Referring to fig. 1-2, a preferred embodiment of the present invention is shown.
The side slope stabilizing structure of the open cut trench comprises a trench 100 which is formed in soil body and the top of which is opened to form an opening at the top, wherein a pipeline can be placed in the trench 100, and after the trench 100 is filled with the soil body, the laying of the pipeline is realized. Both sides of the groove 100 are formed with slopes, and the slopes are inclined toward the inside of the groove 100 in a top-down direction, so that the groove 100 is formed in a shape having a large top and a small bottom.
The two sides of the groove 100 are provided with external soil bodies 101, the top of the external soil body 101 is provided with a drainage ditch 200, and the drainage ditch 200 is arranged side by side with the groove 100 and is isolated from the groove 100; the outer soil body 101 is provided with a dewatering well, the bottom of the dewatering well is deeper than the bottom of the trench 100, and the dewatering well is arranged outside the drainage ditch 200.
According to the slope stabilizing structure of the open trench provided by the utility model, the drainage ditch 200 is arranged at the top of the soil body on the outer side, so that water on the soil body on the outer side can be guided out through the drainage ditch 200, the water on the soil body on the outer side is prevented from flowing down along the slope, the water is prevented from washing the slope, and the stability of the slope is ensured; secondly, by providing a precipitation well, groundwater around or below the trench 100 can be pumped out, thereby protecting the stability of the trench 100.
The top of the trench 100 is spaced apart from the top of the drainage ditch 200 by a separation dam 102, and the separation dam 102 extends along the length of the trench 100. In this way, water in the drainage ditch 200 is prevented from laterally falling into the trench 100, and the water can be completely isolated by the isolation dam 102.
The top of the isolation dam 102 is protruded upward with a boss 103, the boss 103 is extended along the length direction of the isolation dam 102, and the isolation between the trench 100 and the drainage ditch 200 can be enhanced by providing the boss 103.
The slope covers has geotechnological cloth, and the lower extreme of geotechnological cloth extends to the bottom of slope, and boss 103 is crossed to the upper end of geotechnological cloth, extends to the side of slot 100, and geotechnological cloth has covered boss 103. The arrangement of the geotextile can isolate water from directly scouring the side slope and can avoid water from permeating into the side slope.
The slope is provided with a plurality of step surfaces 301 arranged upwards, the step surfaces 301 extend along the length direction of the groove 100, and the step surfaces 301 are sequentially arranged at intervals along the inclination direction of the slope. Like this, through setting up a plurality of step surfaces 301, even there is water to flow down along the side slope, a plurality of step surfaces 301 can play the effect of buffering, avoid the direct washing away of water to the side slope.
The width of the step surface 301 gradually increases along the slope direction from top to bottom of the slope. In this way, the speed of the water can be gradually buffered.
Along the extension direction of the slope towards the inside of the trench 100, the step surface 301 is arranged obliquely upwards, so that the water flowing over the step surface 301 is further buffered by the transition buffer of the oblique step surface 301.
The step surface 301 has an outer side portion facing an outer soil body and an inner side section facing the trench 100, the outer side section is recessed to form a buffer groove 302, and the buffer groove 302 extends in the length direction of the trench 100. The water falling on the step surface 301, the inclined arrangement of the step surface 301, can be buffered in a first step, and part of the water is temporarily stored in the buffer tank 302, so that the speed of the water can be further reduced.
The drainage ditch 200 has an inner side wall 203 formed at a side of the partition dam 102 and an outer side wall 202 disposed opposite to the inner side wall 203 and offset from the partition dam 102, and a drainage notch 201 is provided at a top of the outer side wall 202 of the drainage ditch 200. Thus, when the water level of the drainage ditch 200 is high, in order to prevent the water in the drainage ditch 200 from overflowing into the gutter 100, the water at the top of the drainage ditch 200 may flow out of the gutter 100 through the drainage notches 201.
The top of the inner sidewall 203 of the drain 200 is higher than the top of the outer sidewall 202 of the drain 200 so that the inner sidewall 203 of the drain 200 also forms a barrier that, in conjunction with the isolation dam 102 and the boss 103, forms a three-layer barrier to water outside the gutter 100.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
