A road construction technique

Abstract

The invention discloses a road construction technology, which solves the problem of uneven settlement in the central area and both sides of the road. The main point of the technical solution is a road construction process, which includes the following steps: S1, excavating the first foundation pit; S2, setting the reinforcement structure of the first foundation pit; S21, setting out the pile position of the first cement mixing pile; S22, according to Set out the first cement mixing pile at the pile position stakeout point; S23. Before the first cement mixing pile is solidified, excavate multiple transverse grooves at least one group of first cement mixing piles longitudinally, and there is at least one group of first cement mixing piles. The pile is located in the transverse groove; S24, laying the first reinforcement in the transverse groove, the first reinforcement has a first reinforcement part; S25, filling and compacting the transverse groove with undisturbed soil; S3, laying the first light quality soil layer; S4, laying the first stable layer; S5, laying the first surface layer; the central area and both side areas of the road manufactured according to the above-mentioned road construction process are not prone to uneven settlement.

Description

technical field [0001] The invention relates to a road construction technology. Background technique [0002] With the development of cities, the coverage of urban roads to cities is gradually increasing, and road construction is an indispensable part of urban construction. Authorized announcement number is that the Chinese utility model patent of CN203684254U discloses a kind of cement-soil mixing pile composite foundation, comprises road base, cushion course and cement mixing pile. The above-mentioned existing technical solution has the following defects: although the cement mixing pile can weaken the degree of uneven settlement of the above-mentioned composite foundation, after the above-mentioned road surface is put into use, the vehicle basically drives in the central area of ​​the road, so that the settlement of the central area of ​​the road needs to be It is obviously stronger than the areas on both sides of the road. As the road is put into use, the road surface wi...

Problems solved by technology

The above-mentioned existing technical solution has the following defects: although the cement mixing pile can weaken the degree of uneven settlement of the above-mentioned composite foundation, after the above-mentioned road surface is put into use, the vehicle basically drives in the central area of ​​the road, so that the settlement of the central area of ​​the road needs to be It is obviously stronger than the areas on both sides of the road. With the increase of the time the road is put into use, the road surface will have different degrees of bulges or depressions. In severe cases, longitudinal cracks will appear on the road surface. Road Construction Technology with Uneven Settlement in the Areas on Both Sides of the Road and in the Center Area
