Problems solved by technology

In this case, social vehicles entering the construction area will inevitably have an impact on construction personnel and construction machinery, resulting in serious safety hazards in the road sections near the construction area.
A typical situation is that social vehicles break into the construction area without paying attention to the construction signs, causing collision injuries to construction workers and construction vehicles
[0003] As disclosed in CN108756450A, a safety protection system for expressway construction discloses protective nets, columns, warning devices, etc. Although it has certain beneficial effects, it still has the following defects: dismounting and installation are not convenient enough, resulting in the system It is time-consuming to arrange in advance; in addition, the warning device needs electricity, and the power supply is not convenient enough when working in the field

Embodiment 1

[0021] see Figure 1~2 , in an embodiment of the present invention, a safety protection system for expressway construction includes several support columns 1 and folding guardrails 2 between adjacent support columns 1. Due to the foldable function of the folding guardrails 2, the The distance between the adjacent supporting columns 1 is adjustable, and it is very convenient when arranging the guardrails. It is not necessary to calculate the dimensions on site and then arrange them. The supporting columns 1 and the folding guardrails 2 are connected by a quick connection mechanism.

[0022] Specifically, the folding guardrail 2 includes a plurality of connecting rods I201 and connecting rods II202, wherein the connecting rods I201 are arranged vertically, and the inclined connecting rods II202 pass between two adjacent connecting rods I201. connected, and both ends of the connecting rod II202 are hinged to the connecting rod I201 through the pin shaft 204. In practical applicat...

Embodiment 2

[0026] see image 3 , in an embodiment of the present invention, a safety protection system for expressway construction, the quick connection mechanism includes a female plug connector 3 and a male plug connector 4 respectively located on the support column 1 and the folding guardrail 2, the female plug connector 3 and the The male plug connectors 4 are mated with each other, specifically:

[0027] The female plug joint 3 includes a locking sleeve 301, a socket pipe 303 and an extruded steel ball 306. The socket pipe 303 is fixed on the support column 1, and the outer sleeve of the socket pipe 303 is provided with a locking sleeve 301 that slides and fits with it, and the locking sleeve 301 is locked. A spring positioning ring 305 is fixed between the sleeve 301 and the outer wall of the socket pipe 303, and the outer sleeve of the socket pipe 303 is provided with a locking spring 302, and the two ends of the locking spring 302 are respectively connected to the spring position...

Abstract

The invention discloses a safety protection system for highway construction, relating to the technical field of highway construction. The safety protection system comprises a plurality of support columns and folding protective guards located between adjacent support columns, wherein the support columns are connected with the folding protective guard through quick connection mechanisms. The safetyprotection system has the beneficial effects that a distance between the adjacent support columns can be adjusted by the folding protective guards, the protective guards are arranged very conveniently, and on-site dimension calculation before the arrangement is not required; besides, the support columns are connected with the folding protective guards through the quick connection mechanisms conveniently and simply, which helps to improve the arrangement speed of the safety protection system.

Description

technical field [0001] The invention relates to the technical field of expressway construction, in particular to a safety protection system for expressway construction. Background technique [0002] With the increase of the operation time of the existing expressways in our country, various diseases are also constantly appearing, resulting in a continuous increase in the workload of road maintenance; moreover, with the development of the economy, the traffic capacity of some existing four-lane expressways can no longer meet the growing The need for traffic volume has led to a gradual increase in expressway reconstruction and expansion projects. This has led to an increase in highway construction areas. The expressway construction area usually needs to occupy part of the traffic lane and isolate the expressway construction area from the traffic lane through a temporary protective net. In this case, social vehicles entering the construction area will inevitably have an impact...
