Embodiment Construction
[0041] Examples see figure 1 As shown, this long-span continuous arch structure includes at least two side-by-side tunnel holes 1, and includes a small arch section 2 and a large arch section 3 in the long direction, and the large arch section and the small arch section Between transition section 4 variable diameter transition, in this example, the middle section is small arching section 2, and both sides are large arching section 3.
[0042] see figure 2 , image 3 As shown, the roof of the side-by-side tunnel holes in the cross section of the large arching section 3 is a continuous arched structure cast in one piece; the bottom axillary corner of the tunnel hole in the cross section of the large arching section is a slope.
[0043] see Figure 4 As shown, the roof of the side-by-side tunnel holes in the cross-section of the small arching section 2 is an integrally cast flat plate structure; the bottom and top axillary corners of the tunnel holes in the cross-section of t...

The invention discloses a long-span continuous arch structure, a top plate supporting system and a construction method for the top plate supporting system. The long-span continuous arch structure comprises at least two tunnel holes arranged side by side, a small arch camber section and a large arch camber section, wherein the small arch camber section and the large arch camber section are in the length direction of the structure, and reducing transition is achieved between the large arch camber section and the small arch camber section through a transition section; top plates of the tunnel holes arranged side by side in the cross section of the large arch camber section are of integrally poured continuous arch structures; top plates of the tunnel holes in the cross section of the small arch camber section are of integrally poured slab structure. Regarding construction for the reducing structure, the invention further discloses the top plate supporting system and the construction method. In order to adapt to project features of tight schedule, complex structure, high quality standard and the like and fully meet prospective safety and stability, the structure of the supporting systemis safe and reliable; selected materials are common in use and can be circularly utilized; the selected model of a formwork is definite in stress, the construction measure is accurate, building and dismantling are convenient, and the construction is convenient. The top plate supporting system can be widely applied to concrete pouring supporting systems of long-span tunnel top plates of complex structures.
Description
technical field [0001] The invention relates to the field of building construction, in particular to a large-span structure and a construction method thereof. Background technique [0002] As a transit station for various means of transportation, the airport needs to meet the smooth passage of subways, buses and other means of transportation, as well as the stranded passengers. Therefore, the airport structure is becoming more and more complex, including above-ground structures, underground structures, etc. In order to meet large The demand for space will often form a long-span continuous structure, such as a long-span continuous arch structure. Due to the large construction load, complex structure, high quality standard, and high and inconsistent arch height of this structure, there will be some problems in the general support system and construction methods. Disadvantages, taking the common trolley formwork system as an example, the general routine engineering basically us...
