Abstract
The construction method includes making one or several pairs of holes in the road separating line and in the place to form opening, and inserting railing into the holes. The railing consists of two corrugated steel sheets and two uprights. Normally, the railings are inserted into the holes for isolation and protection, and the corrugated steel sheets with excellent anti-collision performance and energy absorbing performance make the railing endurable and protective. In case of altering the lanes for road repair, the railing may be removed easily to open passage.
Description
Technical field
The present invention relates to a kind of highway barrier, relate in particular to a kind of highway median opening place and isolate the job practices of establishing, also relate to a kind of special-purpose guardrail of this job practices simultaneously.
Background technology
In the highway construction, often be provided with an opening at a certain distance on the highway median strip, under the normal condition, these opening parts are often sealed with certain facility, it need be removed when meeting special circumstances.At present, it is comparatively heavy that the isolation facility at highway median opening place has, and very inconvenient when needs are mobile, labour intensity is big; What the isolation facility that has adopted is telescopic barrier, though its profile novelty is insecure, when being subjected to clashing into, both damages easily, does not reach the purpose of security protection again; Adopt steel pipe weldering system to form in addition, though this structure is firm, not only heaviness but also not attractive in appearance; Simultaneously, when bumping, do not have energy and the buffering effect of absorbing, bigger to vehicle and driver and conductor's harm.
Summary of the invention
At the problems referred to above, the object of the present invention is to provide the isolation job practices at a kind of highway median opening place.
Simultaneously, the present invention also aims to provide the dedicated set mould assembly guardrail of the isolation job practices at a kind of highway median opening place, the effect of attractive in appearance to take into account, light and effective protection.
For achieving the above object, technical program of the present invention lies in adopting the isolation job practices at a kind of highway median opening place, vertical line of symmetry of dividing strip opening part is provided with a pair or more of column plug hole, and the plug hole is used for inserting wears the column guardrail.
Described plug hole is realized by following steps: (1) gets out earlier pore on the ground; (2) in pore, put into the sleeve pipe of internal diameter greater than the fence upright diameter; (3) pouring into a mould concrete in the space of sleeve pipe periphery gets final product.
Described sleeve pipe can be steel pipe or pvc pipe.
Described movable rail reaches two root posts that fixedly fold up between the two by two waveform steel guard rail plates and constitutes, two root post geometrical clamps are contained between two waveform steel guard rail plates, two waveform steel guard rail plates respectively the link by separately with back to mode be fixed on two fence uprights, at waveform steel guard rail plate two ends the guardrail rounded head is installed also.
Simultaneously, technical program of the present invention also lies in providing the dedicated set mould assembly guardrail of the isolation job practices at a kind of highway median opening place, this guardrail reaches two root posts that fixedly fold up between the two by two waveform steel guard rail plates and constitutes, and two root post geometrical clamps are contained between two waveform steel guard rail plates.
Described two waveform steel guard rail plates respectively the link by separately with back to mode be fixed on the column.
Two ends at waveform steel guard rail plate also are equipped with the guardrail rounded head.
Method of the present invention is to be provided with earlier a pair or more of column plug hole on vertical line of symmetry of dividing strip opening part at a certain distance, special-purpose guardrail is installed in every pair of plug hole, two waveform steel guard rail plates respectively the link by separately with back to mode be fixed on two pluggable fence uprights, when highway is normally operated, guardrail utilization plug column can insert in the plug hole that opening part sets in advance easily, plays and isolates and protective action; Simultaneously and the guardrail band on outside the highway echo mutually, uniform, attractive in appearance supporting.When vehicle collides it,, both be not easy to be smashed, can have played a very good protection to vehicle and driver and conductor again simultaneously because waveform steel guard rail plate has good crashworthiness performance and endergonic effect.When pavement maintenance or other reason need and lead to, can be easily the guardrail of respectively organizing of opening part be extracted and removed, open up passage, be convenient to vehicle pass-through.The present invention is simple in structure, and is reasonable in design, plugs lightly, and good popularization and application prospect is arranged.
Description of drawings
Fig. 1 is the structural representation of guardrail of the present invention;
Fig. 2 is the vertical view of guardrail.
The specific embodiment
The isolation job practices at highway median opening of the present invention place is as follows: four columns plug hole is set on vertical line of symmetry of dividing strip opening part, the plug hole is used for inserting wears the column guardrail, this guardrail reaches two root posts 1 that fixedly fold up between the two by two waveform steel guard rail plates 2 and constitutes, two root posts, 1 geometrical clamp is contained between two waveform steel guard rail plates 2, two waveform steel guard rail plates 2 respectively the link 3 by separately with back to mode be fixed on the column 1, at the two ends of two waveform steel guard rail plates 2 guardrail rounded head 4 is installed all also and (sees Fig. 1, Fig. 2), insert in advance in the plug hole that opening part is provided with the assembling back.Wherein plugging the hole is realized by following steps: (1) gets out earlier pore 5 on the ground; (2) in pore 5, put into sleeve pipe 6; (3) pouring into a mould concrete in the space of sleeve pipe 6 peripheries gets final product.Sleeve pipe 6 is a pvc pipe, also can be steel pipe.
During use, four pairs of fence uprights 1 are set on vertical line of symmetry of isolation strip opening part, every pair of fence upright is equipped with two waveform steel guard rail plates 2, the length of every waveform steel guard rail plate 2 is generally 2.0m, and light weight is convenient to move, when pavement maintenance or other reason need and lead to, can remove the guardrail of respectively organizing of opening part easily, open up passage, be convenient to vehicle pass-through.In use, each is organized between the movable rail and can also interconnect by chain cable, to reach the purpose of antitheft and mutual reinforcing.
