Abstract

The invention discloses a steep inclined shaft slip form system and a cast-in-place concrete lining construction method, and belongs to the technical field of steep inclined shaft concrete construction. The construction method comprises the steps that construction preparation is carried out, and specifically, a winch, a prefabricated separation type steel form, and a lifting vehicle which are needed by construction are prepared; form body mounting is carried out, specifically, the separation type steel form is aligned and folded according to a rabbet and then is lowered to an inclined shaft, and the lifting vehicle is adjusted and placed in the separation type steel form to be adjusted; chute mounting is carried out, and specifically, a chute at the customized pouring device communicates with a chute pouring window preset on the separated steel form; and concrete pouring is carried out, and specifically, concrete is poured into the concrete pump pouring window by using a concrete pumpto fill a gap between the separation type steel form and the inclined shaft; and chute pouring is carried out while concrete pouring is carried out, and a lifting trolley is lifted through a winch toconvey workers to conduct quality inspection on a poured section. Inner wall pouring of the steep inclined shaft is completed through the above steps, maintenance is carried out through a spraying device, and the service life of the inclined shaft is prolonged.

Description

technical field [0001] The invention belongs to the technical field of concrete construction for steeply inclined shafts, in particular to a sliding form system for steeply inclined shafts and a construction method for cast-in-situ concrete lining. Background technique [0002] Inclined shafts are used as auxiliary tunnels for extra-long tunnels. With the development of society, there are more and more inclined shafts. Inclined shafts can not only increase the working surface for the construction of the main tunnel, but also serve as a temporary or permanent ventilation channel during the construction of the main tunnel. Multi-directional closure of the construction lead to improve construction accuracy. [0003] In the process of concrete construction, the construction must be carried out with one plate followed by one plate and two linings, and the trolley can only be moved when the concrete is completely solidified, so the slip-form construction cannot meet the requiremen...
