Special formwork of foundation bolt pile hole for secondary grouting method and application method for special formwork
The invention discloses a special formwork of a foundation bolt pile hole for a secondary grouting method and an application method for the special formwork. The special formwork comprises steel formworks, upper groove plates, middle groove plates, lower groove plates and fastening angles. The steel formworks are in an isosceles trapezoid geometric figure shape. The upper groove plates, the middle groove plates and the lower groove plates are fixedly welded to the upper portions, the middle portions and the lower portions of the steel formworks respectively to place the fastening angles during angle connecting. Steel bars with the diameter phi of 10 mm are adopted in the fastening angles, and after bending, two sides are equal, and the 90-degree right angle is formed between the two sides. During angle connecting, the two steel formworks are fixedly connected together through the upper groove plates, the middle groove plates and the lower groove plates. The special formwork can be repeatedly used in the installing process. Meanwhile, the structure is simple and reliable, and using is flexible and convenient. The work efficiency is improved in a multiplied manner. Wood, steel plates and foam plastic resources are saved, the problem of environment pollution is avoided, and the special formwork can be widely applied to the field of concrete construction.
