重力排蓄式拱形种植屋盖构造系统
By designing a gravity-drainage arched green roof system, rainwater is collected using the arched roof and expanded clay drainage layer, solving the problem that traditional roof structures cannot effectively utilize rainwater. This achieves rainwater collection and slow infiltration, improving architectural aesthetics and urban environmental quality.

AI Technical Summary
Under the traditional urban construction model, hardened roads and reinforced concrete buildings have poor water retention capacity, leading to frequent flooding during heavy rains. Existing roof structures cannot effectively collect and utilize rainwater, lacking the functions of sponge buildings.
A gravity-fed arched planting roof system is designed, using an arched roof as a carrier, forming a rainwater infiltration channel through the arch ring, combined with a ceramsite water storage layer, infiltration drainage pipes and planting soil, to achieve rainwater collection and slow infiltration, and to utilize rainwater resources through reverse irrigation.
It achieves effective rainwater collection and utilization, reduces urban flooding pressure, enhances the aesthetic value of buildings, and has the effects of water conservation, energy saving and emission reduction, meeting the requirements of sponge city construction.

Abstract
Claims
1. A gravity drained arched planting roof construction system characterized by, The system includes an arched roof and supporting beams of a steel structure connected to the arched roof. The arched roof is composed of multiple connected arches, with a ditch formed between adjacent arches. The curved surface of the arches serves as a rainwater infiltration channel, and the ditch serves as a rainwater collection channel. A ceramsite drainage / water storage layer is arranged inside the ditch, and an infiltration drainage / water storage pipe is located inside the ceramsite drainage / water storage layer. Above the ceramsite drainage / water storage layer is a geotextile filter, and above the geotextile filter is planting soil for planting vegetation.
2. The gravity drained arched planting roof construction system according to claim 1, wherein, The supporting beam and the arched roof are integrally cast and connected together.
3. The gravity drained arched planting roof construction system according to claim 1, wherein, The supporting beam includes a main beam and a secondary beam cast integrally with the arched roof. The main beam includes a first main beam and a second main beam arranged perpendicular to the first main beam. The first main beam and the secondary beam are arranged on the upper surface of the second main beam. There are two first main beams. The secondary beams are parallel to the first main beams and are located between the two first main beams. Each secondary beam corresponds to a ditch above it.
4. The gravity drained arched planting roof construction system according to claim 3, wherein, The first main beam is connected to two load-bearing columns on both sides of the arched roof. Each first main beam corresponds to one load-bearing column and is perpendicular to the support direction of the load-bearing column.
5. The gravity drained arched planting roof construction system according to claim 3, wherein, Both the main beam and the secondary beam of the supporting beam are I-beams.
6. The gravity drained arched planting roof construction system according to claim 1, wherein, The top surface of the arched roof has a waterproof layer.
7. The gravity drained arched planting roof construction system according to claim 6, wherein, The waterproof layer includes a first waterproof layer and a second waterproof layer, wherein the second waterproof layer is a root-penetration resistant waterproof layer.
8. The gravity drained arched planting roof construction system according to claim 7, wherein, The waterproof layer is located beneath a leveling layer.
9. The gravity drained arched planting roof construction system according to claim 1, wherein, The infiltration / storage pipe is connected to the drainage blind pipe via a pre-buried drainage pipe, and the drainage blind pipe is connected to the vertically arranged pre-buried water collection pipe.
10. The gravity drained arched planting roof construction system according to claim 9, wherein, The pre-embedded water collection pipe is pre-installed inside the load-bearing column of the arched roof, and the pre-embedded drainage pipe is pre-installed inside the structure below the sill of the arched roof.
