Detailed description of the invention
Be described in further detail below in conjunction with the joint design of the drawings and specific embodiments to the precast splice type tunnel that the utility model proposes.According to the following describes and claims, advantage of the present utility model and feature will be clearer.It should be noted that, accompanying drawing all adopts the form that simplifies very much and all uses non-ratio accurately, only in order to object that is convenient, aid illustration the utility model embodiment lucidly.For sake of convenience, hereinafter described " on ", D score is consistent with the upper and lower direction of accompanying drawing, but this can not become the restriction of technical solutions of the utility model.
The utility model provides a kind of joint design of precast assembly tunnel, for solving hoop power transmission and the waterproof problem of precast assembly underpass.
The joint design in precast splice type tunnel of the present utility model is described in detail below in conjunction with Fig. 1 to Fig. 5.
Embodiment one
As shown in Figures 1 to 5, the joint design in precast splice type tunnel, joint design is tenon structure, tunnel is spliced by joint design successively hoop by some precast segments, precast segment comprises prefabricated middle wall unit 1, prefabricated side wall unit 2, Precast Underpass top board structure and Precast Underpass base arrangement, joint design comprises joint 1 and joint 24, connected by joint 1 between adjacent prefabricated middle wall unit 1, connected by joint 24 between adjacent prefabricated side wall unit 2, the middle part of joint 24 is provided with waterstop member 5.In the construction of precast assembly tunnel, i.e. prefabricated middle wall unit 1 and the setting parallel to each other of prefabricated side wall unit 2, Precast Underpass top board structure and Precast Underpass base arrangement parallel to each other, Precast Underpass top board structure is arranged perpendicular to prefabricated middle wall unit 1 and prefabricated side wall unit 2 respectively, Precast Underpass top board structure, prefabricated middle wall unit 1, Precast Underpass base arrangement and prefabricated side wall unit 2 head and the tail are in turn connected to form rectangular frame structure, thus form described underpass.At the scene during assembling construction, between adjacent precast segment, all leave gap between namely adjacent prefabricated middle wall unit 1 or between adjacent prefabricated side wall unit 2, the size in this gap and the size of joint design match.This joint design is tenon structure.By arranging tenon structure as joint design, the shear resistance of adjacent precast segment interface can be strengthened, thus ensure the hoop power transmission requirement of precast assembly underpass.In addition, assembled when meeting the prefabricated side wall unit 2 in native face, waterstop member 5 is set at the middle part of its joint 24, can prevents the gap of underground water between adjacent precast segment from infiltrating genuine, thus solve the waterproof problem of contiguous prefabricated assembly interface in precast assembly underpass.
Specifically, when produce in factory precast segment and joint design, the making material of precast segment is identical with the making material of tenon structure, is made by steel concrete.Be respectively equipped with groove in the middle part of the two ends of joint 1, the middle part of the butt end of corresponding prefabricated middle wall unit 1 is provided with the protuberance corresponding with groove.The structure of joint 24 and the structure difference of joint 1 are: the middle part of joint 24 is provided with waterstop member 5.This is because the prefabricated side wall unit 2 connected by joint 24 is positioned at meets native side, and it requires higher to water proof anti-seepage.Certainly, consider cost and convenience for construction, water-stopping structure 5 can be steel limit waterstop.
Accordingly, joint 1 and prefabricated middle wall unit 1, joint 24 and prefabricated side wall unit 2 build respectively be integrated for subsequent use.
Continue with reference to figure 2 and Fig. 4, certainly, in order to make the stressed integrality at interface place between adjacent precast segment, give full play to the effect of effective transmitting force of joint design, the main muscle of structure stress 1 (end is containing reinforcing bar connector 8) and structure stress main muscle 27 interlaced arrangement of precast segment.
Please continue to refer to Fig. 1 to Fig. 5, describe the construction method of the genuine joint design of precast splice type of the present embodiment in detail.The construction method of precast splice type joint design, comprises the following steps:
S001: according to job specfication, assembledly in genuine foundation ditch completes precast segment planning to build;
S002: be fixedly installed joint 1 in the butt end of adjacent prefabricated middle wall unit 1 respectively, is fixedly installed joint 24 in the butt end of adjacent prefabricated side wall unit 2, and in the middle part of joint 24 is arranged buried steel limit waterstop 5;
S003: build expansive concrete 9 in the gap between adjacent precast segment, expansive concrete 9 wraps joint design, makes adjacent precast segment form integrative-structure.
Specifically, the joint design interface that can prevent underground water between adjacent precast segment by buried steel limit waterstop 5 in arranging in the joint 24 of prefabricated side wall unit 2 of meeting native face infiltrates in tunnel.Expansive concrete 9 is built on the joint design surface of the precast segment spliced, expansive concrete 9 is made to wrap joint design, fill up the gap between adjacent precast segment, ensure that combining closely between joint design and precast segment, adjacent precast segment is made to form integrative-structure, thus avoid the space that joint design shrinks formation, thus define complete stressed and water-proof system.
Specifically, the main muscle of structure stress 1 of the precast segment in step one and structure stress main muscle 27 interlaced arrangement.The i.e. main muscle one, two (6,7) of the structure stress of prefabricated middle wall unit 1 and prefabricated side wall unit 2 all interlaced arrangement, thus ensure that the effective force effect of joint design.Certainly, stagger the length requirement that mechanical connecting joint that length need meet code requirement staggers mutually in the termination of the main muscle of structure stress 1 and the main muscle 27 of structure stress.
In sum, in the joint design in the precast splice type tunnel that the utility model provides, by arranging tenon structure as joint design, the shear resistance of adjacent precast segment interface can be strengthened, thus ensure the hoop power transmission requirement of precast assembly underpass.In addition, assembled when meeting the prefabricated side wall unit in native face, waterstop member is set at the middle part of its joint two, can prevents the gap of underground water between adjacent precast segment from infiltrating genuine, thus solve the waterproof problem of contiguous prefabricated assembly interface in precast assembly underpass.And, expansive concrete is built on the joint design surface of the precast segment spliced, expansive concrete is made to wrap joint design, fill up the gap between adjacent precast segment, ensure that combining closely between joint design and precast segment, make adjacent precast segment form integrative-structure, thus avoid the space that joint design shrinks formation, thus define complete stressed and water-proof system.
Foregoing description is only the description to the utility model preferred embodiment; any restriction not to the utility model scope; any change that the those of ordinary skill in the utility model field does according to above-mentioned disclosure, modification, all belong to the protection domain of claims.
