Abstract

The invention provides an anchor rod and pile plate retaining wall combined device and a construction method. The anchor rod and pile plate retaining wall combined device comprises a pile plate retaining wall and an anchor rod structure anchored in an anchor rod drill hole in a rock-soil layer, wherein heat exchange pipes and / or drainage pipes are arranged in the pile plate retaining wall and theanchor rod drill hole; the heat exchange pipes and / or the drainage pipes arranged in the pile plate retaining wall are connected with a reinforcement cage in the pile plate retaining wall; the heat exchange pipes and / or the drainage pipes arranged in the anchor rod drill hole are connected with a rod body of the anchor rod structure; and a plurality of water permeable holes are formed in the end of each drainage pipe. According to the anchor rod and pile plate retaining wall combined device, the heat exchange pipes and / or the drainage pipes are combined with an existing anchor-pulling type pile plate retaining wall, supporting and reinforcing of a slope rock-soil body can be achieved, and the anchor rod and pile plate retaining wall combined device can also be used for exchanging heat withsurrounding soil bodies or accelerating drainage of the rock-soil body.

Description

technical field [0001] The invention belongs to the technical field of slope stability and support, and in particular relates to an anchor pile-slab retaining wall combined device and a construction method thereof. Background technique [0002] In recent years, a large number of engineering construction activities brought about by the rapid development of social economy have continuously aggravated the formation of artificial slopes. Rationally carrying out slope support is one of the effective ways to reduce the destructive hazards caused by geological disasters. Therefore, the design and research of slope support has always been an important research topic. As a common form of slope support, the anchor-stayed pile-slab retaining wall has been more and more used in engineering practice in recent years. [0003] The traditional anchor-stayed pile-slab retaining wall is only used for slope support, and other functions of this structure are gradually being explored and applie...
