Vacuum preloading soft soil foundation device

HONG MINGZHEN

The invention discloses a vacuum preloading soft soil foundation device which structurally comprises a bottom plate, a supporting box, a cover plate and a storage groove, the upper end of the bottom plate is connected to the lower end of the storage groove in a welded mode, the inner side of the supporting box is fixedly connected to the outer side of the storage groove in an embedded mode, and the lower end of the cover plate is fixedly connected to the upper end of the storage groove. A guide ring in a supporting frame between a supporting plate and a connecting frame slides and extends in an abutting ring along with a sliding block on the outer side of a top plate, the guide ring pushes a guide ring and a clamping ring in a chuck to extend, an abutting column at the front end of a top frame is bent to clamp soil, an elastic block in a clamping plate makes contact with the soil, and an arc block abuts against an arc groove in the upper end of a pushing block for supporting; the arc-shaped grooves push the ejector rods to abut against the connecting plates for fixing, the storage groove is erected through the supporting frame, and the situation that the bottom plate inclines along with sinking of the soft soil, so that the corners of the surface of the sealing film crack, air enters the vacuum box, and the reinforcing effect of the soft soil foundation is reduced is prevented.

本发明公开了一种真空预压软土地基装置，其结构包括底板、支撑箱、盖板、储存槽，底板上端焊接连接于储存槽下端，支撑箱内侧嵌固连接于储存槽外侧，盖板下端固定连接于储存槽上端，将固定地基装置放置在土层内，挖开通道，使支撑板与连接架之间的支撑架内的导圈随顶板外侧的滑块在抵圈内进行滑动伸展，导圈推动卡盘内的导环与卡环进行伸展，使顶架前端的抵柱弯折卡住土壤，夹板内的弹块与土壤进行接触，使弧块抵住推块上端的弧槽进行支撑，弧槽推动顶杆抵住连接板进行固定，使支撑架将储存槽架起，防止底板随松软的土壤凹陷而形成倾斜，导致封闭膜表面边角发生开裂，空气进入到真空箱内，造成软土地基的加固效果被降低。
