Abstract
The utility model discloses an underground pipe network inspection well concrete assembly comprising a well lid, a concrete upper neck cylinder member, a concrete middle section member and a concrete pedestal assembly. A cylinder port of the concrete upper neck cylinder member is matched with the concrete well lid; and the concrete middle section member is arranged between the concrete upper neck cylinder member and the concrete pedestal assembly and inserted with thereabove to form an inspection well via a sealing member and a wedge. Inspection assembly members can be prefabricated on a manufacturing site and on-site concrete casting or well bricklaying are avoided, so on-site construction time can be greatly shortened; the inspection well is formed in an assembling caisson construction way; the well is sunk as soil is dug; soil is dug in the well, so disruption to a foundation is reduced; enclosure of a steel sheet pile or a wood pile is unnecessary, thereby providing the underground pipe network inspection well concrete assembly with fast construction speed, high work efficiency and low cost; and an antiseptic lining of the assembly enhances leakage and corrosion resisting performance of the inspection well.

The specific embodiment
As shown in Figure 1, be the utility model network of underground manhole concrete segment schematic diagram.Network of underground manhole is formed by each concrete segment assembling open caisson.The assembly that open caisson is installed is from bottom to top: base assembly, stage casing part 6, upper hind neck barrier part 7, until upper hind neck barrier part 7 is installed, well lid 9 is covered on neck nozzle, and form a manhole.Each specification shape prefabricated component that stage casing part 6, upper hind neck barrier part 7 form the anticorrosion internal mold of fabricating yard made, external mold, reinforcing bar dragon.Internal mold is the liner 8 of manhole, and liner adopts etch-proof glass fiber reinforced plastic or plastic material, and this example adopts glass-reinforced plastic material.Concreting on prefabricated component subsequently, liner 8 is connected into one with concrete, until maintenance reaches intensity, makes manhole concrete segment through vibrating.Base assembly comprises concrete bed part 2, base liner 17, and both are prefabricated respectively, after concrete bed part 2 and base liner 17 are installed, is connected.On each assembly, be shaped with and carve mouth, for connection mutual between each assembly.Carving of each assembly is all shaped with seal groove on mouth.The utility model, making place precast concrete open caisson assembly, can shorten on-site construction time greatly, reduces construction plant.
The shape of concrete stage casing part 6 is cast, is shaped with to carve on mouth 11, lower end collar to be shaped with down and to carve mouth 10 on its upper end collar, and upper and lower carving on mouth 11,10 is shaped with seal groove.
The shape of concrete upper hind neck barrier part 7 is bottle-neck type, the inside and outside collar size in its lower end is corresponding with concrete stage casing part 6 upper end collar sizes, on the collar of lower end, be shaped with on the part of concrete stage casing, carve mouthfuls 11 match under carve mouthfuls 10, under carve on mouthfuls 10 and be shaped with seal groove, corresponding with the seal groove of carving mouthfuls 11 on the part of stage casing.
The shape of concrete bottom holder assembly is cartridge type, comprise concrete bed part 2, base liner 17, the shape of concrete bed part 2 is cast, the inside and outside collar size in its upper end is corresponding with concrete stage casing part 6 lower end collar sizes, on the collar of upper end, be shaped with under concrete stage casing part 6, carve mouthfuls 10 match on carve mouthfuls 11, on carve on mouthfuls 11 and be shaped with seal groove, corresponding with the seal groove of carving mouthfuls 10 under the part of stage casing.The bottom of base element 2 is shaped with pipeline through hole 13, lower end is shaped with sword pin 15, and sword pin 15 is convenient to base element 2 and is sunk.The shape of base liner 17 is cartridge type, and base plate and the cylindrical shell of its bottom are integral, and top is shaped with the pipeline through hole 13 corresponding with concrete bed part 2.
The mouth of carving of each fills sealing ring 12 on seal groove while plugging together, and for the sealing of assembly, that respectively carves mouthful is shaped as spigot-and-socket or F type.After concrete bed part 2 sinks to putting in place, stage casing part 6, upper hind neck barrier part 7 all install, the shaft bottom of macadam 16, plain concrete layer 14, concrete floor 1 is built, tubulature road 4 stretches in the through hole 13 of base element 2, refill base liner 17 on concrete floor 1, base liner 17 is connected with concrete bed part 2.On through hole 13, be equipped with sealing mat 3, gland 5, for sealing, Leakage prevention.
As shown in Figure 2, be that base element is in place to excavating ground schematic diagram.Below by figure, assembly sinking process is further described respectively again: measure the position of manhole setting with transit, then by the position to the arranging in place base element of manhole 2, so that excavation ground.There is the sinking of sword pin 15 for base element 2 lower end of base element 2.
As shown in Figure 3, be that open caisson puts in place and is placed in schematic diagram on concrete floor.Build manhole with sinking assembly, base element 2 is placed in behind excavation ground, starts excavation and fetches earth, fetch earth available grapple or manually fetch earth of excavation.The sword pin 15 of base element is with base element 2 isostatic settlings, if unbalanced sinking will be rectified a deviation, can or fetch earth in lower end at a high side upper end ballast of base element 2 more.The open caisson while fetching earth like this, beyond open caisson, does not excavate on ground, fetches earth and fetch earth in well, reduces ground disturbance, reduces the impact on periphery roadbed and building.Without going along with sb. to guard him of steel sheet pile or timber, speed of application is fast, and operating efficiency is high.In the time that the upper end of base element 2 sinks down into ground line position, stage casing part 6 is placed on to the upper end of base element 2, on base element 2, carve mouthfuls 11 with stage casing part 6 under carve mouthfuls 10 and insert mutually, connect between the seal groove of carving mouth sealing ring 12 be housed, for the sealing of open caisson, with Leakage prevention.Then continue to excavate the sinking assembly that fetches earth.
In the open caisson process of assembly, to constantly measure the absolute altitude of open caisson, when the bottom surface of base element 2 is when setting absolute altitude position, should stop excavation and fetch earth.
Shaft bottom absolute altitude is adjusted to setting absolute altitude, lays subsequently macadam 16 compacting, on macadam 16, build plain concrete layer 14.Treat that plain concrete 14 reaches intensity, assembling reinforcement concreting base plate 1 (seeing Fig. 3) on plain concrete 14.
Concrete floor 1 reaches after intensity, and pipe laying 4 between two manholes (push pipe or pipe laying), stretches in the end of pipeline 4 in the through hole 13 of base element 2.Refill base liner 17 on concrete floor 1, the through hole 13 of base liner 17 is corresponding with the through hole 13 of base element 2.Then fill by cement paste solid integral to base liner 17 and concrete bed part 2, the shape of the concrete bottom holder assembly after connection is solid is cartridge type.Base liner 17 adopts etch-proof glass fiber reinforced plastic or plastic material, and this example adopts glass fiber reinforced plastic.Leak-proof sealing pad 3 is installed on through hole 13, gland 5 is installed on sealing mat 3, gland 5 is connected by bolt and base element 2.Guarantee that through hole 13 and pipeline 4 seal (seeing Fig. 3).
As shown in Figure 1, the lower end of upper hind neck barrier part 7 is carved to mouthfuls 10 and carve mouthfuls 11 with the upper end of stage casing part 6 and insert mutually, two-phase is inserted on the seal groove of carving mouth sealing ring 12 is installed, and then well lid 9 is placed in to neck nozzle, forms a leakproof corrosion-resistant manhole.
