Novel green design method for solving problems of bridge clearance deficiency and oversteepened approach road longitudinal slope

Abstract

The invention belongs to the technical field of infrastructure construction of municipal administration, gardens, water conservancy, navigation channels and the like, and particularly relates to a novel green design method for solving the problems of bridge clearance deficiency and an oversteepened approach road longitudinal slope. More specifically, the problems of bridge clearance deficiency and the oversteepened approach road longitudinal slope are solved by adopting a method for separating a navigation channel from a water channel. According to the main design contents, a new river channel serves as the navigation channel; a reserved original river channel serves as the water channel; a water channel bridge is designed on the reserved original river channel; a navigation channel bridge is designed on the new river channel; an integral or separated river island is formed between the new navigation channel and the reserved original river channel; and the river island is subjected to green landscape design. The method has the characteristics of simple design, convenient construction, low post-maintenance expense, high traffic efficiency, environmental protection and the like. The invention provides a set of advanced, efficient, economic, practical and environmentally-friendly novel green design method for solving the problems of bridge clearance deficiency and the oversteepened approach road longitudinal slope, and the method has great economic and social effects and wide development and application prospects.

Description

technical field [0001] The invention belongs to the technical field of infrastructure construction such as municipal administration, gardens, water conservancy, and waterways, and specifically relates to a new green design method for solving the problem of insufficient clearance of bridges in municipal administration, gardens, water conservancy, and waterways, etc. The longitudinal slope of the approach is too steep. The invention relates to a method different from the existing bridge design method, which adopts the method of separating the waterway and the waterway to solve the problem of insufficient clearance of the bridge and too steep vertical slope of the approach road. Background technique [0002] Existing municipal, garden, water conservancy, waterway and other bridges have insufficient clearance and the solutions to the steep longitudinal slope of the approach road are as follows: One is to use an open bridge, and the opening methods of the open bridge show their ca...

Problems solved by technology

However, the open bridge has obvious disadvantages: vehicles, pedestrians and ships can only pass alternately, and the traffic efficiency is low. If the open bridge position is very short from the intersecting urban road, it also involves insufficient queuing distance for vehicles waiting to cross the bridge; Opening and closing consumes a lot of electric energy, the later operation and maintenance cost is high, and the investment in the whole life cycle is large; in addition, non-stop braking and starting do not take advantage of traffic safety; the increase in exhaust emissions is not conducive to environmental protection

When a bridge required for navigation is erected on a roadside river parallel to a road or road, the approach road is designed along the river bank on the side of the road intersecting the center line of the bridge longitudinal section to solve the problem of height difference between the bridge and the intersecting road, but this The method meets the requirements of the waterway, but greatly reduces the technical indicators of the road. The vehicle must brake and decelerate here, which greatly reduces the driving speed. At the same time, the exhaust emission of the vehicle increases during braking, which affects the environment.

[0004] The third is to build turntables at both ends of the bridge to solve the height difference between the bridge and the ground. However, this method is often difficult to implement due to the limitations of existing building space or land acquisition. Even if it is implemented, the ground will be replaced by rotating facilities. , high cost, large land occupation, and uncoordinated ecology
