Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with the drawings.

[0036] The invention provides a construction method of a temporary bridge for a river with high flow velocity and large increase, including the following steps:

[0037] The first step is to construct pile foundations in the river course. There are several groups of pile foundations evenly distributed in the middle of the river course. Each group of pile foundations includes two, namely the first pile foundation and the second pile foundation. Among them, the first pile foundation Placed at the upstream of the river, the second pile foundation is placed at the downstream of the river, such as figure 1 As shown, when building:

[0038] First, build a work platform in the river:

[0039] Two flat boats are connected side by side through I-beams to form work platforms 1-7, and a gap is set between the two flat boats, and the size of the gap is determined according to the technological dimen...

Abstract

The invention provides a construction method of a water-discharge temporary bridge for a high-flow-rate and high-rise-degree river channel. The method includes the steps of firstly, constructing pilefoundations in the river channel, wherein a plurality of groups of pile foundations are evenly distributed in the river channel, and each group of pile foundations comprises a first pile foundation located at the upstream of the river channel and a second pile foundation located at the downstream of the river channel; secondly, building a bridge deck system on every two adjacent groups of pile foundations. By the method, the height of the temporary bridge can be reduced, the length of the temporary bridge can be reduced, high safety can be achieved, and cost can be lowered effectively.

Description

Technical field [0001] The invention relates to the field of bridge construction, in particular to a construction method of a temporary bridge used in a river with high flow velocity and large increase. Background technique [0002] At present, the commonly used temporary bridge in China is the Bailey beam temporary bridge, which has the advantages of easy erection, easy dismantling, low cost and strong operability. However, in practice, some temporary bridges need to be built on the river where the flood increase is more than ten meters during the flood season. Due to the flood, the elevation of the temporary bridge will be more than ten meters higher than the normal water level. The length of the temporary bridge is nearly doubled to meet the construction requirements. Claim. Such a high-level temporary bridge is more than ten meters above the normal water level. If the Bailey beam temporary bridge is used for construction, the stability of the transverse bridge will be low, a...
