Description

Construction method for compacting periphery of asphalt pavement inspection well and transition well cover

Technical Field

The invention relates to the technical field of inspection well construction, in particular to a construction method for compacting the periphery of an asphalt pavement inspection well and a transition well cover.

Background

The compaction thickness of the asphalt surface layer refers to the actual thickness of the asphalt surface layer after rolling according to a construction scheme, the loose paving thickness is determined through a test section, and the paving thickness of the asphalt mixture can reach the designed thickness after compaction under the given construction conditions of the asphalt mixture, a rolling machine, a rolling method and the like. The loose paving thickness and the compaction thickness do not have an accurate and strict functional relationship, but are influenced by many factors such as the characteristics of the asphalt mixture, the construction temperature, the combination of compaction tools and machines, the compaction method, the compaction pass and the like, and a mathematical relationship is presented by a statistical rule. Therefore, only rough control of the compacted thickness is possible during the construction of the asphalt surface course, and it is difficult to strictly control the compacted thickness within a precise range.

The road roller has the following pushing effect: in the process of advancing or retreating the road roller, as the surface of the rolling wheel and the asphalt mixture have larger horizontal friction force, the asphalt mixture can be pushed to move in a wave shape along the running direction of the road roller, and the temporary well cover or the permanent well seat can be displaced or deformed by the horizontal load conducted by the asphalt mixture under the condition of not being fixed firmly. The effect is not controlled to be in place, and the problem of poor flatness around the inspection well is easily caused.

The problems of local protrusion, pits and the like of the asphalt surface layer around the inspection well are caused by the fixation of the height of the well cover in the rolling process and the dynamic and uncertain change of the thickness of the asphalt mixture. The problem is the flatness which is directly caused by the dynamic response among the road roller, the asphalt mixture and the well seat in the construction process and is directly displayed after the construction is finished, and the problem is called as the initial flatness problem.

In the operation process, the asphalt surface layer around the well is loosened, cracked and settled, so that the flatness of the asphalt surface layer around the well is reduced, the passing quality of vehicles is influenced, and the vehicles jump when passing. The problems are uneven settlement caused by insufficient compaction of asphalt surface layers around wells or insufficient compaction of base layers and subgrades in the range around wells, and are gradually developed in the operation period to cause unevenness and vehicle jumping around wells, so the problems are called as 'later-stage flatness problems'.

At present, the construction around the asphalt surface layer of the inspection well usually adopts a method of shielding the inspection well mouth by a transition cover plate, then paving the asphalt surface layer by layer, cutting off asphalt near the inspection well mouth, installing an inspection well seat and a well cover by taking the elevation of the asphalt surface layer as a basis, and finally paving an asphalt mixture manually to fill up the vacancy around the well seat.

The existing method has the following defects:

1. and the asphalt surface layer around the inspection well is cut off together after the two surface layers are paved. After the well base is installed, the surrounding gap is repaired and rolled layer by layer in an artificial material distribution mode. Because the elevation of the inspection well base is higher than that of the asphalt lower surface layer, a road roller at the axillary angle part around the well base cannot roll in place during the construction of the asphalt lower surface layer, so that the compactness of the asphalt lower surface layer at the position is insufficient, and the later-stage flatness problem is generated.

2. Because the range of the cut-off part is small, only a small-sized roller can be used for rolling. The tonnage of the rolling machine is light, the rolling wheel is partially rolled on the upper surface layer of the formed asphalt in a cross-joint manner, the rolling effective load is further reduced, the lack of compactness is easily caused, and the later-stage flatness problem is generated.

3. Similarly, because the range of the cut-off part is small, one part of the rolling wheel presses on the rigid formed asphalt upper surface layer and the other part presses on the flexible hot-mixed asphalt mixture during cross-seam rolling in the rolling process, and the rolling wheel can incline towards the flexible asphalt mixture under the action of gravity to form a local pit, so that the problem of initial flatness is generated.

4. The total amount, the uniformity and the paving flatness of the asphalt mixture are difficult to control by manual distribution, the flatness of an asphalt surface layer around a well seat is easily influenced, and the problem of initial flatness is generated.

5. The formed asphalt surface layer needs to be removed by milling by a milling machine, and the cost of a mechanical machine is high.

6. When the well seat is not firmly fixed, the transition phenomenon of the asphalt mixture around the well in the rolling process of the road roller interacts with the well seat, so that the asphalt mixture is easily accumulated locally, and a bulge or a pit is generated.

Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

Referring to fig. 1 to 4, according to an aspect of the present invention, there is provided a construction method for compacting the periphery of an asphalt pavement inspection well, including the steps of:

in step S1, the transition manhole cover 100 covers the inspection shaft 200.

Maintenance of the road base 300 is completed and cleaned, and after the kerbstone is built, the inspection shaft 200 is covered by the transition well cover 100 before the construction of the asphalt lower surface layer 400.

And step S2, paving and rolling the asphalt lower surface layer 400.

Step S3, taking out the transition manhole cover 100: and after the rolling of the asphalt lower surface layer 400 is finished, excavating asphalt mixture on the surface of the transition well lid 100 and in the peripheral range, and taking out the transition well lid 100.

The asphalt mixture above the transition well lid 100 and around needs to be removed after the asphalt lower surface layer 400 is rolled, local unevenness of the well mouth can be eliminated by the removing process in the construction process, and the flatness after forming is not affected. And after the asphalt lower surface layer 400 is rolled, the transition well lid 100 can dig out asphalt covering the transition well lid 100 and the periphery while the asphalt is hot, and the transition well lid 100 is turned to the front for continuous use. The transition well lid 100 has small usage amount once, can be recycled for a plurality of times in single construction, and has low material cost. Because the transition well cover 100 is dug out before the asphalt lower surface layer 400 is cooled, the asphalt mixture is small in digging difficulty, simple and convenient to construct and convenient to popularize.

Step S4, reinforcing the periphery of the well seat and the well cover 700: and pouring fine stone concrete 500 at the periphery of the preset installation position of the well seat and the well cover 700.

After the fine aggregate concrete 500 backfilled between the well base well cover 700 and the asphalt lower surface layer 400 is finally set, lateral restraint is formed on the well base well cover 700, the well base well cover 700 is prevented from moving laterally under the pushing effect of a road roller, the well base well cover 700 is only allowed to sink vertically, and local protrusions or pits generated by pushing of asphalt mixtures are reduced. The fine aggregate concrete 500 belongs to a temporary structure required in the process of the technical scheme, and does not play a role in using an asphalt surface layer and an inspection well after construction.

Step S5, installing the well base and the well lid 700: and (3) installing the well base and the well cover 700, and padding the well base and the well cover 700 with a mortar cushion layer.

Step S6, paving an asphalt upper surface layer 800: the asphalt top layer 800 begins to be laid before the mortar mat sets initially.

Before the mortar cushion layer at the bottom of the well seat well lid 700 is initially set, for example, within 1 hour after the mortar cushion layer is filled, paving of the asphalt upper layer 800 is started, and by utilizing the limited degree of plasticity of the mortar in the state close to the initial setting state, the well seat well lid 700 can be settled together with the asphalt upper layer 800 within a certain range, so that conditions are provided for integral rolling of the well seat well lid 700 and the asphalt upper layer 800.

After the paving of the asphalt upper surface layer 800 is completed, the asphalt mixture scattered on the surface of the well base and well cover 700 is manually swept, so that the well base and well cover 700 and the asphalt upper surface layer 800 can be integrally settled and integrally rolled and molded in the construction process.

Step S7, integral rolling: the well base and cover 700 and the asphalt upper layer 800 are rolled integrally.

The asphalt upper layer 800 is integrally rolled and formed without taking out the well seat and the well cover 700 or removing the asphalt mixture around the well, so that the technical processing requirement of well backfill is avoided.

And opening the traffic after the asphalt upper surface layer 800 is naturally cooled to below 50 ℃.

The main function of the transition well lid 100 is to prevent the asphalt mixture from falling into the inspection shaft 200, so that the asphalt lower surface layer 400 is paved and rolled by a machine, and is formed in one step without affecting the well flatness of the asphalt lower surface layer 400. Therefore, the requirement of the transitional well lid 100 on rigidity and geometric shape is not high, and the transitional well lid can be roughly adjusted to be approximately flat after deformation, so that the use requirement can be met.

The transition well cover 100 covers the inspection shaft 200, fine stone concrete 500 is poured on the periphery of the well seat and well cover 700 for reinforcement, and the well seat and well cover 700 is padded up by a mortar cushion layer to realize integral rolling, so that the compactness of the asphalt surface layer around the inspection shaft is improved, and the two flatness problems of the asphalt surface layer around the inspection shaft are solved. The transition well lid 100 provided by the invention has the advantages of simple structure, light weight and capability of being used repeatedly.

Preferably, referring to fig. 2, before the step of rolling the asphalt lower layer 400, a step of inserting a steel bar head into the asphalt mixture to locate and mark the transition manhole cover 100 is further included. The steel bar heads have larger touch feeling and make sound when impacting the transition well lid 100, so that the position of the transition well lid 100 can be conveniently found out. The markings are made to facilitate later retrieval and removal of the transition well lid 100.

Preferably, referring to fig. 3 and 7, the step of reinforcing the periphery of the well seat and the well lid 700 comprises: temporarily placing the well seat and the well cover 700 at a preset installation position, sleeving the inner mold steel ring 600 on the periphery of the well seat and the well cover 700, pouring the fine aggregate concrete 500, and taking out the well seat and the well cover 700 and the inner mold steel ring 600 after the fine aggregate concrete 500 is initially set. The inner mold steel ring 600 is used as an inner mold for pouring the fine stone concrete 500, and the well seat well cover 700 is positioned and supports the inner mold steel ring 600. The fine stone concrete 500 is tightly attached to the well seat and the well cover 700, and particularly, the pressure is not great at the axillary corner, so that the weak link of uneven settlement is not formed.

The thickness of the fine aggregate concrete 500 backfilled around the well seat and the well cover 700 can be controlled by self, and the fine aggregate concrete does not need to be leveled with the elevation of the asphalt lower surface layer 400, so that when the asphalt upper surface layer 800 is paved, the space around the well is abundant, a long, narrow and deep well back part does not exist, the asphalt mixture backfilling and integral rolling forming of the asphalt upper surface layer 800 are facilitated, and the well back part is not easy to become a defective part.

Preferably, referring to fig. 4, the step of installing the well lid 700 comprises: and drawing a cross line with the elevation of the flat stone to loft to a preset installation position of the well base and the well lid 700, and lifting upwards by 3-5 mm to control the installation elevation of the well base and the well lid 700. Flush according to design flat kerbstone elevation and pitch upper surface 800 design elevation, control well seat well lid 700's elevation according to the principle that exceeds pitch upper surface 800 design elevation 3 ~ 5 mm. The well base and the well lid 700 are settled due to the plasticity of the mortar cushion layer in the integral rolling process, and finally settled to the designed elevation of the asphalt upper layer 800 and flush with the asphalt upper layer 800.

Preferably, referring to fig. 4, before the step of spreading the asphalt upper layer 800, the method further comprises the step of covering the surface of the well base and well cover 700 with fiber paper, and brushing the surface of the fiber paper with an asphalt release agent. The fiber paper covers the surface of the well base and the well cover 700 to prevent the asphalt mixture from polluting the surface of the well base and the well cover 700. The asphalt separant is vegetable oil which is commonly used in asphalt construction and used for preventing asphalt mixture from adhering to a rubber wheel of a road roller, and has the main effects that the scattered asphalt mixture which is scattered on the surface of the well base and well cover 700 is prevented from adhering to the well base and well cover 700 and is difficult to remove, and the well base and well cover 700 sinks excessively under the action of the scattered asphalt mixture when the whole rolling is caused and is lower than the designed elevation.

Preferably, with reference to fig. 4, the integral rolling step comprises: when the double-steel-wheel road roller and the rubber-wheel road roller are rolled to the position near the well seat and well cover 700, the double-steel-wheel road roller and the rubber-wheel road roller roll the well seat and well cover 700 along the route opposite to the well seat and well cover 700, the adjacent wheel tracks avoid the position of the well seat and well cover 700, the wheel tracks of the periphery of the well seat and well cover 700 are repeatedly supplemented and rolled along the edge of the well seat and well cover 700 by the small-sized steel-wheel road roller, and the asphalt mixture pushed to the surface of the well seat and well cover 700.

The well base, the well cover 700 and the surrounding asphalt mixture are integrally rolled and formed by a double-steel-wheel road roller and a rubber-wheel road roller, and the compactness is guaranteed. In the rolling process, the asphalt mixture near the periphery of the well is compacted mainly by a small steel wheel road roller, and the running route of the road roller is reasonably organized, so that the rolling wheel inclination phenomenon and the formation of local pits caused by the rigidity difference between the well base and the well cover 700 and the asphalt mixture and the self weight of the road roller can be avoided.

The height of the well seat and well cover 700 can be always kept consistent with the height of the asphalt upper layer 800 by arranging a specially-assigned person to timely shovel off the asphalt mixture on the well seat and well cover 700 by using a shovel, so that the problems of insufficient compactness and poor well periphery flatness are avoided. The operation is simple, no additional auxiliary tool is required to be installed or arranged, and the cost is low.

Referring to fig. 5 and 6, according to another aspect of the present invention, there is provided a transition manhole cover 100 applied to the construction method for compacting the periphery of the asphalt pavement manhole, for covering a manhole shaft 200, wherein the transition manhole cover 100 includes a circular cover plate 110 and a plurality of blocking legs 120 located below the cover plate 110 and uniformly spaced along the circumferential direction of the cover plate 110, and the blocking legs 120 have an arc-shaped outer surface for contacting the manhole shaft 200 to limit horizontal movement of the transition manhole cover 100.

The transition well lid 100 is directly placed on the inspection shaft 200, the cover plate 110 is in surface contact with the inspection shaft 200, the horizontal displacement of the transition well lid 100 is limited by the blocking legs 120, the blocking legs 120 are also in surface contact with the inspection shaft 200 due to the arc-shaped outer surfaces, most of the vertical load of the rolling wheels is directly transmitted to the inspection shaft 200, the horizontal load is transmitted to the inspection shaft 200 by the blocking legs 120 below the cover plate 110, the transition well lid 100 is good in stress, low in deformation probability, high in production efficiency and low in cost, the requirement on the rigidity of the transition well lid 100 is low, and the contradiction between the rigidity and the production efficiency and the production cost can be coordinated.

Preferably, referring to fig. 5, a plurality of reinforcing ribs 121 connected to the leg shield 120 to support the leg shield 120 intersect at the center of the cover plate 110. The reinforcing ribs 121 can reinforce the structural strength of the transition well lid 100, so that the cover plate 110 is not easy to deform, and the blocking legs 120 are not easy to damage.

Preferably, referring to fig. 6, a plurality of handles 130 are provided above the cover plate 110 to facilitate movement of the transit manhole cover 100. Handle 130 may facilitate the covering of transition well lid 100 onto manhole 200 and the removal of transition well lid 100.

Preferably, referring to fig. 6, a nut 131 is sleeved on each end of the handle 130, and the nut 131 is welded to the cover plate 110. The handle 130 can rotate in the hole of the nut 131, so that the handle is convenient to hold by hands, and when the asphalt pavement paving machine is not used, the handle 130 can be tightly attached to the cover plate 110, so that the paving and rolling of the asphalt lower surface layer 400 cannot be influenced.
