Embodiment 1

[0022] A method to improve road safety on the river ice surface by adding structures. Before the river water surface freezes, select waters with no clear ditch after natural freezing in winter, uniform ice thickness, and ice thickness ≥ 30cm as the water area across the river. The temporary road paving area on the ice surface; the network structure 2 is pre-laid underwater in the paving area, and the width of the network structure is 3 to 5 times the width of the temporary road on the ice surface. The network structure 2 It is not affected by low temperature and has a good combination with ice; according to the average thickness of ice in the water area where the laying area is located, the mesh structure 2 is fixed in the ice layer 3 at a position two-thirds away from the ice surface, so The two ends of the mesh structure 2 are respectively fixed on the fixed piles 5 arranged on both banks. After the ice layer with a thickness ≥ 30 cm is formed on the water surface of the rive...

Embodiment 3

[0028] A method to improve road safety on the river ice surface by adding structures. Before the river water surface freezes, select waters with no clear ditch after natural freezing in winter, uniform ice thickness, and ice thickness ≥ 30cm as the water area across the river. Temporary road paving area on the ice surface; pre-laid network structure 2 underwater in the paving area, the width of the network structure is 3 to 5 times the width of the temporary road on the ice surface, and the network structure is Nylon mesh or steel cable mesh, in which the nylon mesh is made of 8 strands of 35mm diameter ship cables, the mesh size is 60~90cm×60~90cm, and the steel cable mesh is made of 6×19+FC9mm oiled steel wire rope. The mesh size is 60-90cm×60-90cm; the mesh structure 2 is not affected by low temperature, and has a good degree of integration with ice; The object 2 is fixed in the ice layer 3 at two-thirds of the distance from the ice surface, and the two ends of the mesh str...

Abstract

The invention relates to a method for enhancing the safety of a river ice surface temporary road by additionally mounting a structure and belongs to the technical field of road traffic. In order to solve a problem that the river ice surface has a potential safety hazard as the temporary road, the invention provides the method for enhancing the safety of the river ice surface temporary road by additionally mounting the structure. Before icing, a net-shaped structure is pre-laid underwater, the net-shaped structure is fixed in a position, having 2 / 3 distance from the ice surface, in an ice layer, the two ends of the net-shaped structure are fixedly arranged on fixing piles on both shores, and the ice surface in the middle position above the net-shaped structure is the safe ice surface temporary road after the water surface is iced to form the ice surface. According to the method for enhancing the safety of the river ice surface temporary road by additionally mounting the structure, by additionally arranging the net-shaped structure in an ice body, the strength and bearing ability of the ice body are improved; the bearing ability of the ice body reaches 5KG / cm2 or above; the safety ofthe ice surface as the temporary road is enhanced; the safeties of passing vehicles and pedestrians are guaranteed; and a problem that traffic jams in cities are caused during using bridges in winters is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of road traffic, and in particular relates to a method for improving temporary road safety on river ice surfaces by adding structures. Background technique [0002] As the number of motor vehicles in the city continues to grow, the pressure on urban traffic increases sharply, especially in winter in cold regions. Smooth operation presents great challenges. In order to alleviate traffic congestion in winter, the phenomenon of using the ice surface of rivers as temporary roads exists for a long time. [0003] When the temperature drops below -10 to -30°C in winter, the surface of the water system will naturally freeze to form an ice surface. When the frozen ice surface reaches a certain thickness, it has a certain carrying capacity and can pass small vehicles to relieve road traffic congestion. However, because the firmness of the ice surface is greatly affected by the natural environment, weathering of the ...
