Construction method for immersed tube ballasting system dismounting and concrete replacement
The invention relates to the technical field of immersed tube ballasting systems, in particular to a construction method for immersed tube ballasting system dismounting and concrete replacement. The construction method comprises the steps that on the premise of guaranteeing that the anti-floating coefficient is larger than 1.05, construction is selected to be started from an end water bag at the first end of the first side of the axis of an immersed tube, through an immersed tube ballasting system pipeline control device, corresponding valves are adjusted, the designed water quantity is introduced to water bags needing water injection, from the end water bag on the first side to an end water bag on the second side, the end water bags are sequentially and alternately dismounted on the two sides, concrete ballasting is carried out till all the water bags are dismounted, and concrete ballasting construction is finished; and after immersion tube mounting is finished, the above method is adopted, under the condition that the anti-floating coefficient of the immersion tube is larger than 1.05, the water bags are dismounted after being subjected to water draining one by one so as to achieve concrete replacement in sequence, operation is simple and ordered, and the replacement efficiency is high; and the anti-floating coefficient of the immersion tube is controlled, the immersion tubecannot suffer from the problem of upward floating or displacement, and the mounting quality and construction safety of the immersion tube are guaranteed.
本发明涉及沉管压载系统技术领域，具体涉及一种沉管压载系统拆除及置换混凝土施工方法，包括：在保证满足抗浮系数大于1.05的前提下，选择从所述沉管轴线第一侧的第一端的端部水囊开始施工，利用沉管压载系统管路控制装置，通过调节相应的阀门，对需要注水的水囊通入设计水量，从第一侧的端部水囊至第二侧的端部水囊，两侧依次交替拆除端部水囊并压载混凝土，直至所有水囊拆除、压载混凝土施工完毕；在沉管安装完成后，采用上述方法，在满足沉管抗浮系数大于1.05的情况下，逐个将水囊排水后拆除，来依次置换混凝土，简单有序，置换效率高，而且通过对沉管抗浮系数进行控制，沉管不会发生上浮或移位的问题，保证了沉管安装质量及施工安全。
