Abstract
The invention relates to the constructional engineering technology, in particular to a slotted irrigation soil covering earth roadbed impact processing water supplement method, and the method is characterized in that: firstly, water ditches with the width of 1.2m and the depth of 0.80m are dig at intervals of 5m along the direction vertical to a roadbed, the dig earthwork is placed between two ditches, water is injected to the water ditches from one end of each of the water ditches until the water ditches are filled with water, soil layers are soaked, and the water ditches are filled after the water permeates completely; and then a water ditch with the width of 1.2m and the depth of 0.5m is dig between every two filled water ditches, then water is injected to the ditches to soak, after the water permeates completely, the ditches are filled, water is sprinkled and soil is covered on the surface of the roadbed at night; and the method has simple and convenient operation and high mechanization degree, does not need line-putting ditch by ditch, the water supplement is uniform, the soil is humidified completely, the effect is rather ideal, and the method is mainly applicable to roadbed impact processing water supplement construction in northwest arid areas.
Description
The ㈠ technical field: the present invention relates to architectural engineering technology, especially a kind of slotted irrigation soil covering collapsible earth roadbed impact is handled method for supplementing water.
The ㈡ background technology: in the highway construction project construction, common collapsible soil roadbed processing method has multiple, adopts impact road roller shock treatment work efficiency height, and is economical and practical, is a kind of novel process technology that occurs in recent years.Must replenish moisture content to foundation soil before the shock treatment, sprinkle water the in advance method of the vexed soil or the water filling of digging pit of general employing, it is fully moistening to make the roadbed collapsible soil handle the interior soil of depth bounds (the general following 120cm in the face of land is dark), and shock treatment just can obtain optimum efficiency.Adopt the method for the vexed soil of surface watering simple to operate, top layer moisturizing effect is obvious, but-the following soil layer moisturizing of 50cm poor effect; The dig pit method of moisturizing of employing is to keep at a certain distance away to adopt artificial or mechanical equivalent of light excavation quincuncial arrangement heatable adobe sleeping platform, water filling is soaked in heatable adobe sleeping platform, the method moisturizing needs to combine with the top layer vexed soil phase of sprinkling water, the moisturizing effect than the watering of independent top layer better, but still not very good, and operation is complicated, needs by unwrapping wire location, hole, and need connect than long water pipe, water could be annotated in each hole.
The ㈢ summary of the invention: purpose of the present invention is exactly to solve the simple mode that adopts the vexed soil of surface watering, deep layer soil property moisturizing poor effect, though and the water flooding regime moisturizing effect of digging pit has improvement, but still it is undesirable, and operation is complicated, problems such as water filling inconvenience provide a kind of slotted irrigation soil covering collapsible earth roadbed impact to handle method for supplementing water.
Concrete scheme of the present invention is characterized in that: at first excavate wide 1.2m, dark 0.80m ditch along vertical roadbed direction by the 5m spacing, the earthwork of excavation is stored between two ditches, one end water filling in the ditch from the ditch, make water fill with the ditch, soak soil layer, treat after water has permeated the ditch to be filled and led up; Dig 1.2m, dark 0.5m ditch then in the middle of ditch that every twice are filled and led up, water filling is soaked in ditch again, fills and leads up the ditch after water has permeated, and evening is at the road bed vexed soil of sprinkling water.
The method that the present invention adopts ditching to combine with the top layer watering, but mechanized is easy and simple to handle, need be by the hole unwrapping wire, moisturizing is even, and is fully moistening, and the moisturizing effect is very good, can make the collapsible soil shock treatment obtain optimum efficiency.
The ㈣ description of drawings:
Fig. 1 is that secondary ditching roadbed of the present invention is partly led (cuing open) view;
Fig. 2 is a partly vertical view of secondary ditching roadbed of the present invention.
Among the figure: 1-roadbed ground, 2-deep water ditch, 3-shallow gully.
The ㈤ specific embodiment:
Adopt the inventive method to carry out impact processing water supplement in certain highway section, concrete operation method is: adopt excavator, at first excavate wide 1.2m, dark 0.80m deep water ditch 2 by the 5m spacing along vertical roadbed direction, the earthwork of excavation is stored between two ditches, from the water filling in deep water ditch 2 of deep water ditch 2 one ends, make water fill with deep water ditch 2, soak soil layer, treat after water has permeated the ditch to be filled and led up; Dig 1.2m, dark 0.5m shallow gully 3 then in the middle of ditch that every twice are filled and led up, water filling is soaked in shallow gully again, fills and leads up shallow gully after water has permeated, and evening is at the road bed vexed soil of sprinkling water.Combine with the top layer vexed soil phase of sprinkling water by twice ditching of the inventive method is soaked, can make the dark soil layer of roadbed 0～1.5m all obtain abundant moisturizing, can carry out shock treatment in second day.
