Ultrasonic wave based soft foundation treatment solidification speed increasing method

Abstract

The invention discloses an ultrasonic wave based soft foundation treatment solidification speed increasing method. The method includes steps: determining transmitting frequency and power of a probe ineach ultrasonic treatment device according to ultrasonic propagation attenuation characteristics and a drain hole pitch; uniformly mounting multiple ultrasonic treatment devices on the outer wall ofa drain pipe along the axial direction of the drain pipe; starting the ultrasonic treatment devices to perform treatment for certain time, so that the soft soil filtration coefficient is increased byan ultrasonic cavitation effect, and soft foundation treatment solidification speed is further increased. The method has advantages that soft soil settlement can be accelerated, a soft soil treatmentperiod is shortened, and the method has positive significance to highway soft foundation treatment and also has a certain guidance function for marine soft foundation treatment in reclamation projects.

Description

technical field [0001] The invention relates to the field of soft foundation treatment, in particular to a method for increasing the consolidation speed of soft foundation treatment based on ultrasonic waves. Background technique [0002] In the process of highway construction and large-scale building construction, it is often necessary to consolidate soft foundations. Plastic drainage board drainage consolidation technology is one of the methods commonly used in highway soft foundation treatment construction. The technology is relatively mature. Plastic drainage boards and overpressure earthwork The general settlement period for soft foundation is 6-12 months. Compared with other soft ground treatment methods, plastic drainage boards are simple and economical, but this method has a long settlement period, overloading and unloading have a certain impact on construction. [0003] At present, the working cycle of soft foundation treatment is long, and the highway construction...

Problems solved by technology

Compared with other soft ground treatment methods, plastic drainage boards are simple and economical, but the settlement period of this method is long, and overloading and unloading have a certain impact on construction

[0003] At present, the working cycle of soft foundation treatment is long, and the highway construction period is generally 2 years. During the soft foundation treatment period, it has a huge impact on subgrade structures and bridge construction: affecting structures within the soft foundation range of the entire line, especially the construction access roads of bridge projects Planning, it is difficult to use the subgrade inside the red line as a construction access road in the soft foundation treatment section, which increases the length of the access road outside the red line

[0004] Theoretically, soft foundation treatment is generally not on the key lines of the construction period, but due to the complexity of the construction environment of highway projects, the cycle of soft ground treatment often indirectly affects the operations on key lines, and it is necessary to continuously adjust the direction of key lines and increase management Difficulty, increasing temporary investment or affecting the quality of soft foundation treatment
