Description
Technical field
The present invention relates to a kind of raising sea wall mask foundation bearing capacity construction method.
Background technology
Polder is firstly the need of building sea wall, and soft base common technique difficult problem of running into during to be sea wall build, and the self property of soft base determines that it needs could be as the ground of engineering construction after consolidation process.Currently mainly by the consolidation process of the soft base that has been in the milk again after jackstone, but on the one hand big due to sea wall length, therefore need the plant equipment of input and earthwork huge during highway on soft ground, cause construction costs high；On the other hand, sea wall density requires height, and relatively low owing to being thrown into the effective rate of utilization of the marine cubic metre of earth and stone and serosity, it is thus possible to there is spillage, and this can cause the density of sea wall poor, thus causes the poor stability of sea wall.
In China's many polders area, cubic metre of earth and stone source is more nervous, and the environmental requirement that China improves constantly in addition, a large amount of excavations of the cubic metre of earth and stone do not meet fundamental state policy requirement yet.For reducing a large amount of excavations of the cubic metre of earth and stone, employing steel sheet-pile cofferdam is currently also had to carry out sea wall construction, although this method speed of application is very fast, but for reducing cost, and for avoiding steel sheet pile to become through hole and the stability of strong influence sea wall after rotting, usually require that recovery steel sheet pile, but steel sheet pile is removed very inconvenient.
Summary of the invention
Present invention aim at solving above-mentioned technical problem present in prior art, a kind of raising sea wall mask foundation bearing capacity construction method, in the case of not removing former sea wall, carry out processing reinforcing to the exterior wall of former sea wall, use two-way stirring construction mixing pile, then connect assembly by construction fixation kit and installation, mixing pile is fixedly connected into a piece of, cement mixing pile forms composite foundation together with the tidal land mud of stake limit, thus improves foundation bearing capacity, reduces settlement of foundation and lateral displacement amount.Operation is simple and feasible for this construction, reduces construction cost, easy construction, and efficiency of construction is high, both can reduce engineering construction cost, and can shorten again the engineering construction cycle, improves the returns of investment of engineering.
