UNDERGROUND STRUCTURE CAPABLE OF ADJUSTING HEIGHT
To provide an underground structure capable of adjusting a height, in adjusting a height after an installation, in which: a housing to be lifted up and down can be rotated without removing sediment around the housing to be lifted up and down; a housing to be lifted up and down does not settle due to vibration and the like; a manual installation work is possible without using a lifting device such as a jumbo, and which can easily cope with a sloped road.SOLUTION: A cast housing 22 with female screws including a lid receiving frame portion 23 is screwed with an upper part of a cast housing 21 with male screws whose flange portion 21a is fixed to a manhole side block 20. A pitch of screw threads P, Q of the housing 21 with male screws and the hosing 22 with female screws are formed to be large. A wedge 24 is driven into a clearance R between the upper part of the housing 21 with male screws and the hosing 22 with female screws. An earth pressure receiving cylindrical body 25 is disposed at an outside of the hosing 22 with female screws.SELECTED DRAWING: Figure 1
【課題】 設置後の高さ調整に際し、昇降筐体の周囲の土砂を除去せずに昇降筐体の回動を行うことができ、また、昇降筐体が振動等により沈下することがない高さ調整可能な地下構造物を提供する。また、ユンボ等の吊り上げ機具を用いずに手作業で設置工事を行うことができると共に、勾配のある道路用にも対応容易な高さ調整可能な地下構造物を提供する。【解決手段】 フランジ部２１ａをマンホール側塊２０に固定した鋳物製の雄ねじ筐体２１の上部に蓋受枠部２３を備えた鋳物製の雌ねじ筐体２２を螺合し、前記雄ねじ筐体２１と雌ねじ筐体２２のねじ山Ｐ，Ｑのピッチを大きく形成する。雄ねじ筐体２１の上部と雌ねじ筐体２２間の隙間Ｒに楔２４を打ち込み、雌ねじ筐体２２の外側に土圧受け筒体２５を配置する。【選択図】図１
