The present invention relates to an underground floor drainage construction method for inducing and draining groundwater penetrating from the lower part of a building to a water collecting well, and in particular, in forming a drainage path by connecting a drain board (drainboard) or a bundle pipe on a cast concrete. It relates to a basement floor drainage construction method for forming a drainage path by directly connecting the main drainage member or the secondary drainage member to the sump well so that the groundwater is smoothly drained while blocking the inflow of soil.

In general, when a large building or a building is newly constructed, the construction of the underground structure is essential, and deep excavation is performed when the construction is performed. Therefore, the dead weight (self-weight) of the building is applied to the floor of the basement, and at the same time the floor There is an uplift pressure due to groundwater (uplift pressure) acts, at this time, if the upstream pressure is greater than the dead weight, the building rises may cause deformation, such as the floor, walls of the building.

Therefore, there is a need for an appropriate drainage construction to reduce the upward water pressure acting on the bottom surface of the basement layer and to drain the groundwater penetrating from the bottom surface of the basement layer.

As a general construction method for reducing the upward pressure acting on the bottom surface of the basement layer anchors anchored in the lower rock layer of the underground structure to resist upward hydraulic pressure by dead weight and permanent anchor (permanent anchor) The drainage method is mainly applied to form a drainage path on the bottom surface of the gulto finish surface and to continuously drain the water well to reduce the water level of the groundwater to suppress the upward water pressure acting on the bottom surface of the basement layer.

First, the anchoring method is perforated to the rock layer, and after inserting the strand in the perforated portion is constructed by the process of tensioning and fixing more than the required load, the construction cost for each process is expensive, and after construction, let waterproof to the perforated portion There are a lot of occurrence is difficult to repair this, and a high technology and a number of processes are required to anchor the anchor construction period is also delayed at least one month or more than the drainage method of forming a drainage on the bottom of the basement layer, the anchor method There are few domestic construction companies that can solve the technical problems required for tension loss, rust prevention, and maintenance. In addition, when constructing a re-tensioning system to compensate for the loss of tensile strength of the anchor, there is a problem that the construction cost takes two to three times or more than when construction.

On the other hand, in the drainage method, a drainage plate or a bundle pipe is widely used as a means for forming a drainage path under the concrete concrete forming the basement floor of a building, and the drainage path induces groundwater penetrating from the basement floor for water resistance. It is installed by intersecting the drainage plate or the bundle tube between the gulto finish surface and the discarded concrete to be treated by fertilization, and connecting the end of the drainage channel adjacent to the sump to the sump, and then pouring concrete concrete. .

However, in the conventional underground floor drainage method, a bundle pipe acting as a drainage channel is buried in a trench, and a drain plate is installed to be adjacent to the outer circumferential surface of the bundle pipe, filling the trench with gravel, and casting concrete and concrete concrete. Because of this, the construction period according to the trench formation is long, and because the S-type plastic bar is wrapped in the fiber state in the bundle state by the geosynthetic fiber, high water pressure was required to flow the groundwater. In addition, the groundwater induced by the drainage plate is filtered by the geosynthetic fibers wrapped on the outer circumferential surface of the bundle pipe and is introduced into the bundle pipe. When the groundwater is introduced together with the soil, a clogging phenomenon occurs in the geotextile and the groundwater. The water collection function of the can not be carried out by the multi-chamber collection or drainage function as a result of the upward pressure is applied to the basement floor of the building, groundwater can penetrate the bottom surface of the basement floor.

As described above, the connector for the wastewater treatment structure of Utility Model Registration No. 314875, which is designed and applied by the applicant of the present application in order to solve the problem caused by not being directly connected to the bundle pipe and the drain plate, is a socket such as a cylinder or a square tube. Is formed in the form, the connector is formed with at least two connectors for interconnecting the bundle tube or the drain plate, the connector is made of the upper case and the lower case is separated or assembled, the upper case or the lower case with an insertion groove and At least one insertion protrusion is formed, and the bundle pipe connected to the drainage structure connector and connected to the sump is securely connected to the drainage plate to form a drainage path, so that drainage is formed without forming a trench as in the prior art. Construction was possible.

However, in the drainage construction method using the connector for the drainage structure, the groundwater absorbed by the drainage plate is collected only through the bundle pipe connected to the sump. The pipes alone cannot be processed smoothly, and eventually upward pressure is applied to the bottom of the basement, which can deform the structure or penetrate the groundwater. Therefore, in order to solve this problem, a drainage path must be formed to properly collect and drain the groundwater guided to the drainage plate, while minimizing the flow resistance of the drainage path connected to the sump when the groundwater is dispersed and collected. It is necessary to form a drainage path through which smooth drainage can be made.

In order to solve this problem, there is an invention filed by the present applicant (Application No. 10-2004-00038330).

To provide a basement floor drainage construction method to form a drainage path Respectively.

However, the present invention, if the groundwater drainage reinforcement construction for the atmospheric pressure after the casting concrete is placed during the construction of the building, it is necessary to remove the discarded concrete and then construct the drainage system, which may cause unexpected construction periods and costs. There was a problem in that it was not possible to adequately respond to sudden drainage system construction requirements after casting abandoned concrete.

In addition, the conventional drainage system induces groundwater directly through the collecting pipe to the sump at the same depth as the underground depth of the system drainage, so that the groundwater where the pressure from the ground to the depth between the sump and the system drainage acts. There was a problem that can only be processed.
