Abstract
A compound cement-earth pile with hard core is made up by surrounding the prefabricated pile or tubular pile as hard core with the cement-earth mixture added with fly ash, early-strengthening agent, water reducing agent or sand aggregate. Its construction method includes mixing the cement-earth mixture with stirrer, constructing pile base of cement-earth mixture, and driving down pile as hard core with pile driver. It features high construction speed and is suitable for soft ground.
Description
The present invention relates to the bearing pile that a kind of building foundation is used, relate in particular to a kind of hard-core cement-earth compound pile and constructional method thereof that is applied to soft clay area.
At present, the area, Shanghai begins to promote and has the hard-core cement-earth compound pile that is suitable for soft clay area, patent No. ZL972429115, cement-earth length of time of finding this compound pile in force is long partially, early strength is lower, can influence follow-up engineering construction, this compound pile preparation of construction is single column compound pile machine (Fig. 1) or two column compound pile machines (Fig. 2) because of whipping device and pile sinking equipment all are fixed on same the stake machine, can't construct simultaneously, has reduced work efficiency.
The object of the present invention is to provide and a kind ofly have obvious raising compound pile pile strength, utilize the three wastes, improve the hard-core cement-earth compound pile and the constructional method thereof of work efficiency.
In order to achieve the above object, the cement-earth that hard-core cement-earth compound pile of the present invention is made hard core and this hard core of outsourcing by premculded pile or pile tube is formed, it is characterized in that mixing in the cement-earth toughener, described toughener is flyash or hardening accelerator or water reducer or sandy aggregate, is a kind ofly made toughener to four kinds of combinations and infiltrates in cement and the water and stir pulping by above-mentioned, and high pressure sprays into soil layer and original soil stirs into the pulpous state cement soil body, again hard core is sunk to cement-earth central authorities, treat that cement-earth ties hard pile
Hard-core cement-earth compound pile constructional method of the present invention, construct in order by mixing pile machine and ram engine and to finish, it is characterized in that described mixing pile machine and ram engine can relatively move, construction simultaneously, mixing pile machine is preceding, carry out stirring concrete earth construction earlier, ram engine after, carry out piling construction finishing on the stake position of cement-earth construction.Described mixing pile machine and ram engine are for independent device or formation one and both relatively-movable devices are constructed respectively.Be convenient construction, mixing pile machine or ram engine are walked in same walking on pipe or the rail, and the pile sinking equipment of described ram engine is pile hammer or vibration hammer or weight or rope static pressure device.
The present invention compared with prior art has the advantage of utilizing the three wastes, raising pile strength, improving work efficiency.
The drawing of accompanying drawing is described as follows:
Fig. 1 is single column compound pile machine schematic perspective view.
Fig. 2 looks synoptic diagram (a) and front-view schematic diagram (b) for two column compound pile pusher sides.
Fig. 3 is embodiment of the invention hard-core cement-earth compound pile diagrammatic cross-section (a) and floor map (b).
Fig. 4 is embodiment of the invention mixing pile machine and ram engine construction horizontal distribution synoptic diagram, and 4,6 is column among the figure.
One embodiment of the present of invention are referring to Fig. 3, Fig. 4, earlier spray into the grout that is mixed with flyash and water reducer and stir into the cylindricality pulpous state cement soil body (2) at the soil layer mesohigh of stake position a and move mixing pile machine (3) along rail (7) to a stake b with original place soil by existing mixing pile machine (3), continue the stirring construction of the cement-earth of stake position b, move existing ram engine (5) to a of stake position along rail (7), with vibration hammer premculded pile (1) is sunk to cement-earth (2) central authorities by the electric welding of joint overlap joint, move ram engine (5) along rail (7) again and to the b of stake position, carry out piling construction, treat the cement-earth knot hard hard-core cement-earth compound pile of the present invention.
