Title: Engineering Practice of High Pressure Jet grouting & Bored Cast-in-place Pile
Abstract: The method of high pressure jet grouting bored cast-in-place pile not only can solve the problem of the settling thickness at the bottom of bored cast-in-place,but also reinforcing the bearing capacity on pile tip and reducing the length of pile.Meanwhile it has the advantages of construction convenience,dependable quality,short work periods,less investment and little environmental pollution.Therefore,the method is the most suitable method during the construction of high buildings on the condition of the soft soil foundation.Based on the background of an engineering example and the code of pile foundation,the design method of rigid-flexible pile foundation which was formed by bored cast-in-place pile and high pressure jet grouting is presented by this paper.Moreover,the bearing capacity and settlement of composite pile foundation is in accordance with the testing results.Therefore,this method may be popularly used in the soft soil of coastal areas.
