Abstract
The utility model discloses a combined type banded plastic pipe and concrete inspection well. The inspection well comprises a combined shaft (1); a plastic wall pipe (2) is used as an inner later; concrete is poured into an outer wall to form an outer wall of the shaft; the combined shaft and a foundation (4) are matched; the foundation is provided with an embedding positioning device which is matched with the combined shaft; the shaft wall of the combined shaft is provided with a group of water feeding and draining holes which are connected with branch pipes; and the plastic wall pipe is wound in a band shape and is extruded on a machine by using a die to form a pipe shape. The formed compounded type drain pipeline inspection well has the smoothness of a plastic acid and alkali-resisting well wall and the intensity of concrete, and can also be formed in a factory and installed at site.
Description
Technical field
The utility model relates generally to the manhole of a kind of municipal sewage system, particularly sewer.
Background technology
The sewer manhole of existing urban construction draining, blowdown, generally encouraging to adopt plastic inspection well in the residential quarter, is corrosion-resistant because of it, acid and alkali-resistance, lightweight, long service life, easy construction discharges fast etc., but the manhole that pure plastic pipe is done, anti-vertical load and soil pressure are limited in one's ability, and brick manhole, country bans use of.Concrete inspection well only is used for diameter large, usually surpasses 700mm, and requirement of strength is high, and service time is long, the place that voltage endurance capability is strong, but its construction period is longer, affects construction speed, but change powder, anti-corrosion capability deficiency are easily peeled off in permanent use.
The utility model content
The purpose of this utility model is to provide a kind of can overcome the known technology shortcoming, and connection easy for installation is reliable, can use for a long time, and is corrosion-resistant, a kind of combined plastic concrete inspection well of acid and alkali-resistance.
For achieving the above object, scheme of the present utility model is: described manhole comprises a combination pit shaft, utilize mould to make internal layer at the plastic wall pipe of the bonding one-tenth tubulose of machine extruding by banded a winding, the outer wall casting concrete forms the pit shaft outer wall, described combination pit shaft cooperates with a base, and base is provided with and the chimeric positioner that makes up pit shaft and cooperate, and has one group for entry on the barrel of combination pit shaft, the hole of draining, the hole is connected with arm.
Adopt such scheme, formed compound sewer pipe manhole both to have a plastics acid and alkali-resistance borehole wall smooth, have again concrete intensity, and can in factory's moulding, install at the scene, thereby realize the purpose of this utility model.
Below in conjunction with diagram and embodiment scheme is described in more detail.
Description of drawings
Fig. 1 is the front view of the banded plastic pipe concrete inspection well of a kind of combined type;
Fig. 2 is the making sketch of banded plastic pipe among Fig. 1.
The specific embodiment
As described in Figure 1, described manhole comprises a combination pit shaft 1, described combination pit shaft has a plastic wall pipe 2, the shell 3 that the outside has a concrete casting to form, combination pit shaft 1 is installed on the base 4, the flange collar 5 that the surface of base has plastics to form, the bottom of the chimeric formation combination of the endoporus pit shaft of described flange collar and combination pit shaft, the following casting concrete round platform 6 of flange collar 5, and be slightly larger than the diameter that makes up pit shaft.
Have one group of hole on the combination pit shaft, by the hole two arms 7 are installed, certainly the number of arm is not limited to two, should decide according to designing requirement, two Zhi Guanyong plastics make, after arm is in place, the end of arm is connected with firm welding with the plastics of the tapping of combination pit shaft, can fills out around arm with concrete in the erecting bed and reinforce.
The combination pit shaft is formed by more piece, and the two ends of each joint form the setting element that is connected with its joint, select as required at the scene quantity, are added with well lid 8 at pit shaft.
The said plastic pipe of the technical program is the PE structural tube, and its making comprises that with high density polyethylene (HDPE) be raw material, adds the glass fiber banburying, be extruded into ribbon 9 through extruder, be wound in again tubular body, utilize mould 10 on machine through extrusion modling, form a large diameter PE structural tube, this tubing pliability is good, life-span is long, and is lightweight, anticorrosion, anti-corrosion performance is strong, and lower temperature resistance and low-temperature impact property are good.
The plastic inspection well of this programme has easy for installation, reliable in quality, and the characteristics of product specification are the reforms that municipal sewage system is built, and in process on probation, are subject to the general welcome of user.
Claims (2)
1. the banded plastic pipe concrete inspection well of a combined type, it is characterized in that: described manhole comprises a combination pit shaft (1), utilize mould to make internal layer at the plastic wall pipe (2) of the bonding one-tenth tubulose of machine extruding by banded a winding, the outer wall casting concrete forms the pit shaft outer wall, described combination pit shaft cooperates with a base (4), and base is provided with and the chimeric positioner that makes up pit shaft and cooperate, and has one group for entry on the barrel of combination pit shaft, the hole of draining, the hole is connected with arm.
2. the banded plastic pipe concrete inspection well of a kind of combined type according to claim 1 is characterized in that: make up pit shaft (1) and formed by more piece, the setting element that the two ends formation of each joint is connected with its joint.
