Detailed description of the invention
Graphic for reference detailed description is used the tunnel segment structure with longitudinal twisted wire and transverse shearing force key of the present invention method to build shield tunnel.
First, the present invention longitudinal twisted wire to be inserted and is anchored on the basic conception in the section of jurisdiction assembled with the form of z shape as follows.
The length of longitudinal twisted wire is almost identical with the length arranging four longitudinal sections of jurisdiction.This is because longitudinal twisted wire is attached and grappling in units of four longitudinal sections of jurisdiction.Longitudinal twisted wire of one unit is four section of jurisdiction row, as illustrated by Figure 10.Figure 10 schematically illustrates the graphic of four longitudinal twisted wires about the basic section of jurisdiction A1 in the 4th tubulation sheet in the section of jurisdiction assembly of Fig. 9.
For example, longitudinal twisted wire that the twisted wire from the first row section of jurisdiction of Figure 10 inserts and fixed space district E2 starts by prestretching and is anchored in the twisted wire anchorage zone G1 in the 4th tubulation sheet.Basic section of jurisdiction A1 in all four longitudinal direction twisted wire traverse the 4th tubulation sheet.Now, through the starting point of four longitudinal twisted wires of the basic section of jurisdiction A1 in the 4th tubulation sheet and anchor point be different.The single longitudinal twisted wire started from first row section of jurisdiction is anchored in the basic section of jurisdiction A1 the 4th tubulation sheet.First this longitudinal twisted wire fixes the basic section of jurisdiction A1 in the 4th tubulation sheet.During basic section of jurisdiction A1 in fixing the 4th tubulation sheet in this way, longitudinal twisted wire from secondary series section of jurisdiction, the 3rd tubulation sheet and the 4th tubulation sheet sequentially.During basic section of jurisdiction A1 in not fixing the 4th tubulation sheet, longitudinal twisted wire of secondary series section of jurisdiction, the 3rd tubulation sheet and the 4th tubulation sheet is likely to the basic section of jurisdiction A1 not passing through in the 4th tubulation sheet.This is because the longitudinal twisted wire in secondary series section of jurisdiction it is practically impossible to through the loose basis section of jurisdiction A2 in the 5th tubulation sheet.
The longitudinal twisted wire started from secondary series section of jurisdiction is through the basic section of jurisdiction A1 the 4th tubulation sheet, and can be anchored in the 5th tubulation sheet when longitudinal twisted wire that only the basic section of jurisdiction A1 in the 4th tubulation sheet is inserted by the twisted wire from first row section of jurisdiction and fixed space district E2 starts subsequently is fixed.This is because only just can be anchored in the 5th tubulation sheet when the 4th tubulation sheet fixes.It addition, in order to the longitudinal twisted wire started from the 3rd tubulation sheet is anchored in the 6th tubulation sheet, it is necessary to fix the 5th tubulation sheet and the 4th tubulation sheet simultaneously.
All four longitudinal direction twisted wire is through all sections of jurisdiction, but only single section of jurisdiction is anchored in section of jurisdiction.Three longitudinal twisted wires of residue are through the basic section of jurisdiction A1 in the 4th tubulation sheet, and are sequentially anchored in next column section of jurisdiction subsequently.In other words, the grappling of longitudinal twisted wire making the adjacent test in basis, section of jurisdiction wall, described basis adjacent test wall is reinforced through three longitudinal twisted wires, and other basis adjacent test walls are repeatedly formed on boring direction.
As illustrated by Figure 10, four longitudinal twisted wires in the 4th tubulation sheet be from first row section of jurisdiction, longitudinal twisted wire of starting of secondary series section of jurisdiction, the 3rd tubulation sheet and the 4th tubulation sheet.That is, longitudinal twisted wire that twisted wire from first row section of jurisdiction inserts and fixed space district E2 starts is by prestretching and the twisted wire anchorage zone G1 that is anchored in the 4th tubulation sheet, and longitudinal twisted wire that the twisted wire from secondary series section of jurisdiction inserts and fixed space district E2 starts is by prestretching and the twisted wire anchorage zone G1 that is anchored in the 5th tubulation sheet.Similarly, longitudinal twisted wire that twisted wire from the 3rd tubulation sheet inserts and fixed space district E1 starts is by prestretching and the twisted wire anchorage zone G2 that is anchored in the 6th tubulation sheet, and longitudinal twisted wire that the twisted wire from the 4th tubulation sheet inserts and fixed space district E1 starts is by prestretching and the twisted wire anchorage zone G2 that is anchored in the 7th tubulation sheet.
In this way, longitudinal twisted wire that be inserted in the 4th tubulation sheet four penetrate in path be from first row section of jurisdiction, longitudinal twisted wire of starting of secondary series section of jurisdiction, the 3rd tubulation sheet and the 4th tubulation sheet, and be depending on the 4th tubulation sheet sequentially grappling simultaneously and fix the supporting member of the 5th tubulation sheet, the 6th tubulation sheet and the 7th tubulation sheet.This is the reason being referred to as the adjacent test in basis wall why of the basic section of jurisdiction A1 in the 4th tubulation sheet.
It addition, the section of jurisdiction in each row is arranged with the form of z shape, and and then because the shear stress caused by shear connector can increase.In addition, because the only one longitudinal direction twisted wire in four twisted wires is anchored and is fixed in each row, so the overlapping rigidity of longitudinal twisted wire can increase, and the structure being assembled is for being firm because of the differential pressure caused by soil pressure and earthquake, and serve as the adjacent test in the basis wall of section of jurisdiction for building continuously.Therefore, build and be easier to.It addition, the length of longitudinal twisted wire is the length making loss minimum and making tensile force maximum.
Although describe seven sections of jurisdiction for the ease of description, but as long as the number of section of jurisdiction is odd number, identical concept is applicable to five or seven sections of jurisdiction.
But, the first row section of jurisdiction of Figure 10, secondary series section of jurisdiction and the 3rd tubulation sheet are not provided with the adjacent test in basis wall.This is inevitable phenomenon, because section of jurisdiction and longitudinal twisted wire are to assemble with the form of z shape.
The assemble method of existing bolt method and the present invention performs in first row section of jurisdiction, secondary series section of jurisdiction and the 3rd tubulation sheet.Because existing bolt method is known, so its concept will be briefly described with reference to 10-2004-0026598 korean patent application case.
As illustrated in fig, in 10-2004-0026598 korean patent application case, longitudinal bolt preformed hole 13 and cross bolts preformed hole 12 are formed in section of jurisdiction.In this method, section of jurisdiction uses cross bolts preformed hole 12 connect in a lateral direction and engage, and longitudinal bolt preformed hole 13 is omitted, and longitudinal twisted wire of the present invention penetrates path and formed in a longitudinal direction.First, cross bolts preformed hole 12 is bolted fixing, and longitudinal twisted wire uses above method and prestretching and be anchored on longitudinal twisted wire and penetrate in path subsequently.
Figure 12 illustrates that cross bolts preformed hole 12 is tangent to each other and graphic by the fixing state of fixing bolt 7 and nut 8.
