At the time of construction, the construction interface can meet the design requirements of tight joints, avoiding the problem of poor stability of the integrally formed T-shaped trench stratum, effectively improving the lateral deformation of the buttress or the mid-wall to suppress the continuous wall and enhance the bearing or anti-floating function. . [Prior Art] © The τ-type interface between the previous continuous wall and the buttress or the middle wall is divided into two types: (1) T-shaped unit integrally formed with the continuous wall (the disadvantages are as follows) 1. Unit division and The level of construction technology is relatively high. 2. When the middle wall or the buttress side is the first construction unit, please refer to (Fig. 1) for the cutter teeth and arc shape (15) of the excavator (10). At the time of excavation, the continuous wall (20) is close to the outside of the base (30), leaving residual soil that cannot be cleaned (35), which affects the verticality of the subsequent construction of the unit. If excessive use of the guide plate maintains the verticality of the excavation It may also cause corners or collapses in the corners of the T-shaped groove (40), please refer to (Fig. 2(a), (b)). 3. The T-shaped groove (4〇) has poor stability, long construction time, and easy corner or collapse of the groove. If the collapse occurs during the excavation stage, the excavator (10) may be buried; if the collapse occurs during the concrete placement stage: the integrity and water tightness of the continuous wall (20) wall structure will be affected. 4. For the continuous wall (20) T-shaped unit, if the middle wall or the buttress (25) side is the mother element, the technical requirements and precision requirements of the steel cage processing are higher, and the consumption is longer than 200930863. In addition, due to the weight of the end turns and the length of the joints, the weight of the steel cages is not balanced, which affects the verticality of the steel cages when they are suspended, which may cause difficulty in lifting or scratching the walls. 5. Continuous wall (2〇) Τ type unit, in which one side is the mother unit, in the case of easy cornering or collapse at the ridge of the τ plastic groove (40), it is easy to cause slurry leakage during the concrete pouring stage. 6. Excavation stage Τ type interface stone (concrete knockout), in addition to mechanical stone, at the interface to avoid injury and continuous wall (2 〇) need to use artificial stone to repair the wall to maintain flatness, disposal is more labor-intensive time consuming. 7. During the excavation stage, the rock-type vibration of the Τ-type interface is large, which has a great influence on the watertightness of the adjacent building and the continuous wall (20). (2) The buttress or the inner wall of the wall which is separated from the continuous wall (the shortcomings are as follows). The local part of the guide wall or the interbedded layer of the geological interfacial layer, after the completion of the concrete washing, the resulting wall body (45) phenomenon And because the excavator (10) grab can not effectively remove the residual soil (35) between the buttress or the interface between the middle wall (25) and the continuous wall (20), the thickness of the soil sandwiched by the interface can reach 20cm~30cm, please As shown in the third figure (a), (b), this will result in the inability of the buttress or the mid-wall (25) to function as originally supported. In the construction, the residual soil (35) of the crack is treated. Generally, the grouting is applied between the buttress or the middle wall (25) and the continuous wall (2〇). If the bottom of the guide wall or the local stability is poor, the geology is poor. In the case of collapse, after the concrete is washed and hardened, the resulting wall body (45) and the inclined surface often cause the drilling to be skewed or cause the problem of the drill pipe jam. The grouting effect is difficult to grasp, and the result may not be as expected. 6 200930863 [Description of the Invention] In view of this, the purpose of this creation is to provide a T-groove (40) that can avoid the T-groove (40) excavation. When the stability of the formation is poor or the construction time is long, the T-shaped groove (10) is generated. When the problem of the collapse or the inner wall (10) is separated from the continuous wall (10), the buttress or the middle wall (10) cannot effectively remove the buttress or the middle wall due to the excavator (10) grab (10)
