Abstract
The present invention provides a composite supporting structure combining fabric-form bag-behind-wall grouting and high-strength support frames and a construction method thereof, relating to the field of underground engineering support. The composite supporting structure comprises multiple sections of composite supporting units sequentially arranged in a longitudinal direction, wherein each of the composite supporting units comprises support frame, circumferential fabric-form bags are arranged outside top plate sections and side sections of the support frames, and longitudinal fabric-form bags and longitudinal supports are arranged in an alternating manner outside bottom plate sections of the support frames. The present invention forms an active-passive combined full-section composite high-strength supporting structure that may solve the problems of support difficulties such as high ground pressure, strong disturbance and the like of deep wells.
