Technical Field

The invention relates to a flexible interface pipeline buttress with a bottom sill, which prevents flexibility in the laying process of a flexible pipeline

The turning part of the sexual pipeline slips and overturns.

Background

The turning of the buried pipeline is a common engineering condition, and the flexible pipeline has the problem of easy slippage at a horizontal corner. The solution is generally to arrange concrete buttresses at the corners of the flexible pipe. The traditional concrete buttress has large concrete cubic volume and earthwork excavation volume, which can cause the increase of engineering investment.

In order to solve the problems of insufficient slippage resistance and overturning resistance of the flexible pipeline at a horizontal corner, the turning requirement of the flexible pipeline at any angle in the horizontal direction is met, the concrete cubic content and the earthwork excavation content are reduced simultaneously, and the flexible interface pipeline buttress with the bottom sill is arranged.

Disclosure of Invention

The invention aims to provide a flexible interface pipeline buttress with a sill, which can solve the problems of insufficient slippage resistance and overturning resistance of a flexible pipeline at a horizontal corner, and can reduce the concrete volume of the traditional concrete buttress and the earth excavation volume in the construction process, thereby reducing the construction cost.

In order to achieve the purpose, the technical scheme of the invention is as follows: the utility model provides a take flexible interface pipeline buttress of sill, includes concrete buttress, its characterized in that concrete buttress rear portion below sets up the sill, and the pipeline socket joint is established to the concrete buttress front portion, is equipped with the linoleum between concrete buttress front portion and the rear portion, will take the flexible interface pipeline buttress setting of sill at flexible pipeline turn, makes the area of contact of buttress rear portion back and soil body strengthen to make the stability reinforcing of buttress on only increasing the basis of the little part concrete.

Further, because the passive soil pressure of sill department is great, its width needs to satisfy simultaneously the intensity requirement of shearing and bending resistance, sill width is not less than 200mm, and height control is at 200mm ~1000mm, establishes the inclined plane between the bottom of sill and the concrete buttress bottom surface, and sill inclined plane and horizontal plane contained angle are not more than 45.

Further, the pipeline socket comprises a flexible elbow, and pipeline interface ports are arranged at two ends of the flexible elbow so as to be connected with flexible pipelines at two sides.

The invention provides a flexible interface pipeline buttress with a sill, which utilizes the friction force between the buttress and soil and the pressure of the soil on the buttress to keep the stability of the pipeline in slippage resistance and overturning resistance. The invention has the advantages that the cubic content of the concrete buttress and the earthwork excavation amount in the construction process are reduced on the premise of meeting the requirements of anti-slip and anti-overturning stability of pipeline turning, thereby reducing the engineering investment and being a one-time structural innovation of the concrete buttress.
