Description
Technical field
The present invention, about a kind of construction technology of diaphragm wall, refers in particular to a kind of GXJ diaphragm wall rubber water proof joint tool and job practices thereof.
Background technology
The sixties in 20th century, underground continuous wall construction technique was introduced into China, rigidity is large, the anti-leakage performance is good owing to having, can load-bearing and characteristics such as friction, noiseless during construction, and can and be suitable in multiple soil layer construction near the building edge, thereby be widely used in subway station, more in the engineerings such as Jiang Tongdao, High-Rise Building Deep Foundation and antiseepage dam, become the space enclosing structure of excavation of foundation pit or the part of permanent structure.
The body of wall joint of subterranean wall refers to and sets when current construction groove section is built walls concrete, the vertical jointing combined with walls concrete that the adjacent channels section is built.Though diaphragm wall is called " diaphragm wall ", but be minute grooving of groove section and a concreting during construction, during the groove section of formerly constructing construction, how at groove section two ends, to place joint tool to form well-formed's joint, make it avoid becoming approach and the intensity hidden danger point of percolating water.Therefore, the joint construction quality of diaphragm wall is very crucial.
Whole nation deep foundation ditch diaphragm wall is gone along with sb. to guard him all ubiquity percolating water phenomenons of engineering, and diaphragm wall percolating water also can cause the underground structure infiltration, and the annual underground construction leaking-stoppage fees such as basement, subway station that are used for are with countless.And diaphragm wall percolating water is mainly in joint, on market underground wall joint have common flexible joint that locking notch pipe joint, joint pile joint are arranged, exempt to brush the wall composite-joint, the multi-form joint such as the nested rigid joint of reinforcing cage, these joints increase if dealt with the probability that all can make percolating water improperly.
Summary of the invention
Because the problems referred to above the invention provides a kind of GXJ diaphragm wall rubber water proof joint tool, leading portion construction groove section and back segment construction groove section be used to connecting described diaphragm wall comprise:
One joint case, described joint case forms an end face with continuous turnover curve near the end of described leading portion construction groove section along the width of groove section, and along the length direction of groove section, further is formed with a groove near the end of described leading portion construction groove section;
One rubber water proof band, the first end of described rubber water proof band is embedded in described groove, and the second end of described rubber water proof band is exposed at outside described groove.
The further improvement of this joint tool is, described joint case is connected with a partition panel near the end of described back segment construction groove section, and the width of described partition panel is less than the width of described leading portion construction groove section.
The further improvement of this joint tool is, the two ends of described rubber water proof band are embedded with respectively a steel sheet.
The present invention also provides a kind of construction method of underground continuous wall that utilizes this GXJ diaphragm wall rubber water proof joint tool, comprises the following steps:
(1), by the described leading portion construction of grooving equipment excavation groove section, near the end of the back segment construction groove section of also not excavating, place a joint tool in leading portion construction groove section;
(2), after slurry is changed in clear hole, put into reinforcing cage in leading portion construction groove section, and concreting;
(3) after the concrete setting of leading portion construction groove section, excavation back segment construction groove section;
(4) behind clear hole, take out the joint case of joint tool, form the joint with continuous turnover curve, and the second end of described rubber water proof band is embedded in the concrete of completed leading portion construction groove section admittedly;
(5) in back segment construction groove section, place a joint tool near the end of the adjacent slot section of also not excavating;
(6), after slurry is changed in clear hole, put into reinforcing cage in back segment construction groove section, and concreting, with the concrete of completed leading portion construction groove section, be connected;
(7) after the concrete setting of back segment construction groove section, the first end of described rubber water proof band is embedded in this section concrete admittedly, completes leading portion construction groove section and constructs being connected of groove section concrete with back segment;
(8) the described adjacent slot section of excavation, behind clear hole, take out the joint case of joint tool, and repeating step (5)～(7), until complete the construction of whole diaphragm wall.
The further improvement of the method is, described joint case is connected with a partition panel near the end of described back segment construction groove section, and the width of described partition panel is less than the width of described leading portion construction groove section.
The further improvement of the method is, the two ends of the corresponding described partition panel of described grooving equipment are respectively equipped with a buckle ear, and described grooving equipment fastens described partition panel by described buckle ear, and the joint case of described joint tool is taken out.
GXJ diaphragm wall rubber water proof joint tool of the present invention, extended the seepage action of ground water circuit that may occur by the laterally continuous turnover curve of joint case and the rubber water proof band vertically arranged.Similar with other joint forms on job practices, just different on the time at the taking-up joint tool, in the construction of general joint, after the concreting that has completed leading portion construction groove section, the method adopted is first to take out joint tool, then excavate back segment construction groove section, and the method that the present invention adopts is, first excavate back segment construction groove section, then take out joint tool, like this, when excavation back segment construction groove section, just can not have influence on the concrete quality of the leading portion construction groove section completed.After taking out joint tool, one end of rubber water proof band is fixed in the concrete of completed leading portion construction groove section, and, the other end be exposed is fixed on when building the concrete of back segment construction groove section in, realize the effect of water proof sealing, form the joint with stagnant water effect.
