The specific embodiment
The method of building shield tunnel with the tunnel segment structure with longitudinal twisted wire and transverse shearing force key of the present invention with reference to graphic detailed description.
First, of the present invention twisted wire is inserted and is anchored on the basic conception in the section of jurisdiction of the form assembling of z shape as follows.
The length of twisted wire is almost identical with the length of arranging four longitudinal sections of jurisdiction.This is because twisted wire connects and grappling take four longitudinal sections of jurisdiction as unit.The twisted wire of one unit is four section of jurisdiction row, as illustrated in Figure 10.Figure 10 schematically illustrates the graphic of four twisted wires about the row of the 4th in the section of jurisdiction assembly of Fig. 9 A1.
For instance, the twisted wire starting from the first row E2 of Figure 10 by prestretching and be anchored on the 4th row G1.All four twisted wires are through the A1 in the 4th row.Now, be different through starting point and the anchor point of four twisted wires of the A1 in the 4th row.The single twisted wire starting from first row is anchored in the A1 the 4th row.First this twisted wire fixes the A1 in the 4th row.In the time of the A1 fixing in this way in the 4th row, twisted wire is from secondary series, the 3rd row and the 4th leu order.In the time of the A1 not fixing in the 4th row, the twisted wire of secondary series, the 3rd row and the 4th row may be through the A1 in the 4th row.This is because the twisted wire in secondary series in fact can not be through the loose A2 in the 5th row.
The twisted wire starting from secondary series is through the A1 the 4th row, and can be anchored at the 5th row when only the twisted wire that started from first row E2 of A1 in the 4th row is fixing subsequently.This be because only the 4th row be fixed Shi Caike be anchored on the 5th row in.In addition, in order to be anchored in the 6th row since the twisted wire of the 3rd row, need to fix the 5th row and the 4th row simultaneously.
All four twisted wires are through all sections of jurisdiction, but only single section of jurisdiction is anchored in section of jurisdiction.A1 during three residue twisted wires are listed as through the 4th, and be sequentially anchored in next column subsequently.In other words, make basis, section of jurisdiction in abutting connection with test wall by the grappling of twisted wire, described basis reinforces through three twisted wires in abutting connection with test wall, and other bases are repeatedly formed on boring direction in abutting connection with test wall.
As illustrated in Figure 10, four twisted wires in the 4th row are the twisted wires that start from first row, secondary series, the 3rd row and the 4th row.That is to say, the twisted wire starting from first row E2 by prestretching and be anchored on the 4th row G1, and the twisted wire starting from secondary series E2 by prestretching and be anchored on the 5th row G1.Similarly, since the 3rd row E1 twisted wire by prestretching and be anchored on the 6th row G2 in, and since the 4th row E1 twisted wire by prestretching and be anchored on the 7th row G2 in.
In this way, four twisted wires that penetrate in path that are inserted in the 4th row are the twisted wires that start from first row, secondary series, the 3rd row and the 4th row, and are the supporting members that depends on the 4th leu order grappling and fix the 5th row, the 6th row and the 7th row simultaneously.This be the 4th row in A1 why be called as basis in abutting connection with test wall reason.
In addition, the section of jurisdiction in each row is with the arranged in form of z shape, and and then can increase because of the shear stress due to shear connector.In addition, because the only twisted wire in four twisted wires is anchored and is fixed in each row, so the overlapping rigidity of twisted wire can increase, and through assembling structure be firm for the differential pressure due to soil pressure and earthquake, and serve as for by the basis of the section of jurisdiction building continuously in abutting connection with test wall.Therefore, build and be easier to.In addition, the length of twisted wire is the length that makes loss minimum and make tensile force maximum.
Although described for convenience of description seven sections of jurisdiction, as long as the number of section of jurisdiction is odd number, identical concept is applicable to five or seven sections of jurisdiction.
But, in first row, secondary series and the 3rd row of Figure 10, basis is not set in abutting connection with test wall.This is inevitable phenomenon, because section of jurisdiction and twisted wire are to assemble with the form of z shape.
Existing bolt method and assemble method of the present invention are carried out in first row, secondary series and the 3rd row.Because existing bolt method is known, with reference to 10-2004-0026598 korean patent application case, its concept is described briefly.
As illustrated in Figure 11, 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 the method, section of jurisdiction is used 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 forms in a longitudinal direction.First, cross bolts preformed hole 12 is fixed by bolt, and twisted wire uses above method and prestretching and be anchored on longitudinal twisted wire and penetrate in path subsequently.
Figure 12 is tangent to each other and the graphic of bolt 7 and the fixing state of nut 8 that be fixed of explanation cross bolts preformed hole 12.
