Description
Technical field
The invention belongs to sewage conduct technical field of construction, more particularly to a kind of municipal blow-off line laying construction method.
Background technology
At present, municipal blow-off line is generally laid by the way of zonal cooling construction, and each section using following
Construction technological process：
S1, digging groove, form foundation trench；
S2, installation foundation trench supporting construction, generally use steel plate box supporting, the purpose is to：On the one hand it is the peace for ensureing foundation trench
Entirely, the security of operation in workmen's subsequent pit is on the other hand improved；
S3, to the bottom of foundation trench ttom of pipe concrete is poured, one of polyethylene expansion joint plate, stretched polyethylene are set every 6 meters
Contracting seam plate is fixed by specialized structure, and the ttom of pipe concrete to pouring is by manually carrying out leveling；
After the tentatively solidification of S4, the ttom of pipe concrete after pouring, the time generally tentatively solidified is 4-8 hours, by rising
Hang equipment one or more pipe is placed on the ttom of pipe concrete after solidification, and pipe is fixed on by ttom of pipe by iron wire and mixed
On solidifying soil, when can so avoid follow-up concreting, pipe floats；
S5, the linearity for adjusting pipe, can use wedge-shaped concrete block or larger stone；
S6, pipe shaft, tube top concrete are poured, the surrounding up and down of pipe is wrapped by concrete；
S7, backfill groove, so far complete the construction of one section of sewage conduct.
In above-mentioned construction technological process, when carrying out the artificial equating of the 3rd work step, the blow-off line of the 4th work step of progress
When fixed and when carrying out the pipe straightening of the 5th work step, it is required to workmen and enters progress in groove, workmen is in ditch
Time in groove is longer, on the one hand causes construction period longer, and another aspect operation is dangerous big, and it is hidden to there is more safety
Suffer from, such as, when the both sides not support template of groove or when supporting is not in place, it there is the hidden danger of groove landslide.In addition, it is necessary to
Carry out concrete twice to pour, the hardening time of provided pipe base concrete is wanted in centre, so, causes that the engineering time is longer, apply
Work efficiency rate is low.
The content of the invention
The present invention for solve known technology present in technical problem provide a kind of simplified process, shortening the construction period,
Be used in turn rate, raising working security and the guarantee for accelerating efficiency of construction, reduction material cost, raising foundation trench supporting construction are applied
The municipal blow-off line laying construction method of working medium amount.
The present invention is adopted the technical scheme that to solve technical problem present in known technology：
Municipal blow-off line laying construction method, the construction method are laid by the way of zonal cooling construction, its
It is characterised by：Prefabricated in advance lower concrete cushion block and and lower concrete are employed in each section of process of deployment
Top concrete briquetting that cushion block is engaged, in the upper surface medium position and top concrete briquetting of lower concrete cushion block
The medium position of lower surface is respectively equipped with the semi-circular recesses to match with the external diameter of sewage conduct to be laid, and two halves circle is recessed
Groove can be spliced into a full circle positioning through hole；Each section of process of deployment comprises the following steps successively：
Poured on S1, ground at the construction field (site), prefabricated polylith lower concrete cushion block and polylith top concrete briquetting；
S2, digging groove, form foundation trench；
S3, installation foundation trench supporting construction；
S4, by lifting appliance and human assistance by prefabricated polylith lower concrete cushion block, one or more pipe
And prefabricated polylith top concrete briquetting is successively placed in foundation trench, one piece of top concrete briquetting and one piece of bottom coagulation
Native cushion block forms combining structure up and down, the both ends of every pipe is respectively supported at the semicircle recessed of one piece of lower concrete cushion block
In groove, and it is pressed in respectively in the semi-circular recesses of one piece of top concrete briquetting；And in two groups of adjacent lower concretes
Polyethylene expansion joint plate is directly placed between the combining structure of cushion block and top concrete briquetting；
S5, pipe external wrapping concrete, the top surface of concreting to top concrete briquetting are poured into foundation trench；
S6, backfill groove, so far complete the laying of one section of sewage conduct.
The technical scheme that the present invention can also take is：
The caliber of used pipe is D, and the length of every pipe is 6 meters, the height of every piece of lower concrete cushion block and every
The height of block top concrete briquetting takes δ, then δ=D/2+300mm, the width of every piece of lower concrete cushion block and every piece of top
The width of concrete blocks takes L1, then L1=D+600mm, the length and every piece of top concrete of every piece of lower concrete cushion block
The length of briquetting takes L2, then L2 >=1m.
The top concrete briquetting at every pipe both ends and the prefabricated dosage of lower concrete cushion block are every with corresponding in S5
The proportionate relationship of the amount of pouring of the concrete of root pipe is 33:67.
The present invention has the advantages and positive effects of：
1st, each section of construction shorten to six procedures by existing seven procedure, and concrete is poured by subtracting twice
It is few to arrive once, so, the preliminary setting time of centre is eliminated, ensure that construction is carried out continuously, so as to improve efficiency of construction
With shorten the construction time, improve 60% or so through preresearch estimates efficiency, the duration reduces 60% or so.
2nd, using the combining structure of cushion block and briquetting, amount of concrete 33% is to pour on the ground corresponding to every pipe
Build, be prefabricated, so improving security and efficiency simultaneously, security improves 33% or so, on the ground with the efficiency comparison of underground
Improve 50% or so.
3rd, using this construction method, it is not necessary to carry out in foundation trench artificial levelling and pipe is fixed with iron wire, this
Sample, activity duration of the people in foundation trench is drastically reduce the area, improve the security of construction and ensure that personal safety.
4th, pipe need not be fixed with iron wire in this construction technology, so reduces the dosage of material, reduce
Material cost.
5th, foundation trench generally use steel plate box supporting, using existing construction method, every piece of steel plate box at least needs 2 day time
It can down have enough to meet the need, and use this construction method, every piece of steel plate box only needs 1 day time down to have enough to meet the need, circulation material utilization rate
50% is improved, benefit accordingly improves.
6th, place polyethylene expansion joint plate needs specially to be fixed in existing construction method, and uses this construction party
Method, polyethylene expansion joint plate are directly sandwiched between adjacent cushion block and the combining structure of briquetting, so, avoid the need for setting specially
The fixed structure of door, this improves efficiency and the security of operation.
