[0002] The scale of underwater concrete pouring is getting larger and larger. In the process of underwater concrete pouring with the conduit method, the conduit is required to be buried in the concrete to a certain depth. Due to reasons such as concrete supply, the conduit for pouring is often buried for too long. It will be difficult to pull out the tube during the next time the tube is pulled out, and it is easy to cause "broken piles", which will seriously affect the quality and progress of the project

The invention relates to a two-way resonance pull-out device of underwater concrete perfusion conduit which is a conduit device for helping to pull out underwater perfused concrete in civil engineering and consists of a vibrator, a lifting ring, a jack lifting support, a vibrator I, two lateral I steel beams, a U-shaped bolt, a big nut, two I steel beams, a steel plate, a lateral steel plate, a semicircular steel plate, a steel plate I and a steel pipe, wherein, the big nut is arranged on the steel pipe, the upper end of the steel pipe is provided with the steel plate on which two I steel beams are arranged, the lower end surfaces of the two I steel beams are provided with the jack lifting supports, the steel plates are arranged on the two I steels, the vibrators are attached to the steel plates I with both ends being provided with the lifting rings, one side of the steel plate is provided with two lateral I steel beams, the side surface of each lateral I steel beam is provided with the lateral steel plate, the lower part of each lateral steel plate is provided with the U-shaped bolt and the semicircular steel plate, and the vibrator I is arranged on the lateral steel plate. The invention has the advantages that the vibrator and the vibrator I generate compressional and shear wave resonance at the same time, which effectively reduces the viscous force of cast concrete and conduit for perfusion.
Description
Technical field: [0001] The invention is a conduit device used in civil engineering to assist in pulling out underwater pouring concrete. Background technique: [0002] The scale of underwater concrete pouring is getting larger and larger. In the process of underwater concrete pouring with the conduit method, the conduit is required to be buried in the concrete to a certain depth. Due to reasons such as concrete supply, the conduit for pouring is often buried for too long. In the process of pulling out the catheter next time, it will be difficult to pull out the tube, which will easily cause "broken piles", which will have a serious impact on the quality and progress of the project. Invention content: [0003] The purpose of the present invention is to provide a two-way resonance pull-out device for underwater concrete pouring conduits that forms longitudinal and transverse wave resonance and reduces the viscous force between the poured concrete and the pouring conduits; t...
