This invention discloses a construction method for rotary drilling piles used in water conservancy and hydropower engineering. The method involves setting up a first row and a second row of rotary drilling piles at a predetermined elevation on the river-facing side of the foundation pit. These piles interlock and their tops are flush. A capping beam is also included at the top of the first and second rows of rotary drilling piles, connecting and fixing them into a vertical, closed wall. A diaphragm wall is also installed inside the foundation pit, with one end connected to the solid wall and the other end connected to the bedrock. The interlocking of the two rows of rotary drilling piles, along with the construction of the capping beam and diaphragm wall at the top of the piles, forms a continuous, closed foundation pit protection structure. The entire construction process facilitates the excavation and layout of the outlet retaining wall foundation after the flood season, saves construction time, reduces construction costs, and provides functions such as cofferdam seepage prevention, scour prevention, soil retention, foundation pit protection, and foundation bearing capacity.

The application solves the problems of formaldehyde wastewater treatment efficiency, sewage treatment cost, formaldehyde wastewater treatment capacity and formaldehyde conversion selectivity.

The application provides a method for preparing a defect-free MOF membrane by a MOF gradient distribution seeding method. According to the fact that the density of ZIF-8 seeds is greater than the density of a polymer solution, a gradient distribution of the ZIF-8 seeds in a phase inversion membrane is obtained, and abundant nucleation sites are provided for subsequent ZIF-8 layer growth. The distribution of the ZIF-8 seeds in the membrane holes increases the rigidity of the phase inversion base membrane, and simultaneously increases the adhesion of the surface of the base membrane and the ZIF-8 layer. The addition of tannic acid in the ZIF-8 precursor solution assists the growth of the ZIF-8 layer, the tannic acid has abundant hydroxyl groups, provides CO2 groups, and improves the selectivity of the membrane for separating H2 / CO2. The ZIF-8 seeds in the compact defect-free ZIF-8 membrane rich in hydroxyl groups have a gradient distribution, which improves the mechanical properties of the base membrane and the adhesion of the ZIF-8 layer, and the ZIF-8 membrane prepared by directly seeding ZIF-8 seeds on the base membrane shows obvious superiority.

The application provides a fast phase unwrapping method based on tail non-convex regularization, and aims at solving the following two technical problems of the existing phase unwrapping algorithm: one is that details are lost due to the discontinuity of the image edge; and the other is that it is difficult to accurately realize phase unwrapping when facing high complexity or large phase jumps. The steps of the application are as follows: based on the wrapped image, a non-convex tail optimization model with box constraint is constructed; the non-convex tail optimization model is solved by using a completely split primal-dual algorithm under the condition that the support set is empty, so that an initial phase is obtained; errors in the initial phase estimation are corrected through tail minimization, and the support set is dynamically updated, so that an unwrapped image is obtained. Compared with the traditional phase unwrapping algorithm, the application combines the non-convex regularization with the tail minimization strategy, so that the accuracy and robustness of the phase unwrapping are improved, and the application has significant superiority in key evaluation indexes such as signal-to-noise ratio and structural similarity.
