Embodiment 1

[0037] Example 1: as figure 1 As shown in the figure, the present invention can be applied not only to new buildings, but also to renovation and renovation of roof drainage systems of existing buildings. When applied to a new building, when pouring concrete on a flat roof, reserve the position of the concave mouth 111 of the combined gutters 1 in advance in the corresponding parts of the gutters, and wait until the concrete around the periphery of the concave mouth 111 is poured and hardened. After that, the solar power generation panel 5 and the attached cable 11, the power control switching device 51, etc. are installed on the flat roof. In the concave opening of the combined gutters 1, lay the thermal insulation reflection layer 7, after the laying is completed, arrange and lay the heating cables 6 with the approximate center of the 3 water inlets. Then vibrated, scraped, plastered, and calendered. After the curing of the bean stone concrete 8 is completed, the water inle...

Embodiment 2

[0040] Embodiment 2: As shown in Figure 2, the shape of the water inlet protective cap 2 in the figure is a combination of a conical shape and a cylindrical shape, the outer side of the conical shape is provided with a protective cap waterproof layer 21, and the lower layer of the protective cap waterproof layer 21 is provided There is a reflective arc panel 22; the water inlet grille 23 is a cylindrical sheet-like structure, which is spaced with water inlet holes, and the inside of the water inlet grille 23 is also nested with a slightly smaller diameter, which can be passed through. The water inlet grille sealing door 27 with a cylindrical sheet-like structure is rotated by the vertical axis of the center of the circle. The water inlet sealing door 27 is spaced with water inlet holes of the same size as that on the water inlet grille 23; the water inlet protective cap 2 is vertical A lift rod 25 is arranged at the axis position, a temperature-controlled electromagnetic switch...

Abstract

The invention discloses an anti-icing rainwater pipe system suitable for northern flat roofs and a working method, which belong to the technical field of construction engineering. It includes a combined eaves ditch, a water inlet protective cap, a water inlet, a composite rainwater pipe, a solar power panel, a heating cable, a thermal insulation reflective layer, a bean stone concrete, a rainwater pipe pipe clip, a building main body and a cable. The upper part of the gutter is provided with a concave opening, the upper surface of the concave opening is pasted with a thermal insulation reflection layer, a heating cable is laid above the thermal insulation reflection layer, and the outer side of the heating cable is backfilled with bean stone concrete; The upper part is provided with a protective cap for the water inlet, and the lower part is installed in the composite rainwater pipe; the buried depth of the composite rainwater pipe outlet is greater than the corresponding elevation of the maximum frozen soil depth. The structure is simple, and the gutter and rainwater pipes can be prevented from freezing, and the service durability is significantly improved.

Description

technical field [0001] The invention relates to a rainwater pipe system and a working method, in particular to an anti-icing rainwater pipe system and a working method suitable for northern flat roofs used in northern buildings, and belongs to the technical field of construction engineering. Background technique [0002] In the vast areas of northern my country, the temperature in winter is relatively cold, and rain and snow in winter are more common. After the rainy and snowy weather in winter, when the temperature is high during the day, the rain and snow will melt, but the temperature will drop at night, and the temperature at night will often drop below zero. Generally, the icing on the gutter cannot be quickly melted and discharged to the drainage ditch. Often, under the action of the freeze-thaw cycle during the day, the concrete on the upper surface of the gutter is always under the erosion and damage of ice water, which often causes the concrete on the upper surface ...
