Description
Technical field
Highway safety protection technology field is the utility model is related to, it particularly relates to which a kind of high-protection level protects temporarily
Column.
Background technology
With the rapid growth of China's economy and flourishing for highway transportation cause, the volume of traffic increases rapidly, and highway is handed over
The frequency of use and load of logical facility also sharply increase, and the highway much built in early days can not adapt to current traffic
The operation demand of amount, according to incompletely statistics, in the highway built before 2004, about 30,000 kilometers have been enter into and change
Extension stage.At present, take the mode while constructing of runing mostly for highway extension project mode, temporary guard rail into
In order to protect the important means of construction area.The temporary guard rail that uses at this stage it is most of it is convenient for disassembly and assembly on, but crashworthiness is
Deficiency, it is impossible to effective protection is formed to construction area, so construction area also when have the accident that vehicle is swarmed into, and be all often car
Ruin the serious accident that people dies；Part temporary guard rail has certain anticollision ability, but removed after installing it is complex, in construction area
Scene often directly carries out destructive dismounting, and not reproducible utilization, causes substantial amounts of waste of material.In conclusion reorganization and expansion is applied
Work area needs one kind both to have preferable crashworthiness, while facilitates temporary guard rail of the installing and dismounting so as to recycling.
According to crashworthiness requirement and easy disassembly functional requirement of the reorganization and expansion construction area to temporary guard rail, propose a kind of high
Degree of protection temporary guard rail.
The content of the invention
The purpose of this utility model is to provide a kind of high-protection level temporary guard rail.To overcome current construction area temporary guard rail
The deficiency of protective capacities and property convenient for disassembly and assembly.To realize above-mentioned technical purpose, the technical solution of the utility model is realized in
's：
A kind of high-protection level temporary guard rail, including precast concrete wall, connection structure, the precast concrete wall
By on internal reinforcing bar casting concrete material be made, the connection structure is arranged on precast concrete wall both ends, multiple
Realize that longitudinally connected is entirety by connection structure between precast concrete wall, the connection structure is bolt pattern, I-shaped
One kind in steel form, the bolt pattern for connection bolt in mounting groove through two connecting holes it is longitudinally connected often save it is prefabricated
Concrete wall, the I-steel form are inserted into corresponding link slot realization for i shaped steel both ends and often save pre-cast concrete walling
Body connects, and the precast concrete wall both sides Ying Zhuan faces are in single slope surface form, F type slope surfaces form, reinforced slope surface form
One kind.
Further, the bolt pattern includes pre-buried steel member and connection bolt, and the pre-buried steel member includes installation
Groove, connecting hole, the pre-buried steel member and internal reinforcement welding, are embedded in precast concrete wall both ends, two section concretes
The connecting hole alignment of pre-buried steel member on cob wall body.
Further, the pre-buried steel member or passes through polylith by setting connecting hole to be made on rectangular tube or channel steel
Steel plate is welded into flute profile and sets connecting hole to be made.
Further, the I-steel form includes i shaped steel and link slot, the link slot according to i shaped steel
Matched shape and size are arranged on precast concrete wall both ends.
After adopting the above technical scheme, the utility model has following beneficial effect：
（1）Be easy for installation and removal function, is conducive to road construction；
（2）Concrete wall has preferable crashworthiness, and preferable protection can be formed to construction area.
