Abstract
The utility model relates to a grouting type reinforced filling pile foundation structure, which comprises a connecting pile, a cushion cap and a pressing pile, wherein the connecting pile is connected with the upper surface of the cushion cap in a pouring manner, the pressing pile is connected with the lower surface of the cushion cap in a pouring manner, and cement solidification layers are laid on the end surfaces and the side surfaces of the pressing pile. Compared with the prior art, the grouting type reinforced filling pile foundation structure can improve the bearing capacity of a single pile, so that the pile loading settling curve becomes gentle through grouting on a pile foundation, and the settling amount is obviously reduced; through the effects of a grouting layer such as infiltration concretion, agglutination mud cake, filling compaction, split reinforcement and the like, the soft soil body around the pile is strengthened, the boundary condition of pile-soil is improved, the bearing capacity of filling pile is improved, and the settling amount is reduced.
Description
Technical field
The utility model relates to a kind of pile foundation, especially relates to a kind of slip casting formula and reinforces the bored concrete pile foundation structure.
Background technology
Transmission line of electricity mainly contains two kinds of forms, overhead wire and underground cable lines.The investment of overhead wire body is little, and transmission capacity is big, is the particularly main mode of extra high voltage network of transmission line of electricity always.
Electric power line pole tower be supporting overhead transmission line conductor and ground wire and make between them and and the earth between keep the rod of certain distance and the structure of turriform, its security reliability is directly connected to the safe operation of whole transmission line of electricity.
Along with steady development of economy; Power demand increases year by year; National grid construction development is accelerated comprehensively; The transmission line length of having built up is from 513903 kilometers of developing into 2008 of 326215 kilometers in 2004, wherein 2005 to 2008 newly-built 55549,31455,43885,56799 kilometers respectively.To in December, 2009, obtain 500kV and the above transmission of electricity project that National Development and Reform Committee approves the construction of and just reach 58.
Along with the construction of China's extra-high voltage grid and with the applying of transmission of electricity new technologies such as many loop lines of tower road, compact line, large-section lead, the trend of the big load of electric power line pole tower, maximization is more obvious.The construction of " resource-conserving, environmentally friendly " society, the security and stability of big electrical network, the complicated unusual security reliability to tower structure of climate change, economy, environmental-protecting performance etc. are all had higher requirement, and transmission line tower structure research is faced with new challenges.
Conventional overhead transmission line outlet structure often adopts flush type foot joint form; Promptly stay and establish a rim of a cup at basic top; The herringbone steel pipe column is inserted in the rim of a cup; Adopt the concrete of high one-level label to fill rim of a cup again, fill and carry out at twice, treating that concreting for the second time forms just can carry out follow-up lead after the intensity and hang up work.Say from the construction angle, this method easy construction, the foundation construction required precision is not high, but long in time limit, for reconstruction and extension project, can cause twice power failure process successively.
The utility model content
The purpose of the utility model is exactly to provide a kind of slip casting formula that can improve bearing capacity of single pile to reinforce the bored concrete pile foundation structure for the defective that overcomes above-mentioned prior art existence.
The purpose of the utility model can realize through following technical scheme:
A kind of slip casting formula is reinforced the bored concrete pile foundation structure; Comprise and connect stake, cushion cap and piling down; Described connection stake cast is connected the upper surface of cushion cap, and the described cast of piling down is connected the soffit of cushion cap, and the end face of following piling and side are laid with the cement solidification layer.
A described center position that is located at cushion cap that connects is embedded with vertical reinforcing bar and horizontal stirrup in the connection stake.
Be embedded horizontal reinforcement in the described cushion cap.
Described piling down is provided with two, is evenly distributed on the soffit of cushion cap.
Compared with prior art, the utility model can improve bearing capacity of single pile, through slip casting on pile foundation; Make the pile load subsidence curve tend towards stability, settling amount obviously reduces, effects such as grouting layer is compacted through infiltration fixed, glued mud skin, filling, splitting reinforcement; Reinforce all soft soils of stake; Improve stake pedosphere noodles spare, improved the bearing capacity of castinplace pile, reduce settling amount.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
A kind of slip casting formula is reinforced the bored concrete pile foundation structure, and its structure is as shown in Figure 1, comprises connecting stake 1, cushion cap 2 and piling 3 down; Connect the upper surface that stake 1 cast is connected cushion cap 2, be located at the center position of cushion cap 2, be embedded with vertical reinforcing bar 11 and horizontal stirrup 12 in the connection stake 1; In cushion cap, be embedded horizontal reinforcement 21; Following piling 3 cast are connected the soffit of cushion cap 2, are provided with two altogether, and the end face of following piling 3 and side are laid with cement solidification layer 4.
The all soft soils of stake are reinforced in effects such as the grouting behind shaft or drift lining bored concrete pile foundation is compacted through infiltration fixed, glued mud skin, filling, splitting reinforcement, improve a stake pedosphere noodles spare; Improved the bearing capacity of castinplace pile, reduced settling amount, through improving bearing capacity of single pile; Reach the quantity that reduces stake, the purpose that shortens the length of stake or dwindle the diameter of stake, thus reduce the material usage on basis; The duration that shortens, reduced construction costs.
Claims (4)
1. a slip casting formula is reinforced the bored concrete pile foundation structure; It is characterized in that; This pile foundation structure comprises connection stake, cushion cap and piling down; Described connection stake cast is connected the upper surface of cushion cap, and the described cast of piling down is connected the soffit of cushion cap, and the end face of following piling and side are laid with the cement solidification layer.
