Description

TECHNICAL FIELD

[0001] The utility model relates to hydraulic engineering construction technical field especially is related to a once cast forming's lock chamber wall combination formwork. BACKGROUND

[0002] China's water transport development is coming to a major historical opportunity, and the construction technology of ship lock also enters the leap-forward development. The ship lock made of reinforced concrete has a regular groove structure in cross section. The vertical floating mooring column groove on the lock chamber wall plays a crucial role in ensuring the safe berthing of passing ships.

[0003] In the traditional floating mooring column groove construction process, in order to ensure that the floating mooring column can achieve very high installation precision, the two-stage concrete pouring construction method is often used. Before the two-stage concrete pouring construction is carried out, the construction personnel need to carefully chisel the contact surface of the first-stage concrete, so as to ensure the quality of the subsequent concrete pouring, make it tightly combined with the first-stage concrete, and form a solid and stable overall structure. At the same time, due to the particularity of the construction environment, a high steel pipe support frame needs to be erected to stably reinforce the two-stage floating mooring column groove formwork. In this process, the construction personnel need to accurately complete each erection step in the high-altitude working environment to ensure the firmness and stability of the support frame and provide a solid foundation guarantee for the subsequent concrete pouring work.

[0004] However, this traditional construction process, although it can ensure that the verticality of the roller guide groove and the clearance size meet the design requirements to some extent, also has many difficult-to-overcome drawbacks. Because the internal space of the roller guide groove is extremely small and is full of a large number of tie bars, it makes the concrete vibrating work extremely difficult. The vibrating rod is difficult to fully exert in the small space, and it cannot ensure that the concrete can be uniformly and densely filled in every corner, resulting in uneven concrete quality and unsatisfactory overall appearance quality, such as pockmarks and honeycombs. In addition, for the construction workers, it is extremely inconvenient to operate in such cramped and complex construction environment, which not only greatly reduces the construction efficiency, but also has a great safety risk. Workers may collide or fall in the process of concrete pouring, vibrating, and formwork installation and removal, etc., which poses a serious threat to their own life safety.
