According to the rigid joint, a groove-shaped joint plate (5) is connected to the end of a groove-shaped-end steel reinforcement cage (3), joint baffle guide grooves (6) are connected to the outer sides of the two ends of the groove-shaped joint plate (5) and are made from notched steel pipes, a joint baffle (7) is inserted into the baffle guide grooves (6), and concrete is cast into the groove-shaped-end steel reinforcement cage (3), so as to form a first underground continuous wall (1); the boss end of a boss-shaped steel reinforcement cage (4) is matched with the groove-shaped joint plate (5) of the first underground continuous wall (1), and concrete is cast into the boss-shaped steel reinforcement cage (4), so as to form a second underground continuous wall (2); the joint baffle can be used repeatedly, and the construction is pollution-free to environment; the process is simpler compared with the traditional rigid joints, and the lateral rigidity and water sealing performance of the rigid joint can be improved more effectively compared with the those of the traditional tube lock construction processes.
Description
Technical field
The utility model relates to Geotechnical Engineering field, relates in particular to a kind of rigid joint for underground continuous wall.
Background technology
Diaphragm wall, as one of the most effective foundation pit supporting construction form, is widely used in a large amount of underground constructions.But due to construction of diaphragm wall technological process relative complex, longitudinally adjacent two groove segment units exist inevitable construction joint, and construction joint often becomes the weak part of the super deep water soil pressure of opposing.In construction and use procedure, joint all should meet stressed and requirement (guaranteeing impermeability and the globality of body of wall) antiseepage, and it is simple to make every effort to construction, and the grooving of next unit groove section is not caused to difficulty.
Rigid joint for underground continuous wall is due to bar splicing, makes that joint area lateral rigidity is large, infiltration path is longer, is not easy to occur the problems such as seepage water burst, because adapter plate has certain guidance quality, so that adjacent slot section is connected is comparatively straight, is difficult for jag, faulting of slab ends.The conventional rigid joint mode of construction has i iron rigid joint, cross steel plate joint, the rigid joint of male and female groove section etc.Due to rigid joint for underground continuous wall construction technology relative complex, joint area overlap joint is complex-shaped, causes that its brush wall difficulty is large, the time long, weak effect, and the duration is lengthened.
The utility model adopts the combination construction mode of a kind of fluted body adapter plate and joint baffle, and without snap close pipe and joint case, fluted body adapter plate place is without brush wall, and wall connecting is tightr, simultaneously the reduction of erection time.
Summary of the invention
Technical problem: the utility model object is to provide a kind of rigid joint for underground continuous wall, adopt the combination construction mode of a kind of fluted body adapter plate and joint baffle, form of structure simply without snap close pipe and joint case, fluted body adapter plate place without brush wall, wall connecting more closely, the quick construction reduction of erection time.More simpler than conventional rigid joint technique.
Technical scheme: a kind of rigid joint for underground continuous wall of the present utility model comprises the first diaphragm wall, the second diaphragm wall, fluted body termination reinforcing cage, boss shape reinforcing cage, fluted body adapter plate, joint baffle guide groove, joint baffle, Grouting Pipe;
Fluted body adapter plate is connected to the termination of fluted body termination reinforcing cage, jointing baffle plate guide groove outside fluted body adapter plate two ends, joint baffle guide groove is made up of otch steel pipe, and joint baffle inserts in baffle plate guide groove, and in the reinforcing cage of fluted body termination, concreting forms the first diaphragm wall; Fluted body adapter plate in boss one end and first diaphragm wall of boss shape reinforcing cage coincide, and in boss shape reinforcing cage, concreting forms the second diaphragm wall.
In joint baffle guide groove, insert Grouting Pipe, treat the second diaphragm wall build complete, its concrete strength reach design strength 70% after, extract the rubber membrane in Grouting Pipe, it is carried out to grouting.
Beneficial effect: the utility model adopts above rigid joint mode, compare and possess following advantage with existing joint: the utility model has been realized the combination construction mode of a kind of fluted body adapter plate and joint baffle, reduce the construction process reduction of erection time, make body of wall joint more tight in conjunction with fluted body adapter plate connection between more firm, body of wall without carrying out terminal bruss wall without snap close pipe and joint case technique, more simpler than conventional rigid piecer process flow.Fluted body adapter plate and joint baffle are made simple, easy construction, and joint baffle can repeatedly use, and Construction on Environment is pollution-free.
