本発明は、鋼セルを用いた埋め立て地等の護岸
建設工法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a construction method for revetment of reclaimed land, etc. using steel cells.
（従来の技術）
埋め立て地等の護岸の急速施工工法としては、
一般にセル工法あるいはケーソン工法等が知られ

ていた。(Conventional technology) As a rapid construction method for revetment on reclaimed land, etc.
Generally, the cell method or caisson method is known. In this cell construction method, cylindrical steel cells are erected sequentially on the seabed and connected by arcs, and each steel cell and arc is filled with earth and sand to form a cell revetment. Here, this steel cell includes a steel plate cell formed into a cylindrical shape with one steel plate,
Alternatively, steel sheet pile cells, etc., which are made by connecting a large number of straight steel sheet piles together and assembling them into a cylinder, have been mainly used.
従来、この種の鋼セルを建設地点に立設する場

あつた（例えば、特開昭58−86206号）、特開昭58
−86207号等）。 Conventionally, when erecting this type of steel cell at a construction site, the steel cell was first built on land, then placed on a barge or hoisted by a large floating crane, transported to the construction site, and then erected. (For example, JP-A-58-86206), JP-A-58-86206
−86207, etc.)

増加するため、施工性と経済性の両面から限界が
あつた。(Problems to be solved by the invention) However, since this type of construction method uses floating cranes, etc., the costs involved are high, and in order to reduce this cost, the steel cells are floated on the sea and towed. Although methods have been proposed (for example, Japanese Patent Application Laid-Open No. 110724/1983), there is a limit to the depth of water that can be installed in the cell type. In other words, in order to cope with deep-water seawalls such as offshore artificial islands, it is necessary to increase the radius of the steel cells in order to obtain stability, but the radius is 10 m.
A large steel cell that exceeds the radius is unstable in shape and difficult to handle alone, and the force acting on the cell shell increases in proportion to the radius and water depth, making it difficult to construct and economically. There were limits on both sides.
本発明は、これらの点に着目してなされたもの

る。(Function) In the cell revetment construction method of the present invention,
A plurality of steel cells are erected and fixed at predetermined intervals on the upper surface of the steel shell of the base body in which an air chamber is formed by a high-strength membrane, and a pair of arcs placed opposite each other is used to connect each steel cell to each other. Because the structure is constructed by connecting each other, each cell reinforces the other, making it easy to handle steel cells that are relatively unstable when used alone.In addition, the base is sealed with a high-strength membrane. Since the air chamber acts as a float, it can be easily towed to the seawall construction site without using a large floating crane, etc. Here, the ballast inside the base is adjusted by water injection, etc., and the structure is constructed. By sinking a steel cell, placing filling material inside the base, and then filling the steel cell and arc with filling earth,
The aim is to construct a stable cell revetment that is easily adaptable to deep-water revetments and has excellent construction and economical efficiency.

For example, the size of the structure 1 is changed as appropriate depending on the depth of the sea area where the cell revetment is constructed and other environmental conditions.
The number of lines may also be determined according to the conditions. Also,
If it is a relatively small-scale device, the stiffener 17 for reinforcing the steel shell 11 can be omitted, and both ends of the opening of the steel shell 11 may be closed with steel plates and only the bottom surface may be closed. Furthermore, depending on the geology of the ocean floor, the cell revetment may be constructed directly on the ocean floor without constructing the mound 21. In addition, as the filling material 23 to be filled into the base body 3, if particularly strong strength is required, concrete with reinforcing bars may be used, and if so strong strength is not required, hardening agent, It is also possible to omit the mixing of additives and the like and use only earth and sand.

果が得られる。(Effects of the Invention) According to the construction method of the cell revetment of the present invention, a plurality of steel cells are erected and fixed at predetermined intervals on the upper surface of the steel shell of the base, and the steel cells are arranged oppositely to each other. Since the structure is constructed by connecting with a pair of arcs, each of them reinforces each other, and even steel cells, which are relatively unstable when used alone, become strong.
Even large steel cells with a radius exceeding 10 m, which would be difficult to handle if used alone, can be easily sunk, making it easier to construct deep-water seawalls. . Furthermore, in the present invention, a steel shell is made by bending a steel plate into a gutter shape and has a cross-sectional shape of a half oval shape with a flat top and an open bottom, and no steel plates are used for the bottom or both end faces of the steel shell. Since the steel shell is covered with a high-strength membrane and sealed to form an air chamber, which serves as the base, this base can be used as a float, without using a large floating crane, etc. The cell revetment can be towed to the revetment construction site at any time, and therefore, the cell revetment construction method is easy to construct and can be applied to deep water revetments, and is economically advantageous. Sometimes the base is filled with filler material, so even if it is a large steel cell, arc, etc. that is filled with filler earth and sand and becomes extremely heavy, it can easily support the weight. It will be done.
