深基坑软土地基地源热泵直埋式换热管施工技术

Construction Technology of Direct-buried Heat-exchange Pipe of Ground Source Heat Pump in Soft Soil Foundation

绍兴市文化中心地源热泵直埋式换热管因节地要求,需在流塑状淤泥质软土地基中施工,施工难度较大。通过创新工艺施工,先浇筑操作垫层,再钻孔埋管,有效解决了软土地基钻机施工承载力不足、泥浆不能及时外运与施工交叉污染的难题。

Because of the limited space in Shaoxing City Culture Uenter, direct-buried heat-exchange pipe has to be constructed in soft soil foundations. Because of the great difficulty in the construction, a new method that construct the operation cushion first, and then to bury the pipes was adopted. This method has effectively solved the problem of lack of carrying capacity in the soft foundation and prevented cross contamination.
