Description
Technical field
The present invention relates to a kind of raising sea wall mask foundation bearing capacity construction methods.
Background technique
Polder is firstly the need of construction sea wall, and soft base is the common technique problem encountered during sea wall is built, soft base
Self property determines that it is needed could be as the ground of engineering construction after consolidation process.At present mainly by after jackstone
It is in the milk again and completes the consolidation process of soft base, but on the one hand since sea wall length is big, need to throw during highway on soft ground
The mechanical equipment and earthwork entered is huge, causes project cost height；On the other hand, sea wall density requires high, and due to throwing
The effective rate of utilization for entering the marine cubic metre of earth and stone and slurries is lower, it is thus possible to and there are spillages, and the density that this will lead to sea wall is poor,
It is poor so as to cause the stability of sea wall.
In many polder areas in China, cubic metre of earth and stone source is more nervous, the environmental requirement that China is continuously improved in addition, soil
A large amount of excavations of the cubic meter of stone do not meet fundamental state policy requirement yet.For a large amount of excavations for reducing the cubic metre of earth and stone, also have using steel sheet pile at present
Cofferdam carries out sea wall construction, although this method speed of application is very fast, to reduce cost, and to avoid becoming after steel sheet pile is rotten
The stability of strong influence sea wall at through-hole usually requires that recycling steel sheet pile, however steel sheet pile dismounting is very inconvenient.
Summary of the invention
Above-mentioned technical problem present in present invention aims to solve the prior art, a kind of raising sea wall mask ground are held
Power construction method is carried to carry out processing reinforcing in the case where not removing former sea wall to the exterior wall of former sea wall, apply using two-way stirring
Work mixing pile, then by construction fixation kit and installation connection component, mixing pile is fixedly connected into it is a piece of, cement mixing pile with
Stake side tidal land mud forms composite foundation together, to improve foundation bearing capacity, reduces settlement of foundation and lateral displacement amount.The construction
Operation is simple and feasible for engineering method, reduces construction cost, and easy for construction, construction efficiency is high, can not only reduce engineering construction cost, but also can contract
Casual labourer's journey construction period, improve the returns of investment of engineering.
In order to solve the above-mentioned technical problem, it adopts the following technical scheme that
A kind of raising sea wall mask foundation bearing capacity construction method, comprising the following steps:
(1) preparation of construction.
