Abstract

(57) [Summary] (Correction) [Purpose] When constructing shade concrete for steel sheet pile wall heads, precast concrete is used to reduce site work and shorten the process. [Structure] A cap concrete block 1 having a fixed length having an open lower surface for accommodating the head of the steel sheet pile wall 4 and a concrete inlet on the upper surface is continuously installed and mounted, and is mounted inside the cap concrete block. After welding the adjustment metal fitting 3 and the steel sheet pile, the bottom plate 1 is set, concrete is poured from the upper part, and if necessary, the concrete casting port 7 has the same surface finish as the shade concrete block 1 precast concrete plate 2 Insert and embed. Also, by using the shade concrete block 1'where only one of the both sides is removed and only the reinforcing bar 16 is exposed, it is possible to cope with a location where the thickness of the steel sheet pile wall exceeds the open portion 6 due to construction error or curved construction. And

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention reduces the work on site by using precast concrete in the construction of the cap concrete for the steel sheet pile wall head installed in the revetment work in a river, and immediately starts the next process without waiting for the curing of the in-place concrete. At the same time, it is possible to eliminate the process at the construction site by preliminarily applying a surface finish that matches the surrounding landscape at the factory.

[0002]

[Prior art]

 Conventionally, the cap sheet concrete of the steel sheet pile wall is constructed by forming a formwork at the site, providing the necessary reinforcement, and then pouring the concrete into the site.In recent years, the finished surface has been patterned according to the surrounding landscape. Although it is sometimes colored, it is done on site after the curing and hardening of concrete.

[0003]

[Problems to be solved by the device]

 With conventional technology, all construction is done on-site, so temporary construction work is required for deadline drainage and formwork assembly, and it is difficult to ensure a uniform finish for surface treatment after concrete hardening. However, there was a problem that the unevenness in the quality of This invention eliminates the need for deadline drainage and formwork assembling on-site, and enables immediate progress to the next process without waiting for the curing and curing of concrete, and at the same time even when patterns and coloring are applied to the surface. It is intended to enable various finishes.

[0004]

[Means for Solving the Problems]

 This invention uses a precast concrete block of a certain length that has an upper part with a concrete inlet on the top and both sides, and the lower part is open so that the head part of the steel sheet pile wall can be stored sufficiently. , The height and horizontal position were fixed by adjusting metal fittings installed inside the cap concrete block, which were continuously installed corresponding to the extension of the sheet pile wall. Set the bottom plate and pour concrete from the top. If necessary, a precast concrete board with the same surface finish as the cap concrete block is fitted to the concrete input port on the top surface so that the top surface is the same surface, to obtain cap concrete. When a part of the steel sheet pile wall is curved or construction error causes insufficient opening between both sides of the concrete block, one side is removed to expose only the reinforcing bar. Using blocks together, a backing plate is applied to the outside of the exposed reinforcing bars, and concrete is poured from the top surface to obtain continuous shade concrete.

[0005]

[Action]

 Since the present invention has taken the above-mentioned means, on-site formwork and rebar assembly can be omitted, which eliminates the need for water replacement work and scaffolding work by preliminary temporary deadline. In addition, the finishing metal fittings on the inside of the shade concrete block adjust the position of the finished top and side surfaces of the shade concrete, and at the same time, they are welded and integrated with the steel sheet pile wall, so that the filling of the solid concrete from the top is stable. It is possible to do so, and it is possible to move to the next process such as backfilling of back soil and revetment of revetment blocks even before the curing of the placed concrete. Then, if necessary, insert a precast concrete plate finished on the same surface as the cap concrete block into the concrete inlet on the top of the cap concrete block to anchor it to the filled concrete and make it flush with the top surface of the cap concrete block. By doing so, it is possible to easily obtain a landscape pattern shade concrete with a special surface treatment. Furthermore, when the shade concrete block was continuously installed on the head of the steel sheet pile wall, the opening between the two sides of the shade concrete block was insufficient due to the curved construction of the steel sheet pile wall and a construction error, and the steel sheet pile wall head was opened at the open portion. Even in areas where parts cannot be stored, one side of both sides is removed to use only a concrete block that exposes only the reinforcing bars, and the side where the side has been removed is installed facing the back soil side. Can be constructed.

【Example】

 The embodiments shown in the drawings will be described in more detail below.

As shown in FIGS. 1 to 7, after applying the foundation material (10) to the back surface, the cap concrete block (1) is placed so that the head of the steel sheet pile wall (4) is housed in the open portion (6). It is continuously installed by the crane, the position is adjusted by the slit (15) of the adjustment metal fitting (3), and it is fixed by the vault (8), and then the continuous concrete concrete blocks (1), (1) are joined to each other by the vault (9). ), And at the same time, the adjustment metal fitting (3) and the steel sheet pile wall (4) are welded to temporarily integrate the wall body and the cap concrete.

After that, the bottom plate (11) is tentatively fastened with a vise fastener (12), and the solid concrete (5) is poured from the concrete inlet (7) on the upper surface of the shade concrete block (1). However, it is possible to backfill the back soil (13) and slope work even before the solidified concrete (5) is hardened or even before it is placed.

Then, if necessary, a precast concrete plate (2) is used, and fitting and embedding is performed by using an anchor (14) on the concrete inlet (7) on the upper surface of the shade concrete block (1) so that the surfaces are flush with each other. By doing so, the construction of shade concrete is completed, but by applying patterns and coloring on the surface after finishing it from the factory production stage, on-site work can be omitted and a uniform finish is possible. Become.

Further, by removing one of the side portions and using a shade concrete block (1 ′) in which only the reinforcing bars (16) are exposed, a backing plate (17) is applied and the filled concrete (5) is poured. As a result, curved construction of steel sheet pile walls and construction errors are large, and it is possible to install at locations that do not enter the open part (6), making it possible to construct continuous shade concrete.

[0011]

[Effect of device]

 The present invention is based on such a configuration, which eliminates the need for temporary cutoff water replacement work and scaffolding work at the site, omits formwork and rebar assembly, and does not wait for the curing of the medium-filled concrete for the next process. It has become possible to save labor and speed up construction work, and by embedding a precast concrete plate with the same surface finish as the shade concrete block in the upper opening. It is possible to easily and surely obtain a shaded concrete with a landscape pattern by omitting the surface processing work in the field. Even in places where the steel sheet pile wall cannot be stored in the open part of the shade concrete block due to curving due to curved construction and large construction error, one of the side parts is removed to expose only the reinforcing bar to the shade concrete block. By using it, it is possible to continuously construct steel sheet pile wall concrete with precast concrete.
