Abstract

The invention discloses a large-diameter composite butt and strap joint rainwater pipe system and a construction method. The rainwater pipe system comprises rainwater pipes, wherein the bottoms of therainwater pipes are located and fixed by two bases; a plain concrete cushion layer and a flexible cushion layer are sequentially paved on the lower surfaces of the bases; the upper surfaces of the rainwater pipes are pressed and locked by an arc-shaped lock; the upper surfaces of the rainwater pipes are covered by cellular concrete and the upper sides are back-filled with plain soil; and the construction method comprises the following construction steps: construction preparation, construction layout, pipe trough excavating, cushion layer construction, batten fixed tightening latch pre-buring,pipe base installation, rainwater pipe installation, separated butt and strap mold installation, applying cement mortar to the butt and strap, butt and strap maintenance, calking groove treatment, installing vertical supporting ribs and the like. The structure (the rainwater pipe system) provided by the invention is convenient to mount and dismount; the rainwater pipes can be located with high precision; the rainwater pipes, which are free from disturbance in a butt-joint process, are good in stability; and the butt and strap are good in waterproofing effect and can adapt to rainwater and sewage pipelines that foundation soil is relatively poor, foundation hardness is uneven or located in earthquake areas; therefore, relatively good economic and technical benefits are achieved.

Description

Technical field [0001] The invention relates to a large-diameter composite wiping belt interface rainwater pipe system and a construction method for poor foundation soil, uneven foundation hardness or seismic areas. Background technique [0002] The rainwater pipe is the main structure that undertakes the drainage function. It is a combined structure composed of precast concrete, reinforced concrete or prestressed pipes and cast-in-place concrete foundation. The rainwater pipeline is buried underground. It is a concealed project and must have sufficient mechanical strength. Therefore, the pipeline interface must be made of dense and impermeable material, and has the ability to resist erosion, and the inner wall of the pipeline is required to be smooth and flat. [0003] Rainwater pipelines often have the following quality problems during the construction process: 1) The rainwater pipeline interface is wiped with hollows, large cracks, and serious water leakage. 2) Reverse slope of...
