摘要： PROBLEM TO BE SOLVED: To provide a simple low-cost structure for preventing the lift of a manhole which dispenses with large-scale work, can also be easily applied to an existing manhole, and can surely prevent the manhole from being lifted due to a ground liquefaction phenomenon during an earthquake.
SOLUTION: In this structure for preventing the lift of the manhole 1, a manhole body 2 is buried like an erected pile so as to be used, for example, for detecting a sewerage pipe 5 as a buried pipeline, and connected to the sewerage pipe 5. A plurality of through-holes 11 which make an underground 10 side communicate with the side 200 of the manhole body 2 are formed at circumferential intervals in the side wall 2a of the manhole body 2; and a grouting material is solidified by being injected into the underground 10 side from the inside 200 of the manhole 2 via the through-holes 11, so that a ground improving structure 13 can be provided on the outer periphery of the side wall 2a of the manhole body 2.

摘要： PROBLEM TO BE SOLVED: To provide a surfacing prevention structure of a buried object capable of being easily applied also to the existing underground buried object by a low costed device without being required for any large scaled work with a very simple structure and preventing the incursion of earth and sand mixed water to the underground buried object other than emergency such as an earthquake or the like.
SOLUTION: The surfacing prevention structure of the buried object is so constituted that through-holes 12 and 13 communicating the underground 11 side with the inside of a manhole body 2 are formed in a side wall 2a of the manhole body 2 of a manhole 1 and that lid devices 14 permitting or cutting off the flowing of water between the underground 11 side and the inside 200 are provided in the through holes 12 and 13. The lid devices 14 are equipped with an outer cylinder 20 inserted into the through-holes 12 and 13, a pressure receiving plate 21 having cut-off efficiency and a claw member 22 interlocking the pressure receiving plate 21, and each lid device 14 is so constituted that the claw member 22 is fractured to make it secede from the outer cylinder 20 when the pressure difference between the underground 11 side and the inside 200 is in excess of a constant value, water in the underground 11 side can flow to the inside 200 through the outer cylinder 20 and that the circulation of water between the underground 11 side and the inside 200 can be cut-off by the pressure receiving plate 21 when the pressure difference is less than the constant value.

摘要： PROBLEM TO BE SOLVED: To provide a structure for preventing floating of an embedded body, which is implemented by an inexpensive device having a very simple structure and dispensing with large-scale construction work, applicable to an existing underground embedded body, and can prevent inflow of water mixed with sediment in normal times other than in an emergency such as an earthquake. SOLUTION: The structure for preventing floating of the embedded body is set up by forming through-holes 12, 13 in a side wall 2a of a manhole body 2 of a manhole 1 as the embedded body, so as to communicate between an underground 11 area and the interior 200 of the manhole body 2, and fitting cover members 14 into the through-holes 12, 13, for allowing or shielding water flow between the underground 11 area and the interior 200. Each cover member 14 is formed of an external cylinder 20 inserted into each of the through-holes 12, 13, and a main body 21 installed in the external cylinder 20. The main body 21 is broken when a pressure difference between the underground 11 area and the interior 200 is in excess of a predetermined value to allow water on the underground 11 area to flow into the interior 200 via the cover member 14, whereas it maintains shielding of the water flow between the underground 11 area and the interior 200 when the pressure difference is equal to or below the predetermined value.
