It is first-class engineering that south water to north center line first phase is worn yellow engineering, wears the yellow tunnel list long 4.25km in hole, and rice surplus the buried depth 30 provides the shield machine driving by Germany extra large Rake company, assembles in vertical shaft, and the vertical shaft scale is big.Meet with deposits such as big boulder, ancient tree for handling tunneling process, set up air-lock behind the head sealed compartment, shield machine length increases 2.5m than raw footage, causes vertical shaft only to be left 0.5m and arranges for reaction frame.In view of can't adjusting the shield machine size, and vertical shaft is also by former design size excavation diaphragm wall.In the case, Construction unit thinks that the approach that solves has two: one: build a blind hole that is about 10m in the opposite direction that shield machine sets out, its two: diaphragm wall that vertical shaft has been started building cancels, and original position is rebuild after with enlarged diameter 2.5m, arranges for reaction frame.
For the scheme (scheme two) of vertical shaft enlarged diameter 2.5m, corresponding northern bank vertical shaft diaphragm wall interior diameter need be increased to 20.5m, not only will increase by 13% work shaft amount; And because northern bank vertical shaft is positioned at the Yellow River beach, and groundwater table is very high, less than 4m, deeply reach 76.6m and diaphragm wall is super from beach face, will increase the difficulty of engineering structures and waterproof greatly.
Build a blind hole scheme (scheme one) that is about 10m for the opposite direction of setting out at shield machine, the engineering precedent is arranged.Wear yellow engineering by this scheme implementation, construction investment not only increases greatly, and since the about 40m of position, blind hole buried depth, the groundwater table height, and if no special excavation equipment will be difficult to cavitation, the duration also will be incured loss through delay greatly, also be worthless.
Summary of the invention
The objective of the invention is to overcome above-mentioned existing disadvantages of background technology part, and a kind of shield structure of the reinforced concrete structure counter-force seat that sets out is provided.It is not increasing the shaft section area size and is not setting up under the condition of blind hole, solves shield machine and sets out, and has proposed the novel counter-force seat scheme that combines with shaft enclosure structure, only takies the space of 0.5m, has satisfied the needs that shield machine normally sets out.
The objective of the invention is to reach by following measure: the shield structure counter-force seat that sets out, it is characterized in that it comprises: the counter-force pedestal, ring-shaped bearing pier, ring-shaped bearing pier are arranged on the counter-force pedestal, and described counter-force pedestal and ring-shaped bearing pier are reinforced concrete structure.
In technique scheme, the other end of described counter-force pedestal has the vertical shaft liner, and the vertical shaft liner is between counter-force pedestal and diaphragm wall.
The present invention is simple in structure, and the ring-shaped bearing pier is used for accepting shield structure thrust, reaches liner, diaphragm wall by the counter-force pedestal again, bears jointly.
The present invention has satisfied shield machine and has installed in vertical shaft, sets out safely and normal tunneling construction needs.Following tangible project benefit and social benefit are arranged:
(1) avoid shield machine to lengthen 2m and caused a series of problems such as the vertical shaft scale enlarges, investment increase, construction delay, modification of contract:
(2) reaction frame of alternative routine satisfies shield machine and assembles in vertical shaft and the requirement of setting out, and is conducive to dwindle the vertical shaft scale, saves construction investment, can promote in similar engineering and use.
