The invention belongs to the technical field of pile foundation construction, and particularly relates to a scene sound analysis method for interaction of a pile and a karst cave in a construction process, which comprises the following steps of: step 1, high-precision karst cave form detection: arranging crossed measuring lines with the pile foundation as a center, the length of the measuring lines being more than or equal to 20m and the spacing being less than or equal to 1m, synchronously adopting a high-energy acceleration tamper and the impact energy being more than or equal to 50kJ, active source surface waves are excited, the impact frequency ranges from 2 Hz to 5 Hz, environment noise is collected to serve as passive source surface waves, a three-component detector array is used for receiving, and the sampling rate is larger than or equal to 500 Hz. According to the method for analyzing the interaction scene sound of the pile and the karst cave in the construction process, by setting the method for analyzing the interaction scene sound of the pile and the karst cave in the construction process, wave velocity changes in the vertical direction and the horizontal direction and anomalies in high-speed and low-speed areas are analyzed, and the thickness of a covering layer and the burying depth of bed rock are deduced; the development depth, the scale and the space distribution condition of the monolith and the karst caves are determined.

A method of manufacturing a gas heater heating element including a support and channel structure with a plurality of channels formed in the monolith includes shaping an electric heating element and at least partially coating the electric heating element with at least one coating material. The at least partially coated electric heating element is positioned in a mold for producing the monolith. The monolith is produced and surrounds the at least partially coated electric heating element. The coating material of the at least partially coated electric heating element is removed. The gas heater heating element includes at least one electric heating element in the monolith and the electric heating element is guided in the plurality of channels of the support. Heat within the plurality of channels is configured to be transferred by the electric heating element to a gas flowing through the plurality of channels to heat the gas.

Method of preparing a porous material includes preparing a mixture of from about 10 to about 30% by mass of a matrix material, from about 20 to about 60% by mass of a plurality of particles, from about 20 to about 60% by mass of a porogen, and from about 1 to about 10% by mass of an interfacial compatibilizer. The matrix material and the porogen may be selected so as to be phase separated in the mixture. The method may further include placing the mixture into a form; initiating a solidification of the matrix material during which the porogen remains nonvolatile and the matrix material and the porogen remain phase separated; and removing at least a portion of the porogen to obtain the porous material. Porous materials produced by the methods. Microfluidic channels produced by the methods.

This application discloses a self-elevating rock-embedded platform, comprising: a hull platform with multiple pile-planting positions; lifting legs mounted on the hull platform and capable of lifting to drive the hull platform to switch between a relocation state and a construction state; a rock-embedded drilling rig mounted on the hull platform for rock-embedded construction at the pile-planting positions; and hoisting equipment mounted on the hull platform. This application reduces the relocation time from one or even two days to one or two hours, significantly increasing platform relocation efficiency. Since the rock-embedded drilling rig does not need to be disassembled during platform relocation, the safety and reliability of the relocation are higher. During platform relocation, there is no need for a large floating crane vessel for relocation construction, which is the most expensive construction machinery in rock-embedded construction; this solution will significantly reduce the cost of rock-embedded construction. The floating hull platform, compared to the prior art which requires disassembling the crane, significantly improves safety and boundary conditions.
