadbed. After removal, the foundation pit may deform due to its low structural stability, potentially leading to collapse. Therefore, a support structure capable of testing the structural strength of the foundation pit during support is needed to meet these requirements. To address this, those skilled in the art have proposed an auxiliary support structure for highway engineering construction to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary support structure for highway engineering construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A highway construction auxiliary support structure includes a base plate, with wheels mounted on the bottom end of the base plate, fixing components mounted at the corners of the base plate, a frame plate mounted on the top of the base plate, a control box mounted on the top of the frame plate, expansion joints mounted laterally on both outer walls of the frame plate, support plates mounted on the opposite ends of the two expansion joints, and a plurality of detection inserts mounted at equal intervals on the opposite ends of the two support plates. The detection inserts are parallel to the expansion joints, and after being inserted into the inner wall of the pit, they can detect the strength of the layered structure of the pit.

[0007] As a further embodiment of this utility model: the outer side wall of the support plate is provided with a plurality of movable grooves at equal intervals, a vertical rod is installed on the inner top surface of the movable groove, a pressure detector is installed on the inner bottom surface of the movable groove, one end of the detection insert is placed in the movable groove and is inserted and connected to the vertical rod, the outer wall of the portion of the detection insert placed in the movable groove is slidably attached to the inner side wall of the movable groove, the top end of the pressure detector is connected to the bottom end of the elastic element, and the top end of the elastic element is connected to the bottom end of the detection insert.

[0008] As a further embodiment of this utility model: the upper part of the elastic element is sleeved on the lower part of the vertical rod, and the bottom end of the vertical rod is close to the top end of the pressure detector but does not contact the top end of the pressure detector.

[0009] As a further embodiment of this utility model: bracket rods are installed on both sides of the base plate, and a semi-circular ring plate is connected to the top of the bracket rod. The inner shape and size of the semi-circular ring plate correspond to the outer shape and size of the telescopic part of the telescopic member. The semi-circular ring plate is used to support the telescopic part of the telescopic member.

[0010] As a further embodiment of this utility model: the fixing component includes a threaded sleeve installed at the corner of the base plate, a threaded rod threadedly connected to the threaded sleeve, a throttle connected to the top of the threaded rod, and a grounding plug connected to the bottom of the threaded rod.

[0011] This utility model has the following advantages: The support structure moves the support plate through the telescopic component, thereby adjusting the distance between the two support plates. This allows for the support of foundation pits with different inner diameters. When the support plate is in contact with the inner wall of the foundation pit, the detection plate is also inserted into the inner wall of the foundation pit. Since the detection plates are evenly spaced along the vertical direction, different detection plates can be inserted into different layers of soil in the foundation pit. When the soil in a certain area of ​​the foundation pit is loose and about to collapse, the downward pressure on the detection plate at the corresponding position below it will be higher than that on other detection plates. This pressure difference can be visually detected and displayed by a pressure detector, thus reminding construction personnel to reinforce the unstable area. This ensures that the foundation pit will not collapse after the support structure is removed, guaranteeing the safety and stability of highway construction. Attached Figure Description

Detailed Implementation

[0017] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0018] Example 1: Please refer to Figures 1 to 4 A highway construction auxiliary support structure includes a base plate 2, with a driving wheel 3 installed at the bottom end of the base plate 2, a fixing component 4 installed at the corner of the base plate 2, a frame plate 9 installed at the top end of the base plate 2, a control box 10 installed at the top end of the frame plate 9, expansion joints 11 installed laterally on both outer walls of the frame plate 9, support plates 14 installed at the opposite ends of the two expansion joints 11, and a plurality of detection inserts 15 installed at equal intervals at the opposite ends of the two support plates 14. The detection inserts 15 are parallel to the expansion joints 11, and after the detection inserts 15 are inserted into the inner wall of the pit 1, they can detect the strength of the layered structure of the pit 1.

[0019] Please see Figure 1 , Figure 3 The outer side wall of the support plate 14 is provided with a plurality of movable grooves 16 at equal intervals. A vertical rod 17 is installed on the inner top surface of the movable groove 16, and a pressure detector 18 is installed on the inner bottom surface of the movable groove 16. One end of the detection insert 15 is placed in the movable groove 16 and is inserted and connected to the vertical rod 17. The outer wall of the portion of the detection insert 15 placed in the movable groove 16 is slidably attached to the inner side wall of the movable groove 16. The top end of the pressure detector 18 is connected to the bottom end of the elastic member 19. The top end of the elastic member 19 is connected to the bottom end of the detection insert 15. The upper part of the elastic member 19 is sleeved on the lower part of the vertical rod 17. The bottom end of the vertical rod 17 is close to the top end of the pressure detector 18 but does not contact the top end of the pressure detector 18.

[0020] Example 2: See Figure 1 , Figure 2Based on Embodiment 1, bracket rods 12 are installed on both sides of the base plate 2. A semi-circular ring plate 13 is connected to the top of the bracket rod 12. The inner shape and size of the semi-circular ring plate 13 correspond to the outer shape and size of the telescopic part 11. The semi-circular ring plate 13 is used to support the telescopic part 11 to reduce the vertical pressure on the telescopic part 11. The telescopic part 11 is selected as an electric telescopic rod. The two ends of the telescopic part 11 are connected to mounting plates to be installed on the frame plate 9 and the support plate 14 respectively. The pressure detector 18 and the telescopic part 11 are both connected to the control box 10. The control box 10 is equipped with an operation panel with a display screen.

[0021] Please see Figure 1 , Figure 4 The fixing component 4 includes a threaded sleeve 5 installed at the corner of the base plate 2, a threaded rod 6 threadedly connected to the threaded sleeve 5, a throttle 8 connected to the top of the threaded rod 6, and a grounding plug 7 connected to the bottom of the threaded rod 6.

[0022] Working principle: The base plate 2 moves within the pit 1 via the driving wheels 3. After the base plate 2 moves to the working area, the handle 8 is rotated to move the threaded rod 6 downwards, which in turn moves the grounding rod 7 downwards, so that the bottom of the grounding rod 7 is inserted into the bottom of the pit 1, thereby fixing the position of the base plate 2. Then, the telescopic component 11 moves the support plate 14 until the outer wall of the support plate 14 is in contact with the inner wall of the pit 1. The detection plate 15 is also inserted laterally into the pit 1. After a period of time, the pressure detector 18 detects the pressure on each detection plate 15. When a part of the side of the pit 1 becomes loose or is about to collapse, The soil in the area will press down on the detection plate 15 below. The detection plate 15 is compressed and squeezes the elastic element 19. The elastic element 19 is compressed and squeezes the corresponding pressure detector 18 below. The pressure detector 18 can detect the downward movement of the soil in the area. By comparing the values ​​of different pressure detectors 18, the detection structure is transmitted to the control box 10 and displayed, so that the construction personnel can make early warnings and take additional reinforcement measures to further reinforce the foundation pit 1. This ensures that the foundation pit 1 will not collapse after the support structure is removed when the foundation of the highway construction equipment is installed later, thus ensuring the stability and safety of the construction.
