Abstract

PURPOSE:To provide a method effective for growing lawn grass on a golf course, a soccer ground or a racecourse and preventing freezing of a road. CONSTITUTION:A carbon face heating element A having width of >=1/5 inner area is made into an insulated waterproof structure and is built in the inside or the inside of walls of resin pipes 1a to Xa to be embedded in soil. The temperature in the inner space of the pipes is raised by heat stored by sending electricity and the temperature is regulated by a heat-sensitive sensor built in the space of the pipes to control the temperature of terrestrial heat by a command of a controller. Further a heat insulating material B is attached to the under surface of the pipes so as to generate heat effective for a rooting face and a gravel layer C is arranged between the pipes in a row to provide an execution method for exerting the temperature stored in the pipes on the gravel layer. A sand layer D and a fertilizer layer E are formed stepwise on the top of the pipes. A running cost and an initial cost can be saved by enlarging the intervals of the pipes to the maximum.

[Means for Solving the Problems] A structure that is buried in the ground 20 to 30 cm and considers mechanical load, water distribution, durability, energy saving, etc. has a cylindrical structure that can be connected and a uniform heat is applied to the ground surface. The method of bringing it is optimal. INDUSTRIAL APPLICABILITY According to the present invention, a carbon surface heating element is built in a long pipe to generate a muffled temperature (30 to 60 ° C.) in a cylindrical pipe, and further, the pipe muffled temperature is interlocked between parallel pipes to provide a pipe. It is a construction method that can effectively arrange the intervals between them and generate uniform heat on the ground surface. The length of the heat generating pipe is 50 to 10
Even if the length is 0M, there is no temperature unevenness, a surface heating element is built in each time the pipes are connected, and finally a method of centralized control with a temperature sensor makes installation extremely simple.

[Operation] A method of embedding heat-generating pipes in parallel, applying the pipe muddy temperature to the gravel layer between the parallel pipes, and then raising a uniform temperature on the ground surface, so that the space between the pipes can be maximized. Is. Therefore, the present invention can be said to be the most suitable method for the geothermal heat of a vast area, for example, a soccer field, a horse racetrack, a golf course, etc., which is more energy-saving than the ordinary method.

EXAMPLE FIG. 1 is a cross-sectional view of an embedded pipe heater.
An insulating and waterproof carbon surface heating sheet A is built in the resin cylindrical pipe 1a, and then the waterproof lid 2 is fixed. Further, one of the lids 2 is provided with a cylindrical pipe 5 and a hole 3 into which the temperature detecting sensor 4 can be inserted, and the pipe 5 is connected to a pipe 6 for protecting a sensing line. Further, in order to disperse the pipe temperature to an effective temperature for the rooting surface, the heat insulating material B is spread over the lower surface of the pipe 1a. FIG. 2 is an arrangement diagram in which pipe heaters are laid on a golf course, a soccer field, and the like. Pipe 1
The length of a to xa is 30 to 50 cm, which are arranged in parallel, and the length is 30 to 50 M. Furthermore, by connecting the pipes 5 and 6 containing the heat-sensitive wire, a construction that can be applied even in a large area can be obtained. Temperature sensor 4
Is a system that is controlled by the controller 7 and performs centralized control so that the muffled temperature does not become abnormal. FIG. 3 is a sectional view of the pipe arrangement. A gravel layer C is laid between the pipes 1a to xa. Furthermore, after laying a gravel layer D on the upper portions of the pipes 1a to xa, a fertilizer soil E is laid on the ground surface. This construction method is the most effective construction method in which the heat of muffled heat is pooled in the ground and then the heat is uniformly applied to the ground surface.

[0007]

The present invention is the most effective construction method in which a long heating pipe is buried in the ground and a uniform temperature is generated over the entire surface of the buried area. Unlike hot water pipes and hot air pipes, it has the advantage of generating even heat in long pipes, and because of its energy-saving structure, it achieves its purpose with 30% less energy than hot water pipes. It is the most epoch-making method because it is easy to install, has durability, and has complete temperature control.
