The construction method of bridge construction by fishing method of bridge machine

Abstract

The invention relates to a construction method for constructing a bridge by the fishing method of a bridge machine, which uses the fishing method bridge erecting machine, auxiliary equipment and facilities, and adopts the fishing method construction technology to complete the erection construction of pile foundations, caps, bridge piers and bridges. The front part of the fishing method bridge erecting machine adopts a local double-girder mechanism, and additional front auxiliary legs and three cranes are added, two of which are located on the single guide beam and are used for drilling rigs, cap formwork, pier formwork, The hoisting of auxiliary equipment and facilities such as steel bars and the transportation of construction waste; the other crane is located on the local double girder, which is used for lateral movement and short-distance vertical movement of equipment within the cap platform, and the front auxiliary legs can be supported on the ground. Cooperate closely with 3 cranes to complete the fishing method construction work. The invention does not set up a construction access road, and minimizes the amount of green plant transplanting, only transplanting within the projection range of the abutment, so that the original landform can be more completely preserved, and the activity space of wild small animals can be protected as much as possible, which is beneficial to the maximum maintain the harmony between man and nature.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a construction method for constructing a bridge by means of fishing with a bridge machine. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment; the auxiliary structures refer t...

Problems solved by technology

[0011] At present, during bridge construction, it is usually necessary to build a construction access road to carry out the construction of the pile foundation and cap platform. The construction of the construction access road will cause great damage to the environment, and at the same time have a greater impact on wild animals and plants under the bridge
