Description

Technical Field

[0001] The utility model relates to the technical field of aqueduct construction, in particular to a construction device for aqueduct top pull rods in water conservancy projects. Background Art

[0002] U-shaped aqueduct is a commonly used water conveyance aqueduct in water conservancy projects. In order to share the water pressure generated when water passes through the aqueduct and ensure the overall force stability of the aqueduct body, it is necessary to cast tie rods on the top of the aqueduct to restrain the deformation of the aqueduct body. At present, when casting the tie rods on the top of the aqueduct, it is usually adopted to set up support brackets from the bottom of the trough to the top of the trough, and then install the formwork, tie the steel bars, and finally pour the concrete.

[0003] The bottom of a large U-shaped aqueduct is at a high altitude from the top, and construction workers need to assemble formwork and tie steel bars at high altitudes, which poses a great safety risk. The construction of supporting brackets is also time-consuming and labor-intensive, affecting construction efficiency. In addition, the interior of the U-shaped aqueduct serves as a construction channel, and the installation of supporting brackets seriously affects the transportation of materials inside the aqueduct. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a construction device for aqueduct top pull rods in water conservancy projects, which can improve construction efficiency, reduce construction costs and save space.

When the output end of the lifting drive mechanism is located at the bottom of the aqueduct, the casting platform is built at the bottom of the trough and connected to the output end of the lifting drive mechanism. When the lifting drive mechanism drives the built casting platform to rise to the construction position, the casting platform is locked and fixed to the trough top bracket.

[0007] As a further improvement of the above technical solution:

[0008] The casting platform includes a template frame, which is connected to the output end of the lifting drive mechanism. A plurality of load-bearing beams are evenly spaced at the bottom of the template frame. Fasteners are provided at both ends of each load-bearing beam to lock and fix the template frame to the trough top bracket when the template frame rises to the construction position.

[0009] The template frame is divided into multiple sections, each section includes a bottom plate and a side plate, the end of the side plate is folded outward to have a connecting edge, and the connecting edges of adjacent side plates are tightly attached to each other and fixed by bolts.

[0010] The fastener includes a screw and a plurality of locking nuts. The lower end of the screw is passed through the load-bearing beam and is locked and fixed by a locking nut. When the template frame rises to the construction position, the upper end of the screw passes through the slot top bracket and is locked and fixed by a locking nut.

[0011] The slot top bracket is provided with a sliding slot for the screw rod to pass through.

[0012] The lifting drive mechanism comprises a winch and a steel wire rope, one end of the steel wire rope is connected to the winch, and the other end is connected to the casting platform.

[0013] It also includes an assembly platform for building the casting platform, the assembly platform includes a support frame and a support plate, the support frame is arranged on the bottom of the aqueduct, the support plate is overlapped on the support frame and forms support for the constructed casting platform.

[0015] The assembly platform also includes a plurality of leveling parts, each of which is fixed on each of the vertical beam tubes.

[0016] The leveling member comprises a fixing nut and an adjusting bolt. The fixing nut is fixedly connected to the vertical beam tube. The adjusting bolt is threadedly connected to the fixing nut and supports the support plate.

[0017] Compared with the prior art, the advantages of the utility model are:

[0018] During construction, first set up the trough top support on the top of the aqueduct according to the tie rod construction position, and install the lifting drive mechanism, then build the casting platform at the bottom of the trough. After the construction is completed, the casting platform is connected to the output end of the lifting drive mechanism, and then the lifting drive mechanism is started to drive the casting platform to the construction position to carry out the casting construction of the tie rod. Compared with the traditional aqueduct tie rod construction, this device lifts the casting platform to the construction position through the lifting drive mechanism, and does not need to install and remove the support bracket, especially when carrying out tie rod construction at multiple points, which reduces a lot of workload and improves construction efficiency. At the same time, after the casting platform is assembled at the bottom of the trough, it is lifted to the construction position and fixed to the trough top support by the lifting drive mechanism.
