Spiral anchor-anchor rod double-anchor composite foundation and construction method thereof
The invention provides a spiral anchor-anchor rod double-anchor composite foundation and a construction method thereof. The spiral anchor-anchor rod double-anchor composite foundation comprises a spiral anchor and an anchor rod. The spiral anchor is located in a soil body and is of a hollow structure. The anchor rod penetrates through the hollow structure and is located in the rock mass below the hollow structure. The anchor rods are connected with the spiral anchors and the rock mass to form the double-anchor composite foundation. According to the technical scheme, the bearing capacity of the undisturbed soil on the upper portion can be utilized, the strength of the bed rock on the lower portion can also be utilized, and an effective foundation form is provided for the stratigraphic structure of the upper soil and the lower rock. The invention further provides a construction method of the spiral anchor-anchor rod double-anchor composite foundation. The construction method comprises the steps that the spiral anchor is screwed into a soil body; the anchor rod penetrates through the spiral anchor to be arranged in the rock mass; and the anchor rod and the spiral anchor are poured. According to the construction method, the double-anchor composite foundation can be formed in the upper-soil lower-rock stratum, and the bearing capacity of the undisturbed soil and the bearing capacity of the undisturbed bedrock are jointly exerted.
本发明提出一种螺旋锚‑锚杆双锚复合基础及其施工方法，所述螺旋锚‑锚杆双锚复合基础包括螺旋锚和锚杆；所述螺旋锚位于土体中，且呈中空结构；所述锚杆贯穿所述中空结构，且位于下方的岩体中；所述锚杆分别与所述螺旋锚和所述岩体连结，形成双锚复合基础。本技术方案既能利用上部原状土的承载力，也能利用下部基岩的强度，为上土下岩的地层结构提供了一种有效的基础形式。本发明还提供了一种螺旋锚‑锚杆双锚复合基础的施工方法，包括将螺旋锚旋拧入土体中；将所述锚杆穿过所述螺旋锚置于所述岩体内；对所述锚杆和所述螺旋锚进行浇筑。本施工方法能够在上土下岩的地层中形成双锚复合基础，共同发挥原状土和原状基岩的承载力。
