清扫透水铺装表层，恢复渗水能力：浙江省杭州市拱墅区城北体育公园 | Sweep the permeable paving clear so it can take water again: Chengbei Sports Park, Gongshu District, Hangzhou, Zhejiang.

透水铺装靠孔隙把雨水吃进地下，孔隙被泥沙、落叶和苔藓封住以后，这块地面和普通水泥地没有区别，雨天照样积水。清扫是唯一让它重新工作的日常动作。现场：浙江省杭州市拱墅区城北体育公园。以运动场地为主的社区公园，透水铺装与雨水口分布在活动区周边。 | English: Permeable paving only works while its pores are open. Once silt, leaf fall and moss seal them, the surface behaves like ordinary concrete and ponds in the rain. Sweeping it out is the one routine act that puts it back to work. Site: Chengbei Sports Park, Gongshu District, Hangzhou, Zhejiang. A community sports park where permeable paving and inlets ring the activity areas.

Pay

$130 proposed

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

作业前后照片 + 清扫面积 + 渗水秒数 + GPS点位 | before and after photos + area swept + soak-away seconds + GPS pin

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Steps

1. 1. 沿铺装区走一遍，用粉笔或标记桩标出积泥、生苔和明显不渗水的位置，并拍下作业前照片。 | Walk the paved area, mark the silted, mossy and visibly non-draining patches with chalk or pins, and photograph the as-found surface.
2. 2. 用硬毛刷和手推扫帚把表层泥沙、落叶和苔藓刷起来，从铺装外缘向内推，避免把泥推进孔隙。 | Lift the surface silt, leaf fall and moss with a stiff brush and push broom, working from the outer edge inward so nothing is pushed deeper into the pores.
3. 3. 把刷下来的泥沙落叶收进容器带走，不要冲进雨水口。 | Collect the swept silt and leaf fall into a container and carry it away, never flushing it into a stormwater inlet.
4. 4. 用一瓶清水缓慢倒在原来最不渗水的一处，记录水完全渗下去所用的秒数。 | Pour one bottle of clean water slowly onto the worst previously non-draining patch and record how many seconds it takes to soak away.
5. 5. 拍摄作业后照片，登记清扫面积与渗水秒数，交给管养单位。 | Photograph the finished surface and log the area swept and the soak-away seconds for the maintenance unit.

What counts as done

• 积泥或生苔处的作业前照片 | Before photo of the silted or mossy patch
• 同一位置清扫后的照片 | After photo of the same patch swept clear
• 清扫面积(平方米) | Area swept in square metres
• 倒水后完全渗下去所用秒数 | Seconds for the poured water to soak away

Proof is measured against these, not judged by taste.

The standard this serves

Green Stormwater Infrastructure. Green stormwater infrastructure is the city's way of handling rain the way a meadow does: rain gardens, planted swales, and permeable pavement that let a storm soak in instead of surging down a pipe. The EPA's inspection standard keeps these systems honest, because a neglected rain garden quietly stops working while still looking like a garden. Mastery is the inspector's eye: reading inlets, overflow, plants, and soil in a single practiced pass. This packet is one such inspection, one basin checked and one record filed, which is precisely how a thousand basins stay alive.
