Problems solved by technology
This kind of side foundation is prone to displacement or collapse after construction, and the stability of the side foundation is poor
And this kind of side foundation also makes some of the outer steel frame and inner steel frame buried in the side foundation concrete exposed, which makes the outer steel frame and inner steel frame easy to oxidize
In addition, in the construction process of the existing tunnel concrete wall, it is difficult to control the amount of concrete in the pouring area on the right side, resulting in poor firmness of the concrete after construction and short service life

Embodiment Construction
[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0034] Examples, see Figure 1-Figure 11 As shown, the base-stiffening sideform linkage system includes an inner steel frame 14 and an outer steel frame 12, and also includes a pouring formwork 10 detachably and fixedly connected by several steel frame plates;
[0035] On the side slope of the foundation of the base, a ladder-like step slope wall 24 is dug, and a layer of mud cloth 20 is laid on the wall of the step slope wall; the inner layer steel frame is arranged along the wall of the step slope wall, The outer layer steel frame is vertically arranged on the outer side of the inner layer steel frame, and the pouring formwork is vertically arranged on the outer side of the outer layer steel frame, thereby forming the right pouring area 18 between the pouring formwork and the mud-proof cloth; Several anti-rust mechanisms 23 are arranged between the s...

The invention relates to the technical field of side foundation construction, in particular to a base layer stiffening side formwork linkage system and a construction method thereof. A side foundationis good in stability and not prone to moving and collapsing, the anti-rust effect on an outer-layer steel frame and an inner-layer steel frame is good, and concrete is easy to pour, stir and controlin the pouring process. The base layer stiffening side formwork linkage system comprises the inner-layer steel frame, the outer-layer steel frame and a pouring formwork; a ladder-shaped ladder slope-wall wall is dug in the foundation side slope of a base layer, and a layer of mud-separating cloth is laid on the wall face of the ladder slope-wall wall; and the inner-layer steel frame is arranged along the wall of the ladder slope-wall wall, the outer-layer steel frame is vertically arranged on the outer side of the inner-layer steel frame, the pouring formwork is vertically arranged on the outer side of the outer-layer steel frame, and thus a right-side pouring area is formed between the pouring formwork and the mud-separating cloth.
Description
technical field [0001] The invention relates to the technical field of side foundation construction, in particular to a base-stiffened side form linkage system and a construction method thereof. Background technique [0002] The side base on the stiffening side of the existing base is generally directly poured a concrete sill on the stiffening side of the base to form the side base. This kind of side foundation is prone to displacement or collapse after construction, and the stability of the side foundation is poor. And this kind of side foundation also makes some of the outer steel frame and inner steel frame buried in the side foundation concrete exposed, which makes the outer steel frame and inner steel frame easy to oxidize. In addition, in the construction process of the concrete wall of the existing tunnel, it is difficult to control the amount of concrete in the pouring area on the right side, resulting in poor firmness of the concrete after construction and a short ...
