Modified construction method for reserved wide slot of dock-type lock structure
The invention discloses a modified construction method for a reserved wide slot of a dock-type lock structure. The construction method is characterized by comprising the following steps; (1) conducting slope excavation of a foundation pit; (2) reserving a wide slot in the middle of a bottom plate; (3) constructing a main structure; (4) backfilling the soil body; (5) conducting joint close on the reserved wide slot to form a whole. The construction method can reduce adverse effect of various load of temperature load, humidity load, side wall (pier) dead load, side load and the like on the upper surface of the bottom plate during a lock construction process; maximal hogging moment of the bottom plate in the construction process is reduced; concrete cracking is prevented effectively; durability of the structure is enhanced; compared with the conventional construction method for reserved wide slot, the modified method reduces parting amount, is simple and convenient to construct, reduces template work amount, accelerates backfilling speed of soil body behind a wall, shortens construction period, enables the distribution of whole subgrade reaction to be uniform, effectively reduces tensioning degree of the surface of the bottom plate of the dock-type structure, enables whole surface tensioning degree to be uniform, facilitates reducing reinforcing steel bar using amount and fully playing tensile function of the reinforcing steel bars, and is relatively reasonable in stress of the whole structure.
