A circle spray of molten steel tube end at the height is welded and fixed.
By using above-mentioned technical proposal, cranse is adjacent to hole wall, equivalent to the hole wall from enlarged footing to the soil body around it
Expanded metal lath and reinforced mesh are pushed, also, cranse connects the steel floral tube at all sustained heights, can lift the branch of retaining wall
Protect effect.
Preferably, one end that the hole wall of enlarged footing is firstly inserted on the steel floral tube is provided with tip.
By using above-mentioned technical proposal, sophisticated setting, be advantageous to the process that hammers of steel floral tube, especially in excavated by manual work
At the enlarged footing of hole stake, construction space is limited, and one end of steel floral tube is made into tip, can reduce the power of hammering steel floral tube, from
And save large-scale hammering equipment.
Preferably, the stop grouting plug of sealing orifice is provided with the mouth of pipe of the steel floral tube.
By using above-mentioned technical proposal, after high-pressure slip-casting, the solidification of cement mortar needs a period of time, this period domestic demand
Prevent cement mortar from flowing out, the mouth of pipe of steel floral tube is blocked by stop grouting plug, prevent the cement mortar of press-in from flowing out the spray of molten steel before solidification
Pipe.
In summary, the utility model has the advantages that：Steel floral tube is squeezed on the hole wall at enlarged footing, then
Cement mortar is injected into steel floral tube, treats that cement mortar is combined with surrounding soil and solidifies to form floral tube soil nailing, its hole to enlarged footing
The soil body of wall plays reliable supporting role；With reference to the soil-baffling structure to be formed that is welded and fixed of expanded metal lath and steel floral tube, substitute existing
Some whitewashing dado structures, construction is simple, earth-retaining are reliable；And the fixation of reinforced mesh and expanded metal lath, degree of playing expanded metal lath add
Pretend use.
