Technical Field
The utility model belongs to the technical field of construction, concretely relates to interim river-crossing steel trestle of being under construction.
Background
The trestle is a temporary bridge structure which is shaped like a bridge and is used for loading and unloading goods, loading and unloading passengers, and specially used for construction site traffic, mechanical arrangement or overhead operation in a station, a port, a mine or a factory; bridge buildings for rolling stock to drive on and off ferry ships in railways and ferries; temporary bridge facilities built for transporting materials, equipment and personnel in civil engineering; the trestle is divided into a wood trestle and a steel trestle according to the adopted materials.
The steel trestle is the most common temporary bridge structure, has the advantages of large bearing capacity and high construction speed, and is widely applied to various construction scenes. When setting up the steel trestle, it is direct to bury the tip of steel girder in the steel trestle in the soil of crossing regional both sides usually, and in the river construction of striding, because of being close to the reason of river, bury the soil of steel trestle tip relatively soft often underground, simultaneously because the rig, mechanical equipment such as crane and construction vehicle all have great dead weight, when these equipment pass through from the steel trestle, not only make the steel trestle bear great load, there is great horizontal thrust to the steel trestle simultaneously, make the steel trestle take place horizontal displacement easily, in the use, the tip of steel trestle takes off easily and leads to the steel trestle to collapse, there is great potential safety hazard.
In view of the defects of the existing steel trestle, the applicant is based on professional knowledge and abundant practical experience of years of engineering application of the products, and actively carries out research and innovation by matching with the application of theory so as to create a temporary river-crossing steel trestle for construction, so that the temporary river-crossing steel trestle has higher practicability.
Disclosure of Invention
The above-mentioned not enough to prior art, the to-be-solved technical problem of the utility model is to provide a river steel trestle is striden temporarily in construction, avoids the steel trestle problem that takes place horizontal displacement easily to the security of river transportation is striden when improving the construction.
In order to solve the technical problem, the utility model adopts the following technical scheme:
a temporary river-crossing steel trestle for construction comprises two concrete abutment platforms which are vertically arranged side by side;
