Abstract
The utility model discloses a pre-stressed concrete pipe pile foundation for a pole and tower of a power transmission line. The pre-stressed concrete pipe pile foundation is characterized in that two or more than two micro pipe piles are arranged into a pile group in the foundation, wherein the distance between every two adjacent micro pipe piles is 3-5 d; d is the diameter of each micro pipe pile; each micro pipe pile is a pipe pile of which the diameter is not greater than 300 mm and the pile length is 3-6 m; and a reinforced concrete bearing platform and a stand column are formed on the upper part of the pile group through pouring. The high-strength pre-stressed concrete pipe pile is applied to the pole and tower foundation of the power transmission line, so that the pile body quality is effectively guaranteed, the construction is facilitated, the consumption of the concrete is effectively reduced, the construction spoil is reduced, and the foundation is an energy-saving and environment-friendly foundation form.
Description
Technical field
The utility model relates to a kind of high strength prestressed concrete pipe pile basis, more particularly in particular for the high strength prestressed concrete pipe pile basis of electric power line pole tower.
Background technology
At present, high strength prestressed concrete pipe pile has been widely used in industry and the engineerings such as civilian construction, railway, highway, bridge and harbour.In power industry, pile tube is mainly used in power plant, the transformer station basis.Because the power transmission line column position disperses, foundation construction place conditions of transportation is poor, the construction plant geological conditions is complicated and changeable, tube pile construction machinery mainly contains static pressure machine and impact pile driving machine at present, but mechanical build is bigger, is difficult to enter ungetable tower position, admission fee is used less economical in the electric power line pole tower Foundation Design with high.Generally more than 400mm, weight is bigger for the pipe fitting diameter of pile tube commonly used in the engineering, needs mechanical coordinative constructions such as oversize vehicle and crane, therefore also can't extensively adopt in work transmission line.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of electric power line pole tower pre-stressed concrete pipe pile foundation is provided, applying so that high strength prestressed concrete pipe pile can access on the transmission line of electricity basis.
The utility model adopts following technical scheme for the technical solution problem:
The design feature of the utility model electric power line pole tower pre-stressed concrete pipe pile foundation is: adopt the miniature pile tube more than two or two to be arranged to a clump of piles in the basis, the spacing of adjacent miniature pile tube is 3 ~ 5d, and d is miniature pile tube diameter; Described miniature pile tube is the pile tube that diameter is not more than 300mm, the long 3 ~ 6m of being of stake; Build on the top of a described clump of piles and to form steel concrete cushion cap and column.
The design feature of the utility model electric power line pole tower pre-stressed concrete pipe pile foundation also is:
The pile crown of described miniature pile tube is provided with end bracket and pile tube cuff, and configuration stake end anchor rib.
Described column is the right cylinder type, and anchoring stone bolt in described cushion cap and column is connected with the top shaft tower with described stone bolt.
Described column is the batter post type, and anchoring oblique cutting angle steel in described cushion cap and column is connected with the top shaft tower with described oblique cutting angle steel.
Compared with the prior art, the utility model beneficial effect is embodied in:
The utility model makes high strength prestressed concrete pipe pile be applied to the electric power line pole tower basis; can effectively guarantee pile quality; the transportation of convenient construction machinery and pile tube material; shorten the construction period on basis; the tube pile construction process need not earth excavation and discharging mud, is conducive to protect basic surrounding enviroment, effectively reduces the concrete consumption; reducing the construction spoir, is a kind of basic pattern of energy-conserving and environment-protective.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is another embodiment structural representation of the utility model;
Number in the figure: 1 miniature pile tube, 2 cushion caps, 3 columns, 4 cushion cap reinforcing bars, 5 column reinforcing bars, 6 stone bolt, 7 oblique cutting angle steel.
The specific embodiment
Referring to Fig. 1, the electric power line pole tower pre-stressed concrete pipe pile foundation is to adopt the miniature pile tube 1 more than two or two to be arranged to a clump of piles in the basis in the present embodiment, and the spacing of adjacent miniature pile tube is 3 ~ 5d, and d is miniature pile tube diameter; Miniature pile tube 1 is the pile tube that diameter is not more than 300mm, the long 3 ~ 6m of being of stake; Build on the top of a clump of piles and to form steel concrete cushion cap 2 and column 3.
In concrete the enforcement, column 2 can be two kinds on right cylinder type and batter post type:
As shown in Figure 1, column 3 is set is the right cylinder type, anchoring stone bolt 6 in cushion cap 2 and column 3 is connected with the top shaft tower with stone bolt 6.
As shown in Figure 2, column 3 also can be set be the batter post type, anchoring oblique cutting angle steel 7 in cushion cap 2 and column 3 is connected with the top shaft tower with oblique cutting angle steel 7.
Miniature pile tube is prefabricated component, and pile body adopts the centrifugal process moulding, and pile body prestressing force master muscle is cold-drawn low-carbon wire, adopts pre-tensioning system to apply prestressing force.
Be provided with pile body prestressing force master muscle in the miniature pile tube, be provided with spiral stirrup at the excircle of pile body prestressing force master muscle, interior week erection hoop reinforcement is set at pile body prestressing force master muscle; Be to improve the resistance to plucking ability of pile tube, the pile crown of miniature pile tube is provided with end bracket and pile tube cuff, and a configuration stake end anchor rib, when needs carry out two sections miniature pile tubes butt joints, at first finishes the welding of butt weld between the end bracket, and weld all around outside afterwards is fishplate bar in succession.
In the present embodiment, the weight of single miniature pile tube is not more than 131kg/m, is convenient to transportation.Because the stake footpath is little, reduced the bearing capacity of single pile, can reduce the requirement to the pile follower ability of piling machinery; Illustrated in figures 1 and 2 is to form a clump of piles with four miniature pile tubes, and the mini pile pipe adopts cross stake point, uses the ringing engine tool to carry out hammer piling, carries out piling construction as adopting diesel hammer or hydraulic hammer in the mode of hammering.
When all miniature pile tubes in the basis after all pile sinking finishes on request, according to geological condition, sand need stop 7 days, and silt and saturated cohesive soil need stop 15 days, carried out the excavation of foundation pit operation then, and excavation spoir piling height around foundation ditch can not surpass 1m.
Excavation of foundation pit is during to the designing requirement size, colligation cushion cap reinforcing bar 4 and column reinforcing bar 5, and the pile crown of miniature pile tube gos deep into cushion cap 100mm, and model of the column is made in stone bolt 6 or 7 installations in place of oblique cutting angle steel; Concreting subsequently adopts machinery to vibrate, and finishes the back in cushion cap and column concreting base concrete is carried out maintenance, and reaching design strength 70% can split tower erection, reaches design strength 100% and carries out integral body and found tower.
