Abstract
Description
Technical Field
[0001] The present application relates to the technical field of railway construction, and in particular to a foundation reinforcement device for an underpass railway frame bridge. Background Art
[0002] A railway underpass is a bridge structure designed to pass under a railway line, passing roads, pipelines, or other facilities. This structure must ensure safe passage without disrupting railway operations. Foundation reinforcement is crucial for ensuring the stability and safety of railway underpasses. Through appropriate geological surveys, mechanical calculations, and the selection of appropriate reinforcement methods, the bearing capacity and stability of the foundation can be effectively improved, ensuring the safe operation of the bridge.
[0003] The existing reinforcement method is to drive piles with smaller diameters into the foundation to improve the bearing capacity of the foundation through the interaction between the piles and the soil. However, the existing piles have poor stability and will settle under the action of pressure over time, thereby affecting the bearing capacity of the foundation.
[0004] In view of this, the purpose of the present invention is to provide a foundation reinforcement device for an underpass railway frame bridge with better stability. Utility Model Content
[0005] The content of this application is used to briefly introduce concepts that will be described in detail in the detailed description section below. The content of this application is not intended to identify key features or essential features of the technical solution for which protection is sought, nor is it intended to limit the scope of the technical solution for which protection is sought.
[0006] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide a foundation reinforcement device for an underpass railway frame bridge, including a foundation pile, a top surface portion of the foundation pile is concave to form a movable groove, a side wall portion of the movable groove penetrates the side wall of the foundation pile to form a reinforcement groove, a reinforcement rod is movably arranged in the reinforcement groove; a push plate is movably arranged in the movable groove, and the push plate and the reinforcement rod are hinged by a hinged rod; an active rod is rotatably arranged in the movable groove, and the active rod is threadedly connected to the push plate.
[0007] During the working process, due to the provision of reinforcement grooves and reinforcement rods, when the foundation pile needs to be inserted into the soil, the reinforcement rod is hidden in the reinforcement groove for easy insertion; due to the provision of active rods and push plates, after the foundation pile is inserted into the soil, the active rod is rotated, and the push plate can move in the movable groove along the height direction of the foundation pile under the action of the active rod. Since the push plate and the reinforcement rod are hinged by a hinged rod, after the push plate moves, the reinforcement rod can be moved out of the reinforcement groove and inserted into the soil under the drive of the hinged rod; the provision of the reinforcement plate can prevent the foundation pile from settling, thereby improving the stability of the foundation of the underpass railway frame bridge.
[0008] Furthermore, there are two push plates, which are arranged oppositely on both sides of the reinforcement rod;
[0009] Two oppositely arranged thread lines are formed on the active rod, and the thread directions of the two thread lines are opposite. Threaded holes are formed on the push plate, and the threaded holes on the two push plates are respectively matched with the threads of the two thread lines.
[0010] Furthermore, a limit plate is fixedly provided on the active rod at the end of the thread line.
[0011] Furthermore, the top surface and the bottom surface of the reinforcement groove are partially concave to form a movable groove, and the hinge rod is arranged in the movable groove.
[0012] Furthermore, the cross section of the movable groove is square, and the side wall of the push plate is fitted with the inner wall of the movable groove.
[0013] Furthermore, an end of the reinforcing rod away from the active rod forms a tapered portion with a triangular cross section.
[0014] Furthermore, a turntable is provided on the top surface of the foundation pile, the turntable is fixedly connected to the active rod, and a plurality of rotating rods are fixedly installed on the top surface of the turntable.
[0015] Furthermore, a plurality of reinforcement rods are arranged in a circular array along the axis of the foundation pile to form a reinforcement group, and the ends of the hinged rods on the plurality of reinforcement rods away from the reinforcement rods are hinged to the same push plate.
[0016] Furthermore, a plurality of reinforcement groups are arranged in a linear array along the axial direction of the active rod.
[0017] The beneficial effects of this application are:
[0018] 1. The reinforcement rod can be inserted into the soil along the radial direction of the foundation pile to prevent the foundation pile from settling and improve the stability of the foundation of the railway frame bridge.
[0019] Second, the cross section of the moving groove is set to be square, which can prevent the push plate from rotating in the axial direction, so that when the active rod rotates, the push plate can only move in the axial direction of the foundation pile.
[0020] 3. The setting of the turntable and the rotating rod makes it convenient for the staff to manually rotate the active rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.
[0035] A foundation reinforcement device for an underpass railway frame bridge comprises a foundation pile 1, which is used to be inserted into the soil in the foundation, and the bearing capacity of the foundation is improved through the interaction between the foundation pile 1 and the soil; the top surface portion of the foundation pile 1 is concave to form a movable groove 101 with a square cross-section, the side wall portion of the movable groove 101 penetrates the side wall of the foundation pile 1 to form a reinforcement groove 102, a reinforcement rod 103 is movably provided in the reinforcement groove 102, and the side wall of the reinforcement rod 103 is in contact with the inner wall of the reinforcement groove 102; a push plate 104 is movably provided in the movable groove 101, the cross section of the push plate 104 corresponds to the cross section of the movable groove 101, the side wall of the push plate 104 is in contact with the side wall of the movable groove 101, the push plate 104 and the reinforcement rod 103 are hinged by a hinge rod 105, an active rod 106 is rotatably provided in the movable groove 101, and the active rod 106 is threadedly connected to the push plate 104;
[0036] Specifically, there are two push plates 104, which are relatively arranged on both sides of the reinforcement rod 103 along the axial direction of the pile foundation 1. Two relatively arranged thread lines 107 are formed on the active rod 106. The two thread lines 107 are also relatively arranged on both sides of the reinforcement rod 103 along the axial direction of the pile foundation 1 and the thread directions are opposite. Threaded holes 108 are formed through the surface parts of the two push plates 104. The threaded holes 108 on the two push plates 104 are respectively threadedly matched with the two thread lines 107, so that when the active rod 106 rotates, the two push plates 104 can simultaneously approach each other or move away from each other along the axial direction of the active rod 106.
[0037] In the initial state, the reinforcement rod 103 is hidden in the foundation pile 1 to facilitate the insertion of the foundation pile 1 into the soil. After the foundation pile 1 is inserted into the soil, the active rod 106 is rotated, and the two push plates 104 can approach each other along the axial direction of the active rod 106, so that the hinged rod 105 pushes the reinforcement rod 103 out of the reinforcement groove 102. In order to reduce the resistance of the soil, the end of the reinforcement rod 103 away from the active rod 106 forms a cone-shaped portion 114 with a triangular cross-section. After the reinforcement rod 103 moves out of the reinforcement groove 102 and is inserted into the soil, it can prevent the foundation pile 1 from sinking, thereby achieving reinforcement of the foundation.
[0038] Furthermore, in order to prevent the push plate 104 from moving excessively when the active rod 106 rotates, limit plates 109 are fixedly provided at both ends of the thread line 107 on the active rod 106. When the push plate 104 moves to fit with the limit plates 109, the reinforcement rod 103 extends out of the reinforcement groove 102 to its longest length or is completely hidden in the reinforcement groove 102.
[0039] Furthermore, in order to expand the range of movement of the reinforcement rod 103, the top and bottom surfaces of the reinforcement groove 102 are partially concave to form a movable groove 110, and the hinge rod 105 is arranged in the movable groove 110. The arrangement of the movable groove 110 can prevent the hinge rod 105 from interfering with the inner wall of the movable groove 101 when moving, thereby affecting the movement of the reinforcement rod 103;
[0040] Furthermore, in order to facilitate the rotation of the active rod 106, a turntable 111 is provided on the top surface of the pile 1. The turntable 111 is fixedly connected to the active rod 106. Four rotating rods 112 are fixedly installed on the top surface of the turntable 111. By pushing the rotating rods 112, the active rod 106 can be driven to rotate.
[0041] In this embodiment, four reinforcement rods 103 are arranged in a circular array along the axis of the foundation pile 1 to form a reinforcement group 113, and each reinforcement rod 103 is spaced 90° apart. The hinged rods 105 on the four reinforcement rods 103 are hinged to the same push plate 104 at one end away from the reinforcement rod 103; when the active rod 106 is rotated, the two relatively moving push plates 104 can push the four reinforcement rods 103 to move simultaneously from both sides of the reinforcement rod 103; three reinforcement groups 113 are arranged in a linear array along the axial direction of the active rod 106. When the active rod 106 is rotated, the reinforcement rods 103 on the three reinforcement groups 113 can move simultaneously and be inserted into the soil to achieve reinforcement of the foundation of the underpass railway frame bridge.
