As shown in fig. 1-12, a method for constructing an underground parking garage by a pipe-jacking tunnel comprises the following steps: the method comprises the following steps:
(1) The prefabricated C-shaped reinforced concrete member 11, embedded bars 111 are arranged on the inner side surface of the upper plate of the C-shaped reinforced concrete member 11 along three suspended sides, and two suspended corner embedded support pieces 112 are arranged. As shown in fig. 1, a C-type reinforced concrete member 11 is used at the edge of an underground parking garage.
(2) The reinforced concrete upper plate 12 and the reinforced concrete lower plate 21 are prefabricated, embedded bars 111 are arranged on the inner side surface of the reinforced concrete upper plate 12 along the periphery, and supporting pieces 112 are embedded at four corners. As shown in fig. 2, the reinforced concrete upper plate 12 is structured for constructing a tunnel in the middle portion of an underground parking garage.
(3) The suspending side of the prefabricated C-shaped reinforced concrete member 11 is sealed by a supporting sealing member 15 to form a frame-type jacking pipe I13. As shown in fig. 3, the frame-type jacking pipe i 13 comprises a C-type reinforced concrete member 11 and a supporting and closing member 15, wherein the supporting and closing member 15 is detachable, and a space corresponding to the positions of the C-type reinforced concrete member 11, the embedded support 112 of the reinforced concrete upper plate 12, and the embedded bars 111 is reserved. The C-type reinforced concrete member is actually shaped like a mouth, with one side being removed. The frame-shaped jacking pipe I13 manufactured in a closed mode is a rectangular frame.
(4) The two ends of the precast reinforced concrete upper plate 12 and the reinforced concrete lower plate 21 are sealed by the supporting sealing member 15 to form a frame-type jacking pipe II. Frame type pipe jacking II can be divided into two types: as shown in fig. 4, the first frame-shaped jacking pipe ii 141 is schematically adapted to a frame-shaped jacking pipe ii without the position of the designed column 18. As shown in fig. 5, a second frame-type jacking pipe ii 142 is schematically shown, and is adapted to the frame-type jacking pipe ii in which the position of the upright 18 is designed. The difference is that: the support enclosure 15 includes a central portion and left and right side members 151. The left and right side members 151 are detachable. The width of the left and right side members 151 of the second frame-type push bench ii 142 is equal to half the width of the column 18. So that the space left after the removal of the side members 151 of one side of the four frame-type push pipes ii 142 adjacent to each other can be used as the column 18.
(5) Setting a working well, namely setting a jacking well and a receiving well.
(6) Firstly, the frame-type jacking pipe I is jacked in and penetrated. As shown in fig. 6, a channel formed by a row of frame-type jacking pipes i is adapted to the side position of an underground parking garage, and is called a side channel 16.
(7) And then sequentially jacking the frame-type jacking pipes II according to the design to finish the frame-type jacking pipes II of the first column. Namely, the first column 18 is designed between the nth column and the n+1th column frame type jacking pipe II; the n+1st row of frame-type jacking pipes II is the frame-type jacking pipe II for completing the first row of upright posts. The second frame-shaped jacking pipe II 142 is pushed in at the position where the upright 18 is arranged, and the first frame-shaped jacking pipe II 141 is pushed in at the position where no upright 18 is arranged, and a middle channel is arranged between the side channels 16 formed by the two rows of frame-shaped jacking pipes I. As shown in fig. 7, a channel formed by a row of first frame-type jacking pipes ii 141 is called a column-free middle channel 171. As shown in fig. 8, a channel formed by inserting two adjacent second frame-shaped jacking pipes ii 142 between a plurality of first frame-shaped jacking pipes ii 141 according to the position rule of the upright posts 18 is an upright post-containing middle channel 172, and as shown in fig. 9, an upright post 18 is arranged between the two upright post-containing middle channels 172.
(8) The supporting and closing member 15 at the upright post is removed, upright post reinforcing steel bars are arranged, an upright post die cavity is arranged, and concrete is poured into the upright post. The upright posts 18 are embedded with reinforcing bars and can be connected with the reinforcing bars of the cross beam when the cross beam is poured. As shown in fig. 9, the support closing member 15 of the column part is removed, that is, one side edge part 151 of the support closing member 15 of the second frame-type push bench 142 of the column part is removed, and spaces left after the removal of the side edge members 151 of one side of four frame-type push bench 142 of the second adjacent one are used as the columns 18. If the columns 18 are designed at both ends of the column-containing intermediate channel 172, only the support closing members 15 of the corresponding column portions of the two adjacent frame-shaped push pipes ii of the column portions need to be removed, and the width of the removed support closing members 15 is equal to the width of the columns 18. As shown in fig. 10, the post 18 is cast.
(9) The upper member 152, which is the uppermost layer of the supporting and closing members 15 between the first column 18 and the C-type reinforced concrete member 11, is removed, and the upper plate is supported by the embedded support 112 after the first closing and closing member, that is, the upper member 152, is removed, because the height of the embedded support 112 of the upper plate of the C-type reinforced concrete member 11 and the upper plate 12 is the same as that of the upper member 152, which is the first layer supporting and closing member. Fig. 11 shows the structure after the upper member 152 is removed.
(10) And arranging transverse beam steel bars at joints 20 between the upper plates of the C-shaped reinforced concrete members 11 and the upper reinforced concrete plates 12, arranging transverse beam die cavities, and pouring concrete to manufacture transverse beams. The cross beam is connected to the upright 18. The beams are divided into a layer beam 191 and a column beam 192, and the column beam 192 is positioned below a gap 20 between one column of C-shaped reinforced concrete members 11 and the adjacent column of reinforced concrete upper plates 12 and below a gap 20 between the adjacent two columns of reinforced concrete upper plates 12; the row beams 191 are positioned below the adjacent row seams and span the length of the two-sided C-reinforced concrete members 11. The upper periphery of the upright 18 is connected with the cross beam by embedded bars, as shown in figures 11 and 12.
(11) And removing other supporting closing members to obtain the parking space of the first part. As shown in the structures of fig. 11 and 12.
(12) Repeating the steps according to the requirements until the rest construction is completed. All required frame-type jacking pipes II and frame-type jacking pipes I13 can be jacked in the step (7). And then, performing the work from the step (8) to the step (11), and finally finishing the ground.
