Embodiment 1

[0078] This embodiment provides an anti-collision pier, including an anti-collision pier core and an anti-collision pier shield; The side is fixed on the core of the anti-collision pier; wherein, the anti-collision pier shield is made of active powder concrete; of course, in this embodiment, the anti-collision pier shield can also be one piece, when the anti-collision pier When the bumper shield is one piece, it is fixed on the bumper core from one side, such as the left side, of the bumper core.

[0079] In this embodiment, optionally, a reinforced anti-crack net is arranged inside the anti-collision pier guard plate, and the reinforced anti-crack net is arranged along the length direction of the anti-collision pier guard plate; The mesh improves the strength of the anti-collision pier shield; and preferably, the reinforced anti-crack mesh is glass fiber mesh cloth, carbon fiber mesh cloth or steel wire mesh.

[0080] In this embodiment, the anti-collision pier protective pl...

Embodiment 2

[0085] refer to Figure 1-3 , the present embodiment provides a preparation method of the anti-collision pier using the repaired anti-collision pier guard plate, which includes two parts, namely preparing the anti-collision pier guard plate and installing the anti-collision pier guard plate on the anti-collision pier core body; the steps of preparing the repaired anti-collision pier shield may include the following two types:

[0086] The first method: perfusion method

[0087] S10, apply a release agent on the surface of the outer mold and the core mold that is in contact with the active powder concrete, and close the molds;

[0088] S20, put the material for preparing active powder concrete into a forced mixer, stir to make a uniform slurry, pour it into the mold prepared in step S10, place the anti-collision pier guard plate after the mold loading on the vibrating table, and vibrate Stop when there is no obvious bubble overflow and no bleeding;

[0089] S30, curing the s...

Embodiment 3

[0105] refer to Figure 4-6, this embodiment provides a method for preparing an anti-collision pier using a formwork-type anti-collision pier guard plate, which can be used as a road anti-collision pier and can be moved, but the number is small, and active powder concrete materials need to be used on both sides. Prefabrication in the factory, which includes two major parts, that is, the preparation of the anti-collision pier shield and the formation of the anti-collision pier core inside the anti-collision pier shield; the steps of preparing the formwork type anti-collision pier shield can include the following two types:

[0106] The first method: perfusion method

[0107] S10, apply a release agent on the surface of the outer mold and the core mold that is in contact with the active powder concrete, and close the molds;

[0108] S20, put the material for preparing active powder concrete into a forced mixer, stir to make a uniform slurry, pour it into the mold prepared in st...

Abstract

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.

Description

technical field [0001] The invention relates to a building structure, in particular to an anti-collision pier and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy and the increase of investment in infrastructure construction, the mileage of expressways such as expressways and urban viaducts in my country has achieved a milestone breakthrough in recent years, but the safety problems caused by high-speed driving have become more and more prominent. , due to the high speed of the vehicle, the severity of the accident is relatively high, causing a large number of casualties and property losses. [0003] In order to reduce the severity of accidents, various highway management departments have strengthened highway management, increased road monitoring, and improved traffic safety facilities. Among them, the anti-collision pier is an important safety facility, which can absorb vehicle collision energy and make the vehicle...
