Embodiment Construction
[0029] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0030] see Figure 1 to Figure 3 , the present embodiment provides a construction method in the construction of a wall with a capsule-in-capsule filling technology, which includes the following steps:
[0031] S1. According to the pressure change of working bag 1 displayed in real time by the pressure and flow monitoring equipment, the working bag 1 will drop from 150Kpa to 100Kpa in a straight line within 5-10 minutes, and then combined with the pipeline sealing inspection, determine whether there is a problem with the sealing of working bag 1;
[0032] S2. If it is judged that there is a problem wi...

Abstract
The invention discloses a construction method in underground continuous wall construction adopting a bag-in-bag filling technology. The construction method in underground continuous wall constructionadopting the bag-in-bag filling technology comprises the following steps: S1, judging whether sealing for a working bag goes wrong or not; S2, if the sealing for the working bag is judged to go wrong,immediately starting a standby bag in the working bag; S3, carrying out water charging on the standby bag, and monitoring a flow and a pressure; S4, after the water charging is carried out on the standby bag, carrying out water drainage on the working bag, and ensuring that the internal pressure of the working bag is greater than 150Kpa; and S5, when the water inlet capacity of the standby bag isapproximate to a rated capacity and the internal pressure reaches 200Kpa, stopping pressurization. According to the construction method in underground continuous wall construction adopting the bag-in-bag filling technology, by virtue of a traditional concept of a vehicle tire, a bag-in-bag filling scheme is disclosed, that is, the standby bag is added into the working bag, and moreover, the working bag is additionally provided with a wear-resistant coating layer and a buffer layer; and when the sealing for the working bag goes wrong, the standby bag in the working bag is started in time, thenthe water drainage is carried out on the working bag, and successful transfer for a water storage container is realized, so that the safety and stability of the filling bag can be improved, and thenthe 100% safety of the underground continuous wall construction adopting the bag filling technology is ensured.
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...
