Unexpectedly, two months later, the boring company was established! It’s musk, the most executive man in the world! (boring means boring as well as digging a hole, a pun.) just do it.
IV.
It is clear that it usually takes 3-6 months / mile to build a tunnel in the United States, and the cost is 1 billion US dollars / mile.
Although smaller diameter TBMs are automated, larger TBMs currently require multiple manual operators.
In reality, TBM is very slow.
This is inefficient.
Current tunnel operations usually include diesel locomotives.
In January 2018, the average cost per mile of subway projects in the United States, while the tunnel cost only $10 million (excluding the purchase cost of TBM), which is 99% lower than the original cost!!! How did boring companies achieve substantial cost reduction? 1、 All underground, the cost of land acquisition and demolition is saved.
Not only the speed lever drops, this demonstration tunnel also has many points that can be blown up, especially in terms of cost control.
Musk from heaven to earth has come to grab the job of the construction industry! Recently, when everyone was swiped by the news that the manned “dragon” spacecraft of Musk’s space company SpaceX took off smoothly, Musk’s boring hole digging company quietly won two more tunnel orders! According to foreign media reports, on June 3, Clark County Commissioner Tim segerblom tweeted a map of the proposed tunnel, which extends westward from Las Vegas Convention Center to Wynn and encore, two Casino hotels owned by Wynn Resorts.
The melon eaters thought it was just a small complaint.
And set up a brick company, specializing in the production and sale of bricks.
Improve TBM automation.
Text: 2990 words, expected reading time: 8 minutes source: WPR (invasion and deletion) reduces the tunnel cost by 99% in one breath! Musk is coming to China to dig a hole! This is not an ordinary tunnel, but an underground high-speed tunnel with a speed of 240km / h! If possible, it will also bring a complete underground transportation system.
The tunnel is only 12 feet in diameter and can accommodate a car.
By using an autonomous electric vehicle (AEV), the diameter can be reduced to less than 14 feet.
Boring company just completed two underground tunnels in Las Vegas Convention Center in May this year.
Continuous construction.
Reducing the diameter by half can reduce the tunnel cost by 3-4 times.
When building a tunnel, it may only take 10 minutes to drill a hole and 50 minutes to build a frame for support.
Musk, who was blocked in the street on December 17, 2016, sent three tweets and announced that he would set up a company to solve the traffic jam problem.
Even if the salary is low, they are willing to work with musk..
Needless to say, those engaged in the project know that if it is an aboveground expressway, the early cost of land acquisition and demolition is not a small expenditure.
Most of the employees employed by the company are interns.
On June 9, Wynn resort also officially announced that it would cooperate with boring company, and has submitted the land use application of the project.
And his low cost is the big killer of all Chinese construction enterprises! Some people describe the experience of iron man musk as follows: musk wanted a new payment method, so he set up a PayPal; Musk wanted to drive an electric car, so he founded Tesla; Musk wanted the space station to be cheaper, so he built his own SpaceX launch rocket; Musk wanted to speed up the traffic, so he “developed” the hyperloop that can “launch” people.
Boring company improves the existing construction efficiency by modifying the existing technology.
2、 The current standard for single lane tunnels is about 28 feet.
These have been replaced by electric locomotives.
The power output of the machine can be increased by three times (together with the appropriate upgrading of the cooling system).
The snail speed is 14 times that of soft soil TBM.
The boring company team will refit the bought second-hand TBM and improve its speed in a variety of ways, including increasing TBM power.
3、 Large equipment is purchased and improved, and the machinery cost is saved.
The first thing a boring company does is dig a hole! In February 2017, musk dug a “demo tunnel” in the parking lot of SpaceX; In August 2017, boring company was approved to dig a 2-mile-long pilot tunnel in Los Angeles; On November 18, 2018, the first demonstration tunnel in Los Angeles was unveiled.
The waste slag treatment fee saves the usual tunnel excavation, and a waste slag yard needs to be built to transport the waste soil.
Up to 150 mph (equivalent to 241km / h), what is the concept? You know, the speed of domestic subway is only 80 ~ 100km / h, which is about the same as our feeling of taking the bullet train! This tunnel can also realize remote control color change, allowing you to be in the rainbow tunnel.
Although all of them were completed by boring company with its own funds, it can be seen that with this model, other commercial tunnel orders will follow! The establishment of boring company originated from a traffic jam.
The price of these bricks is only 1 cent / piece, while the local brick price is much higher, and the market price is 4.9 cents / piece.
By automating large TBM, safety and efficiency can be improved.
The automatic handle can operate the game console and feel powered on.
The process is expensive, time-consuming, noisy and may be harmful to the environment.
Boring companies have developed technology to recycle the earth into useful bricks for building and paving bricks.
5、 The project is completed by interns and part-time employees, and the labor cost is reduced.
the soil slag is processed into bricks for the second time.
The car only needs to install guide wheels to move forward at high speed.
