摘要： PROBLEM TO BE SOLVED: To securely prevent the collapse of soil grains even in a subgrade apt to loosen and stabilize the subgrade, in a sealed type rectangular boring machine which constructs a conduit line of rectangular cross section.SOLUTION: A hood 7 having a length covering above a rotary cutter 5 is attached to a forward end surface of an outer shell 1, a filler supply pipe 8b with a check valve 8a for supplying a consolidation type filler A to be filled between the hood 7 and a subgrade G is arranged inside the hood 7, and a discharge port 8 of the consolidation type filler A is opened in a top face of the hood 7. When a rectangular boring machine is advanced, the rotary cutter 5 excavates the subgrade G while the hood 7 penetrates the subgrade G, and the subgrade G above the rotary cutter 5 immediately after excavation is immediately supported by the hood 7 before th subgrade G can be even collapsed. Accordingly, collapse can be prevented even in the subgrade G apt to loosen. Furthermore, since the consolidation type filler A is filled in a place in front of a barrier 3, the subgrade G can be early stabilized as compared with the case of a conventional rectangular boring machine.
摘要翻译：要解决的问题：即使在构成矩形横截面的导管线的密封式矩形钻孔机中，即使在易于使路基松动和稳定的路基中，也可以可靠地防止土壤塌陷。解决方案：具有长度覆盖在旋转切割器5上方的外壳1附接到外壳1的前端表面，填充物供给管8b配置有用于供应要填充在罩7和路基G之间的固结填料A的止回阀8a 罩7和固化填料A的排出口8在罩7的顶面开口。当矩形钻孔机前进时，旋转切割器5挖掘路基G，同时罩7穿过路基G 在挖掘之后立即旋转切割器5上方的路基G在路基G能够均匀折叠之前立即被罩7支撑。因此，即使路基G易于松动，也能够防止塌陷。此外，由于固结型填料A填充在阻挡层3前方的位置，所以与现有的矩形钻孔机相比，路基G能够较早地稳定。

摘要： PROBLEM TO BE SOLVED: To provide jacked-pipe moving equipment which horizontally moves a jacked pipe, suspended in an adit, to a starting position in a main vertical shaft in the state of placing it on a supporting base, and which prevents damage to an outer surface of the jacked pipe by eliminating friction associated with the movement of the jacked pipe during a pipe jacking operation.
SOLUTION: A traversing guide rail 4 for making the supporting base 6 traverse between a suspending position and a starting one, and an advance/receding guide rail 5 for making the supporting base 6 advance/recede between the starting position and a complete-pushing one are installed on a foundation trestle 3. The supporting base 6 is provided with a hook 6f which makes the supporting base 6 on the guide rail 5 disengageably engaged with the foundation trestle 3. When the jacked pipe moved to the starting position is pushed from the rear under the state of the placement of the jacked pipe on the supporting base 6, the jacked pipe is jacked while the supporting base 6 travels on the guide rail 5. Thus, since the jacked pipe is moved integrally with the receiving base 6 when jacked, damage to the outer surface of the jacked pipe is prevented by virtue of the absence of the friction.

摘要： PROBLEM TO BE SOLVED: To enable cutting even when a reconstruction device meets a steel collar and a pouring socket and prevent operation of an excavator from being stopped due to jacking of a new pipe even when jacking the new pipe to enable smooth reconstruction of a pipe. SOLUTION: A starting shaft and an arrival shaft are newly provided adjacent to respective inner sides of an existing manhole to be reconstructed. A freely running cutting machine provided with a plurality of rotary blades runs in the existing pipe from the starting shaft to cut the existing pipe and a connection member by the rotary blades. Filler is filled into a space in the existing pipe cut simultaneously with the cutting. The existing pipe after filling is crushed by the jacking type excavator, and the new pipe being a jacking pipe is jacked from the rear while excavating the existing pipe and filler to replace the existing pipe with the new pipe.
