Pull-type soil shifter smoothing technique for soft foundation field and pull-type soil shifter

Abstract

The invention relates to a 'pull type bulldozer' smoothing technique in soft foundation fields and a pull type bulldozer thereof; the technique utilizes a twin hull floating pontoon to coordinate with a small-sized hoisting hook, the small-sized hoisting hook coordinates with a mouldboard to fabricate the pull type bulldozer, and the pull type bulldozer is used for the construction of bulldozing and smoothing fields. The specific construction technology comprises the following steps: both the conveying rope front and back ends of a hoisting machine on the twin hull floating pontoon are fixed on cofferdams or embankments on the front and back ends of an area that needs construction, each anchor is managed by a person, and then the starting point and direction of the pull type bulldozer aredefined; after defining the starting point and direction of the pull type bulldozer for bulldozing construction, the lifting drum is turned by staff who are responsible for walk on the twin hull floating pontoon, the conveying rope is turned by the lifting drum to control the walk of the twin hull floating pontoon, and the mouldboard is sunk by the staff who are responsible for hoisting on the floating pontoon to push the soft soil from a high place to a low place. The method and the pull type bulldozer enable work staff and machines to smooth fields on newly hydraulically filled fields.

Description

(1) Technical field [0001] The invention relates to a soft ground ground leveling treatment method and a special traction bulldozer thereof. It is suitable for the leveling treatment of newly dredged silt weak foundation. It belongs to the technical field of foundation treatment. (2) Background technology [0002] At present, due to the country's protection of farmland, the development of coastal areas generally adopts the method of reclamation from the sea, and adopts the method of reclamation to achieve the required elevation of construction. Due to the complex land conditions of the new dredging and filling silt, and the inaccessibility of people and mechanical equipment, in order to make the elevation of the site basically the same, in the process of dredging and filling, the method of manually moving the dredging and filling mouth (commonly known as: mud blowing mouth) To achieve the required elevation of the dredged silt. In fact, due to the weak geology of the fil...

Problems solved by technology

This is because it is far away from the mud blowing port, even if a large amount of muddy water arrives, due to the high water content, after the surface water is drained, the required elevation cannot be reached at all, resulting in high mud blowing ports and low remote areas. The hilly terrain has caused great difficulties in the treatment of weak foundations

Not only that, due to the inconsistency of the site elevation and the nature of the foundation soil, the settlement will be inconsistent and the reinforcement depth will be inconsistent, which will bring great difficulties to the design

It leaves a great hidden danger for the treatment of weak foundation
