The implementation principle of the double-sided wall construction system of the storage ring tunnel comprises the steps of firstly completing excavation of a foundation pit, paving three groups of sliding rails 1 at preset positions, fixing the positions of the sliding rails 1, installing all components to obtain the double-sided wall construction system of the storage ring tunnel, exerting force on an outer side forming template 3 through a telescopic diagonal brace 7 by an advance and retreat unit 8, directly exerting force on an inner side forming template 4 by an inner driving unit 9, enabling the outer side forming template 3 and the inner side forming template 4 to be in place, installing a sealing end plate 5 to form a pouring cavity with an opening at the top, pouring concrete into the pouring cavity at the moment, vibrating and curing until the concrete is solidified, removing the sealing end plate 5, exerting force on the outer side forming template 3 through the telescopic diagonal brace 7 by the advance and retreat unit 8, enabling the outer side forming template 3 to retreat by the inner driving unit 9 to directly exert force on the inner side forming template 4, exerting force on a supporting seat 2 to enable the supporting seat 2 to slide along the track of the sliding rails 1 and driving the outer side forming template 3 and the inner side forming template 4 to slide to the next construction site, and repeating the steps until the wall is completed.
In a second aspect, an embodiment of the present application discloses a method for constructing a double-sided wall of a storage ring tunnel, where the system for constructing a double-sided wall of a storage ring tunnel disclosed in the first aspect of the present application includes:
S1, excavating a foundation pit;
s2, paving the sliding rails 1, namely paving three groups of sliding rails 1 at preset positions, and fixing the positions of the sliding rails 1;
S3, assembling a construction system, namely installing all components to obtain a double-side wall construction system of the storage ring tunnel;
S4, positioning the molding template, namely, a driving and reversing unit 8 applies force to the outer molding template 3 through a telescopic diagonal brace 7, an inner driving unit 9 directly applies force to the inner molding template 4, so that the outer molding template 3 and the inner molding template 4 are positioned, and then a sealing end plate 5 is arranged to form a pouring cavity with an opening at the top;
s5, pouring concrete into the pouring cavity, vibrating and curing until the concrete is solidified;
S6, mold withdrawing, namely removing the sealing end plate 5, then applying force to the outer molding template 3 by the advance and retreat unit 8 through the telescopic diagonal brace 7, so that the outer molding template 3 is withdrawn, and simultaneously applying force to the inner molding template 4 by the inner driving unit 9 directly, so that the inner molding template 4 is withdrawn;
And S7, sliding the system, namely applying force to the supporting seat 2 to enable the supporting seat 2 to slide along the track of the sliding track 1, driving the outer side forming template 3 and the inner side forming template 4 to slide to a next application station, repeating the steps S4-S6, and performing roughening treatment on the concrete joint before concrete pouring construction until the construction of the wall bodies on two sides is completed.
It should be noted that, the construction system of the single-side wall body of the storage ring tunnel disclosed by the application can have one or more construction starting points, namely, after calculation, the construction system disclosed by the application can be applied to the multi-point simultaneous construction on the whole annular storage ring tunnel, and finally, the whole storage ring tunnel is formed by enclosing.
By adopting the construction method to construct the double-side wall body of the storage ring tunnel, the advance and retreat unit 8 can be matched with the telescopic diagonal brace 7 and the fixed rod 6 to realize the advance and retreat of the outer forming template 3, and the inner driving unit 9 can realize the advance and retreat of the inner forming template 4, so that repeated disassembly of the forming templates is avoided, the occupied time of hoisting equipment is reduced, and the use cost of the hoisting equipment in the construction process is reduced while the construction time of the wall body is shortened.
The above embodiments are not intended to limit the scope of the application, so that the equivalent changes of the structure, shape and principle of the application are covered by the scope of the application.
