Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] see figure 2 , the root of the over-high gravity retaining wall 5 is provided with an arm-type wall 1 close to it, and the bottom of the arm-type wall 1 is connected with an arm-type wall adjacent to one end of the over-high gravity type retaining wall 5 1 Apply a prestressed anchor rod 2 obliquely downward to one side of the over-high gravity retaining wall 5, and the end of the bottom of the arm-type wall 1 away from the over-high gravity retaining wall 5 is connected with a support arm by a hinge 4 Type wall 1 applies the reinforced concrete pile 3 of upward supporting force, and hinge 4 is the longitudinal steel bar that inserts reinforced concrete pile 3 after 3 intersections.

[0016] see figure 2 , the moment M formed by the downward component force of the pressure N of the prestressed anchor rod 2 on the buttress wall 1 and t...

Abstract

The invention discloses an anchoring and retaining structure for reducing support height of existing overhigh retaining wall. A counterforted retaining wall (1) adhered to the root portion of an overhigh gravity retaining wall (5) is arranged at the root portion, one end of the bottom of the counterforted retaining wall (1) close to the overhigh gravity retaining wall (5) is connected with a prestressed anchor rod (2) applying inclined downward pressure to the counterforted retaining wall (1) towards one side of the overhigh gravity retaining wall (5), and one end of the bottom of the counterforted retaining wall (1)away from the overhigh gravity retaining wall (5) is connected with a reinforced concrete pile (3) applying upward support force to the counterforted retaining wall (1) through a hinge (4). The anchoring and retaining structure for reducing the support height of the existing overhigh retaining wall is small occupied area and used for reducing the support height of the existing overhigh retaining wall.

Description

technical field [0001] The invention relates to a retaining structure, in particular to an anchoring retaining structure for reducing the retaining height of an existing excessively high retaining wall. Background technique [0002] my country's "Technical Regulations for Building Slope Engineering" GB 50330-2002 has some regulations on the suitable retaining height of various retaining structures. This is because if the retaining height of the retaining structure exceeds its suitable retaining height too much, it The chances of damage will be much greater. For example, Table 3.4.4 of this code considers that for soil slopes, the suitable retaining height of gravity retaining wall is 8m. However, due to economic reasons, gravity retaining walls were often used to support slopes with a height greater than 8m. After all, gravity retaining walls are relatively low in cost. Gravity retaining wall retaining structure exceeding its suitable retaining height too much has become an...
