Description

The structure to increase the efficiency of the prevention structure liquid chemical method

The present invention relates to a structure for improving the efficiency of the prevention structure liquid chemical method, in particular, it uses the floating lift of the floating ball, which can effectively dissipate the resistance generated by the buoyancy of the ground water during the insertion, and enhance the water collection and drainage effects.

The so-called soil liquefaction is the transformation of soil from a solid state to a liquid state. The sandy soil particles in the stratum are small and the pores between the particles are smaller. Although the pores are connected, the flow of water is slow. Under the pressure of seismic waves, the pore water cannot be discharged immediately to reduce the pressure, and "excess pore water pressure" is formed in the pores. When the sum of the pore water pressure exceeds the confining pressure of the soil, the friction force of the soil disappears due to the viscous force of the sand. It is originally small, so the instantaneous shear strength is close to zero, and the soil can be deformed indefinitely under the force to become a liquid mortar, which is called soil liquefaction.

At present, various structures are often tested by the water in the stratum below their base. Once the water content of the stratum reaches an over-saturated level, if the water cannot be discharged quickly, disasters such as weak foundation and collapse of the base may occur at any time.

Many areas with soil liquefaction potential nowadays have the "sandy soil" in the "high groundwater level" in their strata. When they are shaken by an earthquake, an "excess pore water pressure" is formed, causing sandy particles to float in the water. , So that the sandy soil loses its ability to carry the weight of the building Therefore, before constructing various structures in the potential area of soil liquefaction, it is necessary to carry out stratum improvement works, such as installing suppression devices to prevent soil liquefaction (Soil Liquefaction), which will prevent earthquakes. Dissipation and elimination of excess pore water pressure can prevent damage caused by liquefaction during earthquakes.

The following two kinds of suppression devices are currently common to prevent soil liquefaction (Soil Liquefaction), and their disadvantages are at least as follows:

1. Vertical drainage belt: easy to block, high engineering cost.

2. Gravel sand pile: high cost and time-consuming construction.

In addition to the above-mentioned shortcomings, when all the soil liquefaction prevention devices are inserted into the ground surface, their bottom ends will encounter strong resistance generated by the buoyancy of the ground surface water. Therefore, one of the conventional technologies has a soil liquefaction prevention device which is more effective A movable flap is set at the bottom opening by a hinge (Hinge) to form a movable valve. The groundwater opens the movable valve with its water buoyancy to enter the device to dissipate the resistance generated by the buoyancy of the ground water when it is inserted. The movable valve will be closed to achieve the purpose of water collection, but these structures still have the disadvantages of being more complicated, easily damaged, and increasing the manufacturing cost.

In addition, the inventor previously applied for Taiwan Patent No. M526591 "Capillary Permeable Drainage Pipe Adapter". The adapter includes an adapter body for socketing on the capillary permeable drain pipe, which can be passed through the adapter tube. The body is connected to another capillary permeable drainage pipe or a general pipe body, so that the liquid drawn by the capillary permeable drainage pipe through capillary action can circulate through the adapter pipe body.

When the adapter of the aforementioned patent is inserted into the ground surface after the capillary permeable drainage pipe is sleeved, because the bottom end is closed, it will also encounter strong resistance generated by the buoyancy of the ground surface, which is not conducive to the installation operation.

From the above, it can be seen that how to dissipate the resistance generated by the buoyancy of the ground surface when the soil liquefaction suppression device is inserted in order to facilitate the installation and improve the water collection and drainage effects is a major issue in the industry.

It is that the inventor of the present invention is based on the idea of innovation, based on years of professional experience in product development in this technical field, as well as active research and development thinking, and through countless actual design experiments, the invention has been produced.

The purpose of the present invention is to provide a structure that can effectively dissipate the resistance generated by the buoyancy of the ground water during the insertion, and improve the water collection and drainage effects so as to prevent the structure from improving the efficiency of the structure liquid chemical method.

To achieve the above objective, the present invention includes a ball tube with a continuous hole, a ball hole, and a stop hole in the ball tube. The ball hole is provided with a floating ball whose outer diameter is larger than the straight The hole and the hole where the ball hole is connected, the stop hole is provided with a stop rod, the stop rod is used to limit the floating ball to only move in the ball hole, and the stop hole is used to connect with a The transfer pipe is connected to a drain pipe.

When the bulb is inserted under the ground surface, the groundwater can push the floating ball away and flow in through the fully open orifice, thereby effectively dissipating the resistance generated by the buoyancy of the ground water when it is inserted, which facilitates installation and improves water collection and drainage effects , When the ball tube reaches the position, due to the internal and external balance of the groundwater pressure, the ball will naturally fall on the orifice to cover and close the orifice.

The invention is set up around the ground surface of the structure in the highly liquefied stratum, and applies the impact force of the groundwater pressure at the moment of floating and confluence discharge, such as collecting groundwater produced by earthquakes, to avoid liquefaction.
