Description
[technical field]
The present invention relates to transmission line construction field, especially relating to a kind of by drawing the construction method scraping out hole formation transmission line foundation.
[background technology]
Known, a kind of foundation pattern generally adopted when digging hole pile foundation is transmission line construction, it not only can give full play to the advantage of undisturbed soil, improves the load-carrying properties on basis, but also eliminate the operation of underground formwork and pit backfill, the corresponding efficiency that improve construction; At present, the method for hand excavation's foundation ditch is all adopted traditionally, namely first by manually stake holes being dug, corresponding reinforcing cage is placed again in hole, and concrete perfusion forms pile-type, find in prolonged application, hand excavated pile has following defect: the lower operating condition in hole is poor, bad environments, safety is poor, and construction period is longer, and constructor operating space is limited, labour intensity is large, easily casualty accident occurs.
[summary of the invention]
In order to overcome the deficiency in background technology, the invention discloses a kind of transmission line foundation to draw and scrape out hole construction method, described method not only effectively can evade the security risk of artificial lower hole operation, but also effectively can shorten construction period, improves integral construction efficiency.
For achieving the above object, the present invention adopts following technical scheme:
A kind of transmission line foundation is drawn and is scraped out hole construction method, described method implementing procedure is as follows: Ground arrangement → assembly and adjustment → rig adjustment → straight hole creeps into → expands end operation → quality examination → transfer hole position → foundation ditch and completes → shift place, and its particular content is:
One, Ground arrangement: to open according to job site operating condition, basic root, the factor such as drill configuration size, rig approach course, concrete construction flow process, carry out rig operating position, dregs is stacked, cage of reinforcement is processed and the design of placing of material position, require spot plane connection and reasonable arrangement, guarantee smooth implementation and operation;
Two, assembly and adjustment: rig is transported to place, utilizes drilling machine mast straight hole drill bit and bottom expanding drill to be moved to need that to draw the foundation ditch dug near coal-mine, requires that the size of straight hole drill bit and the diameter-enlarging drill bit be equipped with can meet foundation ditch aperture, hole depth and expanding requirement; First straight hole drill bit is installed, makes the pin-and-hole bottom the corresponding drilling rod of straight hole drill bit, then insert pin by straight hole drill bit and drilling rod locking, require to guarantee that each system of rig all can normally work simultaneously;
Three, rig adjustment: excavate out the foundation ditch open test pit of the 200mm degree of depth according to design aperture by artificial, and repetition measurement root is opened, diagonal and aperture size, and driller insertion is operated after condition meets designing requirement;
Four, straight hole creeps into: after driller insertion centering, starts drilling construction, requires that rig zero load runs up, and starts to creep into hourly velocity and wants, slowly to protect near coal-mine shape, when drilling depth reaches a drilling bucket height, to revolve according to the corresponding quickening of actual soil property situation the speed of digging;
Five, end operation is expanded: when after excavation of foundation pit to design hole depth, be diameter-enlarging drill bit by straight hole bit change-over, carry out at the bottom of expansion; After foundation ditch is drawn and scraped out hole, use laser measuring apparatus to carry out total quality inspection to foundation ditch, require that laser measurement instrument probe possesses illumination and shoot function, measurement result and one-tenth hole shape directly can be transferred to chart display and show line item of going forward side by side;
Six, shift position, hole: when first foundation ditch draw dug and by quality examination after, rig moves to next Foundation Pit position according to mobile alignment planned in advance, and the verticality of borer drill rod is checked again, repeat the excavation operation that above-mentioned steps carries out next foundation ditch after meeting the requirements; Require that rig crawler belt and near coal-mine edge when mobile keep the spacing of more than 1.5m;
Seven, shift place: after all foundation ditches are all drawn and dug in basis, will draw and dig rig and ancillary service is transferred to next construction plant, and before requiring to shift place, air ferry route should be planned in advance;
Further, in work flow at the bottom of described expansion, the all controls of laser measuring apparatus in measuring process all pass through conputer controlled, and laser measuring apparatus supporting have can launch infrared rays by infrared camera and receive reverberation to calculate diameter and the degree of depth of foundation ditch pore-forming, possess illumination and the laser range finder of shoot function simultaneously.
Further, in described transfer place flow process, when being shifted by highway, should trailer transportation being taked, when not possessing the condition of trailer transportation, requiring below crawler belt, to lay straw mattress or take other can avoid damaging by pressure the safeguard procedures of highway.
Owing to adopting technical scheme as above, the present invention has following beneficial effect:
Transmission line foundation of the present invention is drawn and is scraped out hole construction method and be applicable to geological conditions is common soil, hard soil, groundwater level depth are greater than embedded depth of foundation foundation ditch and draw and dig operation; Compared with digging with traditional manually drawing, described method apply time not only place take little, orographic condition requires low, environment pollution can be reduced, reduce construction cost, accelerating construction progress, effective raising efficiency of construction and shortening construction period, and its hole quality is better, hole wall finishing process amount is less, the security risk of artificial lower hole operation can be evaded, thus reach and effectively reduce project management department's construction organization pressure, for digging foundation widelys popularize the object creating better condition in transmission line construction from now on.
[detailed description of the invention]
Can explain the present invention in more detail by the following examples, disclose object of the present invention and be intended to protect all changes and improvements in the scope of the invention, the present invention is not limited to the following examples:
Described transmission line foundation is drawn and is scraped out hole construction method, described method implementing procedure is as follows: Ground arrangement → assembly and adjustment → rig adjustment → straight hole creeps into → expands end operation → quality examination → transfer hole position → foundation ditch and completes → shift place, and its particular content is:
One, Ground arrangement: to open according to job site operating condition, basic root, the factor such as drill configuration size, rig approach course, concrete construction flow process, carry out rig operating position, dregs is stacked, cage of reinforcement is processed and the design of placing of material position, require spot plane connection and reasonable arrangement, guarantee smooth implementation and operation;
Two, assembly and adjustment: rig is transported to place, utilizes drilling machine mast straight hole drill bit and bottom expanding drill to be moved to need that to draw the foundation ditch dug near coal-mine, requires that the size of straight hole drill bit and the diameter-enlarging drill bit be equipped with can meet foundation ditch aperture, hole depth and expanding requirement; First straight hole drill bit is installed, makes the pin-and-hole bottom the corresponding drilling rod of straight hole drill bit, then insert pin by straight hole drill bit and drilling rod locking, require to guarantee that each system of rig all can normally work simultaneously;
