Construction method of retractable steel trestle guardrail device
The invention relates to bridge construction, in particular to a construction method of a retractable steel trestle guardrail device. Comprising the following steps that A, a steel trestle is constructed; step B, guardrail manufacturing; c, end bases and a middle base are manufactured; d, end bases and a middle base are installed; e, the end vertical rod of the guardrail is inserted into one inserting groove of the end base, and the middle vertical rod is inserted into the middle base; f, a clamping groove is formed in the steel bridge deck; g, the guardrail is laid flat, the buckles are placed in the clamping grooves in the steel bridge deck, then the whole guardrail is moved outwards, the buckles and the clamping grooves are hooked and clamped firmly, and the end vertical rods are in threaded connection with the tongue plates; and H, the water level falls back, and the guardrails on the two sides are recovered. The guardrail and the steel trestle are of an assembly type structure, are convenient to assemble and disassemble and can be repeatedly used; when water rises in the flood season, only the guardrail needs to be put down and fixed to the steel bridge deck through the buckles, the guardrail is prevented from being detached, carried back and forth and damaged, cost is reduced, and work efficiency is improved.
本发明涉及桥梁施工，特别是一种可收放的钢栈桥护栏装置的施工方法。包括如下步骤：步骤A、钢栈桥施工；步骤B、护栏制作；步骤C、制作端底座和中间底座；步骤D、端底座和中间底座安装；步骤E、将护栏的端立杆插装在端底座的一个插槽内，中间立杆插装在中间底座上；步骤F、钢桥面板开设卡槽；步骤G护栏放平，将卡扣放入钢桥面板上的卡槽内，再将护栏整体外移，卡扣与卡槽钩卡牢固，端立杆与舌板螺接；步骤H、水位回落，将两侧护栏恢复。本发明的护栏与钢栈桥为装配式结构，安拆方便，可重复使用；汛期涨水时，只需将护栏放倒并通过卡扣与钢桥面板固定即可，避免了护栏的拆除、来回搬运和毁损，既降低了成本，又提高了工效。
