The invention relates to the field of buildings, in particular to a vertical pre-stressed anchor cable construction method, which comprises the following steps: firstly, limiting the setting range of an anchor cable through drilling, and in the step of anchor cable setting, driving a steel strand to vertically descend through a guide cap so as to subsequently form a vertically arranged anchor cable, so that the occupied horizontal space is reduced; primary grouting is conducted in the first blind hole through the first grouting pipe, so that the anchor cable is basically fixed and formed, then secondary grouting is conducted through the second grouting pipe after the first grouting pipe is pulled out, cement is evenly injected to the periphery from the grout outlet, and the cement evenly injected to the periphery flows to the bottom of the anchor cable under the action of gravity; and uniform strength of the anchor cable in all directions is ensured. After grouting is completed, all the ...

The invention discloses a large-thickness variable-cross-section raft foundation construction technology. The technology comprises the steps that a bottom-layer retaining wall is formed, a top-layer retaining wall is formed through pouring, a raft reinforcing steel bar and steel pipe supporting frame is formed, and a raft foundation is poured and formed in a layered mode. The large-thickness variable cross-section raft foundation construction process can effectively solve the construction problem caused by large thickness and large base height difference, effectively deals with a soil layer structure, is very firm in foundation structure, greatly reduces the use amount of reinforcing steel bars, effectively reduces the cost, and is more convenient and efficient in construction.
