THE WOUND

01—08

From Ruins to Memorial Eco-park DATE: 2022.7~2022.10

SITE: Beirut, Lebanon

TYPE: academic work

CONCEPT: The Port of Beirut has a prosperous history, but as a result of a severe ammonium nitrate explosion, it has become a contaminated, scarred, and sgrieving site. The project aims to create a memorial eco-park that will both remediate the acidified contaminated soil and commemorate the horrific explosion, bringing the scarred site back to life.

Heihui River Channel Reconstruction DATE: 2023.7~2023.10

SITE: Shaxi, China

TYPE: academic work

CONCEPT: The water quality of Heili River is affected by urban domestic sewage and agricultural water, and the non-waterfriendly revetment design further alienates people from the river. This design aims to solve this problem through water purification and revetment design.

TWINKLING STARS

16—22

From Quarry To Observatory DATE: 2021.9~2022.1

SITE: Fujian, China

TYPE: academic work

CONCEPT: A city in Fujian is affected by light pollution and the stars cannot be seen. However, there is a quarry in the city which is far away from light pollution and has been abandoned for a long time. The project aims to transform this abandoned quarry into a unique star observatory through topographical design.

Coral Conservation Plan Near Stone Island SITE: Stone Island, Australia TYPE: academic work DATE: 2023.1~2023.3 CONCEPT: The coral near Stone Island, located in the middle of Australia's Great Barrier Reef, has been bleached by the heat island effect and sediment from cities and salt pans. This project aims to protect the coral through breakwater, sedimentation tank and an organic combination of tidal power generation and biorock.

A City With The Wound - Beirut, Lebanon The Location Of Beirut

35°29'25"

Beirut is the capital of Lebanon, facing the Mediterranean Sea. Behind and around it, the mountain ranges of Lebanon frame the city. Historically and today, the Port of Beirut has been a crucial part of Lebanese development and politics.

Strategy

Site Generation Process

The nitrogen dioxide and ammonia produced by the explosion of ammonium nitrate will form dilute nitric acid when exposed to rainwater, which will enter the soil and cause soil acidification together with the remaining ammonium nitrate.

Use grids to distinguish pollution levels

Severely polluted areas

Lightly polluted soil

How To Deal With The Contamination 1.Distinguish Contaminated Soil With Orginal Soil

Contaminated soil

Polluted water

Contaminated soil

Residues from explosions can lead to contamination of the upper layers of soil, which are divided into contaminated soil and original contaminated soil.

2.Remove Contaminated Soil

2.

Divide the site into 5m*5m grids

The shock wave caused by the explosion spread outward in a circular shape

3.

4.

The topography of the shock wave generated by the explosion and the 5m*5m grid form a fan, which explains why the subsequent excavation and filling of the soil block is in the shape of a fan.

Remove contaminated soil and reduce the footprint of contaminated soil.

5.

6.

Remove contaminated soil over lightly polluted soil, which achieves a cut-and-fill balance for earthworks.

Existing terrain was created after earth balancing.

Master Plan

1 Entrance Plaza 2 Grain Silos 3 Ecological Wetland

This city park was built on the site of the Beirut Port explosion.

To combat land contamination, the land was excavated and filled in to create an undulating topography, on top of which a memorial topography was made, and then many aquatic and terrestrial vegetation with purifying properties were planted, and the grain solis that were about to collapse were preserved to create a memorial landscape.

I hope that this park will be a memorial eco-park in remembrance of the explosion.

02 TO THE RIVER Heihui River Channel Reconstruction

CONCEPT : The Heilu River flows through Shaxi and is the mother river of Shaxi residents.

However, high city walls, non-water-friendly revetment design, and the discharge of agricultural and domestic sewage have kept people away from the river.

The project aims to solve this problem through water purification and revetment design.

Water flowing through a suddenly widening channel or structures like zig-zag sills and deflecting groynes changes the direction of flow and increases the river's dynamics.

Scour holes form and materials in the river are shifted and deposited,increasing habitat diversity. Low weirs were converted to river bottom ramps, and rockbaffles and groynes further increase flow variance.

03 TWINKLING STARS From quarry to observatory

CONCEPT : A city in Fujian is affected by light pollution and the stars cannot be seen. However, there is a quarry in the city which is far away from light pollution and has been abandoned for a long time. The project aims to transform this abandoned quarry into a unique star observatory through topographical design.

Background Of The Quarry

How Natural Stone Is Quarried

Today’s quarries are generally classified as a type of mine used for extracting dimension stone (blocks of stone) for residential and commercial building purposes. Quarries can be found in almost every corner of the earth.Limestone, gypsum, granite, marble, sandstone and slate are just a few of the many quarried materials. This quarry produces mainly granite, and the blocks cut here are shipped all over the world.

1. Blasting 50m

A The stone blocks are separated from the quarry wall by precision controlled rock blasting.

2. Excavation 100m

The excavator digs out the large stones, and then the stones of different sizes are cut, ground, and polished in the next step.

3. Cross-Cut Site How This Quarry Is Formed

318m

When the stone is cut against the vein, it is called a Cross-Cut, creating a more uniform look for the stone.

As global warming causes sea temperatures to rise, coral bleaching becomes more severe.

Australia's Great Barrier Reef, the world's largest and longest coral reef complex, is also in danger.

Already marine heatwaves have triggered four mass coral bleaching events on the Great Barrier Reef in just seven years, reducing shallow water coral reefs by as much as 50%.

This is an S-shaped river called Heihui river, located in the west of the entire Shaxi Ancient Town. Although the river bank is still under construction, it still attracts many tourists today.

Research Information

Ortho Projection Plan

Contour Line

Dem

Heihui River originates from Baihanchang, Jiuhe Township, Lijiang County, and its main stream is 341.8 kilometers long.

Among them, the length of the river in Lijiang County is 23.8 kilometers, and that in Jianchuan County is 61.3 kilometers.

Along Heihui River, there are dense population, warm climate, moderate rainfall, abundant sunshine, fertile land and other superior natural conditions.Besides, the farms along the river have been the main production areas of grain and cash crops in Dali.

We have done some research on the shape of the revetment, the life of the residents along the river, and the water quality of the river with the help of UAV imaging technology.
