Description
Technical Field
The invention relates to the technical field of lattice column accurate positioning devices, in particular to a reusable lattice column accurate positioning device.
Background
During construction of deep foundation pit engineering, a high-quality foundation pit maintenance structure is often constructed in advance before foundation pit construction so as to ensure stability of the foundation pit during the whole construction period, and the safety of the foundation pit can be multiplied by the high-quality maintenance structure.
When the underground continuous wall is constructed in the fields of soft soil, quicksand, high water level and the like, the underground continuous wall and the inner support mode are the preferred enclosure structure in view of safety. In foundation pit engineering with large span, the first support has large stress, a concrete support mode is generally adopted, and lattice columns are required to be arranged below the concrete support as supports in consideration of the span of the concrete support. Taking a wide channel project as an example, the cross section dimension of the concrete support is 0.8m × 1.0 m, the cross section dimension of the concrete support connecting beam is 0.5 m × 0.8m, the diameter of the lattice column pile foundation is 1.2 m, the cross section dimension of the lattice column is 0.5 m × 0.5 m, and the diameter of the pile foundation casing is 1.3 m. The allowable positioning deviation of the lattice column is very limited, and after the allowable positioning deviation exceeds the design tolerance, the lattice column deviates from the range of the concrete support structure, so that the erection position fulcrum of the concrete support is influenced, the axial stress direction of the concrete support is changed, and the safety of a foundation pit is seriously damaged even.
In the past common pile foundation construction, the circular reinforcement cage only needs to control the central position of the pile casing and the central position of the reinforcement cage. The pile casing is on the ground, and the pile casing can be accurately positioned through ground control points, so that the position of the reinforcement cage can be basically ensured not to deviate from the design allowable range. The requirement on the precision of the construction plane position of the lattice column is relatively high, the lattice column has a requirement on the direction, and the edge of the lattice column and the direction of a foundation pit need to be straight so as to ensure that the steel connecting beam can be smoothly welded. The lattice column size protects a section of thick bamboo for the pile foundation a little a lot, and in lattice column and pile foundation steel reinforcement cage welding process, there is very big deviation moreover, and the lattice column is transferred and is accomplished the back, and the capital elevation is located the concrete support bottom, apart from the flat ground height of field about 1.5 meters ~ 2.0 meters distance, and is located below the mud liquid level, the position and the direction of unable accurate positioning lattice column.
To traditional point location measurement pile location work load big, be difficult to the control accuracy, the specialty requires highly, needs professional survey personnel to pay close attention to constantly, constantly measures the condition of inconvenience such as recheck point location, utilizes on-the-spot old and useless bamboo offset plate, according to lattice column hole size, processes a wooden light repeatedly usable's lattice column joint, when lattice column is transferred to protecting a section of thick bamboo elevation, inserts lattice column with this joint in, continues to transfer lattice column to design elevation. And (4) rotating the latticed column according to the ground positioning line until the center and the direction of the joint can meet the design requirements, completing the procedure, pulling out the joint, and beginning the next procedure to pour concrete.
Therefore, we propose a reusable lattice column accurate positioning device to solve the above disadvantages.
