Box type foundation device for controlling tunnel push-out type joint settlement and construction method
The invention discloses a box type foundation device for controlling tunnel push-out type joint settlement. The device comprises an upper cushion layer, a lower cushion layer and a plurality of hydraulic telescopic cylinders arranged between the upper cushion layer and the lower cushion layer; the telescopic end and the bottom end of each hydraulic telescopic cylinder are fixedly connected with the upper cushion layer and the lower cushion layer through inclined supports respectively; and all the hydraulic telescopic cylinders are connected in series through a hydraulic pipe. The invention further discloses a construction method for controlling the tunnel push-out type joint settlement based on the device. The box type foundation device for controlling the tunnel push-out type joint settlement is simple in structure and convenient to construct, and the situation that joint supporting is not stable due to differential settlement caused by insufficient bearing capacity of a foundation is compensated; and meanwhile, when joints are in butt joint, broken stones of the upper cushion layer in the box type foundation device are in a falling state, the butt joint process cannot be affected at all, the butt joint stability is guaranteed, and meanwhile, the butted joints can be stably supported.
本发明公开一种控制隧道推出式接头沉降的盒式基础装置，包括上垫层、下垫层及设在所述上垫层和下垫层之间的若干液压伸缩缸，每一所述液压伸缩缸的伸缩端和底端分别与所述上垫层和下垫层通过斜支撑固定连接；所有所述液压伸缩缸通过液压管串联；本发明还公开基于该装置的一种控制隧道推出式接头沉降的施工方法。本发明结构简单，施工方便，弥补了因基础的承载力不足出现差异沉降导致接头支撑不稳定的情况，同时在接头进行对接时，盒式基础装置中的上垫层的碎石处于落下的状态不会对接头对接的过程造成任何的影响，保证了对接的稳定性，同时确保对接后的接头能够被稳定的支撑起来。
