Cement mixing pile composite foundation construction technology


7-layer brick structure, according to geological drilling data are reported at a 83m layer of silt sand, the shallow geological evaluation of the proposed site for the weak layer of high compression, the need for reinforcement I choose three kinds of companies were calculated on pile type: precast piles of 153.08 yuan / m. } Hand-dug pile of 108 yuan / m, while the cement mixing of only 66 yuan / m. Therefore decided to use cement deep mixing composite foundation cement mixing method fluttering work fast, good economic returns, the construction of safe,tory burch outlet, reliable, simple construction machinery. Cement mixing pile arrangement then grill, pile diameter 0.5m, pile length 8.5m, allowable bearing capacity of composite foundation requirements l60kPa, unconfined compressive strength of cement-soil up to 1.8MPa, the corresponding allowable bearing capacity of pile is 120kN, Cement blending amount of reinforced soil heavy l5, per cubic meter of cement mixed with cement mixing pile 280kg1 construction machinery (1) DSJ-I single-axis concrete mixer, shaft speed 60r/rain, speed lm / rain, motor power 22kW, maximum torque 9kN · m, mixing blade diameter 0.5m. (2) the amount of mortar mixing machine pit 200L (3) Ash slurry pump into the pressure of the normal 30 ~ 60N/cm. 2 4-Huan system pile process shotcrete, 4 mixing of the construction process. Construction sequence for the positioning of a clear tube into a pulp and a pulp a spray,mulberry outlet, drilling, mixing a spray, to enhance, mixing a spray, drilling, mixing an enhanced mixing. 3 construction parameters speed lm / minI speed 60r/minI cement ratio of cement with water a water-reducing agent-1. O-0.5, O. 002} cement dosage average of 15 (accounting for reinforced soil weight). Sustaining power for the benefit of the pile, the upper dosage of 17 cement 3m, 5.5m lower dosage 13I cement mortar inside each feeding cement 2O0kg-F water 1O0kg-F superplasticizer o4kg water or cement 150kg + 75kg + superplasticizer 0. 3kg. 4 Quality Control (1) The pile must be accurate, pre-construction buildings should be re-edge axis, benchmarks, and site elevation. (2) Pile up line should be in strict accordance with design requirements,######## oakley sunglasses, deviation of not more than 1.0cm. (3) removal of the surface barrier, if the depth of 1rn ~ 1.5m the following obstacles exist, and designers can discuss appropriate treatment. (4) using ordinary portland cement 425 should have a single factory warranty. (J) strictly control the water-cement ratio (0.5:1.0), water should be accurate (6) must be fully uniform mixing cement, mixing after each cast section is not less than 3min,ed hardy canada, mixing must be continuous to ensure that for plasma does not interrupt (7) equipment in place, to be flat solid, mixing piles shall not exceed 1 vertical deviation. Pile of Pile of error of not more than 2cm. (B1 decadent mouth spray to be emitted from the slurry and a certain pressure, before it began drilling operations mixing shotcrete, shotcrete to be to the design depth of drilling, and make records. (9) pressure changes observed at any time, In case of abnormal (high or low pressure gauge) should identify the reasons for the record, if properly handled and sprayed interrupt occurs, you must continue to spray after the re-start from the ground work, not to stay a certain length of the lap after starting from the middle of the work (10) should always measure the diameter of mixing blades, if less than the specified diameter 5ram, should be replaced immediately. 5 technical and economic effect (1) cement mixing pile composite foundation process simple, safe, can reduce the cost, speed, ensure that the use quality, have been completed in respect of buildings is not unusual (2) the normal state can be prepared for each class of pile 2o reported. down such as: construction area of ​​2352 ~ n2,Beats By Dre Headphones, 7-story building, 300 reported that the pile 15 calendar days to complete. (3) the settlement value: take design specifications, building foundations, Shen btah is the ultimate long-range pile composite soil deformation and pile the following the force of compression deformation of the soil and composite soil deformation desirable 10 ~ 30mm, the design basis for settlement set aside 10cm. Field static load tests: plate 1m × 2.0m, loading from 640kN to 13.01mm when the final settlement of the measured settlement building cap; maximum settlement amount of 1.4cm , the minimum settlement amount of O.7cm, the maximum differential settlement of 0.? cm
