Abstract
The invention relates to the field of spiral winding pipes, in particular to a steel-plastic glass sand composite winding pipe. The steel-plastic glass sand composite winding pipe is designed mainly for solving the problem that an existing spiral winding pipe has a strict requirement for backfilling when installed on site. The steel and plastic glass sand composite winding pipe is formed by winding forming boards. Each forming board comprises a pipe wall. The two ends of each pipe wall are provided with a lock catch and a lock groove respectively. Glass fiber reinforced plastic layers are arranged outside the pipe walls and fixed to the tops of the lock grooves. The space between the pipe walls and the glass fiber reinforced plastic layers is filled with sand. Reinforcing ribs are arranged between the pipe walls and the glass fiber reinforced plastic layers. The two sides of the upper end of each lock groove are provided with grooves. Each reinforcing rib is composed of a plurality of U-shaped ribs and connecting ribs, wherein every two adjacent U-shaped ribs are connected through one connecting rib. Each reinforcing rib is arranged between two adjacent lock grooves, and the two ends of each reinforcing rib are clamped in the grooves in the upper ends of two adjacent lock grooves respectively. Pipe wall reinforcing ribs are arranged on the pipe walls, and the tops of the pipe wall reinforcing ribs make contact with the lower surfaces of the connecting ribs. The space between the glass fiber reinforced plastic layers and the U-shaped ribs of the reinforcing ribs is filled with sand. The steel-plastic glass sand composite winding pipe has the advantage that the requirement for backfilling can be lowered.
Description
Technical field:
The present invention relates to spiral winding pipe field, specifically relate to a kind of steel and mould glass sand composite winding pipe.
Background technique:
Existing spiral winding pipe is all wound around by sheet forming and makes.The patent No. is 200820010331 disclose a kind of steel plastic compount wound drain pipe, its sheet forming comprises tube wall, tube wall both sides establish snap close and locked groove respectively, tube wall also establishes several strengthening rib equably, groove is established in the both sides of strengthening rib and locked groove upper end, between adjacent strengthening rib and between strengthening rib and locked groove, establish U-shaped steel rib, the suitable for reading of U-shaped steel rib is stuck in the groove of strengthening rib or locked groove.This steel plastic compount wound drain pipe hurts tube wall to prevent when installing at the scene, so require strict to backfilling working.In addition when entwining tube length large (12 meters), loading-unloading vehicle misoperation, can fracture entwining tube.
Summary of the invention:
It is low to backfilling working requirement that technical problem to be solved by this invention is to provide a kind of site operation, and glass sand composite winding pipe moulded by not easily damaged steel.
Above-mentioned purpose is achieved in that it is entwined by sheet forming, and described sheet forming comprises tube wall, and the two ends of tube wall are respectively equipped with snap close and locked groove; It is characterized in that: at tube wall peripheral hardware frp layer, frp layer is fixed on locked groove top.
Also can fill sand between tube wall and frp layer.
Also can establish stiffening rib between tube wall and frp layer, groove is established in the both sides of locked groove upper end, stiffening rib is made up of with the connecting tendon being connected two adjacent U-shaped muscle several U-shaped muscle, described stiffening rib is located between two adjacent locked grooves, and the two ends of stiffening rib are stuck in the groove of adjacent two locked groove upper ends.
Can also establish tube wall stiffening rib on tube wall, the top of tube wall stiffening rib contacts with connecting tendon lower surface.
Also can fill sand in the space between frp layer and the U-shaped muscle of stiffening rib.
Advantage of the present invention is: owing to being provided with frp layer at sheet material outermost, so when constructing backfill, frp layer can protect tube wall, can reduce the requirement to backfilling working, simplify job specfication, leakage proof better effects if.Between frp layer and tube wall, fill sand in addition, and be provided with stiffening rib and tube wall stiffening rib, ring stiffness and the bearing capacity of entwining tube can be increased.
Accompanying drawing illustrates:
