The specific embodiment
Embodiment mono-, as shown in figure 1 to figure 13, the disclosed this prefabricated pipe gallery of the utility model, by some prefabricated tube couplings 1, be assembled, each prefabricated tube coupling 1 is by top board 11, biside plate 12 and base plate 13 surround, wherein top board 11 and side plate 12 are prefabricated, base plate 13 is prefabricated or cast-in-place, between top board 11 and side plate 12, between side plate 12 and base plate 13, the concrete cast-in-situ band 15 by pre-buried separately reinforcing steel structural member 14 and corresponding reinforcing steel structural member place 14 forms rigid unitary respectively, between the top board 11 of contiguous prefabricated tube coupling 1, between side plate 12, be provided with drawing fastening assembly 2.The upstream face of contiguous prefabricated tube coupling 1 splicing seams is provided with water blocking tape 3, there is anticracking grout layer 4 inner side.
To drawing fastening assembly 2 for bolt or studs, screw mandrel and corresponding nut, packing ring, each part is galvanized part, be bolt and nut, packing ring accordingly shown in Fig. 8.
Top board 11 is rectangular flat, the dual-side of its length direction is embedded with the overhanging reinforcing steel structural member of horizontal symmetrical 14, and inner side, its width two ends is useful on the connecting hole 16 that bolt or studs, screw mandrel pass and the technology groove 17 of being convenient to assembling nut, packing ring.
There is recess 18 along its length the top margin inner side of side plate 12.14 reinforcing steel structural members protrude upward, from the base of side plate 12, stretch out downwards from the bottom surface of recess 18 respectively.Side plate 12 short transverse two ends inner sides are useful on the connecting hole 16 that bolt or studs, screw mandrel pass and the technology groove 17 of being convenient to assembling nut, packing ring.The reinforcing steel structural member 14 of top board 11 both sides stretches into respectively in the recess 18 of the side plate 12 corresponding sides in upper end, and top board 11 is consistent with quantity with reinforcing steel structural member 14 positions pre-buried on side plate 12.
Base plate 13 is elongated plates, and the bilateral symmetry of its upper surface length direction is provided with outstanding installation positioning strip 131, and the width center position that positioning strip 131 is installed has elongated lower narrow wide trapezoidal groove 132.The base of reinforcing steel structural member 14 from trapezoidal groove 132 protrudes upward, consistent with on side plate 12 of pre-buried reinforcing steel structural member 14 positions and quantity on base plate 13, reinforcing steel structural member 14 bottoms pre-buried on side plate 12 are positioned at base plate 13 tops, colligation overlap joint or welding between the corresponding reinforcing steel structural member on base plate 13 and side plate 12.
In the present embodiment, the pre-buried reinforcing steel structural member 14 in top board 11 and side plate 12 upper ends adopts anchor ring, and reinforcing steel structural member 14 pre-buried on side plate 12 lower ends and base plate 13 adopts double dowel.
Top board 11 and the side plate 12 of each prefabricated tube coupling 1 are prefabricated in the factory, base plate 13 can be prefabricated also can be cast-in-place, prefabricated component is transported to job site by the vehicles.For the ease of handling, when each plate is prefabricated, all arranges and hang nail or suspension ring on it.
The prefabricated tube coupling Assembling step prefabricated for base plate 13 is as follows: 1, ground is dug to respective design absolute altitude, after building one deck concrete cushion, handling base plate 13 is to precalculated position, by side plate 12 handlings to the corresponding position on base plate 13, and with bracing element fixed side 12, each dowel difference spot welding that base plate is pre-buried with side plate junction is connected, corresponding anchor ring place concreting is cast-in-place is again with 15 to make to form rigid unitary between base plate 13 and side plate 12, finally the both sides of trapezoidal groove is built.2, the upper end to biside plate 12 by top board 11 handlings, the anchor ring of top board 12 both sides is stretched in the recess 18 of side plate 12 inner sides, upper end, adjust the position of top board 11 until the anchor ring position correspondence on top board 11 and side plate 12 is good, length direction along prefabricated tube coupling 1 inserts perforated rebar or cable wire 6, between perforated rebar or cable wire 6 and anchor ring, concreting is cast-in-place again after fixing is with 15 in spot welding, makes top board 11 and side plate 12 form rigid unitary.So far, a rigidly connected integral prefabricated tube coupling construction is complete.
After adjacent prefabricated tube coupling 1 is good according to above-mentioned steps assembling construction, it is next the construction at contiguous prefabricated tube coupling 1 splicing seams place.First by fastening to drawing fastening assembly 2 respectively adjacent top board 11 to be connected with side plate 12, to drawing corresponding splicing seams place on the bolt of fastening assembly 2 or studs, screw mandrel to be connected with waterproof rubber gasket 5, then carry out the construction of water blocking tape 3.Water blocking tape 3 lays respectively at the upstream face of adjacent top board 11 and side plate 12, comprises successively asphalt rubber waterproofing unction layer 31, EPDM waterproof adhesive tape layer 32, Bituminous hemp fiber layer 33.Water blocking tape 3 carries out slip casing by pressure construction at each splicing seams place of piping lane inner side after having constructed, and forms anticracking grout layer 4 seal in the inner side of each splicing seams.
Piping lane carries out corresponding municipal engineering pipe installation installation work again after having assembled.
When base plate 13 is cast-in-place, before side plate 12 and base plate 11 assemblings, ground is dug to respective design absolute altitude, after building one deck concrete cushion, base plate 13 is built in case designing requirement thereon, until base plate 13 is standing while reaching requirement, starts to assemble successively by above-mentioned steps side plate 12 and the top board 11 of prefabricated tube coupling 1.
After the prefabricated tube coupling of some assembles, in the inside of piping lane, splicing seams place carries out slip casing by pressure operation, forms anticracking grout layer at each splicing seams place, so that carry out waterproof reparation while having water blocking tape to lose efficacy.
Embodiment bis-, and as shown in Figure 14 and Figure 15, the difference of the present embodiment and embodiment mono-is: base plate 13 is rectangular flat, and pre-buried double dowel protrudes upward from the bilateral symmetry of plate upper surface length direction; Colligation overlap joint between corresponding dowel on side plate and base plate.Other structure of the present embodiment is with embodiment mono-.
Embodiment tri-, as shown in figure 16, the difference of the present embodiment and embodiment mono-, embodiment bis-is: upper surface length direction one side of base plate 13 is provided with outstanding installation positioning strip 131, the width center position that positioning strip 131 is installed has elongated lower narrow wide trapezoidal groove 132, the base of reinforcing steel structural member 14 from trapezoidal groove 132 protrudes upward, and the reinforcing steel structural member 14 of opposite side directly stretches out from the upper surface of base plate 13.When side plate 12 and base plate 13 are assembled certainly, carry out according to the corresponding operating of above-mentioned two embodiment respectively both sides.Other structure of the present embodiment is with embodiment mono-.
Reinforcing steel structural member pre-buried on each plate of prefabricated tube coupling also can adopt anchor ring.If pipeline is more, be convenient to the layer-built cables installation of pipeline, can be when side plate be prefabricated, sidewall arranges bracket within it, prefabricated middle plate is set on bracket and piping lane is divided into two-layer up and down.For the very high piping lane of waterproof requirement, the water blocking tape between side plate meet water layer can add one deck waterproof roll.
