Grouting soil arch induction type pile-supported embankment
The invention relates to a grouting soil arch induction type pile-supported embankment. The embankment is characterized in that a plurality of rigid piles are buried in a soft soil layer, and an embankment filling layer is laid above the soft soil layer; a plurality of longitudinal main pipes are embedded in the embankment fill stratum, the bottom end of each main pipe is communicated with the top ends of a plurality of branch pipes, the branch pipes are obliquely arranged, the bottom end of each branch pipe is arranged above the top face of the corresponding rigid pile, each main pipe is located at the centroid of the range defined by all the rigid piles corresponding to the branch pipes connected with the main pipe, each branch pipe is of a hollow structure, and a plurality of liquid guide holes are evenly formed in the side wall of each branch pipe; and slurry injected from the main pipes flows out through the branch pipes and the liquid guide holes and is used for reinforcing the branch pipes and matrixes on the outer sides of the branch pipes. According to the grouting soil arch induction type pile-supported embankment, grouting enhancement can be conducted through the pipelines arranged in the embankment in advance, the soil arch effect is induced to be exerted, embankment loads are promoted to be transferred to the tops of the rigid piles, stable soil arches can be formed as soon as possible, and the pile-soil load sharing ratio is increased, so that the high bearing characteristic of the rigid piles is fully exerted.
本发明是一种注浆土拱诱导式桩承式路堤，若干刚性桩埋设在软土层内，软土层上方铺设路堤填土层；路堤填土层内埋设若干纵向主管，每根主管的底端与若干支管的顶端连通，支管倾斜设置，且每根支管的底端分别设置在对应刚性桩顶面上方，每根主管位于其所连支管对应全部刚性桩所围范围的形心处，每根支管为中空结构且侧壁均匀开有若干导液孔；由主管注入的浆液经由支管和导液孔流出用于对支管和支管外侧基质增强加固。该种注浆土拱诱导式桩承式路堤，能够通过路堤中预先布置的管路进行注浆增强，诱导土拱效应发挥，促进路堤荷载向刚性桩顶部转移，有助于尽快形成稳定土拱，提高桩土荷载分担比，从而充分发挥刚性桩的高承载特性。
