Abstract
The invention discloses a construction method for carrying out rolling compaction and slope reinforcement on a faced dam. The method comprises the following steps: before construction, installing and fixing a first-floor template, then carrying out rolling compaction on a bedding material, and embedding tie bars into the bedding material; after the first floor is subject to rolling compaction to be qualified, utilizing a mechanical lifting template 5CM to carry out mortar pouring; after the mortar strength is allowed, arranging a lifting trolley on an end template, installing a second-floor template for carrying out rolling compaction, and utilizing a trolley lifting template to carry out mortar pouring after the second floor is subject to rolling compaction to be qualified; in the process of constructing a third floor, arranging a rack track capable of moving up and down on two templates at the end, moving the trolley to the orbital position, utilizing a jack to jack up the trolley, then rotating a running gear for 90 degrees, and placing onto the track, thus enabling the trolley to run to a track on the second-floor template to operate; and utilizing the trolley to lift the constructed first-floor template for a certain height, translating to the third floor, installing into a proper position, carrying out rolling compaction, and repeating the operation in this way until finishing the construction. The construction method has the advantages of little interference to the site and rapid construction progress.
Description
Technical field
The present invention relates to a kind of solid sloping job practices, relate in particular to a kind of face dam and roll solid sloping job practices.
Background technology
Concrete panel rock fill dam bedding material up stream slope surface construction, adopt the slope to roll solid sloping method both at home and abroad: when bedding material fills always, upstream about face extra-fill 30CM, before the panel construction, repair the slope, roll on the slope, the mortar that manually paves on the slope rolls on the slope again.Its shortcoming is that to repair sloping engineering quantity big, and slope grinding compacting degree is difficult to guarantee, and is big with the design lines deviation, causes the panel concrete extra-fill; Repairing the transportation of slope material and abandoning material all can increase engineering cost, and the on-the-spot interference of simultaneously this job practices is big, and construction speed is slow.
Summary of the invention
Purpose of the present invention just is to provide a kind of on-the-spot interference little, the solid sloping job practices of face dam that construction speed is fast.
To achieve these goals, the technical solution used in the present invention is such: the solid sloping work progress of face dam of the present invention is:
Carry out first floor template earlier before a, the construction and install and fix, and then carry out the bedding material roller compaction construction, and in bedding material, imbed lacing wire;
B, first floor roll qualified back and build mortar with on-the-spot mechanical lifting template 5CM;
C, the chassis for the treatment of will hoist after mortar strength allows are installed on the template of termination, and utilize chassis that second layer template is installed and roll, and carry out mortar with the chassis climbing shuttering again after qualified to build;
D, when carrying out tri-level construction, chassis is moved to an end, on two templates in termination, the rack-track that moves up and down is arranged, chassis is moved on to orbital position, jack-uping behind the chassis is put on the rack-track that moves up and down after will running gear rotating 90 degree, and chassis can be walked and be carried out work on the left and right directions track of second layer template;
E, the first floor template of utilizing chassis that construction is finished promote and move to the 3rd layer of installation in position behind the certain altitude and install, and carry out roller compaction construction again, and circulation is finished dam facing and rolled Gu Po so repeatedly.
Compared with prior art, the invention has the advantages that: 1. formwork support arrangement precision height, distortion is little in the construction, guaranteed construction precision and construction quality, the constraint of counter plate can adapt to dam deformation preferably less than the construction of squash type abutment wall, help the panel anticracking, the construction surfacing does not have faulting of slab ends.2. speed of application is fast, has cancelled traditional extra-fill, cuts the slope and repaiies the slope, operation such as rolls, and adopts mechanical chassis to carry out formwork and has saved the time.3. construction cost reduces, and has reduced extra-fill and has cut slope and slope rolling apparatus, has reduced the extra-fill concrete, has comprehensively saved cost more greatly.4. safety is good, and construction technology is simple, and construction is disturbed little, helps safe construction, fills that dam body promptly possesses the dash condition in the process, has improved the degree of safety of dam construction phase.5. be applicable to various face dams, template also can be used for the casting of concrete in mass construction.
The specific embodiment
Below the present invention is described in further detail.
Face dam of the present invention rolls the work progress of Gu Po: earlier the domatic first floor template of carrying out installs and fixes in the upstream before the construction, treat that template installs after, carry out the bedding material roller compaction construction again, and in bedding material, imbed lacing wire; The designing requirement that bedding material will satisfy: require the bedding material maximum particle diameter can not be too big, should contain more fines; Semi-transparent water-based, low compressibility and high shear strength are arranged; Bedding material is the good limestone artificial preparation material of aplastic grating, requires particle hard, durable, no clay and organic impurities; The grading limit of bedding material is: maximum particle diameter 80MM, and containing the gravel amount is 45%～65%, should be continuous grading; Plain asphalt is chosen with reference to the relevant technologies index of the SYI1665/77 trade mark 65 in the plain asphalt sand compound; Roll bed thickness 40CM, the watering amount is 10%.First floor rolls qualified back and builds mortar with on-the-spot mechanical lifting template 5CM; The chassis for the treatment of will hoist after mortar strength allows is installed on the template of termination, and utilizes chassis that second layer template is installed and roll, and carries out mortar with the chassis climbing shuttering again after qualified to build; When carrying out tri-level construction, chassis is moved to an end, on two templates in termination, the rack-track that moves up and down is arranged, chassis is moved on to orbital position, jack-uping behind the chassis is put on the rack-track that moves up and down after will running gear rotating 90 degree, and chassis can be walked and be carried out work on the left and right directions track of second layer template; The first floor template of utilizing chassis that construction is finished promotes and moves to the 3rd layer of installation in position behind the certain altitude and install, and carries out roller compaction construction again, and circulation is finished dam facing and rolled Gu Po so repeatedly.
All adopt Bolt Connection between the template, all have on every template can move left and right rack-track, for hoisting trolley running.
The speed of application of this job practices is fast, has cancelled traditional extra-fill, cuts the slope and repaiies the slope, operation such as rolls, and adopts mechanical chassis to carry out formwork and has saved the time; Construction cost reduces, and has reduced extra-fill and has cut slope and slope rolling apparatus, has reduced the extra-fill concrete, has comprehensively saved cost more greatly; Safety is good, and construction technology is simple, and construction is disturbed little, helps safe construction, fills that dam body promptly possesses the dash condition in the process, has improved the degree of safety of dam construction phase; Be applicable to various face dams, template also can be used for the casting of concrete in mass construction.
