Abstract
The invention provides a general method for laying out and assembling wedge-shaped duct pieces. The general method comprises the following steps: step one, determining parameters of general wedge-shaped duct pieces and general wedge-shaped duct piece rings; step two, selecting a laying-out and assembling method; step three, during shield tunneling, carrying out fine turning on shield tunneling axes by utilizing the change of the general wedge-shaped duct pieces and the relative wedge-shaped volume in the vertical direction at different rotation angles. The general method has the beneficial effects that the general wedge-shaped duct pieces with only one manner can be used for a straight line section and also can be used for a curved section through the laying-out and assembling method of different wedge-shaped duct pieces, so that the manufacturing and assembling process of the duct pieces is simplified, the assembling quality of the duct pieces is improved, and the integrality of the duct piece rings is enhanced; meanwhile, through the adoption of the duct pieces with single type, the duct pieces are more convenient to store, transport, construct and manage.
Description
Technical field
The present invention relates to a kind of general wedge shape segment array assembling method.
Background technology
Shield tunnel is finally formed by pipe sheet assembling, and pipe sheet assembling generally adopts through seam assembling and two kinds of forms of staggered joint erection; But in common lining construction, the form of staggered joint erection is more single, and the anglec of rotation of section of jurisdiction is relatively fixing, limited to the fitting precision of Tunnel Design axis; The present invention relates to a kind of general wedge shape section of jurisdiction assembling method that can the existing straightway of matching shield tunnel has again the design axis of extra small radius of curvature section.
Summary of the invention
The present invention is intended to address the above problem, and a kind of general wedge shape section of jurisdiction assembling method that can the existing straightway of matching shield tunnel has the design axis of extra small radius of curvature section is provided.
For achieving the above object, the invention provides a kind of general wedge shape segment array assembling method, comprise the following steps:
Step 1, determine the parameter of general wedge shape section of jurisdiction and general taper pipe loop;
In step 3, shield driving, the variation of the general taper pipe loop level under use different rotary angle and the relative wedge shape amount of vertical direction, advances axis to finely tune to tunnel, guarantees the degree of accuracy of tunnel axis.
Described step 1 is the parameters such as total length according to shield tunnel, length of straigh line, extra small radius of curvature curved section length, determines the parameter such as internal diameter, external diameter, maximum wedge shape amount of width, thickness and the general taper pipe loop of general wedge shape section of jurisdiction; Each general taper pipe loop, by 6 wedge shape sections of jurisdiction, sequentially rearranges by A～F, determines the parameter of general taper pipe loop, determines the each point width parameter that general taper pipe loop is evenly distributed.
Described in step 1,6 wedge shape sections of jurisdiction of general taper pipe loop are connected in sequence, it longitudinally has 12 pairs of bolts hole, along general taper pipe loop even circumferential, distribute, every pair of bolt hole all becomes 30 ° with general taper pipe loop center, be that general taper pipe loop just has 12 installation sites along hoop, as according to the pattern of clock hour position, each installation site is called of general wedge shape section of jurisdiction the hour is installed; Corresponding 12 mounting points that have are assemblied into: A is positioned at that the order of 12 o'clock is arranged, the order of A while being positioned at 1 arranged, the order of A while being positioned at 2 arranged, the order of A while being positioned at 3 arranged, the order of A while being positioned at 4 arranged, the order of A while being positioned at 5 arranged, the order of A while being positioned at 6 arranged, the order of A while being positioned at 7 arranged, the order of A while being positioned at 8 arranged, the order of A while being positioned at 9 arranged, the order of A while being positioned at 10 arranged, the order of A while being positioned at 11 arranged; The relative wedge shape amount of the level that the different installation hours is corresponding and vertical direction, can be through calculating the parameter of general taper pipe loop 1～12.
Usefulness of the present invention is: the section of jurisdiction that makes to only have a kind of general wedge shape section of jurisdiction of form by different wedge shape segment arrays and assembling method, both can be used on straightway, also can be used on curved section, having simplified section of jurisdiction manufactures and assembled process, improve the assembled quality of section of jurisdiction, strengthened the globality of section of jurisdiction ring, simultaneously, adopt the single section of jurisdiction of model, make storage, transportation and the execution control of section of jurisdiction all more convenient.

The specific embodiment
As shown in Figures 1 to 5, the present embodiment provides a kind of general wedge shape segment array assembling method, and the shield tunnel with straightway and extra small radius of curvature curved section of take is example, comprises the following steps:
Step 1, according to this project tunnel total length 235m, two ends, tunnel are straightway, the right bent small radius section that interlude design mileage is R=248.5m, length is 217m, its lining segment adopts general wedge shape section of jurisdiction, the parameter of determining Huan Ji section of jurisdiction, section of jurisdiction is as follows: section of jurisdiction ring internal diameter 3900mm, external diameter 4460mm, every ring has 6 wedge shape sections of jurisdiction (A～F) to form, it longitudinally has 12 pairs of bolts hole, along section of jurisdiction even circumferential, distribute, all become 30 ° with center, section of jurisdiction, correspondingly, just there are 12 installation sites section of jurisdiction along hoop, each installation site is called an installation hour of section of jurisdiction.Corresponding section of jurisdiction ring wedge shape amount of different installation hours can be through calculating (center, A section of jurisdiction width is 997.1mm, other sections of jurisdiction can push away successively); Section of jurisdiction width 1000mm, section of jurisdiction thickness 280mm; It is 22mm that maximum wedge shape amount is encircled in section of jurisdiction, and the each point width that section of jurisdiction ring is evenly distributed is respectively 1011.0mm, 1010.7mm, 1009.6mm, 1007.8mm, 1005.5mm, 1002.9mm, 1000.0mm, 997.1mm, 994.5mm, 992.2mm, 990.4mm, 989.3mm, 989.0mm, 989.3mm, 990.4mm, 992.2mm, 994.5mm, 997.1mm, 1000.0mm, 1002.9mm, 1005.5mm, 1007.8mm, 1009.6mm, 1010.7mm, 1011.0mm.；
Table 1 different rotary angle section of jurisdiction wedge shape scale
In step 3, shield driving, the variation of the general taper pipe loop level under use different rotary angle and the relative wedge shape amount of vertical direction, advances axis to finely tune to tunnel, guarantees the degree of accuracy of tunnel axis.Fig. 4 and Fig. 5 are respectively the segment array figure of the present embodiment shield tunnel straight line and curved section, and at straightway, the main type-setting mode in section of jurisdiction adopts section of jurisdiction A=2:00, A=5:00, A=8:00, the combination of A=11:00 point position; At curved section, the main type-setting mode in section of jurisdiction adopts section of jurisdiction A=11:00, the combination of A=2:00 point position, and now wedge shape amount in section of jurisdiction is 15.65, to guarantee minimum correction radius 200m in progradation.
Although the present invention is disclosed by above embodiment, protection scope of the present invention is not limited to this, is not departing under the condition of the present invention's design, and the distortion that above each member is done, replacement etc. all will fall within the scope of claim of the present invention.
