Foundation pit retaining wall shotcreting and anchoring method
The invention discloses a foundation pit retaining wall shotcreting and anchoring method, belongs to the field of foundation pit construction, and aims to improve the construction quality of foundation pit retaining wall shotcreting and anchoring. Comprising the following steps: 1) transversely laying an upper guide rail on a pit top along a slope and installing an upper vehicle, and laying a lower guide rail on a pit bottom and installing a lower vehicle; (2) an inclined guide rail loaded with a spraying body is installed; (3) connecting a quick-setting concrete jet orifice to a jet pipe on a jet body, and stopping a jet device at the bottom end of the inclined guide rail; (4) moving the jet body to the initial position of the jet anchor of the side slope; (5) the spraying body sprays concrete from the bottom end of the inclined guide rail until moving to the top end of the inclined guide rail at a constant speed; (6) the spraying body slides down to the bottom end of the inclined guide rail from the top end of the inclined guide rail; (7) the upper vehicle and the lower vehicle move forwards by a step pitch along the corresponding guide rails; and repeating the steps (5), (6) and (7) until one-time side slope shotcrete anchoring is completed. In the longitudinal spraying process, the spraying body moves at a constant speed, and the transverse movement is the movement according to a set step pitch, so that the uniformity of the spraying thickness at each position is ensured, and the construction quality is improved.
本发明基坑护壁喷锚方法，属于基坑施工领域，目的是提高基坑护壁喷锚施工质量。包括1)沿着边坡横向在坑顶铺设上导轨并安装上车，坑底铺设下导轨并安装下车；2)安装载有喷射本体的斜导轨；3)将速凝混凝土喷射口接至喷射本体上的喷射管，将喷射装置停靠于斜导轨底端；4)移动喷射本体处于边坡的喷锚起始位置；5)喷射本体由斜导轨的底端开始喷射混凝土直至匀速移动到斜导轨的顶端停止；6)喷射本体由斜导轨的顶端下滑至斜导轨的底端；7)上车和下车沿对应导轨向前移动一个步距；重复步骤5)、6)和7)直至完成一次边坡喷锚。纵向喷射过程中喷射本体匀速运动，横向移动是按设定步距移动，保证了各处喷射厚度的均匀性，提高了施工质量。
