Description

The multitube that pipe top the flushes manhole that confluxes

Technical field

The utility model relates to pipeline and manhole technical field, the multitube that especially a kind of pipe top the flushes manhole that confluxes.

Background technology

Along with the propelling that urbanization is built, requiring of the reasonable laying of the pipe network of cities and towns plumbing and other FLUID TRANSPORTATION is increasingly high.It is the raw material once injection moulding that plastic inspection well adopts macromolecule resin, and split combines, and is easy to use, and convenient maintenance and maintenance from now on become the cities and towns water supply and sewerage pipeline and built requisite unit.The laying difficulty of special cities and towns rain effluent discharge pipe network is bigger, has slightly irrationally bring numerous worries will for daily life from now on.Manhole rational in infrastructure can bring a lot of facilities to daily life, and once construction is non-maintaining for a long time.But there is more irrational place in the laying of plastic inspection well of the prior art and pipeline thereof, the setting of ordinary circumstance trunk line be the upper reaches a little more than downstream so that Water seeks its own level, emission effect is better.The access port that connects various blowdowns or branch drain road on the trunk line; Sewage in the branch pipe(tube) confluxes into and is discharged to Sewage Disposal behind the trunk line; Because plastic inspection well is that the one injection moulding is accomplished, in the prior art for ease of modeling, the center line that generally adopts trunk line and branch pipe(tube) same horizontal plane mentality of designing; Mould is simple like this, makes simple.But phenomenon can appear pouring in down a chimney in the branch pipe(tube) in this structure downstream when the discharge of sewage is big, has a strong impact on the blowdown drainage effect.The caliber of existing branch pipe(tube) is generally 75mm, 110mm, 160mm, 200mm, and the pipeline of every kind of caliber is suitable for different blowdowns to be needed.Two bellmouths that are connected trunk line on manhole comprises pit shaft, well seat and is arranged on the well seat; Upper wellbore is provided with manhole cover base and well lid; Also be provided with the branch pipe(tube) interface on the well seat, the diameter of this interface needs to design in advance according to actual conditions, to reduce the pipeline situation not corresponding with interface.But the actual caliber of pipeline that uses is different, is difficult to add up the back in advance and makes processing to various pipelines, and the manufacturing cycle prolongs greatly, is unfavorable for product lot quantity production, and cost is higher.Even each manhole to occur all be a non-tender, and each all needs designing mould again, processing again, and difficulty is bigger, and efficient reduces, and cost is high.

The utility model content

The technical problem that the utility model will solve is: in order to solve deficiency of the prior art; The utility model provides a kind of pipe multitube that the top the flushes manhole that confluxes; Adopt the structure of the coaxial setting of union of three kinds of the most frequently used specifications to help making in batches, construction is more simple and convenient during use; When flow is big and can prevent that downstream from pouring in down a chimney.

The utility model solves the technical scheme that its technical problem adopted: the multitube that a kind of pipe top the flushes manhole that confluxes; The bellmouth that is connected trunk line on comprising pit shaft, well seat and being arranged on the well seat; Pit shaft is provided with manhole cover base and well lid; Also be arranged with the joint at least two connecting branch roads on the trunk line in parallel; Described joint comprises the pipeline bellmouth that fuses with trunk line, the coaxial union that two or three calibers in an aperture, mesopore, the macropore are set on the pipeline bellmouth, and the center line of described union is positioned at the top of well seat 2 center lines.

The coaxial union that an aperture, a mesopore, three calibers of a macropore are set on the described pipeline bellmouth, wherein the upper limb of the union of macropore caliber flushes with well seat upper limb.

The union of the macropore caliber in described adjacent two joints overlaps and is provided with.

Between adjacent pipe joints, be provided with the groove that the union of being convenient to little caliber is removed on the described base plate.

The caliber of the union of described aperture caliber is 110mm, and the caliber of the union of mesopore caliber is 160mm, and the caliber of the union of macropore caliber is 200mm.

The beneficial effect of the utility model is, the multitube that the pipe top of the utility model the flushes manhole that confluxes is novel; Adopt the coaxial setting of union of the most frequently used 110mm, 160mm, 200mm caliber; Can be according to job site actual needs field machining, simple to operation, this structure more helps manufacturing in enormous quantities; Thereby reduce production costs, reduce the production cycle; The upper limb of the union of maximum caliber flushes with well seat upper limb, and when making blowdown or draining, the depth of water is deepened to form and fallen, and has improved the blowdown drain discharge, has solved the problem that pour in down a chimney in downstream.
