Description
Technical field
The present invention relates to construction engineering technical field, more particularly, relate to and a kind ofly on super large breaks cross-section slope, carry out construction method that cement mortar bedding cushion builds and structure, belong to the pouring technique for the large-area retaining wall bed course of heavy grade.
Background technology
At present, in the basement construction of common buildings, special in the construction of deep foundation ditch, in order to ensure that the design of deep foundation pit degree of depth meets the demands, usually side slope is adopted multi level slope, but when the restriction of place red line and scene reality does not allow multi level slope, that slope retaining can be done is very steep very high, and the highest meeting reaches more than 10 meters.Because cement mortar is a kind of plastic material, mobility is comparatively large, when carrying out large slope cushion layer and building, cement mortar easily glides, particularly in the construction of comparatively steep higher slope, the thickness of bed course very easily produces the phenomenon of upper-thin-lower-thick, does not meet the construction quality requirement of waterproofing.Therefore, build principle based on what jump storehouse method, pass through technological innovation, propose a kind of easy and extremely easy-operating construction technology, solve by cement isogel material early flow large, difficult problem of evenly building on large slope, its construction quality is easy to control, good in economic efficiency.
Summary of the invention
Technical purpose of the present invention is intended to overcome the deficiencies in the prior art, there is provided a kind of to break the construction method of cross-section slope cushion layer and structure for super large, in the construction of high and steep big cross section slope waterproof bed course, it is unfavorable that the early flow controlling the cementitious material such as cement very well brings, and ensure that the construction quality of cement mortar bedding cushion.
Technical purpose of the present invention is achieved by following technical proposals:
A kind of construction method of cross-section slope cushion layer of breaking for super large, first on construction slope body 1, utilizing horizontal direction to draw draws every structure 6 every structure 5 and vertical direction, be divided into several build unit 4 by domatic for whole construction, wherein draw every structure 6 being evenly provided with vertical direction on Po Ding (or at the bottom of slope) direction, comprise vertical positioning bar 6-1, vertical spacing muscle 6-2, vertical formwork 6-3; Draw every structure 5 being provided with horizontal direction on construction slope body bevel direction, comprise horizontal shuttering 5-1, horizontal support muscle 5-2.
Carry out according to following step
Step (1) is according to the side slope situation of engineering reality, arrange vertical positioning bar, according to from slope, the chamfer length pushed up at the bottom of slope is uniformly distributed the vertical positioning bar of first row, then adopt the interval of each vertical positioning bar in same intervals and the vertical positioning bar of first row according to the length on (or top, slope) at the bottom of slope, body inclined-plane, slope arranges the vertical positioning bar of other all row.
When Specific construction, draw from side slope top along the vertical vertical direction in slope with tape measure bottom side slope, at interval, every 2000mm inserts a positioning bar, is knocked in the soil of slope body with hand hammer, lays out the vertical positioning bar of row; Then use tape measure stretching at slope bottom level, at interval, a positioning bar is inserted in the position of every 2200mm, and mark goes out the horizontal level of the positioning bar of other row, adopts the method same with the vertical positioning bar of first row, lays out other and arrange vertical positioning bar.Described vertical positioning bar selects diameter to be 6mm, and long is 200mm, and be placed in soil 100mm, material is HPB235.
Step (2), after vertical positioning bar has all been arranged, carry out layout vertical spacing muscle, one group of vertical spacing muscle is arranged respectively at 100-150mm place, the left and right sides of the vertical positioning bar often arranged, described vertical spacing muscle pushes up on the chamfer length direction at the bottom of slope on slope and is uniformly distributed, so, form two row vertical spacing muscle in the both sides of the vertical positioning bar of row, each row vertical spacing muscle is made up of on chamfer length direction is pushed up at the bottom of slope on slope some groups of vertical spacing muscle.
