Description

Technical Field

[0001] The present application relates to the field of anti-seepage wall combined cofferdam, and in particular to a high-pressure rotary jet grouting pile anti-seepage wall combined cofferdam. Background Art

[0002] In water conservancy and hydropower projects, in order to provide dry working conditions for construction within the cofferdam, it is necessary to first build the cofferdam water retaining structure. In order to reduce the amount of water seepage in the cofferdam and the safety of cofferdam seepage, it is necessary to build an anti-seepage structure inside the cofferdam.

[0003] The existing anti-seepage structures mainly include soil anti-seepage bodies, concrete anti-seepage bodies, high-pressure rotary jet pile anti-seepage bodies, and geomembrane anti-seepage bodies.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that general water retaining structures need to be provided with troughs for draining water later. However, the current practical drain troughs generally need to be manually blocked after use. However, manually blocked drain troughs generally take a long time, and manual blocking may also cause leakage later.

[0005] Therefore, it is necessary to invent a high-pressure rotary jet grouting pile anti-seepage wall combined cofferdam to solve the above problems. Utility Model Content

[0006] The purpose of the present application is to solve the problems raised in the above-mentioned background technology, and to provide a high-pressure rotary jet grouting pile anti-seepage wall combined cofferdam.

[0007] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0008] A high-pressure rotary jet pile anti-seepage wall combined cofferdam comprises filling soil, a first anti-seepage component is arranged inside the filling soil, a second anti-seepage component is arranged outside the filling soil, a support component is arranged on the top of the filling soil, a transmission component is arranged on the top of the support component, a connection component is arranged inside the support component, and a water discharge component is arranged at the bottom of the support component.

[0009] By adopting the above technical solution, the water discharge component is driven by the transmission component to operate, thereby completing the water discharge and blocking.

[0010] Furthermore, the first anti-seepage component includes two high-pressure spraying anti-seepage walls fixedly connected to the inside of the filling soil, and the two high-pressure spraying anti-seepage walls are arranged opposite to each other.

[0011] By adopting the above technical solution and using high-pressure spraying to build an anti-seepage wall, the possibility of water leakage can be reduced.

[0012] Furthermore, the second anti-seepage component includes a plurality of sandbags fixedly connected to the outside of the filling soil, the plurality of sandbags are divided into six groups, the six groups of sandbags are stepped, and composite geomembranes are fixedly connected to the outside of the six groups of sandbags.

[0013] By adopting the above technical solution, a variety of anti-seepage layers can be provided through the combination of sandbags and composite geomembranes, thereby reducing the occurrence of water leakage.

[0014] Furthermore, the support assembly includes two support plates fixedly connected to the top of the filling soil, and a top plate is fixedly connected to the top of the support plates.

[0015] By adopting the above technical solution, through the cooperation of the support plate and the top plate, the water discharge assembly can be lifted up, thereby facilitating water discharge and water blocking.

[0016] Furthermore, the transmission assembly includes a transmission rod rotatably connected to the top of the top plate, the top of the transmission rod is fixedly connected to a motor, a first pulley is provided on the outer fixed sleeve of the transmission rod, a belt is rotatably connected to the outer side of the first pulley, and the inner end of the belt is rotatably connected to a second pulley.

[0017] Furthermore, the transmission assembly also includes a threaded sleeve fixedly sleeved inside the second pulley, the threaded sleeve is rotatably connected to the top plate, a lifting rod is threadedly connected inside the top plate, and the lifting rod passes through the top plate and is slidably connected to the top plate.

[0018] By adopting the above technical solution, the transmission rod is driven to rotate by the motor, thereby driving the belt to rotate, thereby driving the threaded sleeve to rotate, thereby driving the lifting rod to rise, thereby driving the water discharge assembly to rise and fall.

[0019] Furthermore, the drainage assembly includes a drainage trough opened inside the filling soil, sandbags and top plate, a blocking block is slidably connected inside the drainage trough, and the blocking block is fixedly connected to the lifting rod.

[0020] By adopting the above technical solution, through the cooperation of the drain trough and the blocking block, water draining and water blocking can be carried out more conveniently.

[0021] Furthermore, the connection assembly includes two support rods fixedly connected to the bottom of the top plate, the two support rods are arranged on both sides of the bottom of the top plate, and the support rods penetrate the blocking block and are slidably connected to the blocking block.

[0022] By adopting the above technical solution, the blocking block is supported by the support rod, thereby improving the stability of the blocking block when it moves.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In the present application, the motor is started to drive the transmission rod to rotate, thereby driving the first pulley to rotate, thereby transmitting power to the second pulley through the belt, thereby transmitting power to the threaded sleeve, thereby driving the lifting rod to rise, thereby driving the blocking block to rise, thereby completing the water discharge. When the drain tank needs to be blocked, the motor can be started to reverse, thereby driving the blocking block to move downward, thereby blocking the drain tank, thereby completing the water blockage.

[0025] 2. In the present application, the pressure of water is transmitted through sandbags. The pressure borne by the sandbags will be transmitted to the filling soil, and then the pressure will be transmitted to the high-pressure injection anti-seepage wall, so as to release the pressure multiple times, thereby increasing the service life of the device. After the water pressure is transmitted, the water will contact the composite geomembrane. At this time, the composite geomembrane will block the water, so that the water will not enter the sandbag. When the first layer of the composite geomembrane is damaged, the water will be blocked by the second layer, thereby reducing the possibility of water contacting the filling soil.
