Problems solved by technology

The above scheme solves to a certain extent the problem that the existing cement-soil mixing pile machine cannot transport various slurries to the drill pipe, but this scheme still exists: the slurry is not evenly distributed, and the drill pipe needs to be connected to the distributor when it is lifted. , the problem of poor stability

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] like Figure 1-7As shown, the material delivery sealing box of the cement-soil mixing pile machine includes a main body sealing box 1, and the main body sealing box 1 is provided with a main rod through hole 11 and at least two auxiliary rod through holes 12 along the vertical direction. The main rod through hole 11 is pierced with a main drill rod 2 capable of circumferential rotation and axial reciprocating movement, and the auxiliary rod through hole 12 is pierced with an auxiliary drill rod 3 capable of circumferential rotation and axial positioning. A movable sealing box 4 is arranged above the body 1, and a main rod installation hole 41 is arranged in the vertical direction in the movable sealing box 4, and the main drill rod 2 is penetrated in the main rod installation hole 41 and connected with the main rod installation...

Abstract

The invention relates to a material conveying seal box for a cement mixing pile driver. The material conveying seal box solves the problems that materials are unevenly fed when an existing cement mixing pile driver is used for drilling holes. The material conveying seal box comprises a main seal box body, a main rod penetrating hole, at least two auxiliary rod penetrating holes, a main drill rod, auxiliary drill rods, a movable seal box body and a main rod installation hole. At least two main rod conveying pipes are arranged in the main drill rod. At least two main rod feeding inlets are formed in the movable seal box body, and a main rod feeding mechanism is arranged in the movable seal box body. At least two auxiliary rod conveying pipes extending downwards in the axial direction are arranged in each auxiliary drill rod. At least two auxiliary rod feeding inlets are formed in the main seal box body, and an auxiliary rod feeding mechanism is arranged in the main seal box body. The material conveying seal box has the advantages that slurry is evenly distributed; a distributor does not need to be lifted up along with the drill rods which are lifted up; additives can be conveyed into the conveying pipes in the drill rods at the same time in construction, material feeding is smooth, and the additives in the conveying pipes in the drill rods are evenly distributed.

Description

technical field [0001] The invention belongs to the technical field of construction equipment, in particular to a material delivery sealing box of a cement-soil mixing pile machine. Background technique [0002] The cement-soil mixing pile is a method for reinforcing the low foundation of saturated soft clay. It uses cement as the curing agent, and through a special mixing machine, the soft soil and the curing agent are forced to mix deep in the foundation. A series of physical and chemical reactions between them make the soft soil harden into a high-quality foundation with integrity, water stability and certain strength. In order to reduce the resistance when drilling, the existing cement-soil mixing pile machine usually performs operations such as grouting and air filling in the borehole during drilling. During construction, it is necessary to equip each drill pipe with multiple A feeding pipe is fed to the feeding pipe through multiple feeding mechanisms so that the slur...
