The present invention relates to a chamber for positive pressure damping treatment and a construction method thereof, and in particular, a chamber for positive pressure damping treatment for treating groundwater flowing into a foundation floor before the installation of discarded concrete after completion of the final digging work for building construction. It is about a construction method.

In general, the permanent drainage method forms a drainage path at the bottom of the bottom layer where excavation is completed as a method of releasing the positive pressure on the underground structure. It is a construction method to stabilize the structure.

Permanent drainage method as described above is divided into MPC method (Minimum Pipe & Clogging Drainage System), installation method using a partial drainage and double-sided plate drainage, shear surface gravel laying method and drain mat drainage method.

Here, the MPC method is a method for minimizing the concern about the construction cost due to the clogging phenomenon and the excessive drainage ditches, which is an existing problem, and guarantees the quality and the air with the maximum stability and the minimum construction cost. There is a problem that requires hydraulic modeling and repair, geotechnical design.

In addition, the installation method using the partial drainage and the double-sided plate drainage is a drainage method for collecting gravel in the drainage channel of several places under the mat foundation to collect groundwater induced by the drain board through the gravel layer and the bundle pipe, and the installation position is rock work. In this case, not only is there an excessive cost in drainage ditches, but there is a problem that accurate modeling, repair, and geotechnical design by soil experts are required as in the MPC method.

In addition, the shear surface gravel laying method is a drainage method of collecting gravel laying and collecting bundles in the gravel laying layer and the gravel layer on the shear surface of the finish surface under the mat foundation after the final excavation is completed. The burden is generated, the cost is increased, the earthwork volume is increased compared to the partial trench method, the air is increased, the geotextiles should be installed on the shear surface to prevent foreign substances, and the aggregates are exhausted due to the collection of aggregates. There is a problem that the amount of earthwork increases.

Finally, the drain mat drainage method is a drainage method that collects a part of the drainage channel under the mat foundation through a flat drain board and a bundle pipe integrated in excavation and discarded concrete. When the construction surface is rock, the cost of surface treatment is increased. It is excessively generated, and it is not only complicated to manage the process due to the connection between the circular bundle tube, the rectangular bundle tube, and the flat drainage, but also lacks the integrity between these structures. It is difficult to apply to, and there is a problem in the structural stability due to the washing function and the inability to secure the cross-sectional area.

That is, the conventional permanent drainage methods for solving the conventional positive pressure as described above, in addition to the basic disadvantages of each method, the mechanism or apparatus that can accurately calculate and calculate the magnitude of the positive pressure acting on the foundation floor as a whole Since there is no separate provision, there is a problem in that the site has to reprocess the positive pressure acting on the building structure in the future by assuming the magnitude of the positive pressure or simply treating it based on construction experience.

Thus, the present invention was devised to solve the problems as described above, for the positive pressure attenuation treatment for easily treating the groundwater flowing into the foundation floor before the installation of the discarded concrete after completion of the final trench construction for the construction structure construction The object is to provide a chamber and a construction method thereof.
