4) steel pile casting is set: the separate type processed tightly is bound round casing and is enclosed within former coagulation earth pillar, then tight garter spring hoop is tightly bound round on casing in separate type, tightened by bolt, fix;
5) end is built: tightly bind round casing as permanent template using separate type, and at former concrete column end young concrete, overall maintenance is shaping.
As preferably: step 4) in, tight garter spring is according to spaced 3 roads such as the size of separate type tight hoop iron casing is even.
As preferably: step 5) in, answer symmetrical construction during casting concrete, note when vibrating guaranteeing not disturbance steel column and former coagulation earth pillar.
As preferably: step 2) in, described strengthening rib is between steel column web symmetrically arranged two.
The invention has the beneficial effects as follows:
1, the setting that separate type tightly binds round casing serves the effect of template, strengthens steel column and the strength of joint of former coagulation earth pillar as permanent part, and separate type casing is easy for installation simultaneously.
2, tight garter spring strengthens separate type and tightly binds round casing and the friction resistance of former coagulation earth pillar, further increases the bearing capacity of pillar.
3, strengthening rib to be arranged so that steel column is connected with junction steel plate more tight, also improve the resistance to capsizing of steel column.
4, the combination being arranged so that junction steel plate and the vertical muscle of former post of nut more closely, makes the connection of steel column and former coagulation earth pillar more firm.
5, former column end onsite concrete makes steel column embedded in coagulation earth pillar, substantially increases the concatenation ability of the two.
