In order to extend the service life of bridges, we will introduce products that accurately grasp the damage and deterioration status of structures and perform appropriate repairs in a timely manner.
E-inspection コロコロeye
回転式打音点検器
It is a tool to detect abnormal parts inside concrete from the change in impact sound generated by moving and rotating a metal polyhedron against the concrete surface.
In the narrow space of girder end
Survey/diagnosis/repair technology
NSRV method
It is a construction method that enables visual confirmation of the narrow space between girder end spaces and investigation of the amount of salt in the girder, as well as repairs within a limited time.
Bridge extension device
Koyuma still water construction method
We have developed a small water stop construction method that allows water to be stopped in a narrow space.
Drain pipe free arm
(Bridge drainage pipe flexible mounting bracket)
It is a bridge drainage pipe flexible mounting bracket that does not require detailed distance measurement from the structure such as the bridge to the drainage pipe.
硬速コンクリート
（床版コンクリート補修用速硬
・高耐久断面修復材）
A repair material that is a set of premix type powder and special aggregate, and is ideal for partial repair of RC floor slabs.
E-construction S&SD drain
舗装浸透水排水装置
This is a new type of drain that has the function of draining the shoulder pavement headwater belt and draining the water between the pavement and the floor slab.
E-construction SPチェーン
エネルギー吸収型
チェーン式落橋防止装置
The plastic deformation of the slit steel pipe effectively absorbs the kinetic energy during a large-scale earthquake.
Bridge girder bottom repair technology
It is possible to hang the concrete in the narrow part of the girder end of the bridge upper part by the water jet method WJ(R) which digs into the narrow part of the minimum 12 cm.
Precast RC
Smart wall
A precast RC panel is installed as a formwork, and by filling the inside with grout mortar, it is integrated and realizes quick and cheap repair of concrete structures.
Bridge clearance repair technology
We have realized the inspection, diagnosis and repair of the bridge clearance (25 mm or more) of the RC hollow floor slab.
E-safely
高視認マルチ安全ベスト
(フルハーネス型対応)
高視認規格適合で夜間でも高い視認性で安全を確保。多用途のポケットを複数採用し、道具等の落下を防ぐ高所作業用途の設計
