Interval is set to several vertical Grouting Pipes outside steel reinforcement cage ontology both sides, and each vertical Grouting Pipe is respective
It is connected to a lateral Grouting Pipe.
Based on the above technical solution, the grouting valve is check-valves.
Based on the above technical solution, the lateral Grouting Pipe and vertical Grouting Pipe pass through welding and the reinforcing bar
Cage ontology is connected.
Based on the above technical solution, the adjacent vertical slip casting tube spacing is 2m.
Based on the above technical solution, the minimum range of lateral Grouting Pipe to the steel reinforcement cage body bottom portion is equal
For 8m.
Based on the above technical solution, the adjacent grout outlet spacing being arranged in each lateral Grouting Pipe is
2m。
Based on the above technical solution, the adjacent lateral slip casting tube spacing is 8m.
Compared with prior art, the utility model has the advantage of：
(1) steel reinforcement cage of a kind of diaphram wall with grouting device in the utility model, by the way that connection is arranged
Vertical Grouting Pipe and lateral Grouting Pipe can be completed to diaphram wall when pouring, by being connected to lateral Grouting Pipe and
Grout outlet equipped with grouting valve can carry out grouting operation, the slip casting to diaphram wall both sides be completed, to keep underground continuous
The frictional resistance of wall and surrounding soil enhances.

Specific implementation mode
The embodiments of the present invention are described in further detail below in conjunction with attached drawing.
Shown in Fig. 1 to Fig. 3, the utility model embodiment provides a kind of steel of the diaphram wall with grouting device
Muscle cage includes several transverse directions for pouring the steel reinforcement cage ontology 1 of diaphram wall, interval outside 1 both sides of steel reinforcement cage ontology
Grouting Pipe 2 and interval are set to several vertical Grouting Pipes 3 outside 1 both sides of steel reinforcement cage ontology, and lateral Grouting Pipe 2 is arranged at intervals with several
Grout outlet 21, and a grouting valve 22 is equipped at grout outlet 21, it is preferred that grouting valve 22 is check-valves, and each vertical Grouting Pipe 3 is equal
A lateral Grouting Pipe 2 is each communicated with, by the way that the lateral Grouting Pipe 2 and vertical Grouting Pipe 3 of connection are arranged in diaphram wall both sides,
And grout outlet 21 and its corresponding grouting valve 22 are set in lateral Grouting Pipe 2, can when pouring completion to diaphram wall,
By the both sides for the diaphram wall that vertical Grouting Pipe 3, lateral Grouting Pipe 2 and grouting valve 22 have poured slurries injection, wait for
After the grout cures of diaphram wall both sides, the structure of formation increases the frictional resistance of underground continuous wall body and surrounding soil,
The diaphram wall that anti-floating pile is arranged compared to existing measure of anti float and is only contacted with undisturbed soil, reduces project cost, shortens
Duration and reduce construction risk.
Wherein, further, it when the steel reinforcement cage is invested in groove and is ready for pouring, meets native side transverse direction Grouting Pipe 2 and arrives
Ground minimum range, excavation side transverse direction Grouting Pipe 2 to foundation pit bottom minimum range and lateral Grouting Pipe 2 arrive 1 bottom of steel reinforcement cage ontology
Minimum range be 8m, 21 spacing of adjacent grout outlet being arranged in each transverse direction Grouting Pipe 2 is 2m, adjacent transverse Grouting Pipe 2
Spacing is 8m；2m is divided between adjacent vertical Grouting Pipe 3, lateral Grouting Pipe 2 and vertical Grouting Pipe 3 pass through welding and steel reinforcement cage sheet
Body 1 is connected, and by welding lateral Grouting Pipe 2 and vertical Grouting Pipe 3 with steel reinforcement cage ontology 1, can improve 2 He of lateral Grouting Pipe
The bonding strength of vertical Grouting Pipe 3 and steel reinforcement cage ontology 1 avoids horizontal caused by effect during decline due to surrounding soil
It changes to the position of Grouting Pipe 2 and vertical Grouting Pipe 3, certain influence is generated to subsequent slip casting.
Shown in Fig. 1 to Fig. 3, completed to diaphragm wall and its float Structure slip casting by the steel reinforcement cage in the utility model
The step of be：
One, by lateral Grouting Pipe 2 and vertical Grouting Pipe 3 along the longitudinal banding fixed of steel reinforcement cage ontology 1 of diaphram wall or
Welding, underground continuous wall body both sides are respectively provided with lateral Grouting Pipe 2 and vertical Grouting Pipe 3.In the same of placing of reinforcement cage ontology 1
When, the lateral Grouting Pipe 2 being fixed on the outside of reinforcing bar and vertical Grouting Pipe 3 are put into togerther in groove；
Two, lateral Grouting Pipe 2, vertical Grouting Pipe 3 and note are determined to integrate according to the depth of periphery soil layer property and foundation pit
Starch the quantity of valve 22.For excavating side, generally can from bottom of foundation ditch 8m hereinafter, diaphram wall bottom 8m or more, every 8m
The lateral Grouting Pipe 2 of setting one, every lateral Grouting Pipe 2 are correspondingly connected with a vertical Grouting Pipe 3, and grouting valve 22, which is located at, laterally to be noted
It starches on pipe 2, a grouting valve 22 is arranged every 2m in every lateral Grouting Pipe 2；It, can be at the top of from diaphram wall for meeting native side
A lateral Grouting Pipe 2,2 connection type of lateral Grouting Pipe and note is arranged every 8m hereinafter, diaphram wall bottom 8m or more in 8m
It is identical as side is excavated to starch 22 set-up mode of valve；
Three, for there are ovum, gravel either medium coarse sand stratum by lateral Grouting Pipe 2 be arranged ovum, gravel or in it is thick
Layer of sand lower part；
Four, grouting valve 22 should use check-valves that can ensure that slurries will not pour into valve when pouring diaphram wall, note
Slurries will not flow back when slurry；
Five, after the completion of waiting for that diaphram wall pours, start to the slip casting of diaphragm wall both sides.It is suitable using slip casting from top to bottom
Sequence, in case lower slurry is altered with wall.First since topmost grouting valve 22, wait for that the slip casting soil body forms certain initial setting strength
Afterwards, it then opens lower part grouting valve and carries out slip casting.
