A construction method in the construction of ground connection wall with capsule-in-capsule filling technology

Abstract

The invention discloses a construction method for wall-connecting construction of a capsule-in-capsule filling technology, including S1, judging whether there is a problem with the sealing of the working capsule; S2, immediately starting the spare capsule in the working capsule if it is judged that there is a problem with the sealing of the working capsule; S3. Fill the spare bag with water and monitor the flow pressure; S4. After filling the spare bag with water, drain the working bag and ensure that the internal pressure of the working bag is greater than 150Kpa; S5. When the water intake capacity of the spare bag Close to the rated capacity, stop pressurization when the internal pressure reaches 200Kpa. This application uses the concept of traditional car tires to propose a filling solution for a bag in a bag, that is, adding a spare bag inside the working bag, and adding a wear-resistant coating and a buffer layer to the working bag itself, so that when there is a problem with the sealing of the working bag, the work can be started in time The spare bag inside the bag, and then drain the working bag to realize the successful transfer of the water storage container, which can improve the safety and stability of the filled bag, and thus ensure the 100% safety of the wall-to-wall construction of the bag-filled technology.

Description

technical field [0001] The invention relates to the technical field of underground diaphragm wall construction, in particular to a construction method in the construction of diaphragm walls with the capsule-in-capsule filling technology. Background technique [0002] There are more and more applications of underground diaphragm walls, and the construction technology of temporary filling of ground-wall joint space is also one of the key control points. Although the traditional method of construction has many shortcomings, it is safe and reliable after all; although the replacement of the traditional method with capsules is approved, it is safe and stable How to ensure 100% safety is the most critical. Contents of the invention [0003] The invention provides a construction method in the wall-connecting construction of the bag-in-bag filling technology. When the sealing of the working bag fails, the spare bag inside the working bag is started in time, which effectively impro...
