Crash bearer and manufacturing method thereof
The invention discloses a crash bearer. The crash bearer comprises a crash bearer core and crash bearer guard boards. The crash bearer guard boards are fixed to the crash bearer core from the side faces of the crash bearer guard boards, wherein the crash bearer guard boards are made of active powder concrete. By the adoption of the crash bearer, in a connecting manner adopting expansion anchoring bolts and grouting liquid, an external corrosion source cannot invade an existing concrete crash bearer any more, and the service life of the existing crash bearer can be prolonged; and the crash bearer guard boards cannot be aged, construction is convenient and easy, and the maintenance cost is reduced. The crash bearer guard boards serve as face layer formworks, the concrete is poured directly, and the thickness and the quality of face layers are guaranteed; and the crash bearer guard boards and the crash bearer core are all made of a concrete material, the bonding performance is good, the use number of the formworks is decreased, and formwork detaching time is shortened. The invention further discloses a manufacturing method of the crash bearer.
