Abstract
The utility model relates to a raft foundation structure of a narrow foundation power transmission tower, which is fixedly connected to footings of the narrow foundation power transmission tower. The raft foundation structure comprises a foundation plate and an installing slot, wherein the installing slot is arranged on the foundation plate and is of a #-shaped structure, and four connecting points are provided and connected with bulges of the footings of the narrow foundation power transmission tower. Compared with the prior art, the raft foundation structure has the advantages of relative simple requirement of equipment in a construction process so that earthwork exaction is carried out by adopting manual operation or mechanical operation, lower requirement of foundation rib distribution, and little influence of environment during construction.
Description
Technical field
The utility model relates to a kind of pile foundation basis, especially relates to a kind of narrow basic power transmission tower raft 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.
The utility model content
The purpose of the utility model is exactly to provide simple relatively, the basic cloth muscle of a kind of structure to require lower narrow basic power transmission tower raft 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 narrow basic power transmission tower raft foundation structure is fixedly connected on the footing place of narrow basic power transmission tower, described foundation structure by foundation slab, draw-in groove be installed constituted, described installation draw-in groove is arranged on the foundation slab.
Described installation draw-in groove is the groined type structure, and the four points of connection place is provided with the convexity that connects narrow basic power transmission tower footing.
This foundation structure connects into holistic raft foundation structure for four footing with narrow basic power transmission tower.
This foundation structure is embedded in below the face of land.
Compared with prior art, the utility model is simple relatively to equipment requirements in work progress, cubic metre of earth excavation adopt artificial, machinery all can, basic cloth muscle requires lower, and affected by environment less during construction.
Description of drawings
Fig. 1 is the main TV structure sketch map of the utility model;
Fig. 2 is the plan structure sketch map of the utility model.
Among the figure, 1 is that foundation slab, 2 is footing for draw-in groove, 3 is installed.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
A kind of narrow basic power transmission tower raft foundation structure; Its structure is shown in Fig. 1-2; Be fixedly connected on footing 3 places of narrow basic power transmission tower, foundation structure is made up of foundation slab 1, installation draw-in groove 2, and it is the groined type structure that draw-in groove 2 is installed; Be arranged on the foundation slab 1, the four points of connection place that draw-in groove 2 is installed is provided with the convexity that connects narrow basic power transmission tower footing 3.This foundation structure is in aggregates with four footing connections of narrow basic power transmission tower, is embedded in below the face of land.The main feature of the utility model is that floor space is big, buried depth is shallow.According to basic pattern characteristics, commbined foundations equipment requirements in work progress is simple relatively, cubic metre of earth excavation adopt artificial, machinery all can, basic cloth muscle requires lower, and affected by environment less during construction.
During installation, according to the soil property situation, in conjunction with iron tower corner size, the in advance inclined to one side value in basis is set rationally when foundation construction, the iron tower of avoiding non-design control occurring tilts; Attention is avoided because the ground disturbance that reasons such as machinery or job practices cause the control of foundation construction method.
Claims (4)
1. one kind narrow basic power transmission tower raft foundation structure is fixedly connected on the footing place of narrow basic power transmission tower, it is characterized in that, described foundation structure by foundation slab, draw-in groove be installed constituted, described installation draw-in groove is arranged on the foundation slab.
2. a kind of narrow basic power transmission tower raft foundation structure according to claim 1 is characterized in that described installation draw-in groove is the groined type structure, and the four points of connection place is provided with the convexity that connects narrow basic power transmission tower footing.
3. a kind of narrow basic power transmission tower raft foundation structure according to claim 1 is characterized in that, this foundation structure connects into holistic raft foundation structure for four footing with narrow basic power transmission tower.
