Method for installing tension member of anchoring structure of anchoring cylinder and construction device used in method
The invention relates to a method for installing a tension member of an anchoring structure of an anchoring cylinder and a construction device used in the method in the field of rock-soil anchoring engineering. The method comprises the following steps of firstly, constructing a hollow steel pipe as the anchoring cylinder in a rock-soil body, then constructing a horizontal or inclined lateral steel pipe in the rock-soil body between an anchored body and the anchoring cylinder, after the lateral steel pipe intersects with the side wall of the anchoring cylinder, the specific position of the intersection point of the lateral steel pipe and the side wall of the anchoring cylinder is determined by heating or cooling the front end of the lateral steel pipe and then detecting the change of a temperature field of the side wall of the anchoring cylinder, and forming a hole in the side wall of the anchoring cylinder, so that the anchoring cylinder communicates with the lateral steel pipe to form a tension member mounting hole, the construction device comprises a rack (1), the lateral steel pipe (2), a lateral steel pipe clamp (3), an insertion and extraction power device (4) and a temperature changing device (5). The method can accurately determine the position of the intersection point in rock soil, and is high in construction speed, high in safety degree, reliable in quality and low in manufacturing cost.
本发明涉及岩土锚固工程领域中的一种锚定筒锚固结构受拉构件安装方法及其所用的施工装置，该安装方法首先在岩土体中施工中空钢管作为锚定筒，然后在被锚固体与锚定筒之间的岩土体中施工水平或斜向的侧向钢管，在侧向钢管与锚定筒侧壁相交后，通过在侧向钢管的前端加热或降温，再检测锚定筒侧壁温度场的变化，以确定侧向钢管与锚定筒侧壁相交点的具体位置，在锚定筒侧壁上开孔，使锚定筒与侧向钢管连通，形成受拉构件安装孔，施工装置包括机架(1)、侧向钢管(2)、侧向钢管夹具(3)、插拔动力装置(4)、温度改变装置(5)五部分，该方法能在岩土中准确确定交点位置，施工速度快，安全度高，质量可靠、造价低。
