Example

[0071] Implementation application example 1:

[0072] The span layout of a newly built super bridge is 1x40+(92+172+92)m, the main bridge is 356m in total length, the main bridge is 92+172+92 corrugated steel web prestressed concrete continuous rigid frame bridge, and the approach bridge is 1-40m prestressed Stressed concrete prefabricated small box girder with a total length of 404.5m. The main girder of the main bridge adopts a single-box single-chamber prestressed concrete continuous box girder with variable cross-section corrugated steel webs. The main pier adopts double-limbed solid piers, and the transition pier adopts double-column solid piers. The lower foundation adopts the pile cap to connect the group pile foundation. The 2# and 3# piers are all located in the water. The pile foundations are constructed by erecting trestle bridges and steel platforms, and then steel platforms are used for steel box cofferdam construction. The main pier caps of 2# and 3# are integral, t...

Abstract

The invention relates to the technical field of steel suspension boxes, in particular to a steel suspension box side plate and base plate connection device without top seal concrete and a constructionmethod thereof. The steel suspension box side plate and base plate connection device is characterized by comprising a base plate 11, supporting beams 10 and limiting grooves. The base plate 11 is installed on the supporting beams 10 with L-shaped rabbets 9 in end portions. Each L-shaped rabbet 9 is provided with one limiting groove. A side plate structure is installed on the limiting grooves in aconnected manner. According to the construction method of the steel suspension box side plate and base plate connection device without top seal concrete, construction is carried out according to a site construction drawing. The steel suspension box side plate and base plate connection device without top seal concrete and the construction method thereof have the characteristics that the concrete needed for bottom sealing of the steel suspension box can be omitted, a large amount of concrete can be saved, the good water stop effect can be achieved, installation and detachment are convenient tocarry out, the structure is solid, safe and reliable, a construction safety factor is high, and so on.

Description

technical field [0001] The invention relates to the technical field of steel suspension boxes, in particular to a bottom-free concrete steel suspension box side plate and bottom plate connection device and a construction method thereof. Background technique [0002] In recent years, with the vigorous development of expressway construction in my country, super-large bridges across large rivers, bays, straits, etc. have emerged continuously. The construction of a large number of deep-water bridges will inevitably put forward higher requirements for the construction of bridge foundations. my country has a vast territory, complex and changeable hydrological, geological, and climatic conditions, and the methods and degrees of difficulty of bridge overwater foundation construction vary. The overwater foundation construction has many invisible unknown factors and large variables, especially under complex hydrogeological conditions. Bridge foundation construction is difficult and has...
