Description
Technical field
The present invention relates to technical field of construction, specifically a kind of ground crack resistence processing method.
Background technique
In recent years, with the mushroom development of continuous development and the urban construction of China's economy, especially some coastal cities
Land Demand constantly expands, existing land resources be no longer satisfied city continue development demand, sea reclamation at
For the main land development form of China's coastal region.Currently, the construction technology used in Scale Sea Reclamation Project is with waterpower hydraulic reclamation
Based on method.Waterpower hydraulic reclamation method refers to mechanical using dredger and slush pump etc., and the mud in river or surrounding waters is passed through
Special construction pipeline has the land of use value by natural sediment to desired target location.Medium coarse sand is one
The prettyr good water conservancy hydraulic reclamation material of kind has had corresponding result of study to show to carry out epeirogenetic using medium coarse sand, can obtain
Preferable achievement.Since the market price of sand is relatively high, and material resource is rare, and the use of medium coarse sand is gradually decreased in engineering.It will
Material of the mud as water conservancy hydraulic reclamation in river or surrounding waters, is not only able to river training, port and pier, can also protect
Environment reduces transportation cost, shortens the foundation stabilization duration, is a kind of good method achieved many things at one stroke.Therefore, in Practical Project usually
Select material of the mud as waterpower hydraulic reclamation from coastal waters seabed or river.Since hydraulic reclamation soil's water content is very high, hole
Than very big, decrement is also very high, intensity and permeability are very low, and the hydraulic reclamation time is shorter, not yet consolidate under Gravitative Loads, also
Be say natural surface subsidence be earth's surface is loose or half loose barged-in fill under gravity, by loosely to it is fine and closely woven at
Rock process, therefore barged-in fill area building settlement is larger and the sedimentation deadline is very long, so that the land subsidence for forming large area is existing
As when locally sedimentation is uneven use and beauty can be influenced with ground cracking.
For sea-filling region major structure of construction, pile foundation is generally used, under the load of main structure is passed to by stake
The supporting course of the preferable soil property in portion, it is ensured that the sedimentation of main structure meets the requirement of specification.It is at present usually save the cost, one layer of ground
Face generally directlys adopt building coats way, i.e., 100mm concrete topping is directly done after rammed earth.This method because of surface layer below
The soil body does not consolidate also, and after house is using many years, ground floor understands Continuous Settlement and settling amount is very big, and in column periphery cushion cap position
It is smaller to set place's sedimentation, causes to crack on column periphery cushion cap junction ground along cushion cap side, land subsidence other than the cushion cap of column periphery, because
This normal treatment process has seriously affected the use and beauty of building.The method for solving ground floor cracking at present, which is mainly changed, fills out
Sand-gravel-cushion Technioue, deal pile, cement mixing pile, drain bar add the method for processing foundation such as piling prepressing, or directly do one layer it is overhead existing
Pour reinforced concrete floor.
Although above-mentioned processing method can effectively solve problem, but higher cost.How low cost solves barged-in fill area one
The problem of layer ground cracking, be building field urgent problem to be solved.
Summary of the invention
It is mentioned above in the background art to solve the purpose of the present invention is to provide a kind of ground crack resistence processing method
Problem.
To achieve the above object, the invention provides the following technical scheme:
