Fig. 3 is a schematic view of a gate segment section of an original roadway in the gate segment roadway construction method of the present invention.
Detailed Description
As shown in fig. 1, the section AB from point a to point B of the roadway is a gate segment roadway, and the length of the gate segment roadway is 11 m.
As shown in fig. 2, in the construction method of the existing gate-segment roadway, the gate-segment roadway is a straight-wall semicircular arch roadway, and all supports are supported above an arch base line. When the door is pulled, 5 anchor rods in each row on the door pulling side of the original roadway are out of order after the door pulling section of the original roadway is expanded and brushed, 1 anchor cable is out of order, 2 meshes are out of order, 2 anchor rods, 1 anchor cable and 1 mesh need to be installed at the top again, 91 sets of anchor rods, 26 anchor cables, 39 meshes, 26 locksets and 260 anchors are consumed in 13 rows in total, and grout needs to be sprayed at the top again.
As shown in fig. 3, the construction method of the gate-segment roadway of the invention comprises the following steps:
constructing the top of the shifting side of the shifting section of the original roadway to a designed height when constructing the original roadway, so that the section shape of the shifting section of the original roadway is rectangular at the part close to the shifting side; the part close to the other side is a half of the section shape of other sections of the original roadway, namely the lower part is rectangular, and the upper part is an arched half; then, carrying out permanent support on the gate-shifting section of the original roadway; and then another roadway is constructed by shifting the door.
The method for permanently supporting the gate-poking section of the original roadway comprises the following steps: installing 13 rows of anchor cables on the gate pulling side of the gate pulling section along the tunneling direction of the roadway, and installing 1 anchor cable with the diameter of 22 mm and the length of L6200 on the top surface of the gate pulling side in each row; 13 rows of anchor rods are arranged on the door-shifting side of the door-shifting section along the tunneling direction of the roadway, 2 anchor rods phi 22 and L2500 anchor rods are arranged on the top surface of the door-shifting side of each row, and 3 anchor rods phi 22 and L2500 anchor rods are arranged on the side surface of the door-shifting side; 13 rows of net sheets are arranged on the gate-shifting side of the gate-shifting section along the tunneling direction of the roadway, 1 net sheet is arranged on the top surface of the gate-shifting side in each row, and 1 net sheet is arranged on the side surface of the gate-shifting side; and carrying out guniting support on the top and the side of the door-pulling section, wherein the guniting support is made of cement or concrete.
According to the construction method of the gate-poking section roadway, the cross section of the gate-poking section of the original roadway is directly constructed to the cross section of the gate-poking section roadway after the gate-poking section of the original roadway is expanded and brushed in the existing construction method of the gate-poking section roadway, 3 anchor rods on each row of side face are invalid after gate-poking construction, 1 mesh piece is invalid, 65 sets of anchor rods, 13 anchor cables, 26 mesh pieces, 13 locksets and 169 anchor agents are consumed in 13 rows in total, and re-spraying is not needed.
