Detailed Description
The first embodiment is as follows: a construction method of a comprehensive pipe gallery.
The invention provides a construction method of a cast-in-place large-scale comprehensive pipe gallery, which is suitable for the construction condition that an outer side template of a side wall of the comprehensive pipe gallery cannot be erected due to space limitation.
As shown in fig. 1, the present invention comprises the steps of:
a. according to the construction drawing, at first dig at the subaerial pit of establishing of planning to lay utility tunnel to lay the utility tunnel, dig the pit width of establishing and be equal to the width of the utility tunnel of treating to lay. When the underground comprehensive pipe gallery to be paved is long, a sectional construction mode is adopted.
b. The bottom of the well-excavated pit slot is dug flatly, a concrete cushion layer is poured on the bottom of the slot, a reinforcing mesh in the bottom plate 4 of the utility tunnel is bound on the concrete cushion layer at the bottom of the slot, then a bottom plate side die and an splayed die are erected, concrete is poured on the bottom of the slot to form the bottom plate 4 of the utility tunnel, and reinforcing heads connected with the reinforcing mesh in the side wall 9 and the intermediate wall 5 are reserved on the reinforcing mesh in the bottom plate 4. After the bottom plate 4 is poured, the rebar heads are exposed to the outside to connect with the rebar grid in the side walls 9 and the intermediate wall 5.
c. Install the reinforcing bar net in the pipe gallery intermediate wall 5 on utility tunnel's bottom plate 4, the vertical bar of the reinforcing bar net in the intermediate wall 5 once to the top does not do the overlap joint, and the horizontal muscle ligature is in the vertical bar outside.
d. Then, a partition wall formwork 6 and a partition wall formwork support are erected on two sides of the steel mesh in the partition wall 5 in the comprehensive pipe gallery, and the partition wall formwork support used in the invention is a partition wall support rod 7 connected to the outer plate surface of the partition wall formwork 6 and the bottom plate 4. After the partition wall formworks 6 are erected, concrete is poured between the two partition wall formworks 6 to form the intermediate partition wall 5.
e. Then use ultrasonic wave lateral wall appearance to detect the straightness that hangs down of utility tunnel pot side wall 1, level and smooth utility tunnel's pot side wall 1, ensure that utility tunnel's pot side wall 1 is perpendicular to use as the outside template of waiting to pour pipe rack side wall 9 with level and smooth utility tunnel's pot side wall 1.
f. Then the reinforcing mesh in the utility tunnel side wall 9 and the reinforcing mesh in the top plate 2 are installed, the vertical reinforcing bars of the reinforcing mesh in the utility tunnel side wall 9 are not lapped on one single top, the lower end is anchored in the bottom plate 4, and the upper end is anchored in the concrete of the top plate 2.
g. After the reinforcing mesh in the utility tunnel side wall 9 is bound, the inside formwork and the inside formwork support of the utility tunnel side wall 9 are installed, and the utility tunnel top plate 2 and the top plate formwork support are installed.
The inboard formwork support of boundary wall 9 is provided with a plurality of groups in this embodiment, and the length direction interval that the inboard formwork support of a plurality of groups was followed the piping lane sets up, and every inboard formwork support of group includes six vaulting poles, and six vaulting poles setting is in same and inboard template looks vertically plane, and the one end of six vaulting poles is all fixed on the outer face of interior side form to evenly arrange on the outer face of interior side form of stiff end of six vaulting poles. Among the six bracing pieces, the other ends of the three bracing pieces incline downwards to form inclined bracing pieces 8, and the end parts of the inclined ends of the three inclined bracing pieces 8 are fixed at the same position on the comprehensive pipe gallery bottom plate 4 through screws. The other three support rods are horizontally arranged and are transverse support rods 3, the other ends of the three support rods 3 are fixed on the outer plate surface of the partition wall formwork 6 of the middle partition wall 5, so that a good supporting effect can be achieved on the upper end of the inner side formwork of the side wall 9, and the upper end of the inner side formwork is easily deformed due to uneven stress when the inner side formwork is supported by the inclined support rods, so that the poured side wall 9 cannot meet the quality requirement.
h. Then pour the concrete between the pit side wall 1 of utility tunnel and the inboard template of side wall 9, pour the concrete again to the roof template of utility tunnel, when pouring the concrete of side wall 9, the mode that the sectional type was pour is adopted in the upper and lower direction to side wall 9 to pour in turn between the section of utility tunnel left and right sides side wall 9 and the section.
i. After the concrete of the top plate 2 of the comprehensive pipe gallery, the concrete of the side wall 9 and the concrete of the intermediate wall 5 reach the form removal strength, the inner side formwork and the inner side formwork support of the side wall are removed, the top plate formwork and the top plate formwork support are removed, the partition wall formwork 6 and the partition wall formwork support 7 of the intermediate wall are removed, and then the pouring construction work of the rear comprehensive pipe gallery is completed.
Example two: a unilateral formwork structure of utility tunnel side wall.
As shown in fig. 1, the present invention includes a reinforcing mesh in the side wall 9, an inside formwork of the side wall, and an inside formwork support supporting the inside formwork, and uses the pit side wall 1 of the vertical utility tunnel of the utility tunnel as an outside formwork of the side wall 9. The inside template of side wall 9 sets up immediately on the bottom plate 4 of the utility tunnel of pouring, and the reinforcing bar net of side wall 9 sets up between the pit slot lateral wall 1 of utility tunnel and the inside template of side wall 9, and its lower extreme anchors in the concrete bottom plate, and the upper end anchors 2 reinforcing bar nets in the roof concrete and meets. The inner side template supports are provided with a plurality of groups, and the inner side templates of the groups are arranged at intervals in the length direction of the comprehensive pipe gallery. In this embodiment, every inboard template of group supports including six vaulting poles, and six vaulting poles set up in the same vertical plane with inboard template looks vertically, and the one end of six vaulting poles is all fixed on the outer face of inside template to evenly arrange on the fixed position vertical line in the inboard template, the vertical line in this implementation is the intersection line of six vaulting pole place vertical plane and inboard template. In six inboard formwork support, three of them vaulting poles are diagonal brace 8, and the other end downward sloping of diagonal brace 8 to fix same position department on utility tunnel bottom plate 4 through the screw, three other vaulting poles level sets up for horizontal brace 3, and the other end of three horizontal brace 3 is fixed on the partition wall template 6 of the mid-board 5 that props up in advance.
