Abstract
The utility model discloses an anti-frost-heaving steel-made slant-wall well for reducing or eliminating tangential frost heaving force on the well walls due to high underground water level in cold areas and frozen soil in winter. The slant-wall well comprises a well wall and an anti-frost-heaving protection layer, wherein an angle of 85 to 91 DEG is formed between the well wall and the well bottom; and the anti-frost-heaving protection layer comprises, from inside to outside sequentially, asphalt felt, polystyrene board, glass fiber cloth, and slag. Alternatively, an angle of 85 to 91 DEG can be designed between the well wall above a frost line and the frost line. The above design scheme can decompose the tangential frost heaving force generated by the frozen soil on the well wall so as to effectively obviate the occurrence of cracks in the joints of the well body and the pipelines due to the tangential frost heaving force after the soil is frozen, thereby ensuring the security and stable operation of underground pipe network and lowering the production cost.
Description
One, technical field
It is a kind of steel well that is used to protect the critical facility of valve, hydrant, measuring instrument etc. that the utility model relates to.
Two, background technology
The present this steel well that is used to protect critical facilitys such as valve, hydrant, measuring instrument, its design is the borehole wall perpendicular to the shaft bottom.When this steel well used under the lower and groundwater table conditions of higher in temperature, because the area is cold, groundwater table is higher, groundwater table was positioned at more than the frost line, and after the water in the soil freezed, volume increased, soil to around expand.Shaft steel casing outside soil produces horizontal thrust to it in the expansion process, because the well body can not impact the well body for symmetrical therefore horizontal thrust, the inboard frozen soil that joins with the borehole wall then can produce tangential frost-heave force to the borehole wall.Because the borehole wall is perpendicular to the shaft bottom, pipeline is positioned at below the frost line, not freezed influences, therefore pipeline can not change because of tangential frost-heave force, and the well body can integral body be moved vertically upward owing to be subjected to the influence of tangential frost-heave force, in case between pipeline and the steel well during being connected power and can't overcoming tangential frost-heave force of welding position, the welding position will produce breach and cause network of underground to leak, and cause pipe network normally to move.Because it is underground that leak source is positioned at, detect, maintenance is all very difficult, pipe network pressure sealing difficulty is big, overhaul not only time-consuming, effort, and the increase cost of production, and waste water resource again has a strong impact on the water supply security of pipe network.
Three, summary of the invention
Goal of the invention of the present utility model is to provide a kind of anti-freeze expansion shaped steel system skew wall well at the problems referred to above, is used to reduce or eliminates cold district groundwater table height, winter frozen soil to tangential frost-heave force that the borehole wall produced.
The technical scheme that above-mentioned purpose adopted is: a kind of anti-freeze expansion shaped steel system skew wall well is made of the borehole wall and anti-freeze expansion topping, and the borehole wall and shaft bottom are 85 °～91 ° angles; The anti-freeze expansion topping is respectively felt paper, benzene plate, glass wool cloth, slag from inside to outside.
Another embodiment of the present utility model is that the frost line above borehole wall and frost line are 85 °～91 ° angles, and the borehole wall below the frost line is vertical with the shaft bottom; The anti-freeze expansion topping is respectively felt paper, benzene plate, glass wool cloth, slag from inside to outside.
Adopt the good effect of technique scheme: the angle of the borehole wall and shaft bottom formation and anti-freeze expansion topping can decompose frozen soil to tangential frost-heave force that the borehole wall produced in the technique scheme; effectively avoided well body and pipeline junction behind the soil freezing to tear phenomenon because of what tangential frost-heave force took place; guarantee network of underground safety, even running, reduced cost of production.
