The concrete pile with sharp head

Technical characteristics:
1, The sharp head of concrete conical pile is connected with the pile body as a whole when the pipe pile is formed. The mate and technology are the same, and the strength is above C80.
2, The concrete conical solid pile tip is able to block the connection between the inner hole of the pipe pile and the outside.It can prevent erosion objects from infiltrating into the inner hole from the lower end of the pile and eroding the inner wall of the pipe pile with poor compactness, so as to avoid the problem of two-way erosion inside and outside.
Role:
The concrete pile with sharp head plays an important role in ensuring the quality of pile foundation under some special geological conditions:
1, In the thick sand layer, The concrete pile with sharp head has strong penetration power and can enter deeper rock stratum.
2, In the bearing layer,there are strong weathered rock which is easy to soften with water。The concrete pile with sharp head can prevent water from infiltrating into the lower rock and soil layer of the pile end from the inner cavity of the pipe pile and reduce the influence to the bearing capacity.
Application comparison:
1, The real situation of Capital Iron and Steel Plant Project: the traditional pipe pile can not pass through the dense medium sand layer, and there are corrosion resistance problems, which can not meet the design requirements; The concrete pile with sharp head has the advantage of better penetration power and better tightness. Therefore, Shougang Design Institute decided to put the concrete pile with sharp head of Dadi brand into use in Caofeidian Project.
2, Fuzhou Tianjun Lanshuiwan Project: the cross pile tip welded with traditional steel plate was difficult to pass through the dense sand layer, and the pile was badly damaged;After using the concrete pile with sharp head , it could pass through the dense sand layer smoothly, and the rotten pile are less, which could meet the design requirements.
