Description
Technical field
The utility model belongs to water feeding and draining device and manufactures processing technique field, relates to specifically a kind of power station collector drain stationary hopper plastic downpipe joint, for using when massif draining in tunnel.
Background technology
Existing is to adopt plug-in type to connect for the downpipe joint using when massif draining in tunnel, insert and be reserved in the preformed hole of tunnel massif by leader, fix by inserting the elastic caoutchouc integument of massif downpipe joint (being threaded) and the friction of massif preformed hole inwall, then use platen (being threaded) to inserting the elastic caoutchouc integument extruding of massif, make it tight with massif extruding around, anti-sealing oozes out from leader outside.
There is following defect in above-mentioned prior art: 1, because existing overboard pipeline is to adopt plug-in type to connect, insert and be reserved in the preformed hole of tunnel massif by leader, and realize fixing by inserting the elastic caoutchouc integument of massif downpipe joint and the friction of massif preformed hole inwall, this technology easily causes downpipe joint to come off, the 2nd, if drainage hole is lost circle (due to drilling technique horizontal constraints, cause massif outfall cross section), easily cause having gap between elastic caoutchouc integument and massif, easily cause percolating water to expose.2, because percolating water in tunnel massif exists a large amount of Ca, Mg plasma panel, easily cause stopping up after discharge pipe line fouling, pipeline dredging is inconvenient, causes discharge pipe line to lose efficacy.3, above-mentioned prior art scheme can cause the perforate of tunnel massif drain hole larger, and causing investing total cost increases, and cost is higher.
Summary of the invention
The purpose of this utility model is the weak point in order to overcome background technology, and a kind of power station collector drain stationary hopper plastic downpipe joint is provided.
To achieve these goals, the technical solution of the utility model is: power station collector drain stationary hopper plastic downpipe joint, it is characterized in that: its downpipe joint for being connected by injection mo(u)lding and with the drain hole of massif, described downpipe joint comprises that centre is provided with the location-plate of through hole, filler tube, and outlet pipe; Described filler tube upper end is communicated with location-plate, and filler tube lower end is communicated with outlet pipe, and location-plate is provided with the screwed hole that multiple intervals are evenly arranged.
Described screwed hole has four.
In technique scheme, the number of screwed hole is take four as good.
Described outlet pipe comprises the first outlet pipe and the second outlet pipe that link together, and the angle between described the first outlet pipe and the second outlet pipe is 90～180 °.
In technique scheme, in the time that outlet pipe is broken line type, outlet pipe is draining more fast, reduces the probability of fouling, and makes practicality of the present utility model stronger.
Described the first outlet pipe, the second outlet pipe, filler tube and location-plate are structure as a whole.
In practical work process, the utility model requires tunnel surface relatively more smooth at installed position, without obvious protrusion, and need between massif drain hole place and downpipe joint, install when mounted an elastic caoutchouc pad additional, play sealing function, prevent in massif drain hole that water is from downpipe joint seepage.In the time selecting downpipe joint, can suitably select tunnel massif drain hole bore to be slightly less than bell mouth internal diameter, can prevent in drain hole that percolating water is from downpipe joint seepage as far as possible.
To sum up, the utility model is simple in structure, easy for installation, and structural stability is higher, and cost is lower, not only can effectively prevent that downpipe joint from coming off, and favorable sealing property.

1-screwed hole in figure, 2-location-plate, the through hole in 21-location-plate centre, 3-filler tube, 4-outlet pipe, 41-the first outlet pipe, 42-the second outlet pipe, 5-downpipe joint.
The specific embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not form to restriction of the present utility model, only for example.Make advantage of the present utility model more know and easily understand by explanation simultaneously.
Consult accompanying drawing known: power station collector drain stationary hopper plastic downpipe joint, it is characterized in that: its downpipe joint 5 for being connected by injection mo(u)lding and with the drain hole of massif, described downpipe joint 5 comprises that centre is provided with the location-plate 2 of through hole 21, filler tube 3, and outlet pipe 4; Described filler tube 3 upper ends are communicated with location-plate 2, and filler tube 3 lower ends are communicated with outlet pipe 4, and location-plate 4 is provided with the screwed hole 1 that multiple intervals are evenly arranged.
In practical work process, the utility model requires tunnel surface relatively more smooth at installed position, without obvious protrusion, and need between massif drain hole place and downpipe joint, install when mounted an elastic caoutchouc pad additional, play sealing function, prevent in massif drain hole that water is from downpipe joint seepage.In the time selecting downpipe joint, can suitably select tunnel massif drain hole bore to be slightly less than bell mouth internal diameter, can prevent in drain hole that percolating water is from downpipe joint seepage as far as possible.
Described screwed hole 1 has four.Described outlet pipe 4 comprises the first outlet pipe 41 and the second outlet pipe 42 that link together, and the angle between described the first outlet pipe 41 and the second outlet pipe 42 is 90～180 °.Described the first outlet pipe 41, the second outlet pipe 42, filler tube 3 and location-plate 2 are structure as a whole.
As depicted in figs. 1 and 2, the utility model can all use polyvinyl chloride or similar plastics to process, be connected to leader top, installation, dredging and detaching pipelines all more for convenience, and can effectively solve because of massif drain hole circle cause gutter leakage problems.
In practical work process, before installation downpipe joint, should first check that whether massif drain hole surface is smooth, if out-of-flatness, can adopt the electric toolss such as angle grinding machine to polish processing to its surface, if install in irregular situation, the one, easily cause the easy impaired destruction of elastic caoutchouc pad, the 2nd, may cause percolating water in drain hole to ooze out from funnel top edge, affect drainage effect.Secondly should adopt electric drill etc. according to holing downpipe joint tap bolt mouth position, this bore dia should be slightly less than screwhole diameter, to can adopt tap bolt firmly to fix downpipe joint.
When mounted, first elastic caoutchouc pad is placed between massif drain hole and downpipe joint, and to the screw between good three, adopts (stainless steel) tap bolt that downpipe joint is fixed.Then the various pipelines such as bellows or pvc pipe that adopt match with downpipe joint water outlet pipeline (internal-and external diameter on main vial road), are tightly connected leader delivery port and gutter, and construction quality should guarantee that joint is water-tight.Finally employing pipe clamp is fixed on gutter on tunnel body of wall, gutter is caused to the gutter of appointment or catchments a little.
