Description
Technical field
The present invention relates to shield tunnel technology, specifically a kind of shield tunnel plug-in conduit grooving structure and fixing means thereof.
Background technology
Shield method is the Fully-mechanized construction method of one in shallow mining method, it is advanced in ground by Shield-type machinery, prevent toward caving in tunnel by shield structure shell and section of jurisdiction supporting surrounding country rock, carry out soil excavation at excavation face front topping machanism simultaneously, transport outside hole by unearthed machinery, by jack in rear pressurization jacking, and assembled precast concrete section of jurisdiction, form a kind of mechanized construction method of tunnel structure.
The advantage of shield tunnel be safe and efficient, driving speed is fast; The propelling of shield structure, be unearthed, the overall process such as assembled lining cutting can realize automated job, construction labour intensity is low; Do not affect traffic above-ground and facility, do not affect the facilities such as underground utilities simultaneously; Do not affect shipping when passing through river course, not by the weather influence such as season, wind and rain in construction, in construction, there is no noise and disturbance; In soft water bearing ground, build the larger long tunnel of buried depth often possess skills and the superiority of economic aspect.But Shield-type machinery is expensive and with strong points, to each tunnel with constructing tunnel, all needs to manufacture and design specially according to engineering geology, hydrogeological conditions and structure section size, generally can not reuse in other tunnels simply; And difficulty of construction is larger when tunnel radius of curvature is too small or top, tunnel earthing is too shallow; Simultaneously in rich yew Soft Soil Layer, ground settlement is difficult to control, very high to lining cutting integral waterproofing technical requirements; To subaqueous tunnel, when earthing is too shallow, construction is also safe not; And when adopting full pneumatic process drainage and good ground, execution conditions are poor, require higher to labour protection.
It is fix support by setting expansion bolt that shield tunnel gut line and equipment install traditional form of construction work, expansion bolt boring is installed and not only can destroys liner structure, affect it stressed and cause percolating water, and drilling construction will produce a large amount of dust and noise, cause severe construction environment, require very high to construction precision simultaneously, redrilling is needed when adjustment and change support installing position, and expansion bolt does not have a dismoutability, serious inconvenience is brought to later stage operation maintenance, add maintenance cost, and expansion bolt can produce loosening under dynamic load and seismic loading, affect anchored force.
Summary of the invention
Technical problem to be solved by this invention is, how under the condition not destroying reinforced concrete structure, improves tunnel integral waterproofing performance and accomplishes to bear certain dynamic load and seismic load; How to simplify erection procedure, reduce the installation time, save integrated engineering expense; How to expand range of choice, make it be applicable to multiple different requirement; How to reach safe installation, noiselessness, friction, free of contamination object; How to make operation maintenance more convenient, meet the equal replaceable of all spare and accessory parts, more convenient maintenance.
In order to solve above technical problem, the invention provides a kind of shield tunnel plug-in conduit grooving structure, comprise hangers, bolt, pad, nut, segment bolt and section of jurisdiction, also comprise grooving and teeth groove, section of jurisdiction is reserved with fastening screw, hangers is the metallic sheet-like formation that one section of circular arc and a straight flange are connected to form, hangers is provided with installation circular hole, hangers uses segment bolt and nut to be fixed in the fastening screw of section of jurisdiction by its installation circular hole, grooving is both ends open, and there are three adjacent side close the square groove structure not exclusively closed with a side, the side not exclusively closed is parallel to square groove bearing of trend and is provided with rectangular installing port, three adjacent sealing surfaces form two boundary lines, the straight flange of wherein a boundary line place and the hangers of grooving welds together, and the straight flange of each hangers at least welds two groovings, included angle A between hangers place plane and the side folded by two boundary lines of grooving is 45-60 degree, tooth slot structure is identical with grooving structure, teeth groove is placed in grooving, and the rectangular installing port of teeth groove overlaps with the rectangular installing port consistency from top to bottom of grooving, pass through bolt, teeth groove and grooving are installed fixing by pad and nut at the rectangular installing port place of consistency from top to bottom.
The technical scheme that the present invention limits further is:
Aforementioned hangers straight flange welds two groovings, two nuts installed by each bolt, ensure to install and stablize firmly; Included angle A between hangers place plane and the side folded by two boundary lines of grooving is 57 degree, as calculated for being conducive to most stressed and angle that is space utilization; Bolt is T-shaped bolt, and the straight flange of its bolt head can directly be stuck in teeth groove, and convenient installation, not easily loosens.
Further, the fixing means of a kind of shield tunnel plug-in conduit grooving structure is also provided, comprises following concrete steps:
Step one: when making shield duct piece, fastening screw is reserved near sheet angle place in the edge of every sheet shield duct piece, at least reserved four the fastening screws of every block shield duct piece;
Step 2: a boundary line place in two boundary lines form adjacent for grooving three sealing surfaces and the straight flange of hangers weld together, included angle A between hangers place plane and the side folded by two boundary lines of grooving is 45-60 degree, and the straight flange of each hangers welds at least two groovings;
Step 3: teeth groove is inserted in grooving, and the direction of rectangular installing port is consistent, uses bolt, pad and nut teeth groove and grooving to be fixed together;
Step 4: hangers is arranged in the fastening screw of section of jurisdiction by segment bolt and nut.
Fastening screw in abovementioned steps one is the one of hoop hole, axial hole or upright opening.
The welding method adopted in abovementioned steps two is the one of gas shielded arc welding, plasma arc welding (PAW) or Laser Welding
The invention has the beneficial effects as follows:
