Civil lattice wall construction

The present invention relates to a lattice wall structure for civil engineering, and particularly relates to a cofferdam structure constructed by using a ground material for a river bank revetment project and a ground material for solidification.

In recent years, there have been frequent floods in Taiwan, and the typhoon season has been continuously and severely damaged. The water related units are actively engaged in various water control and flood control measures. Because the mountainous situation in this province is steep and the geology is fragile, the concentrated heavy rain brought by the typhoon season often causes large-scale floods and earth-rock flows in the mountainous areas. Therefore, flood prevention is particularly important. In general, river remediation, most of which adopts a trapezoidal slope type gravity earth embankment, which is based on the water calculus to calculate the river channel width and the embankment height, and then the concrete is paved with the grade ingredients and the packing material; The hard embankments built in the river environment for decades are still difficult to resist the erosion of flexible flowing water. As long as the traditional embankment is destroyed by a single point of flooding, the internal grade ingredients are hollowed out, which often leads to more serious breakage.

A number of related literatures on "river remediation and embankment engineering" have been proposed, such as Taiwan Invention Patent No. 172062, which discloses a "deck construction method"; and, for example, Taiwanese new patent No. M304545, discloses a "river remediation" Another example is Taiwan's invention patent No. I290597, which discloses a "truss type space embankment, wall structure" and the like.

The main purpose of this creation is to provide a lattice wall structure for civil engineering, which is used to improve the shortcomings of the traditional dike that is hollowed out after the single point of the flood, causing a more serious breakage.

In order to achieve the above and other objects, according to the present invention, a lattice wall structure for civil engineering includes a cofferdam structure composed of an inner wall, an outer wall, a base plate and a top plate, and is internally filled with a backfill. Wherein the lateral surface of the dam structure comprises at least a pair of longitudinal structural walls spaced apart from each other between the inner wall and the outer wall; and, along the longitudinal plane of the dam structure, at a predetermined interval Most lateral structural walls form a majority of separate, closed lattice wall construction units.

According to the present invention, the interior of the cofferdam structure is vertically extended downward at the bottom end of the inner wall facing the river channel except that the majority of the longitudinal and lateral structural walls are separated into a plurality of closed lattice wall construction units to form a strong support structure. There is a basic retaining wall to block the river water scouring, and the base plate at the bottom extends an extension in the outer direction of the outer wall to make the foundation more stable and stronger. This is another purpose of the creation.

According to the creation, the inner wall, the outer wall, the basic plate, the top plate, the longitudinal structural wall and the horizontal structural wall, etc., are used for the earthwork, curing agent, cement, gray fly, water and additives for increasing fluidity, etc. After mixing, it is poured into the structural wall mold to solidify and form, and its strength is almost greater than that of traditional concrete. The earthwork comprises at least one of mud, sand and stone or a mixture thereof. Further, in the lattice wall structure unit inside the cofferdam structure, the earthwork, the curing agent, the cement, and the water which are locally taken from the river bank are stirred and used as a backfill, and solidified as if the concrete strength is condensed into one body. In this way, it is possible to prevent the embankment from being damaged by a single point of flooding, and then the interior is hollowed out to cause greater damage. This is another purpose of the creation.

The creation also provides a construction method of a lattice wall structure, which uses a steel as a wall skeleton, an outer layer with an expanded steel mesh as an outer mold, and a river bank. The cofferdam structure constructed by mixing the ground material and the solidified material without the need for demoulding, the method can reduce the amount of waste soil in addition to rapid construction.
