[0022] Example 1

[0023] From both sides of the river, start the construction of the access road, the temporary bridge and the island cofferdam of the cap at the same time, until the intersection in the middle to complete the construction of the access road, the temporary bridge and the island cofferdam of the cap. The beginning of the construction includes the steps: (a) from the side of the river 4, 5 in order to build the island of the first construction access road 2-1 and the first temporary bridge 3-1; (b) in the first The pile foundation of the first temporary bridge 3-1 is constructed on the island of Yibian Bridge 3-1. The pile foundation of the first temporary bridge 3-1 adopts the construction technology of underwater impact bored piles; (c) During the construction of the first temporary bridge 3 -1 pile foundation while filling the island of the first cap 1-1 on the side wall of the first construction access road 2-1, and construct the island of the first cap 1-1 Th...

Abstract

The invention discloses an island and cofferdam construction method for roads, bridges and bearing platforms. Constructions started simultaneously from the two sides of a riverway both comprise the following steps of: building an island of a first construction rod and an island of a first bridge orderly sequentially from one side of the riverway; constructing a pile foundation of the first bridge on the island of the first bridge; filling an island of a first bearing platform on one sidewall of the first construction road while constructing the pile foundation of the first bridge, and constructing a pile foundation of the first bearing platform on the island of the first bearing platform; after the pile foundation of the first bridge is completed, spanning a bailey frame assembled steel truss girder of the first bridge over pier studs of the pile foundation of the first bridge; and repeating the operations from the first step to the fourth step at the front end of the first bridge until the island and cofferdam constructions of the roads, the bridges and the bearing platforms of the whole riverway are completed from the two sides to the middle part of the riverway. With the method, no pollution is caused on the Yellow River and the environment is protected.

Description

technical field [0001] The invention relates to an island-building cofferdam construction method, in particular to an island-building cofferdam construction method for an access road, an access bridge and a cap. Background technique [0002] With the rapid development of our country's national economy, the investment in road and bridge construction is increasing day by day. In bridge construction, there are more and more bridges crossing deep valleys and large rivers. There are currently many construction methods on how to obtain site conditions similar to "land" in water to meet the construction needs of pile foundations and caps of bridge piers. When the terrain where the bridge is located has a large height difference and the terrain is complex, some of the bridge piers are located in the valley, and the other part of the bridge piers are located in the river. The construction of the bridge piers located in the river will involve the construction of island cofferdams for...
