Abstract

The invention discloses a counterarch bottom board structure of an unevenly and softly anchored plunge pool. The counterarch bottom board structure comprises a plurality of sections of concrete counterarch bottom boards (1) which are transversely distributed along the counterarch bottom board of the plunge pool, concrete arch bases (2) and anchoring steel bars (6); the concrete counterarch bottom boards (1) which are arranged at the different transverse locations of the plunge pool are provided with the anchoring steel bars (6) in different amounts according to the principles of the small amount of central boards and the large amount of margin boards, and the anchoring steel bars (6) are provided with certain length of free sections. By adopting the counterarch bottom board structure of the unevenly and softly anchored plunge pool, the needed amount of the anchoring bars can be effectively reduced while the security of the plunge pool is guaranteed. In addition, when bearing a heavier thrust at springer, the counterarch bottom board structure of the unevenly and softly anchored plunge pool, provided by the invention, can realize the joint bearing between the anchoring bar and the arch base on the counterarch bottom board structure of the plunge pool, and is beneficial to the anti-pressing characteristics of the concrete of the arch base and the over load capacity of the arch structure.

Description

technical field

[0001] The invention relates to the technical field of energy-dissipating and anti-scouring facilities for drainage structures, in particular to an anti-arch bottom plate structure of an uneven and flexible anchor stilling pond. Background technique

[0002] At present, the anchoring method of the anti-arch floor structure of the stilling pond used in the energy dissipation and anti-scouring project is usually uniform distributed rigid anchorage, and the same amount of anchoring reinforcement is arranged at different positions on the anti-arch floor of the stilling pond. Due to the effect of the "arch" of the stilling pond, the safety factors of the plates that make up the anti-arch floor of the stilling pond are very different. Generally, the safety factor of the center plate is the largest, and the safety factor of the edge plates is the smallest, thus causing When the anchoring reinforcement on other plates yields, the anchoring reinforcement of the center...
