The total length of the ship lock is 6,442 meters. The upstream navigation channel is 2,113 meters, the downstream navigation channel is 2,708 meters, and the main section of the ship lock is 1,621 meters. The main section of the ship lock, the lock head and the lock chamber are divided into two lines, north and south, and are all excavated from the mountain rock. The main section of each line of the ship lock consists of 6 lock heads and 5 lock chambers, each lock chamber is 280 meters long and 34 meters wide, and the minimum water depth on the lock chamber is 5 meters. The Three Gorges Ship Lock can pass 10,000-ton fleets, with a designed annual one-way passing capacity of 50 million tons.</p><p class="ql-block">In addition to the lock head, lock chamber and navigation channel, the main buildings of the Three Gorges Ship Lock also include a water delivery system. The water delivery system consists of an upstream water inlet culvert, a main water delivery corridor, a diversion port and a lock chamber water delivery corridor, an auxiliary water discharge corridor, and a downstream water discharge culvert. The work of the ship lock is to raise the water level of the lock chamber by filling water through the water delivery system, or to release water to lower the water level of the lock chamber, so that the water level of the lock chamber is flush with the water level outside the lock chamber, and then open the gate to allow ships to pass through the dam step by step. It takes two and a half hours for a ship to pass through the ship lock.</p><p class="ql-block">The total head and number of levels of the Three Gorges ship lock are the highest in the world. Since the normal water storage level of the Three Gorges Dam is 175 meters above sea level, and the lowest water level under the dam is 62 meters above sea level, the vertical drop is 113 meters. In order to break up the water head, the Three Gorges permanent ship lock adopts a 5-level method to reduce the 113-meter water level drop step by step, so that ships can pass through the dam step by step like climbing stairs.</p><p class="ql-block">The Three Gorges ship lock broke ground on April 17, 1994, and the construction of the ship lock took 9 years. The ship lock miter gate is truly the "No. 1 Gate in the World", with a single door width of 20.2 meters, height of 38.5 meters, and thickness of 3 meters. The area of ??the gate is as large as two basketball courts and weighs more than 850 tons. The Three Gorges ship lock is the most technically complex ship lock in the world. Its single-stage lock chamber has a maximum working head of 45.2 meters and a maximum navigable flow rate of 56,700 cubic meters per second.</p> <p class="ql-block">中國三峽</p><p class="ql-block">三峽船閘之最</p><p class="ql-block">世界上最大的船閘</p><p class="ql-block">建造難度世界第一。為建船閘,建設(shè)者們削平了18座山頭,硬是在壩區(qū)左岸山崗中劈出一條道來,這在世界水利建設(shè)中是一道難題。</p><p class="ql-block">天下第一門</p><p class="ql-block">永久船閘共有24扇人字閘門。三分之二的人字門高36.75米,寬20.2米,厚3米,重達(dá)850噸,面積接近兩個籃球場,其外形與重量均為世界之最,號稱“天下第 一門”</p><p class="ql-block">基礎(chǔ)開挖最深</p><p class="ql-block">三峽船閘的開挖邊坡最大高度達(dá)170米,是世界船閘開挖邊坡高度之最。</p><p class="ql-block">世界船閘襯砌式結(jié)構(gòu)高度之最</p><p class="ql-block">三峽船閘為與巖體共同工作的薄襯砌結(jié)構(gòu),結(jié)構(gòu)最大高度達(dá)70米,是世界船閘村砌式結(jié)構(gòu)高度之最。這樣一個龐然大物,完全是中國人自己制造的,而且制造水 平相當(dāng)高,不僅開關(guān)自如,還滴水不漏。</p><p class="ql-block">世界級技術(shù)難題</p><p class="ql-block">三峽五級船閘是世界上規(guī)模最大,水頭和技術(shù)難度最高,它要解決的問題都遠(yuǎn)遠(yuǎn)超過了一般的船閘。三峽船閘的建成,表明中國在這方面的技術(shù)已達(dá)到世界領(lǐng)先 水平。三峽船閘水頭很高,要采用多級船間解決水力學(xué)問題和更好地適應(yīng)三峽地形的條件。五級船閘的總設(shè)計水頭為113米,分成了五級以后,上下級之間最大水頭 還有45.2米,這個數(shù)字仍大大超過世界上最大一級船閘34.5米的水頭,所以為解決船閘的水力學(xué)問題需要在輸水系統(tǒng)布置方面以及廊道的高程和體形方面、閥門的形 式等各個方面采取特殊的不同一般船閘的做法。另外,船閘在巖石山體里面開挖興建三峽的船閘基礎(chǔ)條件很好,為了充分利用巖石的優(yōu)良條件,節(jié)省工程量,結(jié)構(gòu)采 用了薄襯砌的閘室、閘首和輸水隧洞。在兩線船閘中間保留了巖體隔墩,要求混凝土結(jié)構(gòu)與巖石共同承受荷載,所以在設(shè)計和施工方面就要相應(yīng)地采取一系列技術(shù)措 施,以保證結(jié)構(gòu)和山體安全正常地工作的條件。由于船閘上下游水位落差達(dá)113米,修建船閘要在花崗巖山體中切出一道最大開挖深度為176米的高邊坡。如何保持 高邊坡巖體內(nèi)的穩(wěn)定和控制邊坡的變形,經(jīng)過多年潛心攻關(guān),長江委提出船閘高邊坡設(shè)計方案,較好地解決了高邊坡的穩(wěn)定和變形控制問題。船閘的閘門最大高度達(dá) 到38.5米,閘門結(jié)構(gòu)既要滿足受力的剛度要求,又要能夠適應(yīng)巖體少量變形時可靠止水。閘門的重量超過800噸,所以閘門的底部的潤滑要采取如今世界上比較新的 自潤滑技術(shù)。除此之外,三峽船閘運(yùn)行工況復(fù)雜,如何保證對船閘實(shí)施實(shí)施有效監(jiān)控,以及船閘的安全監(jiān)測、消防等問題均屬技術(shù)難題,設(shè)計人員均一一破解。</p><p class="ql-block">級數(shù)之最</p><p class="ql-block">葛洲壩船閘是一級船閘,三峽船閘是五級船閘,為目前全球級數(shù)最多的船閘。</p><p class="ql-block">水頭:葛洲壩船閘的最大水頭為27米,而三峽船閘的總水頭為113米,單級最大工作水頭45.2米,無論總水頭還是單級水頭都比葛洲壩船閘大,為目前世界船閘中</p><p class="ql-block">“水頭之最”。</p><p class="ql-block">閘門大小和重量</p><p class="ql-block">葛洲壩閘人字門最大高度為34.5米,重為600噸,而三峽船閘人字門最大高度38.5米,人字門最大單扇門重850噸,是當(dāng)今的“世界之最”。</p><p class="ql-block"><br></p> <p class="ql-block">China Three Gorges</p><p class="ql-block">The largest ship lock in the Three Gorges</p><p class="ql-block">The largest ship lock in the world</p><p class="ql-block">The most difficult to build in the world.

The maximum height of the structure is 70 meters, which is the highest village masonry structure height of the world's ship lock. Such a huge thing is completely made by the Chinese themselves, and the manufacturing level is quite high. It can not only open and close freely, but also is watertight.</p><p class="ql-block">World-class technical difficulties</p><p class="ql-block">The five-level ship lock of the Three Gorges is the largest in the world, with the highest water head and technical difficulty. The problems it has to solve are far more than those of ordinary ship locks. The completion of the Three Gorges ship lock shows that China's technology in this area has reached the world's leading level. The water head of the Three Gorges ship lock is very high, and it is necessary to use multi-level ship locks to solve hydraulic problems and better adapt to the conditions of the Three Gorges terrain. The total design water head of the five-level ship lock is 113 meters. After being divided into five levels, the maximum water head between the upper and lower levels is still 45.2 meters. This number is still much higher than the 34.5-meter head of the world's largest first-level ship lock. Therefore, in order to solve the hydraulic problems of the ship lock, it is necessary to adopt special practices different from those of ordinary ship locks in terms of water delivery system layout, corridor elevation and shape, valve form, etc. In addition, the ship lock was built in the rock mountain. The foundation conditions of the Three Gorges ship lock are very good. In order to make full use of the excellent conditions of the rock and save engineering work, the structure adopts a thin-lined lock chamber, lock head and water tunnel. The rock pier is retained between the two lines of the ship lock, requiring the concrete structure and the rock to bear the load together. Therefore, a series of technical measures must be taken in the design and construction to ensure the safe and normal working conditions of the structure and the mountain. Since the water level difference between the upstream and downstream of the ship lock is 113 meters, a high slope with a maximum excavation depth of 176 meters must be cut out in the granite mountain to build the ship lock. How to maintain the stability of the high slope rock body and control the deformation of the slope? After years of dedicated research, the Yangtze River Commission proposed a high slope design plan for the ship lock, which better solved the problem of stability and deformation control of the high slope. The maximum height of the ship lock gate reaches 38.5 meters. The gate structure must not only meet the stiffness requirements of the force, but also be able to reliably stop water when the rock mass deforms slightly. The weight of the gate exceeds 800 tons, so the lubrication of the bottom of the gate must adopt the world's newest self-lubricating technology. In addition, the Three Gorges ship lock has complex operating conditions. How to ensure effective monitoring of the ship lock, as well as the safety monitoring and fire protection of the ship lock are all technical problems, and the designers have solved them one by one.</p><p class="ql-block">The most levels</p><p class="ql-block">The Gezhouba ship lock is a first-level ship lock, and the Three Gorges ship lock is a fifth-level ship lock, which is currently the world's most level ship lock.</p><p class="ql-block">Water head: The maximum water head of the Gezhouba ship lock is 27 meters, while the total water head of the Three Gorges ship lock is 113 meters, and the maximum working water head of a single stage is 45.2 meters.
