Background
The underground continuous wall has the functions of water interception, seepage prevention, bearing, water retaining and the like, and is widely applied to foundation pit engineering. When the existing underground pipeline is encountered in the construction process of the underground diaphragm wall, the measures of cutting and modifying the underground pipeline are usually adopted, or the underground pipeline is temporarily moved to an enlarged road surface, and the underground pipeline is moved to the original position after the construction of the underground diaphragm wall is finished. However, when the underground diaphragm wall meets the underground sewage pipeline in the construction process, the sewage pipeline cannot be changed when the rainy season comes, and the construction period of the underground diaphragm wall is seriously influenced. Therefore, it is sometimes necessary to construct the underground diaphragm wall without the sewage pipe being moved.
Chinese patent No. CN105735244B proposes a construction method for designing a trough section of an underground diaphragm wall straddling an existing sewage pipe, which requires "pulling the left and right reinforcement cages by using reinforcement cage pulleys and correction wires to connect the reinforcement cages at both sides". When the depth of the underground continuous wall is large, each pair of reinforcement cages weighs several tons, the reinforcement cages on the left side and the right side are pulled in the grooves to be connected, the construction difficulty is large, and even the construction difficulty is difficult to realize. It is seen that there is a need for a practical method of constructing underground diaphragm walls straddling sewage pipes.
Therefore, when the buried depth of the sewage pipe is large (at least half of the design depth of the underground continuous wall) and the sewage pipe cannot be moved, the underground continuous wall straddling the sewage pipe formed by a reasonable construction method needs to be designed to meet the actual requirement.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
A partial reverse construction method underground continuous wall striding over a sewage pipe comprises a left cast-in-place underground continuous wall 4 outside the influence range of the sewage pipe 1, a right cast-in-place underground continuous wall 5, an upper cast-in-place underground continuous wall 7 and a lower cast-in-place underground continuous wall 8 constructed by a reverse construction method around the sewage pipe 1; the left cast-in-place underground continuous wall 4, the right cast-in-place underground continuous wall 5 and the upper cast-in-place underground continuous wall 7 are constructed by a sequential method; the lower cast-in-place underground continuous wall 8 constructed by the reverse construction method is an underground continuous wall which is formed by reverse construction from top to bottom section by section from the bottom of the upper cast-in-place underground continuous wall 7; the sewer pipe 1 is wrapped in a cast-in-place underground diaphragm wall 8 constructed by the reverse method.
The terms "left" and "right" refer to the underground continuous walls on both sides of the sewage pipe 1, and do not represent fixed directions and directions. The above-mentioned terms of orientation such as "upper portion", "bottom portion", etc. are determined based on the attitude of the underground diaphragm wall in construction. During construction, the lifted reinforcement cage is suspended above the groove and is in a plumb state, as shown in fig. 1 to 5. In this posture, the specific direction of each directional word is determined, and directional words mentioned elsewhere in the specification are also estimated according to this posture. The above-mentioned orientations or positional relationships are based on the orientations or positional relationships shown in the drawings and are only for convenience of description, but do not indicate or imply that the device or member referred to must have a specific orientation, configuration and operation, and therefore, should not be construed as limiting the present invention.
The term "outside the influence range" refers to that the influence on the sewage pipe 1 is very small when the peripheral underground continuous wall is used for digging a groove, hoisting a reinforcement cage, pouring concrete, vibrating and the like, and the sewage pipe 1 cannot deform beyond the standard due to the construction of the peripheral underground continuous wall. The definition of the "influence range" should be comprehensively determined according to specific engineering geological conditions, pipeline parameters and local experience.
The reinforcement cage in the lower cast-in-place underground continuous wall 8 needs to be welded and connected with the reinforcement in the left cast-in-place underground continuous wall 4, the right cast-in-place underground continuous wall 5 and the upper cast-in-place underground continuous wall 7. The underground continuous walls 8 constructed by the reverse construction method are tightly connected with the adjacent underground continuous walls, and the related requirements are met.
The sewage pipe 1 is wrapped in the cast-in-place underground continuous wall 8 at the lower part, and the water interception, seepage prevention and water retaining performances at the periphery of the sewage pipe 1 meet the requirements. Therefore, in the construction process of the lower cast-in-place underground continuous wall 8, the seepage prevention around the sewage pipe 1 is specially treated, so that the problem of seepage around the sewage pipe 1 cannot occur.
The load born by the cast-in-situ underground continuous wall 8 at the lower part can not be transferred to the sewage pipe 1, thereby ensuring the safety of the sewage pipe 1. If the sewage pipe 1 bears part of the load of the cast-in-place underground continuous wall 8 at the lower part, the sewage pipe 1 may be deformed too much to crack and leak, and the failure may occur, which becomes a construction accident.
The utility model discloses a service condition does: when the buried depth of the sewage pipe is larger (generally, the buried depth is half or more of the design depth of the underground continuous wall), the diameter of the sewage pipe is larger and the sewage pipe cannot migrate, the sewage pipe penetrates through the position of the underground continuous wall, and the main body of the underground continuous wall is constructed by adopting a cast-in-place and sequential method.
