Description
Technical field
The present invention relates to technical field of construction, specifically a kind of ground crack resistence processing method.
Background technology
In recent years, with the continuous development and the mushroom development of urban construction of China's economy, especially some coastal cities
Land Demand constantly expands, existing land resources can not meet city continue develop demand, sea reclamation into
For the land development form that China's coastal region is main.At present, the construction technology for adopting in Scale Sea Reclamation Project is with waterpower hydraulic reclamation
Based on method.Waterpower hydraulic reclamation method refers to using machineries such as dredger and slush pumps, the mud in river course or surrounding waters is passed through
Special construction pipeline has the land of use value to desired target location through natural sediment.Medium coarse sand is one
Goodr water conservancy hydraulic reclamation material is planted, has had corresponding result of study to show to carry out epeirogenetic using medium coarse sand, can be obtained
Preferable achievement.Because the market price of sand is higher, and thing source is rare, and the use of medium coarse sand is gradually decreased in engineering.Will
Mud is not only able to river training, port and pier as the material of water conservancy hydraulic reclamation in river course or surrounding waters, can also protect
Environment, reduction cost of transportation, shortening foundation stabilization duration, are a kind of good methods achieved many things at one stroke.Therefore, in Practical Project generally
From the mud from coastal waters seabed or river course as waterpower hydraulic reclamation material.Because hydraulic reclamation soil's water content is very high, hole
It is also very higher than very big, decrement, intensity and permeability it is very low, and the hydraulic reclamation time is shorter, not yet consolidates 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 into
Rock process, therefore barged-in fill area building settlement is larger and the sedimentation deadline is very long, shows so as to form large-area land subsidence
As, when local settle uneven when can with ground cracking affect using with it is attractive in appearance.
For sea-filling region major structure of construction, typically using pile foundation, by the load of agent structure by stake it is incoming under
The supporting course of the preferable soil property in portion, it is ensured that the sedimentation of agent structure meets the requirement of specification.It is usually cost-effective at present, one layer of ground
Face typically directly adopts after building coats way, i.e. rammed earth and directly does 100mm concrete toppings.The method because of surface layer below
The soil body is not also consolidated, and after house use for many years, ground floor understands Continuous Settlement and settling amount is very big, and in post periphery cushion cap position
Put place's sedimentation less, cause to be ftractureed along cushion cap side on post periphery cushion cap junction ground, land subsidence beyond post periphery cushion cap, because
This normal treatment process has had a strong impact on the use of building and attractive in appearance.At present the method for solution ground floor cracking is mainly changed and filled 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 the problem that problem, but relatively costly.How low cost solves barged-in fill area one
The problem of layer ground cracking, is building field problem demanding prompt solution.
The content of the invention
It is an object of the invention to provide a kind of ground crack resistence processing method, to solve above-mentioned background technology in propose
