Summary of the invention
For addressing the above problem, the present invention provide a kind of simple, short construction period of constructing, harbour airport not to stop transport not suspend construction, be difficult for glass fiber reinforced plastic metal composite well and well construction method aging, light and that be convenient to install.
For reaching above-mentioned purpose, the compound well of glass fiber reinforced plastic of the present invention comprises well body and well lid, and well body top is provided with well head; Said glass fiber reinforced plastic metal composite well also comprises walling crib; Said walling crib comprises with the suitable foundation ring of said well head and is arranged on top, said foundation ring and the suitable joint portion of said well lid; Said foundation ring is detachably connected on the said well head; Said well lid covers on the said foundation ring of inboard, said joint portion, and well lid sidewall and said joint portion fit; Wherein, said well body is a glass fiber reinforced plastic well body; Said walling crib is metal walling crib or alloy walling crib; Said well lid is metal well lid or alloy well lid.
Preferably, said outer wellhead is along being provided with and the integrated sub-flange of said well head; Said foundation ring is positioned at said joint portion Outboard Sections, is provided with and the suitable female flange of said sub-flange; Said walling crib is connected for the flange plate type bolt with said glass fiber reinforced plastic well body.
Preferably, said joint portion is connected side with said well lid, spends greater than 90 with the angle of said foundation ring; And it is consistent with said well lid sidewall slope angle size.
Preferably, on said foundation ring,, be provided with the damping cushion rubber with said well lid back side touching position.
Preferably, said well lid surface to lower recess, cooperates the formation aprons slot along outward flange with said joint portion; In said aprons slot, dustproof cushion rubber is installed; The width of said dustproof cushion rubber is greater than the width of said aprons slot; Through extruding said dustproof cushion rubber is put into said aprons slot, form sealing ring.
Preferably, said well lid surface is provided with non-slipping block or anti-skidding muscle; The said well lid back side is provided with ribs; Said ribs is ring-type ribs or radial ribs.
Preferably, said glass fiber reinforced plastic well body comprises monolithic and segmented, and said segmented well body adopts bayonet joint between two sections well bodies, is sealed in the junction by cushion rubber.For reaching above-mentioned purpose, well construction method of the present invention may further comprise the steps:
Step 1: offer well slot from the face of land downwards;
Step 2: the compound well of above-mentioned glass fiber reinforced plastic is put into said well slot;
Step 3: utilize adhesive, concrete or earth to fill the gap between said well slot and the compound well of said glass fiber reinforced plastic, the smooth face of land.
Further, the height of said well slot is not less than the height of said glass fiber reinforced plastic well body.
Characteristics such as wherein, glass fiber reinforced plastic is existing a kind of functional new material that is composited by synthetic resin and glass fiber, and is anticorrosive, light.
The beneficial effect of this practical glass fiber reinforced plastic metal composite well and well construction method:
1, glass fiber reinforced plastic metal composite well of the present invention and well construction method; The compound well of glass fiber reinforced plastic is produced in advance; When construction, only need the compound well of glass fiber reinforced plastic is put into the well slot that has installed hydrant or valve well pipeline in advance; Banket or filling adhesive and smooth good ground, promptly accomplished the construction of whole well; It is simple to have construction sequence, the characteristic of short construction period.With respect to the traditional concrete pouring, the engineering time is long, also needs the quite a while to treat the well soma after the construction, can be with load capacity; Reduce the difficulty of construction greatly, shortened the engineering time.On the aerodrome, can realize the construction of not suspending, at harbour, can realize the construction of not stopping transport, do not influence other construction operations of construction plant.
2, glass fiber reinforced plastic metal composite well of the present invention, because glass fiber reinforced plastic well body, metal or alloy walling crib and well lid all are by plant produced, the finished product after the production through the systematization detection of factory, can be guaranteed the big or small to bearing load of product, performance requirements such as sealing.With respect to the well of site operations such as traditional brick, concrete, because the Effect of Environmental such as human factor and ground of construction are arranged, the bearing load size of well body, the stability of each side such as sealing is not enough.After the construction, pinpoint the problems and to construct again or to study for a second time courses one has flunked, influence the normal operation on duration and airport, harbour and road surface.
