TECHNICAL FIELD

[0001] The application belongs to the field of diaphragm wall trenching machine equipment, and particularly relates to a self-locking diaphragm wall double-side rotary drilling and digging transverse trenching machine. BACKGROUND

[0002] The underground continuous wall is a continuous reinforced concrete wall built by the method of pouring concrete into the guide pipe in sections after the trench is excavated along the edge of the foundation engineering on the ground, the trench is cleaned and the reinforcement cage is hung, under the premise of mud protection wall in the foundation engineering construction. The underground continuous wall is mainly used as a water interception, seepage prevention, load bearing, water retaining structure or as a foundation of a building.

[0003] The existing trenching technology mainly includes excavator type and milling wheel type. Patent No. CN 114687393A "Continuous wall construction equipment and construction method thereof" realizes the joint circulation of rotary drilling and grab bucket to drill the diaphragm wall trench. Patent No. CN 110258693A "Hydraulic grab bucket and underground continuous wall construction equipment" realizes the switching between the hydraulic grab bucket and the double-wheel mill through the movable buckle and the connecting piece, realizes one machine with multiple functions, and drills the underground continuous wall trench. In order to realize the construction of the diaphragm wall in low clearance, Patent No. CN 114086618A "Modularized trench milling device for underground diaphragm wall construction" modularizes the functional components of the diaphragm wall trenching equipment into a milling module, a slurry pumping module, a winding and hoisting module, and a accessory reel module, and sequentially connects and lays them on the track from front to back. Patent No. CN 115070953A "Trenching equipment for underground continuous wall construction in building engineering" hoists the synchronous milling and hydraulic cutting equipment between the two bearing vehicles through the row frame to prevent the trench hole from being collapsed by the horizontal pressure caused by the bearing vehicle, and improve the trenching quality and the stability of the trench hole.

[0004] The existing diaphragm wall trenching machine solves some problems of diaphragm wall trenching, but still has the following problems: (1) The diaphragm wall needs auxiliary equipment for deslagging, such as excavator type, which needs to be continuously lifted up and down in the trench to excavate and discharge the soil, and the construction efficiency is low; (2) It is impossible to realize the excavation of the horizontal diaphragm wall / plate structure trench in the rock-soil body.

One end of the sludge suction main pipe 51 is connected in communication with the sludge suction port of the stirring box 31 through the crushing device 4. The other end (i.e. the suction end) of the sludge suction main pipe 51 is bifurcated into the vertical sludge suction branch pipe 52 and the horizontal rotary sludge suction branch pipe 53. Figure 2As shown, the vertical sludge suction branch pipe 52 extends into the vertical drilling device 1, and the suction head 55 of the vertical sludge suction branch pipe 52 is close to the cylindrical drilling assembly 11, so that it can suck the soil sludge stirred by cutting, and the vertical sludge suction valve 56 is arranged at the suction head 55 for controlling the opening and closing of the pipeline. The horizontal rotary sludge suction branch pipe 53 extends into the horizontal rotary drilling assembly 2, and the suction head 55 of the horizontal rotary sludge suction branch pipe 53 is close to the horizontal rotary drilling device 21, so that it can suck the soil sludge stirred by cutting, and the horizontal rotary sludge suction valve 57 is arranged at the suction head 55 for controlling the opening and closing of the pipeline, wherein part of the pipeline of the horizontal rotary sludge suction branch pipe 53 is in the form of an extension pipe 54 to adapt to the rotation of the horizontal rotary drilling device 21.

The fan motor 45 is installed on the top plate in the crushing box 41 through the rack 44, and the fan blades 46 are arranged on the rotating shaft of the fan motor 45. The high-speed rotating fan motor 45 and fan blades 46 can form a negative pressure suction in the sludge main pipe 51, and the crushing knives 47 are installed at the installation position of the fan motor 45, so that the sucked sludge must pass through the crushing knives 47 before entering the mixing box 31 through the connecting pipe 43. The filter screen 48 is arranged at the end surface of the fan motor 45 to filter large particle sludge, so as to avoid the sludge flowing into the mixing box 31 from the fan motor 45.

[0073] The slurry inlet of the mixing box 31 is connected to the grouting system 6 on the ground, and the grouting system 6 mainly includes a grouting pipe 61 and a grouting pump 62. The grouting pipe 61 pumps the slurry with a suitable concentration into the mixing box 31 through the grouting pump 62, mixes with the sludge sucked up, and becomes a liquid, which is convenient for sucking outwards.

[0074] The sludge outlet of the mixing box 31 is connected to the sludge discharge system 7 on the ground, and the sludge discharge system 7 includes a sludge discharge pipe 71 and a sludge discharge pump 72. The lower end of the sludge discharge pipe 71 is connected to the sludge outlet of the mixing box 31 and extends downward to a certain depth, so as to facilitate the discharge of more slurry.

[0082] (S6) According to step S5, the drilling and digging of the remaining three vertical diaphragm wall slots c1 and their corresponding horizontal cantilever slab slots c4 are completed, thereby realizing the drilling and digging of the diaphragm wall slot c. In addition, as shown in Figure 18 , the top surface of the horizontal cantilever slab slot c4 is flush with the bottom surface of the deep foundation pit.
