Description

Drainage system for soft ground using open channel and water-permeable drainage member}

The present invention relates to a soft ground collection and drainage system formed by dredging, etc. More specifically, a plurality of water permeability in the upper, lower and vertical directions in a single or a plurality of channels having a permeable upper filter material coated on the top By forming three-dimensional arrangement of drainage material in the horizontal and vertical directions, it is possible to display the surface water and the pore water including the rainwater generated in the upper part of the soft ground while showing excellent collection and drainage function of the soft ground soil gap. Excellent ground drainage performance can be obtained in the top and deep layers, and in particular, the soft ground drainage system using a water channel and permeable drainage can bring about efficiency and economic efficiency of the ground drainage system of the soft ground improvement construction and ease of construction.

The dredged rough ground is in a sludge state, has a high compressibility, and has little ground strength.

Such dredged landfills should have a minimum bearing capacity to secure the runability of heavy equipment put into the soft ground improvement work, which requires at least several months to several decades after dredging landfill.

However, the method of securing longevity through the neglecting period is due to the problem of construction period and the occurrence of group complaints of residents around dredging landfills due to the habitat of pests during the neglecting period. Development is needed.

Therefore, as a method for securing the drainage and durability of the soft ground mainly employed in the soft ground improvement work, it is left for a long time after dredging and forms a horizontal drainage layer made of reinforcing materials such as geotextiles and sand or gravel. The method of draining the pore water by inserting the vertical drainage material into the ground is mainly used.However, this method is soft for a long time in order to secure the required bearing capacity of the soft ground due to the delayed drainage of the gap water generated during the soft ground improvement. Ground improvement work should be carried out.

Accordingly, the applicant of the present invention proposed a channel in which the drainage is formed in the cross direction in the bottom of the channel formed in the continuous longitudinal direction as in Patent Registration No. 1019882 and applied to the soft ground surface treatment method.

However, in the construction of the soft ground drainage using the channel, the drainage is formed on the bottom of the channel in the plane, which is excellent as the surface treatment method of the soft ground, but the drainage system is the soft ground. Because it is installed in the surface of the soft soil, including the rainwater coming down from the upper fill part, and the drainage performance of the pore water rising through the channel or the upper part of the soft ground through the vertical drainage material is not effective Occurred.

In addition, since the horizontal drainage layer made of gravel or sand should be formed on the upper part of the channel, there is a problem of an increase in construction cost and troublesome construction.

The present invention has been made in order to solve the above problems, to form a water-permeable drainage in a plurality of horizontal directions in the cross direction of the upper and lower parts in a single or a plurality of the number is coated with a permeable upper filter material on the top, By connecting or draining the vertical drainage to the upper drainage, the water drainage performance of the soft ground can be improved by the three-dimensional drainage structure, and the surface water and the pore water including the rainwater generated in the upper part of the soft ground are treated. In particular, the present invention provides a soft ground drainage system using a water channel and a permeable drainage material, which can reduce construction costs by replacing the horizontal drainage layer made of gravel or sand. It is an object of the invention.

Specific means for achieving the above object, the main drainage means is constructed in the ground of the soft ground and one or more of the number of drainage of the rainwater and gap water of the ground or ground to the catchment and the catchment of both ends;

An upper drainage means formed of at least one of an upper drainage means for draining the rainwater and the gap water of the ground or the ground into the catchment and the drainage channel in a manner of interviewing or penetration in a direction intersecting with the channel in the upper part of the channel;

A lower drainage means formed of at least one lower drainage material formed at a lower portion of the channel by an interview or penetration in a direction intersecting with the channel and for draining the lower gap water in the ground into the catchment and the channel; And

It can be achieved by including a vertical drainage means of the vertical drainage for collecting and draining the ground water of the ground on both sides of the channel.

The soft ground collection and drainage system using the water passage and the permeable drainage of the present invention as described above, the surface water and the gap water including the rainwater of the upper and lower parts of the soft ground at the same time through the upper and lower drainage and vertical drainage By quickly collecting water into the furnace, it is possible to obtain an effect that can significantly improve the performance of water collection and treatment of water generated at the surface, ceiling, and deep layers during soft ground improvement construction.

In addition, by replacing the horizontal drainage layer forming the filling part by the conventional gravel or sand formed on the upper part of the soft ground and the waterway, the collection and drainage system is used to reduce the construction cost by securing the quick and easy collection and drainage performance in the soft ground improvement construction. It is possible to obtain an effect that can lead to a drastic shortening of the construction period by securing early endurance.
