Description
Technical field
The present invention relates to a kind of safeguard structure, more particularly to a kind of safeguard structure and its construction method for highway.
Background technology
In recent years, with highway in China construction and the fast development of transport undertaking, road traffic accident and its number of casualties
Also increasing.Because former combined type guard bar design steel superstructure is ＂ strong column and weak beam ＂ forms, and crossbeam is met and hits identity distance from column
Meet hit side spacing it is smaller, crossbeam is weak in impact force directional stiffness, so as to cause motor bus collision guardrail after at column occur
Stumble resistance, influence travel safety.Meanwhile cross beam and upright post is unsatisfactory for collision energy requirement with the intensity that lower wall body structure is connected,
Motor bus is with after rail collision, the insufficient height of guardrail, causing motor bus to cross guardrail.With developing rapidly for vehicle, traveling
Vehicle has shown car miniaturization and this two poles of the earth situation of truck heavy-duty, old specification《Freeway traffic is pacified
Full facilities design and job specfication》（JTJ074-94）Requirement can not meet the needs of vehicle.
Patent " 201320792546.6 " discloses a kind of anticollision barrier for highway bridge, more particularly to a kind of highway
The reconstruction structure of bridge concrete guardrail, to have the wall of certain length, including former combination along bridge floor Longitudinal extending direction
Formula guardrail lower rebar concrete wall, the top of former combined type guard bar lower rebar concrete wall are provided with newly-increased concrete and protected
Column wall, increase newly and newly-increased reinforcing bar is provided with concrete guardrail wall, increase reinforcing bar and former combined type guard bar lower rebar concrete newly
Reinforcing bar in wall is connected.It transform existing combined type guard bar as concrete guardrail structure, makes full use of under original guardrail
The material of portion's wall body structure, reform strengthening cost is saved, improve the anti-collision level of guardrail, current friendship can be met again
It is logical to require；Although this design simplifies structure, its crashworthiness is bad, and height is not high, can not stop reverse distance light
The irradiation of lamp, adds potential safety hazard to a certain extent.
Patent " 201420518918.0 " discloses a kind of flexible freeway guardrail, including pedestal；Inserted on the pedestal
It is connected to column；Left guard rail and right guard rail are fixedly installed respectively at left and right sides of the column；It is solid on the left of the left guard rail
Surely it is connected with left support post；Right support post is fixedly connected with the right side of the right guard rail；It is fixedly connected on the left of the left guard rail
There is pivot pin seat；The pivot pin seat lower end has been made into integration pivot pin head；Pivot pin set is fixedly connected with the right side of the right guard rail；It is described
Pivot pin set middle part is provided through pivot pin through hole；Pivot pin head with being cascaded by way of pivot pin through hole grafting so that each
It is to be flexibly connected between guardrail, so that the guardrail of installation can be installed according to the radian of road curvature,
The stickiness of guardrail and highway both sides is ensure that, that is, does not interfere with the width of road, also ensure that traffic safety；This design
Although improving the pliability of guardrail, actual anticollision ability is not high, can not play a protective role well.
