Problems solved by technology

[0002] Municipal roads and bridges are the arteries and hubs of urban traffic in my country. With the development of cities, not only many new roads need to be built, but more importantly, existing roads need to be updated with the needs of urban development. The isolation of existing roads The update of safety guardrails is very important. The existing road guardrail update methods include new bases and columns to install guardrails, steel bases and columns to install steel guardrails, and one-time arrangement of concrete without bases. Guardrails (without interchangeability and multiple use), all of which have a common disadvantage, the installation is cumbersome, and the cost is high, mostly for one-time use

Embodiment Construction

[0031] The technical solutions of the present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0032] Such as figure 1 and Figure 7 As shown, a continuous prefabricated safety guardrail connection method described in the present invention,

[0033] Include the following steps:

[0034] 1) Lay out the line at the position where the guardrail needs to be installed as the starting position;

[0035] 2) Hoist the section N guardrail 1 to the starting position first;

[0036] 3) Put the nut assembly on the two ends of the double-ended screw rod 3 respectively, and insert one end into the embedded part 7 of the guardrail embedded in the guardrail 1 of the Nth section;

[0037] 4) Fix the end of the double-ended screw mandrel 3 in the guardrail embedded part 7 on the Nth section guardrail 1 through the screw mandrel pin 6;

[0038] 5) Appropriately tighten the nut assembly at the end of guardrail 1 of Section N, but not too tigh...

Abstract

The invention relates to the technical field of added fences for existing roads and bridges, in particular to a continuous prefabricated safety fence connecting method. The continuous prefabricated safety fence connecting method has the advantages that the geometric sizes of existing prefabricated fences are not changed, and existing safety specification requirements can be assuredly met by use effects of new fences; connection modes of the continuous prefabricated safety fence connecting method are mechanical connection modes for various units of the prefabricated fences by the aid of double-end lead screws, the units of the prefabricated fences of various sections can be organically connected with one another, accordingly, protection effects which are equally effective just like protection effects of existing fences can be realized, and merits of detachability and interchangeability of mechanical connection and connection firmness and reliability can be sufficiently embodied; more importantly, pavement destruction for manufacturing bases and mounting upright rods is omitted, characteristics of protection reliability, mounting convenience, detaching convenience, universality and interchangeability and reusability can be truly embodied, and accordingly the continuous prefabricated safety fence connecting method has a certain economic benefit and a high social benefit and is worthy of being popularized.

Description

technical field [0001] The invention relates to the technical field of new guardrails for existing roads and bridges, in particular to a method for connecting continuous prefabricated safety guardrails. Background technique [0002] Municipal roads and bridges are the arteries and hubs of urban traffic in my country. With the development of cities, not only many new roads need to be built, but more importantly, existing roads need to be updated with the needs of urban development. The isolation of existing roads The update of safety guardrails is very important. The existing road guardrail update methods include new bases and columns to install guardrails, steel bases and columns to install steel guardrails, and one-time arrangement of concrete without bases. Guardrail (does not possess interchangeable and multiple use), all these all have a common shortcoming, and installation is loaded down with trivial details, and cost is high, is disposable use mostly.
