BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water blocking sheet and its construction method in a waste disposal facility, and more particularly to a partition for connecting a circulating fluid supply / discharge pipe to a circulating fluid filling tank forming the water blocking sheet. The present invention relates to a water impervious sheet in a waste disposal facility that is simply and quickly constructed by upper and lower sheets attached to pipes and partition pipes, and its construction method.

2. Description of the Related Art In a waste disposal facility for landfilling industrial waste and general waste, a water shielding work should be performed on the bottom of the disposal facility so that leaked sewage from the disposal facility does not penetrate underground and cause environmental pollution. Mandatory to do.

[0003] In this water-blocking work, a method of laying a soft synthetic resin-based or rubber-based water-blocking sheet is adopted, but it occurs when the water-blocking sheet is not joined properly or during waste landfill work or after landfill completion. There was a risk that sewage from the defective part would leak to the outside due to damage to the water shielding sheet.

The cause of damage to the water-blocking sheet covers a wide range of physical and chemical damages and biological damages, and since it is difficult to completely prevent it, effective measures have not yet been established.

For this reason, a technique for detecting and repairing breakage of a sheet has been developed, and various detection methods have been proposed and put into practical use as a technique effective in terms of accuracy. With regard to, regarding indirect repair by injecting a chemical solution around the damaged part and excavating waste to directly repair the damaged part, even if the damaged part of the sheet is detected early, After the leachate has flowed out of the waste disposal facility, the restoration will be completed, and the environmental pollution that occurs during that time cannot be prevented. As for repairs, since the leaked part was repaired by injecting grout of cement etc., all of the injected space was solidified, and water leaked next in the solidified section. If had become a situation where the detection mechanism does not work.

[0006] In order to improve such a situation, the applicant of the present application, even if the composite water shield is damaged, repairs the damaged portion before the contaminated water flows to the outside and shields the water from the same section. We propose a self-repair type waste disposal facility that can be immediately repaired even if it is damaged again. (Japanese Patent Application No. 11-2
This application provides the self-repair type waste disposal facility 40 as shown in FIG. 11, and the waste disposal site 41 excavated in the shape of a depression and the waste disposal site 41 are provided close to the disposal site 41. It is composed of a management building 42 that is constructed.

In the waste disposal site 41, a water blocking sheet 43 which constitutes a water blocking mechanism is laid, and in a management ridge 42, a supply facility 44, a water feeding facility 45 and a water feeding facility 45 which constitute a supply management mechanism. A drainage facility 46 is provided. Administration building 42
Further, a control facility 47 that constitutes a control mechanism connected to each facility of the water blocking member and the supply management mechanism is also provided in the.

As for the relation between the respective mechanisms, as shown in FIG. 12, the water blocking mechanism 50 is constantly measured and monitored by the control mechanism 51, and its sound operation is maintained.
At the same time, the control mechanism 51 also measures and monitors the supply management mechanism 52, and confirms whether the quality of the liquid restoration material filled in the impermeable sheet is maintained in a normal state. When the water blocking sheet 43 of the water blocking mechanism 50 is damaged, the control mechanism 51 confirms this as a change in the liquid restoration material filled inside the water blocking sheet 43, and commands the supply management mechanism 52. To supply the liquid restoration material and support the self-repair of damage.

The completion of repair can be known by the decrease of the supply amount in the supply management mechanism 52 supplying the liquid repair material and the return to the overpressure state at the normal time.
Sound operation is restored.

The control mechanism 51 checks the progress status of damage repair in real time and manages the whole by measuring the data of the supply management mechanism 52 during this period. Since it does not require any external treatment, it is essentially unnecessary to confirm the damaged part. However, by attaching the detection mechanism 53 as shown in the figure, the damaged part of the water-impervious sheet can be identified and the damaged part can be identified. It is possible to make a display and contribute to the situation judgment.

In many waste disposal facilities, including the self-repair type waste disposal facilities described above, as the material of the water-blocking sheet, a water-blocking material made of synthetic rubber, soft synthetic resin or other polymeric material is used. In addition, layered water-blocking materials such as asphalt, rubber asphalt, and clay linings, or sheet-shaped water-blocking materials used for roofing are used.The water-blocking sheet is not a single sheet but is joined vertically and horizontally by multiple joints. Including a general example of a single-layer structure and a mechanism for detecting a defect, a double-layer lower-layer sheet is joined to multiple narrow-layer upper-layer sheets to form a double-layer water barrier sheet. Example (JP-A-2
-136414 gazette) is reported.

However, in the conventional reports,
In order to prevent sewage from leaking to the outside, regarding improper joining of the water blocking sheet during processing, damage to the water blocking sheet caused by external force during landfilling of waste or after completion of landfilling, It is a customary practice to detect the presence or absence of damage after the occurrence of the damage and to repair it, and it is good at the time of construction of the water-shielding sheet so that the imperfection of the water-impermeable sheet and the damage of the water-impermeable sheet do not occur. The water-blocking sheet and its construction, which are configured so that uneven pressure is not applied to the upper and lower sheets after laying the water-blocking sheet,
Was not considered.

Therefore, the colloidal liquid to be supplied and discharged can be permeated into the entire circulation liquid storage tank 9.

Therefore, the connection state of the supply / discharge pipe in the present invention is such that the connection portion in the circulating liquid storage tank is reduced to half of the usual case by providing the connection portion only at one place, and at the same time, the liquid supply liquid is supplied. Construction work of the laying board for burying the pipe and the drainage pipe is halved, and construction of the other laying boards as a mere concrete block is sufficient.

In addition, since the partition pipe is preliminarily processed and placed on the partition pipe, the work of arranging the pipe on site is omitted and the work amount of the laying board and the supply / discharge pipe is significantly reduced. This will greatly contribute to the reduction of construction cost and the construction period.
