Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and with detailed description of the invention, the utility model to be further described, but the restriction not to its protection domain.
As shown in Fig. 1-Fig. 7, a kind of I-shaped steel joint formula diaphragm wall streams treating apparatus, comprise reinforcing cage 1, described reinforcing cage 1 both sides are provided with i shaped steel 2, i shaped steel 2 web outside two ends and wing plate intersection are provided with segment type slip casting steel pipe 4, and slip casting steel pipe 4 is arranged in each joint i iron web towards in the region of the second stage of groove section.Be provided with slip casting core pipe 5 in segment type slip casting steel pipe 4, slip casting core pipe 5 is connected with pneumatic mortar machine 9 by joint 14; Described segment type slip casting steel pipe 4 is evenly equipped with plum blossom hole 6, each plum blossom hole 6 is provided with unidirectional grouting stop-valve 8; Uniform gunniting hole within the scope of 3 meters bottom described slip casting core pipe 5.
The spacing of adjacent plum blossom hole 6 is 0.5-1 rice, and the eyelet level of plum blossom hole 6 is towards parallel with the wing plate of i shaped steel 2 and the medial surface of web surface respectively.
Segment type slip casting steel pipe 4 bottom is sealed, and top grouting port and the stage casing of segment type slip casting steel pipe 4 arrange stop grouting plug 7.
Pneumatic mortar machine 9 is also connected with mixer 10, pneumatic mortar machine 9 is provided with pressure meter 11.
Slip casting diameter of steel tube 48mm, bottom is sealed, and middle insertion diameter 32mm slip casting core pipe, the top grouting port of Grouting Pipe and stage casing arrange stop grouting plug 7, and bottom slip casting core pipe, 3m scope evenly bores gunniting hole, and pneumatic mortar machine is connected with slip casting core pipe.
The utility model is achieved in that
After the grooving of diaphragm wall first phase groove section is complete, inside I-shaped steel joint two ends, slip casting steel pipe is welded and fixed respectively by with pre-processed reinforcing cage, and put into ground-connecting-wall groove section with reinforcing cage, and mudjack is connected with slip casting core pipe, all preparations of concreting are completed according to program.
Start to build first phase groove section concrete, concreting is complete reach the initial setting time after start to note the water of certain pressure in segment type slip casting steel pipe, hydraulic pressure control in 0.2-1 MPa, to reach the concrete that dilution part flow-disturbing is come.Water flooding regime takes the mode of merogenesis water filling, sees Fig. 7 a, by core Guan Xiancong segment type slip casting steel pipe next joint water filling 5-15 minute, can stop when hydraulic pressure is reduced to lower limit; Then, mentioning core pipe to descending most penultimate water filling sections, making core pipe bottom block stop grouting plug mouth below, meeting bottom slip casting core pipe injected hole can only water filling in second water filling sections, see Fig. 7 b, water flooding regime is the same, and records water injection pressure and time etc.; By that analogy, see Fig. 7 d, merogenesis water filling from bottom to up completes the cement paste and concrete that first stage water filling cleaning flow-disturbing comes.
When completing the ground-connecting-wall concrete of first phase groove section, and after completing the grooving work of second phase groove section, now start to start mudjack to be rinsed by the remaining sand hill water under high pressure in the second stage of groove section I-shaped steel joint by grouting device, hydraulic pressure control is between 0.5-2 MPa.In the process, core Guan Xiancong carries out high pressure water injection in lower end, and to reach the remaining sand hill rinsed well in i shaped steel lower end, time controling was at 5 minutes to about 15 minutes.Then the bottom of core pipe is upwards twitched to middle part or upper segment, carry out high pressure water injection again 5 minutes to 15 minutes, its pressure size and time length can be carried out targetedly according to recording of first stage water filling cleaning, reach cleaning quality requirement to complete washing away of second stage in I-shaped steel joint from bottom to up.
After the second stage of groove section concrete has been built and concrete reaches design strength, start mudjack and the cement paste be stirred is carried out filling slip casting, grouting pressure controls in 0.3-1.5 MPa, to reach the gap of tamping between the second stage of groove section concrete and I-shaped steel joint.
