Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a construction method for internal roads and garage ramps of a villa complex. Background Art

[0002] At present, many villa complexes, especially townhouse complexes, are built along the mountains and rivers, following the undulating terrain. Each villa has a different positive and negative zero elevation. However, in the process of road planning and design in the community, this terrain feature was not fully taken into account, resulting in the elevation of the road and the elevation of each villa not being scientifically and reasonably matched.

[0003] Specifically, due to the lack of accurate grasp and careful consideration of the terrain, the elevation of the internal road failed to form a smooth transition and connection with the elevation of the villa. This design defect directly led to the excessive slope of the underground garage ramp, which far exceeded the safe range for normal vehicle entry and exit. In actual use, many vehicles were unable to enter and exit the garage smoothly due to the steep slope, which not only brought great inconvenience to residents' daily travel, but also seriously affected the overall traffic fluency and safety of the community.

[0004] Therefore, in response to this problem, the present invention provides a construction method for internal roads and garage ramps of a villa complex. Summary of the invention

[0005] In view of the above-mentioned problems, the present invention discloses a construction method for internal roads and garage ramps of a villa complex, so as to solve the problem that the elevation of the internal roads of the villa complex fails to form a smooth transition and connection with the elevation of the villas, resulting in the slope of the underground garage ramp being too large and vehicles being unable to smoothly enter and exit the garage.

[0019] In some of the embodiments, during the two plastering construction processes:

[0020] The first plastering construction is carried out immediately after the concrete surface layer is leveled to remove the seepage water and press down the stones;

[0031] The present invention is further described below with reference to the accompanying drawings and specific embodiments, but is not intended to be a limitation of the present invention.

[0032] like Figure 1 As shown, the present invention discloses a construction method for internal roads and garage ramps of a villa complex. Specifically, the construction method comprises the following steps:

[0033] Step S1, measure the elevation of the garage floor of each villa, and adjust the garage ramp, road elevation (focus on adjusting the road elevation in front of the garage) and size according to the measured data, and judge whether the slope of the adjusted garage ramp meets the preset slope condition. The preset slope condition is that the slope is less than 17%. If it does not meet the preset slope condition, the road in front of the garage ramp is used for slope reduction. Specifically, in the process of using the road in front of the garage ramp for slope reduction, the width of the borrowed road 1 is 1m~1.5m, such as Figure 2 As shown; at the same time, the elevation of the road adjacent to borrowed road 1 is adjusted according to the positive and negative zero elevation of each villa, specifically to determine the longitudinal slope and slope length of the road to change the slope ( Figure 22 is the slope change line), in order to reduce the driving safety hazards caused by excessive slope changes, a smooth transition section is set between different slopes, such as the slope change line 2 (point), by adjusting the elevation and using a gradual change method, the bumpy feeling when the vehicle passes through is reduced and the driving comfort is improved; so that other roads and the borrowed roads are smoothly transitioned, and the slope of each villa garage ramp meets the requirements. The table after adjusting the data is as follows Figure 3 As shown, then draw the cross-section and plan views of the internal roads and garage ramps.

[0034] Step S2, re-survey the survey points, and after establishing a construction wire network on the internal road and garage ramp according to the cross-section diagram and the plan view, and arranging the leveling control points, lay out the center line of the road and garage ramp according to the construction wire network and the leveling control points, and set a center pile and a pair of side piles every 8 to 12 m (for example, 8 m, 9 m, 10 m or 12 m) longitudinally, and use a level to mark the fill and excavation elevation lines on the center pile and the side pile respectively, and set the elevation control points of the base surface every 8 to 12 m (for example, 8 m, 9 m, 10 m or 12 m) according to the longitudinal slope and the transverse slope.

[0035] Step S3 is to carry out earth excavation, and to construct an 18 cm thick graded crushed stone subbase on the internal road and garage ramp according to the fill and excavation elevation line and the elevation control points of the base surface, and then use a roller to compact it.

[0036] Step S4, continue the construction process of cement concrete surface layer; wherein, C25 commercial concrete is poured with a horizontal slope of 1.5%; after concrete vibration and leveling, two surface finishing constructions are carried out, and after two surface finishing constructions, groove drawing operation (grooving in the horizontal direction) is carried out to form multiple grooves of a certain depth and width on the cement concrete surface layer, so as to improve the anti-skid performance of the road surface, improve the drainage performance, reduce noise, and extend the service life. The groove depth of the cement concrete surface layer is 2~4mm, the width is 3~5mm, and the spacing between adjacent grooves is 15~25mm. Specifically, the construction process of the cement concrete surface layer is carried out using a steel-wood composite formwork, which is made of channel steel and wooden formwork, and the arc of the steel-wood composite formwork adopts a wooden formwork; the thickness of the cement concrete surface layer is 18~22cm.

[0037] During the two-time plastering construction process: the first plastering construction is carried out immediately after the concrete surface layer is leveled, to remove the seepage water and press down the stones; the second plastering construction must be carried out when the concrete seepage water is in the initial setting state but the surface is still moist.

[0038] Step S5, curing the cement concrete surface layer; and the curing time of the cement concrete surface layer is 14 to 21 days.

[0039] Step S6, forming longitudinal joints, contraction joints and expansion joints on the surface of the cement concrete surface layer, wherein the contraction joint is 10 mm wide and is sawed every 4 m; the expansion joint is 20 mm wide and is set every 32 m, and asphalt is applied in the longitudinal joint, and asphalt sand is filled in the contraction joint and expansion joint.
