[0002] Generally, design units involved in temporary pipeline relocation will consider the entry of pipelines into the corridor. Due to cost reasons, the corridor is usually small in size and has insufficient internal clearance. The corridor structure cannot be cast as a whole, so they can only construct the bottom plate and side walls first, and then cast the top plate after the pipelines enter the corridor.

[0003] The pouring of the top slab usually requires the erection of a scaffold, but the clear cross-sectional dimensions of the tunnel are small and there is pipeline interference, which makes the erection of the scaffold difficult.

[0004] Therefore, it is necessary to design a support system for the top plate formwork of a corridor with small clearance section, which can avoid the influence of small clearance section size and pipeline interference, and is quick and convenient to construct and suitable for corridors with small clearance section, so as to solve the current technical problems. Summary of the invention

[0005] In view of the deficiencies in the prior art, the utility model provides a bracket-free top plate formwork support system suitable for small clearance section corridors, which is quick and convenient to construct and avoids the influence of small clearance section size and pipeline interference.

[0006] The technical solution of the utility model is: it is suitable for a support-free top plate formwork support system of a pipe gallery with a small clearance section, comprising a plurality of parallel pipe gallery side walls, the tops of the pipe gallery side walls are evenly arranged with main keels perpendicular to them, the tops of the main keels are all arranged with secondary keels perpendicular to them, and the tops of the secondary keels are paved with top plate formwork.

[0007] A reserved hole matching the main keel is provided on the top of the side wall of the pipe gallery.

[0008] The reserved holes are circular holes with a diameter of 110 mm, and the spacing between the reserved holes is ≤200 mm.

[0009] The main keel and the secondary keel are square wood, channel steel or I-beam.

[0010] The main keel is a 100mm*100mm square wood, and the secondary keel is a 50mm*50mm square wood.

[0011] The distance between the secondary keels is ≤100mm.

[0012] The top plate template is bamboo plywood.

[0013] The top plate template is a bamboo plywood with a thickness of 12 mm.

[0014] The beneficial effects of the utility model are as follows: In the utility model, the main keel is supported by the side wall of the pipe gallery, and then the secondary keel and the top plate formwork are laid in sequence on the top of the main keel. The top plate formwork is supported in a bracket-free manner, avoiding the problem of difficulty in setting up brackets due to small clearance cross-sectional dimensions and pipeline interference, and the construction is quick and convenient.
