Abstract
The invention relates to a large-sized glass fiber-reinforced plastic inspection shaft with a ladder stand. The large-sized glass fiber-reinforced plastic inspection shaft with the ladder stand comprises a shaft, an underground cover and an aboveground cover, wherein a branch tube is inserted into the lower end of the shaft, and a hot melt adhesive and a manually-pasted sticking substance are injected into the joint, so that the branch tube and the shaft are fixed together. The large-sized glass fiber-reinforced plastic inspection shaft has the advantages of high ring stiffness, convenience in construction, leakage resistance, high corrosion resistance, long service life, low maintenance cost, low comprehensive manufacturing cost, and contribution to increasing the construction efficiency and lowering the production cost.
Description
Technical field
The invention belongs to the technical field of pipe drainage ancillary structure, particularly relate to a kind of fiber glass reinforced plastics inspection well product.
Background technology
At present, the pipe duct manhole product used of sewage effluent, waste water and rainwater mainly contains three kinds both at home and abroad: the manhole of laying bricks, concrete inspection well, plastic inspection well.Wherein these three kinds of manhole structures also come with some shortcomings in practical application and manufacturing process: traditional build by laying bricks or stones manhole, steel concrete manhole because of speed of application slow, impact on environment and urban traffic is large, do not meet the requirement of civilized construction, rapid construction, quality stability is poor, especially the intensity of manhole of laying bricks is low, at the joint of plastic pipe and manhole, easily occur that the problems such as effluent seepage cause severe contamination to soil environment especially.Though and plastic inspection well can prevent seepage, because ring stiffness is lower, the stress of resistance to ring poor corrosion resistance, can only meet some areas requirement, can not use for a long time, maintenance times is many.And the well seat of manhole key part need to adopt once injection moulding, equipment investment, processing cost are higher.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide that a kind of ring stiffness is high, easy construction, antiseep, and strong corrosion resistant, long service life, maintenance cost is low and comprehensive cost is low, is conducive to the large-scale manhole that improves efficiency of construction, reduces production costs.
To achieve these goals, the technical solution used in the present invention is: a kind of large glass steel manhole with cat ladder, comprise pit shaft, down-hole lid and aboveground lid, the described pit shaft lower end arm of having pegged graft, and in junction, inject PUR and hand and stick with paste adhesive and realize the fixing of arm and pit shaft.
Described pit shaft and down-hole lid splicing, described splicing construction covers and pit shaft socket for being provided with the down-hole of steel mesh reinforcement, and fixes by concrete.
Described pit shaft and the splicing of aboveground lid, described splicing construction is for being directly enclosed within the aboveground lid that is provided with steel mesh reinforcement the pit shaft top that sealing ring is installed.
Described shaft in wall is provided with cat ladder.
Described cat ladder adopts the hand mode of sticking with paste to be fixed on shaft in wall by adhesive.
Described mineshaft diameter is 600mm to 4000mm.
Compared with prior art, the invention has the beneficial effects as follows: ring stiffness is high, save cost, improved production efficiency and reduced production difficulty, only need carry out simple training to producers and can participate in producing.

Specific embodiments
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, a kind of large glass steel manhole with cat ladder, comprise pit shaft 1, arm 2, down-hole lid 3, aboveground lid 4, cat ladder 5, sealing ring 6 and steel mesh reinforcement 7, described pit shaft 1 inwall is provided with cat ladder 5, the described pit shaft 1 lower end arm 2 of having pegged graft, and in junction, inject PUR and hand and stick with paste adhesive and realize the fixing of arm 2 and pit shaft 1.
Described pit shaft 1 and 3 splicings of down-hole lid, described splicing construction is the down-hole lid 3 and pit shaft 1 socket that will be provided with steel mesh reinforcement 7, and fixes by concrete.
Described pit shaft 1 and 4 splicings of aboveground lid, described splicing construction is for to be directly enclosed within by the aboveground lid 4 that is provided with steel mesh reinforcement 7 pit shaft 1 top that sealing ring 6 is installed.
As shown in Figures 2 and 3, first open two installing holes on pit shaft 1, the surfaces externally and internally peripheral extent with sander polishing wellbore hole and arm, is inserted in pit shaft 1 hole by arm 2, on 4 points that connect gap position, injects PUR, and fixedly arm 2.The mode of sticking with paste by hand invests adhesive 8 materials such as grade the link position of pit shaft 1 and arm 2 by a certain percentage, then the mode that the cat ladder of having made 5 is stuck with paste to technique by hand is fixed on pit shaft 1 wall, treats that it solidifies.
As shown in Figure 4 and Figure 5, at pit shaft 1, near one side of perforate, bore 4 apertures, the reinforcing bar of 2 intersections is installed, in mould, place the steel mesh reinforcement 7 of having tied up, then pit shaft 1 is positioned over to 8 li of down-hole box cover dies, in putting, again guiding gutter mould is positioned on arm 2, is poured into concrete, treat that it solidifies.
As shown in Figure 6 and Figure 7, sealing ring 6 is installed and pit shaft 1 tops, the more aboveground lid 4 of having poured into a mould is placed on sealing ring, utilize the weight press seal circle of aboveground lid 4 self to reach the effect of sealing.
