Abstract
The present invention discloses a road anti-collision protecting fence height-increasing construction method, and said method is characterized by that in the condition of no moving original length-fixed anti-collision protecting fence post a lengthened sleeve can be added and mounted on the top of the original length-fixed anti-collision protecting fence post, then on the lengthened sleeve the anti-collision fence can be fixed so as to implement said invention.
Description
Technical field
The present invention relates to a kind of construction of the highway method, relate in particular to a kind of highway anti-collision guardrail heightening construction method.
Background technology
The highway both sides generally will install anticollision barrier additional, in case motor vehicles are gone out the road surface when meeting accident and caused pernicious traffic accident, therefore, anticollision barrier has certain requirement apart from the height on road surface.But every time through about 10 years of highway pavement repairs always and about bed hedgehopping 10cm, makes anticollision barrier constantly reduce apart from pavement-height, thereby does not reach the requirement of relevant specification.For this reason, existing solution is that original anticollision barrier column is completely extracted roadbed, unified moves certain position, punches on roadbed again, plants to adorn new lengthening column or original column shallow embedding is solved, and the while must the original old Kong of landfill.Make time-consuming in this way taking a lot of work, also damage roadbed, the application life of having reduced highway easily simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of highway anti-collision guardrail heightening construction method.
In order to achieve the above object, technical program of the present invention lies in adopting a kind of highway anti-collision guardrail heightening construction method, this method is by under the situation of not moving original fixed length anticollision barrier column, install the lengthening sleeve pipe additional at original fixed length anticollision barrier column top, and then on the lengthening sleeve pipe fixedly the step of anticollision barrier realize.
Because the method applied in the present invention is: under the situation of not moving original fixed length anticollision barrier column, install the lengthening sleeve pipe additional at original fixed length anticollision barrier column top, and then on the lengthening sleeve pipe fixedly the step of anticollision barrier realize.This just makes anticollision barrier to be increased on the basis of not moving original column, has saved opening old hole on roadbed, filling old hole and plant again the dress column process, can save a large amount of operating expenses; Do not destroy simultaneously the original structure of roadbed, improved the efficiency of construction of increasing guardrail the application life that helps to improve highway yet, have important social benefit and economic benefit.
Description of drawings
Fig. 1 is the highway anti-collision guardrail assembling schematic diagram before increasing;
Fig. 2 is the highway anti-collision guardrail assembling schematic diagram after increasing.
The specific embodiment
As shown in Figure 1 and Figure 2.Among Fig. 1, anticollision barrier 3 is by in the fixing hole 2 that is bolted to column 1 top.During construction, earlier the anticollision barrier on the column shown in Fig. 113 is pulled down, the sleeve pipe 4 that will extend then is sleeved on the top (as shown in Figure 2) of column 1, and by bolt lengthening sleeve pipe 4 and column 1 is tightened together, at last again anticollision barrier 3 by be bolted to the lengthening sleeve pipe 4 on.Lengthening sleeve pipe 4 is provided with two mutual parallel radial direction through hole 5,6 one on the other, and both are at a distance of about 110cm.During installation, fixing hole original on lengthening lower through-hole 6 of sleeve pipe 4 and the column 12 is aimed at, penetrated will extend sleeve pipe 4 and column 1 of bolt again and be fixed together.At last, anticollision barrier 3 is fixed by bolts in the last through hole 5 of lengthening sleeve pipe 4.
Claims (1)
1, a kind of highway anti-collision guardrail heightening construction method, it is characterized in that: this method is by under the situation of not moving original fixed length anticollision barrier column, install the lengthening sleeve pipe additional at original fixed length anticollision barrier column top, and then on the lengthening sleeve pipe fixedly the step of anticollision barrier realize.
