TW202122663A - Structure for preventing structure body from liquefaction capable of effectively dissipating the resistance generated by the buoyancy of the water under the ground surface during insertion of the pipe - Google Patents

Abstract

Provided is a structure for preventing structure body from liquefaction, which comprises: a ball pipe equipped with a straight hole, a ball hole and a stopper hole in a connected state, wherein a floating ball is installed in the ball hole, and the outer diameter of the floating ball is larger than that of the straight hole and the opening where the ball hole is connected. The stopper hole is provided with a stopper bar with which the floating ball is restricted to movement only in the ball hole, and therefore the stopper hole is used to combine an adapter tube for being connected to a drainage pipe. When the ball pipe is inserted downward into the ground surface, the groundwater can push away the floating ball and flow through the opening that is completely opened, so as to effectively dissipate the resistance generated by the buoyancy of the water under the ground surface during insertion thereby facilitating the installation and improving the water collection and drainage effect. When the ball pipe reaches its position, the ball body will naturally fall on the opening due to the internal and external balance of groundwater pressure, so as to block and close the opening. In the present invention, the structure object is installed below the ground surface perimeter of high liquefaction strata to avoid the occurrence of liquefaction by applying the floating and convergent discharge of instantaneous groundwater pressure impact, such as collecting groundwater generated by earthquakes.

Description

Structure to prevent liquefaction of structure

The present invention relates to a structure for preventing liquefaction of structures, in particular to the use of floating balls to lift and lower, which can effectively dissipate the resistance generated by the buoyancy of the ground water during insertion, and improve 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.

In many areas with potential for soil liquefaction, there is a "sandy soil" in the "high groundwater level" in the strata. When an earthquake shakes, 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. The 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 provided at the bottom opening by a hinge (Hinge) to form a movable valve. Groundwater uses its water buoyancy to open the movable valve and 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 collecting water, 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 the siphon principle can circulate through the adapter pipe body.

When the adapter of the above-mentioned patent is inserted into the ground surface after the capillary permeable drainage pipe is sleeved, because the bottom end is closed, it will 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 water when the soil liquefaction suppression device is inserted in order to facilitate installation and improve the water collection and drainage effects is a major issue in the industry.

It is that the inventor is based on the idea of innovation, based on years of professional experience in product development in this technical field, and active research and development thinking, and through countless actual design experiments, the invention was born.

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 when the floating ball is used for floating, and improve the water collection and drainage effects to prevent the structure from liquefying.

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 hole. 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 communicate 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 arranged around the ground surface of the structure in the high liquefaction stratum, and applies the impact force of the groundwater pressure at the moment of floating and confluence discharge, such as collecting groundwater generated by earthquakes, to avoid the occurrence of liquefaction.
