Description

A kind of subway station of Curve Pipe Jacking supporting and protection structure enlarging shield-tunneling construction
Technical field
The utility model relates to a kind of subway station extending shield-tunneling construction, belongs to underground construction trenchless technology field.
Background technology
Along with China's economic development and the urbanization level improve, traffic problems have become the key issue of restriction urban development, need solution badly.Shield method subway, as the important component part of Urban Public Transportation Network, plays huge effect to the modernization level in alleviation traffic jam, raising urban development speed, lifting city.But because shield structure zone distance is short, station quantity is many, shield structure could transition after often must waiting for station completion, cause the improper driving time too much, Suporting structure utilization rate is on the low side, cause construction delay phenomenon, increase construction cost, therefore shield structure station is the principal element of restriction subway work cycle and cost.
At present, the conventional construction method of subway station comprises cut and cover method, cap excavation method and hidden construction process etc.Cut and cover method is applicable to broad construction plant, and large to urban life interference, block traffic for a long time, noise and vibrations etc. are on the impact of environment.Cap excavation method stud construction joint is more, need carry out waterproofing work, and be unearthed inconvenient, work efficiency is low, and speed of application is slow; The shallow mining method duration is longer, and settlement of stratum is comparatively large on the impact of adjacent building safety, and construction risk is large, and construction costs is also very high.Because above-mentioned construction method needs not stop to carry out waterproofing work in work progress, and inner supporting and protection structure is reinforced concrete structure, in water rich strata, the space of reinforced concrete structure inside produces capillarity, formation water easily permeates and causes subway station inner moist, and formation water can the reinforcing bar of slowly eroded reinforced concrete inside configuration, there is the problem of the less and water-tight poor performance of structural strength in the subway station of therefore said method construction.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and provide a kind of Curve Pipe Jacking supporting and protection structure to extend the subway station of shield-tunneling construction, this subway station has the advantage that structure is simple, intensity is high, supporting is safe and reliable and water-tight performance is good, is applicable to the area of water rich strata.
Realizing the technical scheme that the utility model object adopts is, a kind of subway station of Curve Pipe Jacking supporting and protection structure enlarging shield-tunneling construction, at least comprise vault lining cutting, side wall lining cutting, base plate, brace foundation, mid-board and platform, mid-board is located on brace foundation, the top of mid-board is connected with shield duct piece top flat, peripheral support structure is provided with between subway station and stratum, described peripheral support structure by more than 2 along the axial parallel arrangement of shield tunnel and inside built concrete curve supporting pipeline and formed, the two ends of each curve supporting pipeline connect shield duct piece top flat and shield duct piece egative film respectively, vault lining cutting and side wall lining cutting to be all positioned at inside peripheral support structure and with peripheral support anatomical connectivity, brace foundation is located on shield duct piece egative film, base plate to be positioned at above shield duct piece egative film and to be connected with shield duct piece egative film.
Described curve supporting pipeline is provided with injected hole, the grouting and reinforcing district sealing that the gap between adjacent two curve supporting pipelines is formed by sealing slurries.
Two freezing pipes be interconnected are provided with in described curve supporting pipeline, two freezing pipes are symmetrically distributed in the two ends of place curve supporting internal diameter of the pipeline and fit with the inwall of place curve supporting pipeline, and the gap between adjacent two curve supporting pipelines is by freezing the consolidation by freezing district sealing formed.
Vault lining cutting and side wall lining cutting are formed by the waterproofing course set gradually from outside to inside, template and reinforced concrete structure, and reinforcing bar binding is in template.
As shown from the above technical solution, the subway station of the Curve Pipe Jacking supporting and protection structure enlarging shield-tunneling construction that the utility model provides, the basis of the inner lining cutting in existing subway station increases peripheral support structure, peripheral support structure by more than 2 along the axial parallel arrangement of shield tunnel and inside built concrete curve supporting pipeline and formed, the two ends of each curve supporting pipeline connect shield duct piece top flat and shield duct piece egative film respectively, form an entirety, the lifting surface area that the curve-like of curve supporting pipeline adds pipeline is simultaneously stressed more reasonable, there is good resistance to compression and anti-deformation, vault lining cutting, side wall lining cutting is positioned at inside peripheral support structure, peripheral support structure plays a good protection to vault lining cutting and side wall lining cutting, concrete has been built in curve supporting pipeline, the concrete rigidity of structure is large, good stability has good durability simultaneously.
Curve supporting pipeline is provided with injected hole, for the area that groundwater pressure is larger, form grouting and reinforcing district by injected hole to the gap slip casting between adjacent two curve supporting pipelines, intensity between the pipe of increase Curve Pipe Jacking, plays good waterproof effect simultaneously; Be provided with two freezing pipes be interconnected in curve supporting pipeline, for the area that grouting consolidation effect is poor, can inject cryogen in freezing pipe, cryogen is freezed surrounding formation by freezing pipe, plays the soil body between sealing and reinforcing pipe.
The utility model provides vault lining cutting and side wall lining cutting to form by waterproofing course, template and the reinforced concrete structure set gradually to interior (subway station is inner) from outer (stratum), waterproofing course plays the effect of secondary waterproof, the rigidity of structure that template, reinforcing bar and pouring concrete are formed is large, and good stability has good durability simultaneously.
