城市轨道交通设施三维空间权利确定方法

Confirmation Method of Urban Rail Transit Real Estate Spatial Rights in Three-dimensional Space

城市轨道设施等地下构建筑物日益增多,传统的二维不动产确权方法已不适用于地表、地下设施权属不一致的情况,亟需引入三维空间下不动产建设用地使用权确权方法,以保障地下空间设施权利得到清晰界定和合法保障。将二维空间的建设用地使用权延伸为三维空间的地上建设用地使用权、地表建设用地使用权、地下建设用地使用权;并针对有用地红线和无用地红线2种情形,分别提出利用实体界址点、平面界址点、空间界址点确定建设用地使用权权利界限方法及确权要素测量内容。该方法已成功应用于广州地铁7号线石壁站站台办理不动产权证书的实际确权过程中,实操性强且易于推广。

With the increase of underground structures such as urban rail facilities,the conventional confirmation method of urban rail transit real estate spatial rights in two-dimensional space is not applicable to the situation of inconsistent ownership of the surface and underground facilities.It is urgent to introduce the confirmation method of urban rail transit real estate spatial rights in three-dimensional space to ensure that the rights of underground space facilities are clearly defined and legally protected.Rights to use construction land in two-dimensional space is extended to rights to use construction land(above),rights to use construction land(surface)and rights to use construction land(underground)in three-dimensional space.As to the situation whether there is boundary line or not,it is proposed to use contour points,plane boundary point and space boundary point to define the confirmation method of urban rail transit real estate spatial rights and the required measurement contents.This method has been successfully applied in the process of confirming the real estate spatial rights of platform in Shibi Station of Guangzhou Metro Line 7.It is practical and easy to popularize.
