Description
Technical field
The utility model relates to constructing metro tunnel technical fields, more specifically, it relates to which a kind of shield well side wall adds
Armpit every template node structure.
Background technique
In subway work, " shield construction " is used as a kind of advanced method for tunnel construction, has mechanical automation journey
Degree is high, speed of application is fast, ground disturbance is small, road traffic, ground surface environment is not interfered to influence the advantages that small, at present in China tunnel
Engineering field has obtained extensive utilization, and later shield tunnel specific gravity shared in China's field of traffic will be increasingly
Greatly.
Building the work that tunnel first has to carry out using shield construction is shield launching construction, if shield launching is constructed
It is not interior AT STATION carry out, it usually needs then shield machine is hung in again and originated in vertical shaft by a shield launching vertical shaft of first constructing
Carry out shield launching construction.Shield machine originate in vertical shaft originate on the track of bracket promote when not can be carried out tuning, and
Shield launching construction often carries out in having performed the vertical shaft soil layer that grouting and reinforcing or rotary churning pile are reinforced, and the resistance of driving is very
Greatly, thus shield launching construction be all the time shield construction tunnel heavy difficult point and risk point, be one in shield construction
A particularly important link, is often related to the success or failure of entire shield tunnel construction.
When carrying out shield launching construction in shield launching vertical shaft at present, shield launching is very important in subway work
Link needs manually or mechanically to cut in originating well construction portal glass fiber-reinforced polymer stake, cuts, portal longer with clearance time
Poor flatness, and the soil body collapses when originating and the risk of soil erosion is higher, and the waste of portal plugging material is serious.
To guarantee the structural strength of side wall in shield launching well construction and the soil body being avoided to collapse, need in side wall and basic bottom
Haunch angle is added at plate position.Haunch shuttering supporting is generallyd use, concrete is poured into template through maintenance and forms haunch angle.But
With template at currently used haunch, structural strength is lower, and fixation is unreliable, and template is easy to float, and applies to influence subway
Working medium amount.To guarantee that haunch template and the two sides side wall template of shield well ontology do not occur faulting of slab ends phenomenon, therefore, it is necessary to a kind of shields
Structure well side wall haunch every template node structure meets the demand of the shield launching vertical shaft of subway work.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of shield well side wall haunch templates
Node structure, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides the following technical solutions:
A kind of shield well side wall haunch every template node structure, including shield well ontology, haunch angle, template, perpendicular back cord, horizontal back
There is haunch angle, be equipped with mould at the haunch angle of shield well ontology in stupefied and support system, the shield well body construction quadrangle
Plate, perpendicular back cord and horizontal back cord；At the haunch of shield well ontology be equipped with support system, support system by steel pipe, adjustable jack with
The disk buckle type scaffold upright bar of socket joint type is integral with fastener locking, and locking points no less than 3；The adjustable jack number at each armpit angle
Amount no less than 3, at the haunch of shield well ontology transom and two sides side wall transom by the way that transom is opened groove mode, and
With iron nail stickfast, template vertical keel and lateral keel stickfast are consolidated.
Further, the haunch angle is having a size of 750mm × 600mm and 650mm × 600mm.
Further, the template is 18mm thickness wood plywood, and perpendicular back cord is 100mm × 50mm lumps of wood, spacing is not more than
200mm, horizontal back cord are 100mm × 100mm lumps of wood, spacing 600mm.
Further, the haunch angle and each one of two sides wall junction, it is one intermediate.
Further, the quantity of the keyed end is 3 and respectively keyed end one, keyed end two and keyed end three.
In conclusion the utility model has the advantages that compared with prior art
Template, perpendicular back cord and horizontal back cord is arranged in the utility model at the haunch angle of shield well ontology, and sets at haunch
It sets and locks the integral support system formed with fastener by steel pipe, adjustable jack and the disk buckle type scaffold upright bar of socket joint type, with this
Connection structure enhances the structural strength of shield well side wall armpit Angle formwork and its supporter, realizes effectively support, support it is more secured,
Reliably, construction risk is reduced, stress is more effective, reasonable, and template is not easy to float, by template vertical keel and lateral keel stickfast
Gu to guarantee not occurring faulting of slab ends phenomenon with side wall at haunch, to guarantee the haunch template and two sides side wall template of shield well ontology
Do not occur faulting of slab ends phenomenon, ensure that subway work quality.
For the structure feature and effect for more clearly illustrating the utility model, come with reference to the accompanying drawing with specific embodiment pair
The utility model is described in detail.
