Abstract

The utility model provides a special-shaped concrete drain tile conduct pipe which is integrally cast once by an upper wall, two side walls and a lower wall, wherein the upper wall is of cambered surface shape, the side walls are of flat surface shape, and the bottom surface of the lower wall is of approximate flat surface shape. The conduct pipe is arranged under the ground without rolling and displacement, the stability is good, thereby the watertightness of the conduct pipe interface is ensured. Compared with the conduct pipe with the same diameter, the cross-section of the inner hole of the conduct pipe increases by 10%, and the drainability increases by10-20%, thereby the pipe material of the drain pipe network system is reduced greatly. The utility model is capable of canceling or saving the ground-work of the conduct pipes, thereby the integrated fabrication cost of the drain conduct pipe engineering is decreased greatly. The utility model is applicable to the drainage of the municipal rain-water and sewage water.

Description

A kind of abnormity concrete drainage pipe

Technical field:

The utility model belongs to outdoor drainage pipeline field.

Technical background:

The form of structure of the concrete drain pipeline of China did not change decades, inner-walls of duct and outer wall are circle, pipeline flows easily, poor stability, be laid on underground after because roll, displacement, cause pipe joint crack, dislocation and leak, the water that spills washes away the outer sand of pipeline along running off in the pipeline, and underground in the course of time formations cavity causes road to ftracture or subsides; The pipeline of outer wall circle when the earth backing backfill, the angle position of pipeline and trench bottom surfaces, it is closely knit and influence the workmanship of road to be not easy very much backfill; Taking under the identical condition of underground space height simultaneously, the cross-section of river is little, drain discharge is also little, the depth of burying of pipeline also will strengthen, not only increase cost, and wasted underground space resource, especially under the most valuable situation of the underground elevation in riverine and coastal city, not only drainage effect is greatly affected, and construction costs improves greatly.

Technology contents:

The utility model will solve pipeline in use, and poor stability is taking under the identical condition of the underground space height technical problem that the cross-section of river is little.

The technical solution of the utility model is: pipeline is cast by upper wall, two sidewalls and lower wall one piece, and upper wall is an arc surfaced, and sidewall is plane, and the lower wall bottom surface is roughly plane.

The upper wall of above-mentioned pipeline is that semi arch is planar.

The lower wall inner surface of above-mentioned pipeline is plane.

The lower wall inner surface of above-mentioned pipeline is the curved surface shape.

The lower wall inner surface of above-mentioned pipeline is V-shaped.

Be connected by the arc-shaped curved surface transition between the sidewall of above-mentioned pipeline and the lower wall.

Be connected by chamfered transition between the sidewall of above-mentioned pipeline and the lower wall.

Between the two side of above-mentioned pipeline inner width on be wider than down wide.

Be wider than wide under the pipe outer wall of above-mentioned pipeline.

Tall and big in the pipe of above-mentioned pipeline in the pipe inner width.

The lower wall thickness of above-mentioned pipeline is more than or equal to upper wall thickness.

Beneficial effect: the utility model is laid in underground rear stability can be good, is difficult for rolling, and is difficult for displacement, guaranteed that pipe joint is water-tight; It is about 10% that the bore profile of pipeline increases, and under the condition of identical degree of filling, the water passing capacity of pipeline increases by 10%～20%; Save buried depth of pipeline, saved the underground space simultaneously; The pipeline material of sewerage pipeline network is significantly reduced; Make the backfill of tube circumference closely knit easily simple and durable more, guaranteed the construction quality of pipeline and the service life of road; Simultaneously can cancel the concrete duct basis, not only make pipeline construction become simple; And the integrated cost of reduction pipe works, reduce construction costs greatly.

The specific embodiment:

First embodiment: as shown in Figure 1, the utility model abnormity concrete drainage pipe is cast by upper wall, two sidewalls and lower wall one piece, and upper wall is an arc surfaced, and sidewall is plane, and the bottom surface of lower wall is plane.According to stress performance, it is planar that upper wall is made semi arch.The lower wall inner surface is plane.In order to improve the intensity between sidewall and the lower wall, its binding site is connected by the arc-shaped curved surface transition, also can be connected (as shown in Figure 2) by chamfered transition.In order to improve the stability of pipeline, pipeline outer wall following is wider than wide (as shown in Figure 2).In order to improve the force intensity that is subjected to of lower wall, reduce basis or cancellation basis, the thickness of lower wall is greater than the thickness of upper wall.

Second embodiment: the utility model in the specific implementation, the lower wall inner surface can be made curved surface shape (as shown in Figure 3).

The 3rd embodiment: the utility model in the specific implementation, the lower wall inner surface can be made V-arrangement (asking as Fig. 4), this embodiment can improve the flow velocity of current at low discharge, improves the self-purification capacity of pipeline.

The 4th embodiment: the utility model in the specific implementation, between the two side inner width on be wider than down wide (see figure 5) so that improve the flow velocity of current during low discharge, strengthen the intensity of sidewall simultaneously.

The 5th embodiment: the utility model in the specific implementation, the pipe inner height can be greater than the pipe insied width, between the two side inner width on be wider than down widely, in order to reduce concrete amount, manage the following wide of outer wall less than last wide (see figure 6).The thickness of lower wall is greater than upper wall thickness.
