Detailed description of the invention

Below in conjunction with detailed description of the invention, the utility model is further described.Wherein, accompanying drawing only for exemplary illustration, expression be only schematic diagram, but not pictorial diagram, can not be interpreted as the restriction to this patent; In order to embodiment of the present utility model is described better, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; For a person skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable.

The corresponding same or analogous parts of same or analogous label in the accompanying drawing of the utility model embodiment, in description of the present utility model, it will be appreciated that, if have term " on ", D score, " left side ", orientation or the position relationship of the instruction such as " right side " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore the term of position relationship is described only for exemplary illustration in accompanying drawing, the restriction to this patent can not be interpreted as, for the ordinary skill in the art, the concrete meaning of above-mentioned term can be understood as the case may be.

Please refer to accompanying drawing 1-7, the stake of the utility model T-shaped comprises solid top ends 1, wing plate 2 and web 3, and wherein said solid top ends 1 is positioned at above described wing plate 2, and described wing plate 2 also comprises the groove 4, wing plate tongue 5 and the wing plate groove 6 that are positioned at lower end.Described solid top ends 1, wing plate 2 and web 3 are formed by longitudinal stress main reinforcement 7, transverse structure reinforcing bar 8 and fill concrete 9.

The tip designs of T-shaped stake is solid top ends 1, is clamping and hammering in order to ensure bearing machinery during construction.

As a kind of preferred embodiment, described longitudinal stress main reinforcement 7 is PC rod iron for prestressed concrete.Longitudinal stress main reinforcement 7, along the longitudinal direction of T-shaped stake, is the principal rod of T-shaped stake, therefore adopts PC rod iron for prestressed concrete, ensure that the anti-bending strength of pile body.

As a kind of preferred embodiment, described transverse structure reinforcing bar 8 is plain bar or hard drawn wire reinforcement.

As a kind of preferred embodiment, described fill concrete 9 is the high-strength concrete of more than C50.The high-strength concrete of more than C50 ensure that the intensity of pile body and the feasibility of construction.

As a kind of preferred embodiment, described wing plate groove 6 is located at the side of described groove 4, and described wing plate tongue 5 is located at wing plate opposite side.Groove 4 enters soil layer to be beneficial to T-shaped stake, and when entering construction soil layer, groove 4 can produce the extruding force of a horizontal direction, makes the stake of hot work in progress close toward the adjacent studs having inserted soil layer, and what ensure between stake and stake is tight.

As a kind of preferred embodiment, described in the Thickness Ratio of described web 3, the thickness of wing plate 2 is thin.

As a kind of preferred embodiment, described wing plate tongue 5 being also embedded with sealing adhesive tape, when enclosing waterwall for construction, better waterproof effect can being obtained.

As shown in Figure 8, the joggle between wing plate tongue 5 and wing plate groove 6 can make between adjacent T-shaped stake more tight, also provides the function of location when constructing simultaneously.

Fig. 9 uses the utility model T-shaped stake splicing diaphragm wall schematic top plan view, according to the needs of required splicing diaphragm wall length, can select the T-shaped stake of varying number.

The utility model T-shaped stake manufacture process is as follows:

1, die-filling and stretch-draw: punching block is cleaned out, coats release agent, PC rod iron is pressed distributed steel requirement through mould, lock fixed end, PC rod iron is stretching successively and stretching end is locked on stretch-draw dish, outwards promote stretch-draw dish by hydraulic jack, PC rod iron is stretched to prolongation value and the stretching force of regulation, fixes the position of stretch-draw dish afterwards, prevent retraction, fixed form can adopt fixed base or directly fixing on punching block;

2, reinforcing cage is installed: on request distributing bar customized cut-off, curve corresponding shape, then be welded into reinforcing cage, whole reinforcing cage put into punching block, fixes with the colligation of PC rod iron;

3, concreting: by the formula ready-mixed concrete set, by sub-material and material-feeding mechanism, concrete is evenly distributed in mould, the dither (available vibrational pedestal or wall-hanging vibrator, shock club etc.) of short arc is carried out while cloth, make concrete even closely knit shaping, upper surface receives light again when concrete starts initial set;

4, maintenance is shaping: after concreting, normality is quiet stops 60 ~ 90 minutes, then entirety carries out stream curing, and adopt atmospheric steam curing to the concrete within C80, temperature controls at 80 ± 10 ° of C, until concrete strength reaches designing requirement.The stream curing of high pressure-temperature then also will be carried out to the concrete of more than C80;

5, form removal is checked and accepted: can unclamp stretch-draw dish after concrete reaches design strength, put a PC rod iron, open punching block, shaping stake is hung out, slice off and polish stake top and the outstanding PC rod iron of pile top, whole pile is checked, repairs, identified, puts in storage afterwards.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
