Embodiment Construction

[0043] The caisson process is used on land, and the soil within the sinking range of the caisson must be removed. The removal method can be mechanical removal or other methods.

[0044] The invention provides a method for using high-pressure water to wash the soil under a box into mud, and then pumping the mud away, so that the caisson continuously sinks in place as the soil layer under the box drops.

[0045] With this method, you must first determine whether there are obstacles in the soil layer in the range, see Picture 10 The method of judgment is as follows: In addition to drilling to understand the condition of the soil layer, a probe point is made every 1.5 meters to form a well-shaped distribution. The probe can be used to insert the iron rod, manual hammer penetration, or other mechanical detection methods. If it is found that there are large boulders or other obstacles in the sinking area of ​​the caisson, the treatment methods are as follows: a. First carry out undergr...

Abstract

The present invention relates to a land caisson construction process and land caisson. Said contruction process includes the following steps: firstly, completely closing or partial closing bottom plate of caisson, then sinking. Said land caisson is characterized by that the lower portion of periphery of the caisson is equipped with edge feet, several high-pressure water guns are vertically mounted on the bottom portion of caisson body, said water guns are communicated by water pipe.

Description

Technical field [0001] The invention relates to a land caisson construction technology and a land caisson. Background technique [0002] The use of caisson foundations in hydraulic construction projects is a common construction technique, but there is no precedent for the use of caisson construction techniques when building deep foundations and deep underground structures on land. [0003] Caisson is the main foundation type for building deep foundations and deep underground structures. It is made on the ground or in a pit. The open reinforced concrete barrel is first made. After the barrel reaches a certain strength, the soil is dug and transported in layers in the shaft regularly. As the soil surface in the well gradually decreases, the sunk shaft It is a deep foundation or underground engineering construction technology that overcomes the friction between the body and the soil wall by its own weight, and continuously sinks and settles in place. However, the caisson technique i...
