Abstract
The present invention relates to a construction method for a herringbone retaining wall. Prefabricated parts of the herringbone retaining wall are arranged in design positions according to design requirements. Firstly, foundations are smoothed, drainage pipes are arranged, the foundations are tamped with pebbles to form a pebble basal layer, a cement sand layer or a concrete layer is arranged on the pebble basal layer, a patter setting datum line (a straight line or an arc line) is arranged on the cement sand layer or the concrete layer, the retaining wall is hoisted and arranged, and the wall back is filled with pebbles and a soil layer. The present invention has the advantages of reasonable design and convenient construction. The construction method is suitable for hillsides, roads, water channels, etc. and has a stable structure with larger soil pressure resistance and water pressure resistance.
Description
The present invention relates to slope protection works, further is the retaining wall engineering.
Present China rapid economic development; various civil engineerings emerge in an endless stream like rain the back spring bamboo; therefore for the safety of protecting major project and the natural, ecological of protecting surrounding environment; particularly for railway, highway engineering; mine development; the stable slope protection works with natural environment in necessary maintenance hillside has more appearred in the industry of rivers and creeks bank protection and knob and civilian construction.Existing slope protection works roughly has following several processing method:
1, adopt the nature bank protection, this kind mode not only ground works is big, and takies a large amount of soils, does not obviously conform with modern requirement.
2, grout cobble or pitched work, this method is applicable to the preferably little engineering of geological condition, and is relatively poor for large-engineering or geological condition, because of building stones collection and transportation difficulty, and inapplicable.
3, gravity concrete retaining wall, normal palpus in-site pouring concrete, and relatively poor to the strain capacity of soil pressure and water pressure on mechanics.
4, font of falling T or L font retaining wall are present widely used methods, but consider that from the mechanics angle soil pressure that its upstanding wall can bear is still undesirable.
The present invention is directed to above-mentioned situation and propose a kind of job practices of herringbone retaining wall, its purpose is to provide a kind of easy construction, the retaining wall job practices that is applicable to various landform that cost is low; Another object of the present invention provides a kind of relative T font and L font retaining wall, has the retaining wall job practices of better mechanical property.
Technical scheme of the present invention (can concentrate on prefabrication and transport to the job location for using a kind of herringbone retaining wall prefabricated component, also can be prefabricated at the scene the back for construction with) install by engine request, and before construction, fix a drainpipe and carry out Foundation Design.
Details are as follows in conjunction with the accompanying drawings in the present invention, wherein:
Fig. 1 is a herringbone retaining wall engineering schematic perspective view;
Fig. 2 is herringbone retaining wall construction schematic cross-section;
Fig. 3 is herringbone retaining wall stress distribution and physical dimension schematic diagram;
Fig. 4 is the herringbone retaining wall schematic diagram that is used for road;
Fig. 5 is the herringbone retaining wall schematic diagram that is used for stablizing the hillside;
Fig. 6 is the herringbone retaining wall schematic diagram that is used for the water route.
As shown in Figure 2, ground is at first put at the place in order at the installation retaining wall, if then must on the layer eliminating phreatic gutter (2) be set forever thoroughly when underground water is arranged, ram with cobble then and fill out basic boulder bed (3), (5), the surface configuration of this basis boulder bed should match with the bottom shape of herringbone retaining wall (8), establishes the thick cement sand bed of 3-4cm or base concrete layer (4) and (6) again on basic boulder bed.The rule directrix (straight line or camber line) that the retaining wall sole is drawn in designing requirement is pressed on its surface again after cement mortar or concrete setting, again prefabricated retaining wall is sling, make on its rule directrix that fitly is arranged in setting in placely, and fix with cement mortar at the joint of two barricades.After cobble (7) was filled up at herringbone retaining wall (8) back, banket (1) made it to become a complete slight slope again at last.
The architectural feature of herringbone retaining wall of the present invention is made up of a stalk and former and later two soles as shown in Figure 3, and sole (being the right crus of diaphragm plate among Fig. 3) is greater than forefoot plate thereafter, if having set the height of retaining wall is h, then sole length is 0.40725h thereafter, forefoot plate is 0.375h, and stalk end thickness is 2 * 0.025h (the strong wall dotted line on one's body of retaining soil is represented spilled water hole among Fig. 3).
Herringbone retaining wall of the present invention is applicable to various landform and different purposes, and following embodiment is illustrated respectively.
Embodiment 1, and to be applied to geological conditions relatively poor when retaining wall, during domatic higher location, can vertically arrange three gear cob walls as shown in Figure 1 continuously, also can be more when needing.
Embodiment 4, and Fig. 6 represents that herringbone retaining wall of the present invention is applied to water channel, and the construction section of water channel etc. is arranged.
Embodiment 5, Fig. 3 represents the appearance and size of retaining wall of the present invention and the situation of drag, and h represents the wall height among the figure, and 0.40725h is a back sole length, 0.375h be forefoot plate length, Wc is the deadweight of wall body, and Ww conducts oneself with dignity for the above soil body in basis within the walls, E be within the walls the side group plinth with pressure that upper part was born, P is making a concerted effort of Ww and E, δ=Φ=30 ° are angle of internal friction, ° the elevation angle, ψ=60 for the P that makes a concerted effort, and 0.241b is the arm of force of Ww.
Claims (2)
1, a kind of construction process of herringbone retaining wall, it comprises the steps:
A, arrangement ground, the cleaning basis;
B, at the default gutter of impervious layer;
C, rammer are filled out basic cobble, and the bottom of aspect and herringbone retaining wall is coincide;
D, on basic boulder bed, establish cement sand bed or layer of concrete;
E, after the rule directrix of the engineering of drawing by design on cement sand bed or the layer of concrete lifting retaining wall prefabricated component;
Fill boulder bed and soil layer behind f, the wall.
By the described construction process of herringbone retaining wall of claim 1, it is characterized in that 2, the overall dimensions of herringbone retaining wall are such, forefoot plate length is 0.375h, and back sole length is 0.40725h, and the wall tip thickness is 2 * 0.25h, and above-mentioned h is the wall height.
