Description

A kind of large glass steel inspection shaft with cat ladder

Technical field

The invention belongs to the technical field of pipe drainage auxiliary construction, particularly relate to a kind of fiber glass reinforced plastics inspection well product.

Background technology

At present, the pipe duct inspection shaft product used of sewage effluent, waste water and rainwater mainly contains three kinds both at home and abroad: the inspection shaft of laying bricks, concrete inspection well, plastic inspection well. Wherein these three kinds of inspection shaft structures also come with some shortcomings in practical application and manufacturing process: traditional build by laying bricks or stones inspection shaft, armored concrete inspection shaft because of speed of application slow, impact on environment and urban transportation is large, do not meet the requirement of civilized construction, rapid construction, quality stability is poor, especially the intensity of inspection shaft of laying bricks is low, at the joint of plastic tube and inspection shaft, 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 part of inspection shaft key 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 inspection shaft 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 inspection shaft with cat ladder, comprise pit shaft, down-hole lid and aboveground lid, the described pit shaft lower end arm of having pegged graft, and inject PUR and hand in junction 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 is to be provided with the down-hole lid and pit shaft socket of bar-mat reinforcement, and fixes by concrete.

Described pit shaft and the splicing of aboveground lid, described splicing construction is that the aboveground lid that is provided with bar-mat reinforcement is directly enclosed within to 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 inspection shaft with cat ladder, comprise pit shaft 1, arm 2, down-hole lid 3, aboveground lid 4, cat ladder 5, sealing ring 6 and bar-mat 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 inject PUR and hand in junction 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 that the down-hole lid 3 that is provided with bar-mat reinforcement 7 is socketed with pit shaft 1, and fixes by concrete.

Described pit shaft 1 and aboveground lid 4 splice, and described splicing construction is that the aboveground lid 4 that is provided with bar-mat reinforcement 7 is directly enclosed within to pit shaft 1 top that sealing ring 6 is installed.

As shown in Figures 2 and 3, on pit shaft 1, first open two installing holes, by the surfaces externally and internally peripheral extent of sander polishing wellbore hole and arm, arm 2 is inserted in to pit shaft 1 hole, on 4 points that connect gap position, inject PUR, fixing 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, bore 4 apertures at pit shaft 1 near one side of perforate, the reinforcing bar of 2 intersections is installed, in mould, place the bar-mat 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 top, 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.
