Embodiment 1

[0023] Such as Figure 1-3 As shown, a highway isolation pier 30 provided with a defense device provided by the present invention includes several pier bodies 20, and the pier bodies 20 are fixedly connected to each other through connecting bodies 10 arranged at both ends. Both sides of the pier body 20 or a The side is provided with several defense devices 40 facing the road driving direction. The defense devices 40 are circular or square structures. The defense devices 40 are arranged in rows and columns, and are fixed on the pier body 20. Each defense device 40 includes mutual The pressure plate 44, the detonation shell 48 and the explosive chamber 42 filled with high explosives 41 are sealed and fixedly connected. They are all made of hard plastic. The central position of the pressure plate 44 is provided with a striker chamber 47. The striker chamber 47 is provided with a striker 46 that can move downward. The spring 43 is provided with a detonator 49 for detonating the ...

Embodiment 2

[0029] This embodiment has been improved on the basis of Embodiment 1, and other structures are the same, and the difference is:

[0030] In this embodiment, in order to improve the impact force of the vehicle on the defense device 40, prevent the vehicle with small mass from detonating the defense device 40, and improve the impact strength of the defense device 40 when the vehicle hits, the hard plastic material There is a steel plate layer in the middle of the pressure plate 44. When the vehicle hits the pressure plate 44, the pressure plate 44 can bear a large impact force, so that the defense device 40 will not be hit when the pressure plate 44 is under a small pressure. Detonate.

Abstract

The invention belongs to the technical field of expressways, and particularly relates to an isolation pier with a defense device. The invention provides an expressway isolation pier with a defense device. The isolation pier comprises a plurality of pier bodies, and the pier bodies are fixedly connected with each other through connecting bodies arranged at the two ends. A plurality of defense devices facing a driving direction of a road are arranged on the two sides or one side of the pier body. The defense device comprises a pressing disc, a detonation shell and an explosive bin which are fixedly connected; a firing pin bin is arranged in the pressing disc, a firing pin is arranged in the firing pin bin, a disc spring is arranged in the detonation shell, a detonator for detonating high explosive is arranged on the lower side of the firing pin, a clamping head is arranged on the outer side of a detonator base on the lower side of the detonator, the clamping head is inserted into an external hanging base groove, and the external hanging base groove is fixedly formed in the pier body. In the invention, an impact force generated by a vehicle which impacts the isolation pier on the expressway can be reduced or offset, damage to the vehicle and personnel is reduced, a safety coefficient of driving is improved, and daily maintenance after installation is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of expressway maintenance, and in particular relates to an expressway isolation pier provided with defense devices. Background technique [0002] Such as figure 1 As shown, at present, many road sections of the expressway are equipped with a certain number of isolation piers (30) in the middle or on both sides of the road, and the isolation piers used are mostly made of reinforced concrete. The isolation piers (30) include the pier body (20) , the two ends of the pier body (20) are respectively provided with connecting bodies (10) for fixed connection with each other. With the passage of time and use, the isolation pier on the expressway will sometimes be hit by vehicles driving on the expressway, causing damage and injury to the vehicle and personnel, and will also cause damage and damage to the isolation pier to varying degrees. Affect the safety of the entire highway. Contents of the invention [000...
