Description
Technical Field
[0001] This utility model relates to the field of concrete pouring technology, and in particular to an underwater pouring device. Background Technology
[0002] Methods for underwater concrete pouring include: concrete pump pouring, tremie pipe method, flexible pipe method, caisson method, aggregate bag method, pouring method, and pre-filled aggregate grouting method. Among these, the concrete pump pouring method and the tremie pipe method are preferred because their equipment and construction are relatively simple, and quality is easily guaranteed. The tremie pipe method is suitable for underwater concrete pouring in water depths not exceeding 15–25 meters. The diameter of the tremie pipe is 25–30 cm, each section is 1–2 meters long, connected by flanges with rubber gaskets, and an automatic valve should be installed at the bottom, with a funnel at the top. The number and location of the tremie pipes should be determined based on the pouring area and the effective radius of the tremie pipes. Generally, the effective radius should not exceed 3 meters.
[0003] When using the tremie method for underwater concrete pouring, a crane is usually needed to lift the tremie pipe and funnel for pouring. However, this increases the demand for cranes. In addition, when connecting the tremie pipe and funnel together, they are usually connected by threaded fittings. Therefore, workers need to fix them very firmly during installation to prevent them from rotating and falling off. However, this makes disassembly more difficult.
[0004] Therefore, this application provides an underwater pouring device to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an underwater pouring device. When in use, the device, through the No. 1 support frame, can not only install and fix the guide pipe and funnel, reducing the crane's operating time, but also adjust the position of the guide pipe according to actual conditions to meet usage requirements. Furthermore, it can act as a safety railing to prevent workers from falling into the water, ensuring worker safety and safe construction.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an underwater grouting device, comprising a funnel, a support mechanism and a guide tube, wherein the support mechanism comprises a first support frame, a second support frame is slidably disposed inside the upper end of the first support frame, a third support frame is slidably disposed inside the second support frame, a first telescopic rod is fixedly disposed on one side of the upper end of the first support frame, and a second telescopic rod is fixedly disposed inside one side of the second support frame;
[0007] The conduit includes a second body, a support block is fixedly installed at the upper end of the second body, a fixing block is fixedly installed at the upper end of the support block, a connecting rod is rotatably installed inside the fixing block, and a fixing frame is fixedly installed at both ends of the connecting rod. One of the two fixing frames is threaded with a screw rod inside. The funnel includes a first body, and snap-fit blocks are fixedly installed on both sides of the lower end of the first body.
[0008] With the above technical solution, when using the device, the No. 1 telescopic rod pushes the No. 2 support frame, and the No. 2 telescopic rod pushes the No. 3 support frame. This facilitates adjusting the position of the conduit according to the actual situation. After the conduit is fixed, the No. 1 main body is placed inside the upper end of the No. 2 main body. After aligning the snap-fit block and the fixing block, the screw is turned by the handle. The screw passes through the groove at the upper end of the snap-fit block and is then fixed inside another fixing frame. This process is repeated to complete another set, thus completing the connection between the hole and the conduit. The connection process is relatively easy.
[0009] Furthermore, a storage frame is fixedly installed on one side of the first support frame, and a water-proof ball is installed inside the storage frame;
[0010] The above technical solution uses a water-resistant ball to slow down the descent of cement, preventing it from dispersing due to excessive speed.
[0011] Furthermore, a No. 1 pipe is fixedly installed inside the upper part of the No. 1 main body, and a plurality of small water outlet holes are opened at the lower end of the No. 1 pipe. A water pump is fixedly installed on one side of the No. 1 main body, and the water pump is connected to the No. 1 pipe. A No. 2 pipe is fixedly installed at the lower end of the water pump.
[0012] The above technical solution involves pumping water into Pipeline 1, which then discharges the water through multiple small holes. This process helps to wet the inner wall of the conduit, preventing the cement from sticking to the inner wall as it descends.
[0013] Furthermore, a handle is fixedly provided at one end of the screw, and two sets of the fixing block, connecting rod, two fixing brackets and screw are arranged in a mirror-symmetrical manner;
[0014] The above technical solutions help to make the connection more stable and prevent it from falling off.
[0015] Furthermore, the lower outer diameter of the first main body is equal to the inner diameter of the second main body, and the lower area of the snap-fit block is equal to the upper area of the fixing block.
[0016] The above technical solution facilitates easy docking between the first entity and the second entity, and provides support for the second entity.
[0017] Furthermore, a square groove is provided at the upper end of the third support frame, and a through hole is provided at the bottom of the square groove;
[0018] The above technical solution allows the No. 2 main body to pass through the No. 3 support frame while being fixed inside the No. 3 support block by the support block.
[0019] Furthermore, four support bases are fixedly installed at the lower end of the first support frame, and four brackets are fixedly installed at the upper end of the third support frame.
[0020] The above technical solution, with four support bases, helps to make the No. 1 support frame more stable and prevent it from sinking into the ground. The four brackets also help to further fix the funnel, reduce the pressure on the guide tube and the fixing block, and make it more stable.
[0021] This utility model has the following beneficial effects:
[0022] 1. The present invention proposes an underwater pouring device. When using the device, the first main body is placed inside the upper end of the second main body, the direction of the snap-fit block and the fixing block are aligned, and then the screw is passed through the groove of the snap-fit block. By rotating the screw with the handle, it is fixed in another fixing frame. The installation and disassembly process is relatively simple and saves physical strength. There is no need to worry about the funnel or guide tube rotating and falling off.
[0023] 2. The present invention proposes an underwater pouring device. When in use, the device pushes the second support frame through the first telescopic rod, and pushes the third support frame through the second telescopic rod. This facilitates the adjustment of the position of the second main body according to the actual situation. In addition, the first support frame can not only fix the funnel and the guide pipe, reducing the use time of the crane and eliminating the need for the crane to be constantly suspended, but also can serve as a handrail to prevent workers from falling into the water.
