Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of bridge pier construction, and specifically discloses an energy dissipation device for pouring concrete for piers. Background Technology
[0002] During bridge pier construction, to facilitate on-site work, concrete is typically delivered to the top of the pier using a truck-mounted pump or crane. A tremie pipe is installed inside the pier, through which the concrete flows to the working surface. The tremie pipe is a common auxiliary device for concrete pouring in bridge pier construction, and its function is to reduce concrete segregation.
[0003] However, when the tremie pipe is long during construction, the concrete often undergoes segregation due to the separation of the aggregate during the descent process. When the concrete reaches the inner pouring surface of the pier, its workability is poor, making it difficult to guarantee the appearance and quality of the pier, and may even lead to rework, which increases costs. Utility Model Content
[0004] This utility model provides an energy dissipation device for concrete pouring in pier columns, in order to solve the technical problem that the concrete segregates during the descent of the tremie pipe when the tremie pipe is long during construction.
[0005] The energy dissipation device for concrete pouring of pier columns provided by this utility model includes a square tremie cylinder, an impeller, a hinge, a spring, and a base plate. The square tremie cylinder is formed by a first side plate, a second side plate, a third side plate, and a fourth side plate, with the first and third side plates facing each other, and the second and fourth side plates facing each other. The impeller is rotatably installed inside the square tremie cylinder. The base plate is located below the square tremie cylinder and is connected to the first and third side plates of the square tremie cylinder by a hinge, and to the second and fourth side plates of the square tremie cylinder by a spring. The base plate closes the lower end of the square tremie cylinder by the spring.
[0006] The aforementioned energy dissipation device for concrete pouring of pier columns also includes a fixed shaft; the fixed shaft passes through two opposite side plates in the square tremie tube, and the end located outside the square tremie tube has a threaded end and is fixed by bolts; the impeller includes a wheel shaft and blades fixed on the wheel shaft, and the wheel shaft is rotatably sleeved on the fixed shaft.
[0007] The aforementioned energy dissipation device for concrete pouring of pier columns also includes a hook fixing ring and a hook; the two opposite side plates in the square duct are fixed with hook fixing rings, and hooks are hung on the hook fixing rings.
[0008] In the aforementioned energy dissipation device for concrete pouring of pier columns, the upper end of the spring is connected to the square tremie cylinder via a fixing ring I, and the lower end of the spring is connected to the base plate via a fixing ring II.
[0009] In the aforementioned energy dissipation device used for concrete pouring of pier columns, the square tremie cylinder, impeller, hinge, spring, and base plate are all made of steel.

The lower end of the spring is connected to a fixed ring II, which is made of bent steel bars and welded to a base plate.
[0010] Compared with the prior art, the present invention has the following beneficial effects: The above-mentioned device is easy to operate, and the components are simple to process and assemble on site. The square tremie pipe is connected to the lower end of the upper tremie pipe. The concrete falls onto the impeller through the square tremie pipe.

[0016] This embodiment provides an energy dissipation device for concrete pouring in pier columns, including a square tremie cylinder 3, an impeller 4, a hinge 7, a spring 9, and a base plate 11. The square tremie cylinder 3 is formed by a first side plate, a second side plate, a third side plate, and a fourth side plate, with the first and third side plates facing each other, and the second and fourth side plates facing each other. The impeller 4 is rotatably installed inside the square tremie cylinder 3. The base plate 11 is located below the square tremie cylinder 3 and is connected to the first and third side plates of the square tremie cylinder 3 via the hinge 7, and to the second and fourth side plates of the square tremie cylinder 3 via the spring 9. The base plate 11 closes the lower end of the square tremie cylinder 3 via the spring 9.
[0017] The energy dissipation device for concrete pouring of pier columns mentioned above also includes a fixed shaft 5; the fixed shaft 5 passes through two opposite side plates in the square tremie cylinder 3, and the end located outside the square tremie cylinder 3 has a threaded end and is fixed by bolts 6; the impeller 4 includes a wheel shaft and blades fixed on the wheel shaft, and the wheel shaft is rotated and sleeved on the fixed shaft 5, thereby realizing free rotation.
[0018] The energy dissipation device used for concrete pouring of pier columns also includes a hook fixing ring 1 and a hook 2; the hook fixing ring 1 is fixed on the outer side of the two opposite side plates in the square duct 3, and the hook fixing ring 1 is hung with a hook 2.
[0019] In the above-mentioned energy dissipation device for concrete pouring of pier columns, the upper end of spring 9 is connected to square tremie cylinder 3 through fixing ring I8, and the lower end of spring 9 is connected to base plate 11 through fixing ring II10.
[0020] In the above-mentioned energy dissipation device for concrete pouring of pier columns, the square tremie cylinder 3, impeller 4, hinge 7, spring 9 and base plate 11 are all made of steel.

Once the concrete reaches a certain weight, the spring 9 connecting to the base plate 11 extends, and the base plate 11 opens via the hinge 7, allowing the entire concrete to be discharged onto the working surface. As the concrete pouring height on the working surface increases, the tremie pipe above the square tremie pipe 3 must be removed when dismantling the tremie pipe, while the square tremie pipe 3 remains.
