Description
Technical Field
The utility model relates to the field of electric power infrastructure construction, in particular to an assembled cross beam plate spiral pile foundation for a power transmission line.
Background
When the transmission line is wired in a mountain area, large construction machinery is difficult to enter the mountain area due to inconvenient traffic environment, for example, site geological clay does not exist or underground water is less, and a tower foundation type is usually that a pile foundation is dug or dug manually. In the prior art, the manual excavation or hole digging pile foundation is mostly adopted when the working condition environment is met, the deep foundation pit operation is mostly adopted, the underground operation condition is poor, the environment is severe, the labor intensity of constructors is high, the greater construction safety risk exists, and the construction quality is difficult to control.
SUMMERY OF THE UTILITY MODEL
In view of the above disadvantages, the present invention provides an assembled cross beam slab spiral pile foundation for a power transmission line, which is convenient to install, does not need large machinery, and has a small installation and construction amount.
The technical scheme for realizing the aim of the utility model is that the fabricated cross beam plate spiral pile foundation for the power transmission line comprises a prefabricated bottom plate and is characterized in that: the prefabricated bottom plate top still is connected with the cross beam, prefabricated bottom plate and cross beam constitute the body, the body is fixed subaerial through spiral ground pile, two roof beam bodies of cross beam are located two diagonal lines of prefabricated bottom plate respectively, the body top still is connected with prefabricated king post.
And the cross beam is formed by splicing an upper precast beam and a lower precast beam, the bottom of the middle section of the upper precast beam and the top of the middle section of the lower precast beam are respectively provided with a groove, and the upper precast beam and the lower precast beam are integrally formed by mutually buckling the two grooves.
And both ends of the upper precast beam and both ends of the lower precast beam are external angles of 90 degrees.
And the spiral ground piles are arranged around the body, sequentially penetrate through the cross beam and the prefabricated bottom plate from top to bottom and fix the body on the ground.
The utility model has the advantages that: 1. the assembly mode is adopted, large-scale engineering machinery is not needed, and the device can adapt to various working conditions. 2. The spiral ground pile is connected with the ground, so that the pile foundation does not need to be dug or dug manually, and the engineering quantity is small. 3. And a large amount of concrete stirring and pouring operations do not exist in a construction site, and the engineering quality is stable.

Detailed Description
Referring to FIGS. 1-4, the present invention will be further described with reference to the following examples.
The utility model relates to the field of electric power infrastructure construction, in particular to an assembled cross beam plate spiral pile foundation for a power transmission line, which comprises a prefabricated bottom plate 1.1 and is characterized in that: the prefabricated bottom plate is characterized in that the top of the prefabricated bottom plate 1.1 is further connected with a cross beam, the prefabricated bottom plate and the cross beam form a body 1, the body 1 is fixed on the ground through spiral ground piles 2, two beam bodies of the cross beam are respectively located on two diagonal lines of the prefabricated bottom plate 1.1, and the top of the body 1 is further connected with a prefabricated main column 3.
After the body is installed, the prefabricated main column 3 is arranged at the top of the body 1, the prefabricated main column 3 and the body can be connected through bolts, transmission line towers of different specifications can be installed on the prefabricated main column 3 according to working condition requirements, and expansibility is good.
Set up the cross beam at the top of prefabricated bottom plate 3, can with 3 upper end transmission line shaft towers of prefabricated king post weight even distribution to prefabricated bottom plate 1.1 on for whole body 1 bears the basis jointly and pulls out and push down the load, and the structure is firm, and stability is good.
And the cross beam is formed by splicing an upper precast beam 1.2 and a lower precast beam 1.3, grooves 4 are respectively arranged at the bottom of the middle section of the upper precast beam 1.2 and the top of the middle section of the lower precast beam 1.3, and the two grooves 4 are mutually buckled to enable the upper precast beam 1.2 and the lower precast beam 1.3 to form a whole.
The cross beam is formed by splicing the upper precast beam 1.2 and the lower precast beam 1.3, the transportation and the installation are convenient, and the load can be uniformly distributed on the spliced cross beam. Go up precast beam 1.2 middle section bottom and precast beam 1.3 middle section top down and have recess 4 respectively, during the installation with two recess 4 lock can, very convenient.
A further technical scheme can be that two ends of the upper precast beam 1.2 and two ends of the lower precast beam 1.3 are both provided with 90-degree external angles.
The two ends of the upper precast beam 1.2 and the lower precast beam 1.3 are designed into 90-degree external angles, the width of the edge of the cross beam is consistent with that of the edge of the precast bottom plate 1.1 after the cross beam is installed, the occupied area is effectively reduced, and the stability of the structure can be enhanced.
The further technical scheme is that the spiral ground piles 2 are arranged around the body 1, and the spiral ground piles 1 sequentially penetrate through the cross beam and the prefabricated bottom plate 1.3 from top to bottom and fix the body on the ground.
During installation, the spiral ground pile 2 is driven into the ground bottom through the small pile driver, the cross beam and the prefabricated bottom plate 1.1 can be fastened, large-scale equipment is not needed, and the engineering quantity is small.
