Description

TECHNICAL DOUBLE PIPE APPARATUS FOR USING GEOTHERMAL ENERGY AND FOR GROUND REINFORCEMENT AND THE METHOD USING THE SAME}

The present invention relates to an integrated energy double pipe device and a method for reinforcing the ground while using geothermal energy, and more particularly, by installing an inner and an outer tube to reinforce the inside of the drilling hole, and passing the circulating water therein, It is not only easy to reinforce the ground structure, but also the utilization of geothermal energy and the reinforcement-integrated energy double pipe system and construction method that can effectively utilize the geothermal energy of the underground which maintains a constant temperature throughout the year. will be.

In general, the demand for geothermal energy continues to increase in line with the expanded supply of renewable energy.

Geothermal systems using such geothermal energy can be said to be very valuable in terms of developing new energy, but often have the problem of contaminating groundwater.

As an example of the prior art that can use the ground heat in the ground water is not collected in the state of the Republic of Korea Patent No. 10-0880675 "closed underground heat exchanger device and configuration method using a double insertion geothermal tube" has been proposed.

Such a conventional geothermal system is a structure using a double insertion geothermal tube as a closed underground heat exchanger.

The conventional technology is to insert a large diameter outer circulation tube shielding the lower end with a stopper in the excavation hole excavated in order to use geothermal heat, and then the inner circulation tube formed on the bottom of the inner circulation tube to the bottom It is inserted and configured.

In order to reduce the driving power cost, the closed circulation circuit is constructed to install the circulation pump on the ground, and the tip is conical to facilitate the installation of the external circulation pipe.

However, such a conventional technology focuses only on the acquisition of geothermal energy in the ground, and in order to use the geothermal heat, a circulation pipe is formed by connecting a hollow pipe made of PE material that has been weighted inside the geothermal drilling hole excavated deep in the underground rock. Geothermal heat is recovered through.

Therefore, there is a problem that does not play any role in reinforcing the ground for stabilization of the ground.

On the other hand as another conventional technology has been proposed "Geothermal pipe integrated ground reinforcement method" of Republic of Korea Patent No. 10-0778936.

This conventional technology prevents the ground from becoming weak when installing geothermal pipes, and reduces the cost of construction by installing pile anchors integrated with geothermal pipes that can secure both the use of alternative energy due to geothermal energy and the stability of structures. It relates to a geothermal pipe integrated ground reinforcement method can be obtained.

Charge in the hole. Then, the anchor pile is inserted onto the heat transfer grout, the packer is installed, and the cement grouting solution is supplied to the packer and then hardened.

In other words, such a conventional technique is constructed by dividing the tip section into the geothermal reinforcement section and the ground reinforcement section by the geothermal pipe integrated ground reinforcement method which can secure both the use of geothermal energy and the stability of the structure.

However, since the conventional technology is constructed by dividing the local acquisition section and the ground reinforcement section up and down, the depth of the ground perforation hole is formed relatively deep, resulting in an increase in the construction cost, thereby inefficient in terms of cost. .

On the other hand, ground structures such as tunnels, barriers, and slopes maintain a constant temperature throughout the year, so they are not suitable for use as actual geothermal energy resources.
