Description

TECHNICAL FIELD

[0001] The utility model relates to a rock-soil body water releasing device. BACKGROUND

[0002] The main role of the rock-soil body water releasing is that there is pore water pressure in the rock-soil body, when the pore water pressure is too high, the effective stress of the rock-soil body will be reduced, according to the effective stress principle (effective stress is equal to total stress minus pore water pressure), the reduction of the effective stress will reduce the shear strength of the rock-soil body, resulting in the stability of the rock-soil body to decline, water releasing can make the pore water discharge, reduce the pore water pressure, so as to improve the effective stress of the rock-soil body, for example, in a saturated clay slope, due to the rain and other reasons, the pore water pressure increases. If water releasing is carried out by setting drainage facilities, the pore water pressure is reduced, so the stability of the clay slope will be enhanced, because the effective stress is increased, the anti-sliding force is also increased, and when the underground water contains some corrosive components (such as sulfate, chloride ion, etc.), chemical erosion will be caused to the rock-soil body, continuous water releasing can reduce the underground water level in the rock-soil body, reduce the contact time and contact area of the underground water and the rock-soil body, so as to reduce the probability of erosion, for example, for some rock-soil body containing gypsum and other soluble salts, when the underground water is in long-term contact with the rock-soil body, the soluble salt will dissolve, resulting in the destruction of the rock-soil body structure, by reducing the underground water level through water releasing, the degree of chemical erosion can be reduced.

[0012] Compared with the prior art, the utility model has the beneficial effects as follows:

[0013] 1. The utility model passes through the accumulated water inside the rock and soil body or when the groundwater is higher than the position of the drain pipe, the water flows into the drain pipe through the hole under the action of gravity, and then flows out to the outside through the guide pipe, the outlet pipe, and the rotating piece. When the water accumulated inside the rock and soil body is too much, the drainage volume increases. When the accumulated water flows to the position of the outlet pipe through the guide pipe, the water flow first contacts the fixed piece due to the height difference, and is then guided to the position of the water wheel by the fixed piece. The accumulated water drives the water wheel to rotate, and the water wheel drives the drive shaft and the gear to rotate, and the gear drives the tooth plate to move downward, and the tooth plate drives the drive block and the guide rod to move downward and squeeze the spring. At the same time, the drive block drives the connecting piece, the round rod, and the rotating piece to rotate with the connection between the connecting piece and the round rod as the center. As the water flow increases, the impact force of the water flow on the water wheel increases, and the tooth plate and the guide rod squeeze the spring. The squeezing force of the spring is increased, thereby driving the rotating piece to gradually increase the opening and closing angle. When the water flow decreases, the squeezing force on the spring begins to decrease, and the spring pushes the guide rod, tooth plate, etc. to reset, and the rotating piece begins to close, so that a small water flow is discharged through the water flow hole on the rotating piece. This solves the problem that when draining water from rock and soil, different drainage flow rates are required due to different environmental conditions. For example, when the water volume of the rock and soil increases, the valve can be opened to increase the drainage volume, thereby avoiding landslide and collapse of the rock and soil due to excessive water accumulation. On the contrary, when the water content of the rock and soil is low, the valve can be appropriately closed to maintain a certain groundwater level to prevent excessive drainage from causing cracks in the rock and soil. The valve adjustment operation of the current device mostly relies on manual labor, which makes the drainage of the rock and soil more inconvenient and reduces the drainage efficiency of the rock and soil. It has the advantage of being easy to adjust.

[0014] 2. The utility model is provided with a driving mechanism, which can increase the drainage volume when there is too much water accumulated inside the rock and soil body. When the accumulated water flows to the position of the outlet pipe through the guide pipe, the water flow first contacts the fixed plate due to the height difference, and is then guided to the position of the water wheel by the fixed plate. The accumulated water drives the water wheel to rotate, and the water wheel drives the drive shaft and gear to rotate. The gear drives the tooth plate to move downward, so that the tooth plate drives the drive block and the guide rod to move downward, thereby improving the driving effect of the adjustment mechanism.
