Specific embodiment
A kind of replacement method of municipal administration well lid installing frame, includes the following steps,
As shown in Figure 1, step 1: a round mark concentric with the old installing frame 11 of well lid is drawn out on road surface 1 using compasses 2
Remember line；
As shown in Figures 2 and 3, step 2: after fork truck 5 transports cutter device 4 above mark line, using in cutter device 4
Drilling pipe 45 is cut into an annular grooving along mark line on road surface 1；
As shown in Figures 4 and 5, step 3: fork truck 5 using boom hoisting 6 by grooving go out 1 surface layer of road surface hang out after, on road surface 1
Form a mounting groove；
It as shown in Figures 6 and 7, will using more leveling bars 7 step 4: new washer and prefabricated installing frame 8 are transported in mounting groove
Prefabricated 8 surface of installing frame is adjusted to concordant with road surface 1, can if 8 bottom surface of prefabricated installing frame and installation groove bottom gap are larger
To pour into some sandstones into gap；
As shown in figure 8, step 5: being sealed using air bag 9 to the gap between prefabricated installing frame 8 and vertical shaft 10；
Step 6: plain-water slurry is circulated into the gap between prefabricated installing frame 8 and mounting groove, cement slurry can not diffuse out seam
Gap, it is desirable that cement grout identity distance has 15CM or so distance from the ground, wherein used cement can be quick hardening cement, to cement
After solidification, air bag 9 is taken out from vertical shaft 10；
As shown in figure 9, step 7: to the gap of the underfill cement slurry between prefabricated 8 side of installing frame and mounting groove as change
Shape seam, then blocks deformation joint using pitch, removes each leveling bar 7, completes the replacement to municipal well lid installing frame.
After drilling pipe 45 in cutter device 4 is cut into an annular grooving on road surface 1, fork truck 5 will using boom hoisting 6
1 surface layer of road surface, waste and old installing frame 11 and old washer are hung out together, and new washer and prefabricated installing frame 8 are placed into mounting groove later
It is interior, finally the gap between prefabricated installing frame 8 and road surface 1 is blocked using cement or pitch, it is broken to eliminate pneumatic pick
The process on road surface 1 reduces dust and disintegrating slag.
As shown in Fig. 5 to 7, need to be equipped with dreg-containing disk 3, institute in vertical shaft 10 below well lid before carrying out above-mentioned second step
Stating dreg-containing disk 3 includes plectane 31, is fixedly connected with a circle rubber slab 32 at 31 edge of plectane, more spiral shells are welded on plectane 31
Mother 33, is mounted on the first jackscrew 34, each 34 one end of the first jackscrew is resisted against on 10 inner wall of vertical shaft in each nut 33.
After the road surface 1 and waste and old installing frame 11 that will be come out by ring cutting are taken out, some sandstones or brick are had on roadbed
Equal sundries need to make in order to avoid these sundries are fallen in vertical shaft 10, therefore before hanging out road surface 1 and waste and old installing frame 11
Dreg-containing disk 3 is used, to catch the sundries fallen in work progress；On the other hand, it is sometimes desirable to which the well lid of replacement is applied in dirt
On well, if do not blocked to 10 well head of vertical shaft, the foul smell in well can be gushed out upwards, and when constructing, worker must face again
Well head, these foul smell gushed out can to worker construct bring discomfort, so to vertical shaft 10 blocked just very it is necessary to.Make
Plectane 31 can be fixed in vertical shaft 10 by multiple jackscrews, allow rubber slab 32 to be adjacent to 10 inner wall of vertical shaft, allow rubber by the used time
Plate 32 is close to 10 inner wall of vertical shaft, to prevent foul smell in well from gushing out and preventing sundries or tool from falling in well.
As shown in Figure 1, the compasses 2 include 2 ontology of compasses, idler wheel 21 is installed in 2 ontology of compasses, one supporting leg lower end,
Another supporting leg lower end is equipped with the sleeve 22 for being inserted into chalk.In use, compasses 2 are adjusted to after an angle admittedly
It is fixed, then by idler wheel 21 after waste and old 11 inner wall of installing frame, mark line, 4 edge of cutter device are drawn on road surface 1 using chalk
Label wire cutting, can thus allow the grooving being cut into and waste and old installing frame 11 coaxial, due to waste and old installing frame 11 with it is perpendicular
Well 10 is coaxial, therefore after being coaxially put into prefabricated installing frame 8 in mounting groove with vertical shaft 10, can guarantee prefabricated installing frame 8
Gap between periphery and mounting groove inner wall is uniform, enable to be cast in gap concrete or pitch to installing frame into
Row is uniformly bonded.
As shown in Figures 2 and 3, the cutter device 4 includes bracket, drilling pipe 45 and support plate, is equipped with multiple lead on bracket
Set and multiple oil cylinders 42, are equipped with guide rod 43, each 43 lower end of guide rod and 42 piston-rod lower end of each oil cylinder are uniform in each guide sleeve
Support plate connection, is equipped with hydraulic motor 44,44 output shaft of hydraulic motor connect with drilling pipe 45, sets on bracket on the supporting plate
There are two intubations 41 corresponding with 5 pallet fork of fork truck.Hydraulic motor 44 and each oil cylinder 42 can connect with the hydraulic system of fork truck 5
It is logical, in use, controlling each 42 synchronization lifting of oil cylinder by manual three-position four-way valve, hydraulic horse is controlled by manual two position two-way valve
Up to 44 rotations, fork truck 5 can star fluid-power motor after by 45 alignment mark line of drilling pipe, then be bored by the control of each oil cylinder 42
Pipe 45 is slowly fed, while to watering at drilling pipe 45, can be by drilling pipe 45 from road surface 1 after drilling pipe 45 cuts to base course
Extraction, completes cutting, and cutter device 4 is transported to other places by fork truck 5.
As shown in Figures 4 and 5, the curved bar 61 that 6 two one end of boom hoisting are hinged on is fixed respectively two 61 one end of curved bar
It is connected with one piece of curved splint 62, wherein a curved bar 61 is connect by wirerope with 5 pallet fork of fork truck far from intermediate plate one end.It uses
When, the waste and old installing frame 11 being cut into and road surface 1 can be taken out by fork truck 5, be used simple and convenient.
As shown in FIGS. 6 to 8, the leveling bar 7 includes the body of rod 71, and 71 one end of the body of rod is connected by screw and prefabricated installing frame 8
It connects, other end is equipped with the second jackscrew 72, and the second jackscrew 72 is resisted against on road surface 1.
The air bag 9 includes support tube 91, emulsion tube 92 is cased with outside support tube 91,92 upper and lower ends of emulsion tube are propped up respectively
The connection of 91 upper and lower ends of stay tube, the gap between emulsion tube 92 and support tube 91 are connected by hose 94 and inflator 93.
First pass through rotation leveling bar 7 on jackscrew, by prefabricated installing frame 8 adjust to it is concordant with road surface 1 and with vertical shaft 10 together
Axis is being inflated using inflator 93 into the gap between emulsion tube 92 and support tube 91, to prefabricated installing frame 8 and vertical shaft 10
Between gap be sealed, then use in the gap that plain-water slurry is poured between prefabricated installing frame 8 and mounting groove, by
In closure of the emulsion tube 92 to the gap between prefabricated installing frame 8 and vertical shaft 10, therefore plain cement will be unable to be flowed into vertical shaft 10
In, after plain cement will solidify, so that it may air bag 9 is taken out, it, can be full of seam since plain-water slurry is fluid liquid
Gap avoids generating hole in set cement.
Prefabricated installing frame 8 includes precast concrete annular element, and installing frame is arranged in concrete annular element.Prefabricated installing frame
8 can be pre-formed using mold in the factory, reduces the usage amount of live cement or pitch, so that theing cement solidifies the time
Shorten, improves construction efficiency.
