Abstract
The construction method of the present invention includes cutting stone into one block or two blocks to be assembled in the designed size, drilling holes for foundation bolts; hoisting the stone into the foundation pit, back filling and densifying; fixing the foundation bolts; and assembling the pole or tower in the method similar to fixing railway tracks. The said method can be used in construction electrical power pole and tower as well as other buildings in cold area in winter.
Description
The invention belongs to the construction of power engineering pole and tower foundation adopts rubble to substitute the poured in place concrete foundation construction method.
The prior art power engineering shaft tower built-up foundation of setting up routinely all is the concrete foundation of cast in situs by design, selecting for use of its medium sand, building stones, reinforcing bar, the cement and the water ratio requirement that are applicable to highland and severe cold are very strict, after building, concrete foundation to pass through preserving period, reaching the shaft tower assembling that just can carry out after designing quality requires more than the basis, needing after the often basic cast in situs just can reach prescribed strength more than 28 days.And on-the-spot proportioning to cement, sand, stone, water also is difficult to grasp, also Qinghai-Tibet Railway this natural conditions very under the condition of severe construction be difficult to ensure the quality of products.
The objective of the invention is to for outside the deficiency that overcomes above-mentioned prior art, especially construct because of being subjected to the influence of natural conditions in the Qinghai-Tibet Railway power engineering, cause the construction period short, long construction period, programming and difficult quality guarantee, therefore at Qinghai-Tibet Railway natural conditions and construction particularity duration to engineering construction, progress, quality is because the unfavorable factor that environment brings has been carried out thematic tackling key problem, and according to the experience of constructing for many years in Qinghai-Tibet Railway and grasping, examination, checking thinks that can make full use of natural rubble is the basis that can substitute poured in place concrete fully as the power engineering pole and tower foundation through the exploitation back, it is short convenient to have the construction haul distance, characteristics such as on-the-spot easily grasp.Technical method of the present invention is: this method is the pole and tower foundation size of giving by design department, the stone cutting is become an integral body that conforms to size with designing institute, bigger basis is divided into two parts up and down, installed surface intelligibility chipping, and press the shaft tower installation requirement, the stone bolt hole drill is good, transport the scene to, hang in the foundation pit that digs by design, after backfill and the compacting shaft tower stone bolt is fixed, by the railway concrete sleeper fixedly track bolt construction method (sulfur cement mortar anchorage method) carry out site operation, just can carry out the shaft tower assembly working immediately.Technique effect of the present invention: component on site construction method of the present invention simply, easily grasp, need not to carry out cumbersome preparation of construction, get the raw materials ready.And will dig good rubble-mound foundation and transport the scene to, in place, installing only is about 4 hours, just can carry out the above work in basis, the concrete foundation more cast-in-place than the scene saved time and reached 668 hours, saved the time greatly, improved construction efficiency, accelerating construction progress.With shaft tower formation integral body in back is being installed because of pole and tower foundation, shaft tower produces power to the basis, is shaft tower self, and the weight of insulator, lead and the bending moment force that produced by wind-force act on foundation bearing capacity.Do not have excessive impact force, from building stones natures intensity, the hardness integrality, easily exploit pollution-free, select fully can with concrete foundation one's deceased mother U.S., can reach the select requirement of design fully to pole and tower foundation.And be not subjected to after the interference of external environments such as time, season, weather and influence, and have higher anticorrosive, cold resistance.Highland and severe cold area and winter time carry out constructional difficulties under the long natural environment ten minutes unfavorable conditions thereby effectively solved, overcome the unfavorable factor of bringing in the cast of frozen soil layer section concrete basis.The harm of natural zone is given in improvement because of cast-in-place concrete.The construction works quality, benefit is improved greatly.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
Below the present invention is described in further detail: as shown in drawings to closing the given embodiment of accompanying drawing, this method is: by the pole and tower foundation size that design department gave, stone 1 cutting is become an integral body that conforms to size with designing institute, (bigger basis can be divided into two parts up and down) installed surface intelligibility chipping, and press the shaft tower installation requirement, the stone bolt hole drill is good, transport the scene to, hang in the foundation pit 3 that digs by design, after backfill and the compacting that shaft tower stone bolt 2 is fixing, by railway coagulate native sleeper fixedly track bolt construction method (sulfur cement mortar anchorage method) carry out site operation, just can carry out the shaft tower assembly working immediately.Utilize the rubble-mound foundation to substitute concrete cast-in-site basis, from component on site construction method simply, easily grasp, need not to carry out cumbersome preparation of construction, get the raw materials ready.And will dig good rubble-mound foundation and transport the scene to, in place, installing only is about 4 hours, just can carry out the above work in basis, the concrete foundation more cast-in-place than the scene saved time and reached 668 hours, saved the time greatly, improve construction efficiency, accelerated construction speed.
