Old road widening structure
The invention discloses an old road widening structure which comprises an existing retaining wall, an L-shaped check block is arranged at the top end of the existing retaining wall, the L-shaped check block comprises an upright short edge and a transverse edge connected with the lower end of the short edge, and the end, not connected with the short edge, of the transverse edge makes contact with an old road; the top surface of the short side is flush with the road surface, the width of the top surface is consistent with the width of the original earth shoulder, and the width of the top surface is not less than 50cm; the thickness of the transverse edge is 30-50cm, and the transverse edge exceeds the range of the fracture angle by not less than 50cm in the transverse direction; the height of the L-shaped check block is not larger than 2 m, and a broken stone hardcore is arranged at the bottom end of the L-shaped check block. According to the situation that the widening range does not exceed the existing retaining wall, the L-shaped check block is arranged at the top end of the existing retaining wall, widening treatment of an old road is effectively achieved, disturbance and damage to the existing retaining wall and an embankment in a conventional scheme are avoided, and the structure is convenient to construct, does not affect existing traffic, and is small in safety risk and low in engineering cost.
本发明公开了一种旧路拼宽结构，该结构包括既有挡墙，所述既有挡墙顶端设置有L型挡块，所述L型挡块包括直立的短边和与短边下端连接的横边，横边不与短边连接的一端接触旧路；短边的顶面与路面齐平，顶面宽度与原土路肩宽度保持一致，且顶面宽度不小于50cm；横边的厚度为30～50cm，在横向上超出破裂角范围不小于50cm；所述L型挡块的高度不超过2m，所述L型挡块底端设置有碎石垫层。本发明针对拼宽范围未超过既有挡墙的情况，通过在既有挡墙顶端设置L型挡块，有效实现对旧路的拼宽处理，避免常规方案需对既有挡墙、路堤的扰动和破坏，该结构施工便利，不影响现行交通，且安全风险小，工程造价较低。
