Document Type and Number:
Japanese Patent JP2016102392
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a grout injection pipe with a ground settlement inspection device under a large civil engineering and construction structure deck slab which secures good installation workability and is excellent in operability and earthquake resistance.SOLUTION: A settlement inspection guide pipe 3 and an upper check valve device pipe 4 are incorporated side by side into a grout injection pipe 2 provided with check valve devices 5 installed at upper and lower ends. A settlement inspection device 7 with a settlement rod 8 incorporated therein in a vertically movable manner is disposed inside the settlement measurement guide pipe 3. The grout injection pipe 2 with a ground settlement amount inspection device is split into upper and lower parts at an arbitrary position, a lower pipe 2B of the grout injection pipe 2 is installed first, and then connection of an upper pipe 2A is allowed. In addition, a lower end of the settlement rod 8 is provided with an adjustable connection part 8g to a settlement board 12, which can be connected to the preset settlement board 12 afterwards.SELECTED DRAWING: Figure 1
