Basement reverse construction method for pipe jacking construction

The basement reverse construction method for pipe jacking construction is related to the construction of deep foundation pit support for pipe jacking construction, compared with conventional support and basement construction methods. The construction with reverse construction has obvious advantages, mainly including:

1 Simultaneous construction on the ground and underground to shorten the total construction period of the project;

The support of the 2nd floor cover is large, the deformation of the foundation pit is less, and the settlement of adjacent buildings is less;

3 retaining structure retaining soil, retaining water and bearing three-in-one, which can save the cost of engineering piles under the underground outdoor wall and external wall;

4 The structure of the floor structure can be used to save the support of the supporting structure;

5 Simplify the construction process of the foundation pit, with obvious economic benefits

With the promotion and application of the reverse method technology, China has included the provisions of the reverse construction method in the content of the foundation pit engineering of the new National Standard of the People's Republic of China, Building Design Basic Design Code, and the industry standard issued by the Ministry of Metallurgical Industry. The provisions of the basement reverse construction method are also listed in the Technical Code for Building Foundation Pit Engineering. Although the content of the basement reverse law in the relevant specifications is small, it shows that this technology has received increasing attention.

In the past two decades, although the basement reverse method technology has been widely used and developed due to its high safety and time saving, it has complicated technical integration, difficult basement construction and cost-oriented construction. High shortcomings, at the same time, there is no domestic normative document on the guidance and operability of the basement reverse technique. It often lacks the purpose and direction in the technical application. The design method and technical application fail to form a standardization, resulting in design and construction. Considering a lot of unnecessary waste, the various factors still hinder the further promotion of the basement reverse technology.

A salt lick is a deposit of mineral salts used by animals to supplement their nutrition, ensuring that they get enough minerals in their diets. A wide assortment of animals, primarily herbivores, use salt licks to get essential nutrients like calcium, magnesium, sodium, and zinc. When a saltlick appears, animals may travel to reach it, so the salt lick becomes a sort of rally point where lots of wildlife can be observed.

Farmers have historically provided salt licks for their cattle, horses, and other herbivores to encourage healthy Growth and development. Typically a salt lick in the form of a block is used in these circumstances, and the block may be mounted on a platform so that domesticated animals do not consume dirt from the ground along with the necessary salt. Salt blocks for farm animals can also be treated with medications, which may be convenient when someone needs to medicate shy animals, or a large group of animals.
