As shown in fig. 2, wherein be equipped with a plurality of concave shape mouths 111 on novel eaves gutter 1, perhaps concave shape mouth 111 size matches with novel eaves gutter 1, and a plurality of concave shape mouths 111 or match the inherent novel eaves gutter 1 that is equipped with a plurality of water inlets 3 on the concave shape mouth 111 of size with novel eaves gutter 1, it is corresponding, be equipped with the compound downspout 4 that multichannel and water inlet 3 are connected, pre-buried steam heating pipe 5 sets up around water inlet 3 in concave shape mouth 111. One end of the embedded heating pipe 5 is connected with a water inlet pipe of the indoor heating pipe 10 through an embedded heating pipe inlet 11, and the other end of the embedded heating pipe is connected with a water return pipe of the indoor heating pipe 10 through an embedded heating pipe outlet 12.

As shown in fig. 3, the upper part of the water inlet protective cap 2 is a conical umbrella-shaped structure, the lower part of the water inlet protective cap is a cylindrical structure with a diameter smaller than that of the conical umbrella-shaped structure, a protective cap waterproof layer 21 is arranged on the outer side of the conical umbrella-shaped structure, and a stressed skeleton layer 21a and a reflective arc panel 22 are sequentially arranged below the protective cap waterproof layer; the cylindrical structure is provided with water inlet grilles 23 with sheet structures at intervals, and the water inlet grilles 23 are provided with water inlet holes at intervals.

The first embodiment is as follows: the utility model provides a pair of embodiment: the utility model provides a prevent drainage system that eaves gutter, downspout freeze suitable for pitched roof, as shown in figure 1, the utility model discloses before implementing, reserve in advance and be equipped with indoor heating pipe 10, the heating pipe in indoor heating pipe 10's one end and the building subject 9 links to each other, and the other end is pre-buried in the floor to the roof and extend to in the novel concavity mouth 111 of eaves gutter 1. As shown in fig. 2, in the concave mouth of novel eaves gutter 1, lay heat preservation reflection stratum 6, lay the completion back, with the 3 approximate centers in water inlet, arrange and lay pre-buried heating pipe 5, be connected respectively with pre-buried heating pipe 5 and form the return circuit with pre-buried heating pipe import 11, pre-buried heating pipe export 12 during laying, lay the completion back, pour pea stone concrete 7 in concave mouth 111, vibrate afterwards, strickle, plaster, press polish. After the curing of the pea stone concrete 7 is finished, a water inlet protective cap 2 is arranged above the water inlet 3. Subsequently, the composite storm sewer 4 is installed at a corresponding position of the outer wall of the building body 9, and the composite storm sewer 4 is fixed at intervals by the storm sewer pipe clips 8 during installation. It should be noted that, unlike the known and common rain pipe which is only installed above the outdoor water, the composite rain pipe 4 of the present invention is not exposed outdoors, as shown in fig. 1, and the buried depth needs to be buried below the corresponding elevation of the maximum frozen soil depth. The lowest part of a well-known and common rainwater pipe is usually arranged above an outdoor ground level, and a pipe opening is exposed, so that the pipe opening is usually frozen, when the freezing speed is higher than the ice melting speed, ice columns in the pipe continuously grow, the rainwater pipe is finally frozen tightly, and then the rainwater pipe is burst by the stored ice. The utility model discloses a compound downspout 4's export is direct pre-buried below the maximum frozen soil degree of depth corresponds the elevation, and its export is direct to be connected with 9 outdoor escape canals of building subject, and this ice and snow in having guaranteed compound downspout 4 when winter melts hydroenergy and smoothly in time gets rid of from the downspout, and it is smooth and easy to have guaranteed that the drainage of downspout is smooth and easy, has stopped the frozen possibility of downspout outlet pipe mouth department.

It is visible by the implementation of above-mentioned embodiment one, only need lay heat preservation reflection stratum 6, pre-buried steam heating pipe 5 then backfill pea stone concrete 7 in novel eaves gutter 1's concave mouth 111 in the work progress, install water inlet helmet 2 etc. in the top of water inlet 3 at last, above-mentioned whole construction simple process, the constructor of being convenient for operates, so the utility model discloses a novel drainage system is when implementing, and its human cost is lower, is convenient for popularize and apply on a large scale.

Example two: as shown in fig. 3, the shape of the water inlet protective cap 2 in the figure is a combination of a cone shape and a cylinder shape, the outer side of the cone shape is provided with a protective cap waterproof layer 21, and the lower layer of the protective cap waterproof layer is provided with a reflecting arc panel; the water inlet grille 23 is a cylindrical sheet structure, holes for water inlet are arranged on the water inlet grille at intervals, rainwater or melted snow water can be timely drained into the water inlet 3 in rainy and snowy weather, and further drained into the underground drainage system after being drained to the composite rainwater pipe 4.

After the construction of the drainage system for preventing the eaves gutter and the rainwater pipe of the pitched roof is finished, when the winter rain and snow weather occurs, a heating valve connected with the novel drainage system on the indoor heating pipe 10 is opened, and the temperature rises in the range above the concave opening 111 of the novel eaves gutter at the moment, so that the icing of the upper part of the novel eaves gutter is ensured, and the rain (snow) water energy is further ensured to be discharged in time; when the temperature was lower night in winter, because of the pre-buried heating pipe 5's in the novel eaves gutter 1 heating effect for novel eaves gutter 1 surface is not frozen, and simultaneously, the reflection cambered plate of water inlet helmet 2 is with the heat reflection of its below, the gathering in water inlet 3 tops, has guaranteed that water inlet 3 is not frozen. Because of having adopted compound downspout 4 in the example of the utility model, it is different from traditional PVC downspout, and the thermal insulation performance of its pipe self is better for the heat transfer outside of tubes is less. Furthermore, the composite rain pipe 4 is directly buried below the corresponding height of the maximum frozen soil depth, so that the cold and heat transfer between the lower opening of the traditional rain pipe and the outside is avoided, the temperature in the pipe is basically maintained above 0 ℃, and the phenomenon of freezing in the rain pipe is avoided.
