Underground engineering waterproof board reinforcement method
The invention discloses an underground engineering waterproof plate reinforcement method, and relates to the technical field of waterproof plates. The underground engineering waterproof plate reinforcement method comprises the following steps that models are established for an existing waterproof plate, the main stress control working condition is water buoyancy, force gear design is conducted on the waterproof plate based on a reverse water buoyancy stress mode, multiple water buoyancy load effects are conducted on the two models through finite element analysis and calculation, and the waterproof plate reinforcement effect is achieved. And according to finite element analysis, the length of additional steel bars added in a stress increasing area and an actual construction drawing can be obtained after the full-length steel bars are laid. According to the underground engineering waterproof board reinforcement method, improvement measures are provided aiming at the problems in existing basement waterproof board reinforcement, engineering hidden dangers can be eliminated, compared with an existing national standard radiation reinforcement method, the reinforcement method has the advantages that additional reinforcements on the edge of a thickening area are consistent with the direction of bottom plate stress reinforcements, the effective height h0 is not affected, and the reinforcement effect is good. The reinforcement direction is consistent with a finite element stress calculation result.
