Problems solved by technology

[0008] In the gantry structure using steel pipe piles, in the prior art, the anchorage length of the steel pipe piles is guaranteed by the depth of the steel pipe piles entering the covering layer. However, under some geological conditions, the inserted steel pipe piles cannot reach The depth of the covering layer is set, so its anchoring fastness cannot be guaranteed; in

Embodiment Construction

[0021] see figure 1 , figure 2 , in the present embodiment, in the cofferdam, at the location of each gantry steel pipe pile 1, a borehole deep to the rock surface is set, and each gantry steel pipe pile 1 supports the rock in the borehole by vibrating. On the surface; between the gantry steel pipe piles 1, the longitudinal section steel 2 and the transverse section steel 3 are respectively connected to form a bottom frame with the gantry steel pipe pile 1 as the opposite side, and the bottom frame is pre-buried in the bottom cover of the cofferdam In the concrete layer 8 , on the level of the back-sealing concrete layer 8 , on the periphery of each steel pipe pile 1 of the portal frame, two integral buttresses 9 of steel pipe piles on opposite sides are formed with poured concrete.

[0022] In the specific implementation, both the longitudinal section steel 2 and the transverse section steel 3 adopt "I"-shaped steel. In order to ensure the firm connection between the gantry...

Abstract

The invention discloses a bearing reaction restraining fixed structure of a height crane gantry, characterized in that drilling holes deep to a rock surface are arranged in the positions of gantry steel pipe piles in a cofferdam, the gantry steel pipe piles are supported on the rock surface in the drilling holes in a vibration mode and mutually connected respectively through longitudinal profile steel and transversal profile steel to form a bottom frame by using the gantry steel pipe piles as opposite edges, the bottom frame is pre-buried in a sealing concrete layer of the cofferdam, and concrete is cast on the periphery of the gantry steel pipe piles on the bedding of the sealing concrete layer to form an integral buttress of the gantry steel pipe piles of the two opposite edges. Aiming at the condition that the anchorage depths of the steel pipe piles can not reach the set requirements, the gantry height in the invention can reach a special condition of 100 m so that the invention can effectively ensure the stability of the gantry structure and the construction safety.

Description

technical field [0001] The invention relates to a fixing structure of a hoisting door frame in the construction process of a tower structure, which is used for stably hoisting the door frame. Background technique [0002] For the construction of tower structures, the hoisting portal method has many advantages, including: [0003] 1. The mast erecting materials are easy to purchase, can be purchased at any time, and can be used in subsequent construction; [0004] 2. Compared with other equipment, the cost of door frame construction is less, cost saving and stable in structure; [0005] 3. It is easy to adjust in place when installing the main tower section. [0006] At the same time, realizing the stability of the hoisting gantry and saving the project cost has become an important issue for the hoisting gantry of the high main tower. The stability of the hoisting gantry of the main tower is directly related to the safety of the hoisting operation of the main tower. If it ...
