The utility model discloses a solve the technical scheme that its technical problem adopted and be: the utility model provides a collapsible used drill way protector that recycles of bridge bored pile, including the fender section of thick bamboo that is located the drill way, the upper portion of protecting a section of thick bamboo is installed a set of guardrail stand along protecting a section of thick bamboo circumference evenly distributed, and the cylinder of guardrail stand is equipped with a set of iron chain hole from top to bottom, protects a section of thick bamboo top and is equipped with a set of iron chain from top to bottom, and the head end of every iron chain passes the iron chain hole that lies in same horizontal position department on the adjacent guardrail stand in proper order, forms closed annular protection chain with the chain ring swing joint of this iron chain.
The upper portion of protecting a section of thick bamboo and the lower part of guardrail stand are equipped with corresponding bolt hole respectively, and the guardrail stand is connected with protecting a section of thick bamboo through the fixing bolt with bolt hole complex.
The bolt holes at the lower part of the guardrail upright post are arranged in a matrix form.
The perimeter of each iron chain is larger than that of the protective cylinder.
The head end of the iron chain is provided with an iron chain hook, and the head end of the iron chain is movably connected with the chain ring through the iron chain hook.
The distance between two adjacent iron chains is not less than 40 cm.
The pile foundation steel pile casing is adopted as the casing.
The utility model discloses based on the beneficial effect that its technical scheme had lies in:
(1) the utility model provides a foldable and recyclable orifice protection device for a bridge bored pile, which changes the phenomena of easy deformation in turnover, high construction cost and the like of the traditional fixed guardrail and provides the foldable and recyclable orifice protection device for the bridge bored pile;
(2) the utility model provides a pair of methods such as orifice of a hole protector of collapsible recycling of bridge bored pile has changed combination form, mounting means of traditional rail guard to folding shrink detachable guardrail replaces fixed guardrail, has solved shortcomings such as traditional guardrail commonality is not strong, the utilization ratio is not high, has improved protecting effect and work efficiency by a wide margin.

Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Referring to fig. 1 to 5, the utility model provides a collapsible used cyclically drill way protector of bridge bored pile, including the section of thick bamboo that protects that is located the drill way, protect the upper portion of a section of thick bamboo and install a set of guardrail stand 1 that protects a section of thick bamboo circumference evenly distributed, the cylinder of guardrail stand is equipped with a set of iron chain hole from top to bottom, protects a section of thick bamboo top and is equipped with a set of iron chain 2 from top to bottom, and the head end of every iron chain passes the iron chain hole that is located same horizontal position department on the adjacent guardrail stand in proper order, forms closed annular protection chain with the chain ring swing joint of this iron chain.
The upper portion of protecting a section of thick bamboo and the lower part of guardrail stand are equipped with corresponding bolt hole respectively, and the guardrail stand is connected with protecting a section of thick bamboo through fixing bolt 4 with bolt hole complex. The bolt holes at the lower part of the guardrail upright post are arranged in a matrix form.
In the embodiment, the pile foundation steel casing 5 is adopted as the casing, four guardrail upright posts 1 with the same structure are arranged, and the guardrail upright posts 1 are made of 14I-shaped steel and are 1.2m long; an upper iron chain hole 1a of the upright post, a middle iron chain hole 1b of the upright post and a lower iron chain hole 1c of the upright post are respectively formed in the central position of the I-steel web plate of the guardrail 1, which is 5cm, 45cm and 85cm away from the top end, and the diameter of the iron chain hole is 3 cm.
