Problems solved by technology

At the same time, the construction of lattice columns is often carried out by the subcontractors of the pile foundation. It is difficult to control the construction quality. At the same time, the extrusion of the tower crane lattice columns on the construction site is large, which is likely to cause problems such as inclination and deformation of the lattice columns, making it suitable for 10m The reinforcement construction of the tower foundation of the above-mentioned high pile cap ensures the safety and reasonableness of the panel-type lattice columns, ensures the safety and reliability of the tower crane, meets the safety calculation requirements, and realizes the reinforcement of the tower crane foundation.

Embodiment 1

[0033] A construction method for strengthening the tower foundation of high pile caps with improved reliability, such as figure 1 , including the following steps,

[0034] Set vertical strips and horizontal supports 2 between the lattice columns 1;

[0035] According to the verticality of the lattice column 1, adjust the combined structure of the vertical strips;

[0036] The horizontal support 2 is set at the same level as the floor reinforcement, and the floor reinforcement and formwork are installed continuously and at intervals at the lattice column 1, and the concrete and the floor are poured synchronously at the lattice column 1.

[0037] The reinforcement structure of the above-mentioned high pile cap tower foundation reinforcement construction method that improves reliability, such as figure 2 and Figure 4 to Figure 8 , including lattice columns 1, the number of lattice columns 1 is usually four, the exact number is determined by the number of pile foundations, ad...

Embodiment 2

[0041] The construction method for strengthening the tower foundation of the high pile cap with improved reliability described in Embodiment 1 can further adjust the combined structure of the vertical strips into a Z-shape according to the verticality of the lattice column 1 .

[0042] Then the reinforcement structure of the above-mentioned high-pile cap tower foundation reinforcement construction method for improving reliability can also be further, the combined structure of the vertical strips is Z-shaped.

Embodiment 3

[0044] The high-pile cap tower foundation reinforcement construction method of improving reliability described in embodiment 1 can also be further, such as image 3 and Figure 4 ,and Figure 6 and Figure 7 , according to the verticality of the lattice column 1, adjust the combined structure of the vertical strips to be a cross shape.

[0045]Then the reinforcement structure of the above-mentioned high pile cap tower foundation reinforcement construction method that improves reliability can also be further, such as figure 2 The combined structure of the vertical stripes is a cross shape.

Abstract

The invention discloses a high-pile cap tower footing reinforcing construction method capable of increasing the reliability and a reinforcing structure thereof. The construction method comprises the steps of arranging vertical and horizontal lacing bars between latticed columns; adjusting the length of the exposed parts of the latticed columns according to the earth excavation depth; adjusting thecombined structure of the vertical lacing bars according to the perpendicularity of the latticed columns; and arranging the horizontal lacing bars in the same elevation positions of floor rebars, continuously installing the floor rebars and formworks at the latticed columns at intervals, and synchronously pouring concrete and a floor at the latticed columns. The high-pile cap tower footing reinforcing construction method is suitable for high-pile cap tower footing reinforcing construction with the height being 10 m or above, the safe and reasonable batten plate type latticed columns are guaranteed, the safety and reliability in use of a tower crane are guaranteed, the safety calculation requirement is met, and the tower crane foundation is reinforced.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a construction method for reinforcing a tower foundation of a high pile cap with improved reliability and a strengthening structure thereof. Background technique [0002] With the increase of foundation pit area and the increase of deep foundation pit projects, in order to meet the transportation of materials in deep foundation pits and the construction period requirements of the project, the tower cranes used mostly adopt the form of high pile cap foundation, in order to ensure the safety and security of tower cranes. Reliability, and to meet the safety calculation requirements, the foundation of the tower crane must be reinforced. In order to meet the transportation of materials in the deep foundation pit and the construction period requirements of the project, the project mostly adopts the form of tower crane high cap foundation. The composite founda...
