Description

Technical Field

[0001] This utility model relates to the field of foundation pit support technology, specifically a foundation pit support and reinforcement device. Background Technology

[0002] An excavation pit is a pit-shaped structure temporarily excavated during construction to carry out underground structure construction (such as basements, subway tunnels, underground parking garages, etc.), and it can be considered a core part of building foundation construction. Depending on geological conditions, excavation pits can be classified into various categories, such as soft soil pits, rock pits, and sand pits. In practical applications, these different types of excavation pits often face a series of problems, including instability of the support structure, sudden heave at the bottom of the pit, surrounding settlement, quicksand, and piping. Therefore, it is necessary to install excavation pit support and reinforcement devices to enhance the stability of the excavation pit.

[0003] Existing foundation pit support and reinforcement devices typically employ multiple reinforcing rods on the inner side of the protective side plate to enhance its stability, with the other end of each rod fixed to the bottom of the pit. However, these reinforcing rods, being in contact with the pit bottom, occupy a significant amount of working space, potentially interfering with construction. Furthermore, the greater the distance between the top of the protective side plate and the bottom of the pit, the less effective the reinforcement becomes. To avoid excessive space occupation and minimize the impact on construction, while simultaneously improving reinforcement efficiency, this application proposes a novel foundation pit support and reinforcement device. Utility Model Content

[0004] The purpose of this utility model is to provide a foundation pit support and reinforcement device to solve the problems that the reinforcing rods of existing foundation pit support processing devices may excessively occupy the foundation pit space, affecting construction, and that the greater the distance between the protective side plate and the bottom of the foundation pit, the less ideal the processing effect of the reinforcing rods becomes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foundation pit support and reinforcement device, comprising four mounting rods, with multiple reinforcing rod components respectively arranged on one side of the four mounting rods close to each other, two rod fixing components symmetrically arranged at both ends of the multiple reinforcing rod components, multiple protective plates respectively arranged on the outer side of the reinforcing rod components, two rod reinforcing blocks symmetrically arranged at both ends of the top of the multiple protective plates near the reinforcing rod components, and two plate reinforcing blocks symmetrically arranged at both ends of the bottom of the protective plates near the mounting rods;

[0006] The reinforcing rod component includes a supporting reinforcing rod, and two connecting rods are symmetrically threaded to the inner sides of both ends of the supporting reinforcing rod. The two connecting rods are symmetrically rotatably connected to two connecting plates at one end away from each other.

[0007] The mounting rod includes a mounting base plate, and a fixed mounting rod is fixedly connected to the upper surface of the mounting base plate. The mounting base plate is connected to the ground at the bottom of the foundation pit by expansion screws.

[0008] The bottom surfaces of the two plate reinforcing blocks are fixedly connected to the upper surfaces of the two mounting base plates, and the vertical surfaces of the plate reinforcing blocks are fixedly connected to both ends of the protective plate.

[0009] The rod fixing component includes a fixed sleeve, a movable sleeve rotatably connected to one side of the fixed sleeve, a sleeve flange fixedly connected to the other side of the fixed sleeve, a sliding connection between the inner side of the fixed sleeve and the fixed mounting rod, and the other side of the movable sleeve bypassing the fixed mounting rod and connected to the fixed sleeve by screws.

[0010] The two connecting plates are respectively connected to two flanges at both ends by screws.

[0011] The inner sides of the two rod reinforcing blocks are fixedly connected to both ends of the supporting reinforcing rod, and the other end of the rod reinforcing block is fixedly connected to both ends of the protective plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses four mounting rods to fix the four corners, and multiple reinforcing rod components are connected to the four mounting rods through two rod fixing components at both ends, which can strengthen the structure of the four mounting rods. Then, the two rod reinforcing blocks at both ends of the reinforcing rod components are fixed to the protective plate, which can increase the contact area between the protective plate and the reinforcing rod components, thereby better supporting the protective plate, avoiding occupying the pit working space, ensuring construction, and the top of the protective plate can be stably supported and reinforced by the reinforcing rod components.

[0014] 2. This utility model uses two reinforcing blocks at both ends of the bottom of the protective plate to fix the bottom of the protective plate to the two mounting base plates at both ends, thereby fixing the bottom of the protective plate to the two mounting rods at both ends, ensuring that the bottom of the protective plate can be stably supported and improving the structural strength.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a foundation pit support and reinforcement device, including four mounting rods 1, with multiple reinforcing rod components 2 respectively arranged close to each other on one side of the four mounting rods 1, two rod fixing components 3 respectively symmetrically arranged at both ends of the multiple reinforcing rod components 2, multiple protective plates 4 respectively arranged on the outside of the reinforcing rod components 2, two rod reinforcing blocks 5 respectively symmetrically arranged at both ends of the top of the multiple protective plates 4 close to the reinforcing rod components 2, and two plate reinforcing blocks 6 respectively symmetrically arranged at both ends of the bottom of the protective plates 4 close to the mounting rods 1;

[0022] The reinforcing rod component 2 includes a supporting reinforcing rod 201. Two connecting rods 202 are symmetrically threaded to the inner sides of both ends of the supporting reinforcing rod 201. Two connecting plates 203 are symmetrically rotatably connected to the two connecting rods 202 at one end away from each other. The two connecting rods 202 are threadedly connected to the supporting reinforcing rod 201, which allows the extension distance of the two connecting rods 202 to be adjusted, so that the two connecting plates 203 can be fixed to the two sleeve flanges 303 at both ends.

[0023] The mounting rod 1 includes a mounting base plate 101, and a fixed mounting rod 102 is fixedly connected to the upper surface of the mounting base plate 101. The mounting base plate 101 is connected to the ground at the bottom of the foundation pit by expansion screws. By setting the mounting base plate 101, the contact area with the ground at the bottom of the foundation pit can be increased, the bearing capacity can be improved, and the foundation pit sidewall can be supported more stably.

[0024] The bottom surfaces of the two plate reinforcing blocks 6 are fixedly connected to the upper surfaces of the two mounting base plates 101, and the vertical surfaces of the plate reinforcing blocks 6 are fixedly connected to both ends of the protective plate 4. By setting the two plate reinforcing blocks 6, the protective plate 4 can be fixed to the two mounting base plates 101, which facilitates better support of the protective plate 4 and improves the structural strength.

[0025] The rod fixing component 3 includes a fixing sleeve 301, a movable sleeve 302 rotatably connected to one side of the fixing sleeve 301, and a flange 303 fixedly connected to the other side of the fixing sleeve 301. The inner side of the fixing sleeve 301 is slidably connected to the fixed mounting rod 102. The other side of the movable sleeve 302 passes around the fixed mounting rod 102 and is connected to the fixing sleeve 301 by screws. By connecting the movable sleeve 302 and the fixing sleeve 301 by screws, the fixing sleeve 301 and the movable sleeve 302 can be pressed tightly against the fixed mounting rod 102, thereby fixing both ends of the reinforcing rod component 2.

[0026] The two connecting plates 203 are connected to the two flanges 303 at both ends by screws.

[0027] The inner sides of the two rod reinforcing blocks 5 are fixedly connected to both ends of the support reinforcing rod 201, and the other end of the rod reinforcing block 5 is fixedly connected to both ends of the protective plate 4. By setting the two rod reinforcing blocks 5, the support reinforcing rod 201 and the protective plate 4 can be fixed, which facilitates better support of the protective plate 4.

[0028] Working principle: Place the four mounting rods 1 into the four corners inside the foundation pit. Fix the mounting base plate 101 to the bottom of the foundation pit using expansion screws. Align the fixing sleeve 301 with the fixing mounting rod 102 and insert it. Then, pass the movable sleeve 302 around the fixing mounting rod 102 and connect the movable sleeve 302 to the fixing sleeve 301 using screws. This allows the movable sleeve 302 and the fixing sleeve 301 to press against the inner fixing mounting rod 102. Rotate the connecting rod 202 at one end of the support reinforcing rod 201 so that the connecting plate 203 fits into the sleeve at one end. The flange 303 is attached and then fixed with screws. Then, the connecting rod 202 at the other end is rotated so that the connecting plate 203 at the other end is fixed to the flange 303 at the other end. Then, the reinforcing rod component 2 is installed. Then, multiple protective plates 4 are inserted into the gaps between the multiple reinforcing rod components 2 and the side wall of the pit. The bottom ends of the protective plates 4 are fixed to the two mounting base plates 101 respectively through two plate reinforcing blocks 6. Then, the protective plates 4 are fixed to the two ends of the supporting reinforcing rod 201 respectively through two rod reinforcing blocks 5, thus completing the installation.
