Description

Technical Field

[0001] The invention relates to the technical field of inspection well construction, in particular to a road inspection well circumference reinforcement structure and a construction method. Background Art

[0002] In road engineering construction, after the construction of the road structure layer is completed, the construction of road ancillary projects will begin. Inspection well reinforcement and manhole cover installation are one of the road ancillary projects. After the construction of road ancillary projects is completed, the final road surface layer construction will begin. There are obstacles around the inspection wells due to mechanical compaction, and the construction quality is difficult to guarantee. This is an unavoidable problem and weak link in road engineering construction.

[0003] The road soil subgrade is a flexible structure with poor stability and is easily affected by working conditions and the environment; the road water-stable structure layer is a semi-rigid structure, but is also easily affected by the settlement of the underlying soil subgrade and the transmission of surface pressure; and the inspection well shaft is connected to the inspection well chamber and is a rigid structure, which is less affected by settlement.

[0004] From bottom to top, there are roadbed, structural layer and surface layer around the inspection well. The earth roadbed will settle due to insufficient compaction around the well and environmental factors such as water infiltration. The water-stable structural layer around the well will also settle and suffer structural damage due to the settlement of the roadbed. The settlement of the inspection well shaft is smaller than that of the well surrounding due to the buried depth of the well chamber. The difference in settlement between the well surrounding and the well shaft will eventually lead to problems such as settlement cracking around the well and protruding manhole covers. In severe cases, road traffic safety will be affected.

[0005] There are four common treatment methods for the treatment of the well area. The first is to do nothing around the well area and rely entirely on the roadbed and structural layer construction control; the second is to reverse excavate the 50cm area around the well area after the road structure layer construction is completed, and then pour concrete to strengthen it; the third is to expand the area around the well area after the road structure layer construction is completed, tie the steel mesh, and then pour concrete to strengthen it; the fourth is to use modules to isolate the well area during the road structure layer construction process, remove the modules after the structural layer construction is completed, and pour concrete to strengthen the well area;

[0006] Conventional treatment methods around wells have four disadvantages: 1. The size of the counter-excavation is difficult to control, resulting in a lot of waste of structural layer materials and difficulty in controlling the amount of cast-in-place concrete, which is not conducive to cost control; 2. The location around the well is limited, the construction is difficult, the process is complicated, and the construction period is long, which affects the efficiency of the construction period; 3. The mechanical vibration of the counter-excavation will affect the integrity of the surrounding road structure layer, and there will inevitably be risks and hidden dangers of damaging the road structure layer and the wellbore.

[0007] Based on this, the present invention designs a road inspection well circumference reinforcement structure and a construction method to solve the above problems. Summary of the invention

[0011] As a further solution of the present invention, the first connecting member has a first portion disposed in the lower clamping groove and a second portion disposed in the lower base layer.

[0012] As a further solution of the present invention, the connection structure includes a connecting ring arranged between the lower reinforcement ring and the wellbore, the inner cavity wall of the connecting ring is fixedly connected to the outer ring wall of the wellbore, and the outer ring wall of the connecting ring is fixedly connected to the inner cavity wall of the lower reinforcement ring.

[0013] As a further solution of the present invention, the connection structure includes connecting ribs whose two ends are respectively fixed to the wellbore and the lower reinforcement ring. There are a plurality of connecting ribs, and the plurality of connecting ribs are arranged at equal intervals along the circumference of the wellbore.

[0014] As a further solution of the present invention, a connecting column is fixedly provided in the upper reinforcement ring, and the bottom end of the connecting column is inserted into the lower reinforcement ring and fixedly connected with the lower reinforcement ring.

[0015] As a further solution of the present invention, a connecting layer is formed between the lower reinforcement ring and the upper reinforcement ring, and the connecting layer is used to connect the upper reinforcement ring and the lower reinforcement ring.

[0016] As a further solution of the present invention, a mounting groove is provided at the top of the upper reinforcement ring, a third connecting member is provided in the mounting groove, and the third connecting member is used to fix the well seat and the hook of the inspection well.

[0017] A road inspection well perimeter construction method is used to construct the above-mentioned road inspection well perimeter reinforcement structure, comprising:

[0018] Shaft adjustment and reinforcement planting: Measure the elevation of the top surface of the lower base on the completed roadbed to make the elevation of the shaft top surface consistent with the elevation of the lower base surface, and drill holes on the shaft surface to implant connecting reinforcement;

[0019] Installation of the lower reinforcement ring: The prefabricated lower reinforcement ring is sleeved on the wellbore, so that the elevation of the top surface of the lower reinforcement ring is the same as that of the top surface of the wellbore. The lower reinforcement ring is preset with connection ribs. When sleeved with the lower reinforcement ring, the preset connection ribs in the lower reinforcement ring are made to correspond to the connection ribs on the wellbore one by one. The opening size of the inner cavity of the lower reinforcement ring is larger than the outer diameter of the wellbore, so as to form a connection groove between the inner cavity wall of the lower reinforcement ring and the outer wall of the wellbore;

[0020] Paving and rolling of the lower base: Install a clamping block for blocking the lower clamping groove in the lower clamping groove, and use the mixture of the lower base to pave the lower base, so that the lower base wraps the lower reinforcement ring and the clamping block from the side, and take out the clamping block in the lower clamping groove after the lower base is formed;

[0021] Horizontal connection of the lower reinforcement ring: weld and fix the preset connection ribs on the lower reinforcement ring to the connection ribs implanted on the shaft, pour concrete in the connection groove between the lower reinforcement ring and the shaft, and pour concrete at the original clamping block position;

[0022] Installation of upper reinforcement ring: Then move the prefabricated upper reinforcement ring to the lower reinforcement ring, while ensuring that the top surface elevation of the upper reinforcement ring is the same as the top surface elevation of the upper base layer;

[0023] Paving and rolling of the upper base: a profiling module for closing the upper clamping groove is sleeved on the outer side of the upper reinforcement ring, and the upper base is paved with the mixture of the upper base so that the upper base wraps the outer side of the profiling module. After the upper base is rolled and formed, the profiling module is taken out;

[0024] Horizontal and vertical connection of the upper reinforcement ring: pour concrete at the original position of the contoured template and in the upper clamping groove to form a second connection piece, and pour concrete in the upper reserved hole and the lower reserved hole to form a connection column;

[0025] Installation of the well seat: Spread concrete in the installation groove opened on the top of the upper reinforcement ring, bury the hook in the concrete in the installation groove, with the hook facing the axis of the wellbore, then place the well seat on the concrete in the installation groove, adjust the well seat to be coaxial with the wellbore, and wrap the concrete on the outside of the bottom of the well seat to fix the well seat;

[0026] Surface paving and rolling: Install the manhole cover on the manhole seat, and then spread and roll the surface layer.

[0027] The present invention has the following beneficial effects:

[0028] The present invention divides the wellbore reinforcement structure into two parts in the vertical direction and controls the height of the wellbore top surface so that the wellbore top surface and the lower reinforcement ring top surface are in the same plane with the lower base layer top surface. In this way, the lower reinforcement ring and the wellbore will not interfere with the paving and compacting of the lower base layer, so that no weak area will appear around the wellbore when the lower base layer is paved and compacted. Similarly, the top surface of the upper reinforcement ring and the top surface of the upper base layer are in the same plane, that is to say, the upper reinforcement ring will not interfere with the paving and compacting of the upper base layer after installation, and no weak area will appear around the wellbore when the upper base layer is paved and compacted, thereby ensuring the compaction effect of the upper and lower base layers. At the same time, the construction of the wellbore reinforcement structure is completely integrated with the construction of the road structure layer, eliminating the subsequent excavation process, saving working procedures, accelerating the construction progress, and reducing the generation of waste. While saving costs, the overall construction process is made more green and environmentally friendly.

[0029] In addition to the above-described purposes, features and advantages, the present invention has other purposes, features and advantages. The present invention will be further described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0041] See also Figure 1-6 The present invention provides a technical solution: a road inspection well peripheral reinforcement structure, arranged between the outer wall surface of the well shaft 1 and the road structure layer, including a lower reinforcement ring 2 and an upper reinforcement ring 3;

[0042] The lower reinforcing ring 2 is sleeved on the shaft 1, the top surface of the lower reinforcing ring 2 and the top surface of the shaft 1 are both in the same plane as the top surface of the lower base layer 41 in the road structure layer, and a connecting structure for fixing the lower reinforcing ring 2 to the shaft 1 is provided between the lower reinforcing ring 2 and the shaft 1;

[0043] The upper reinforcing ring 3 is placed on the shaft 1 and the lower reinforcing ring 2, and the top surface of the upper reinforcing ring 3 is in the same plane as the top surface of the upper base layer 42 in the road structure layer;

[0044] like Figure 2 As shown, the top surface of the lower reinforcement ring 2 and the top surface of the shaft 1 are both in the same plane with the top surface of the lower base layer 41 in the road structure layer, that is, after the lower reinforcement ring 2 is installed, the top surface of the lower reinforcement ring 2 and the top surface of the shaft 1 are in the same horizontal plane, and at the same time, the top surface of the lower base layer 41 to be paved is in the same plane as the top surface of the lower reinforcement ring 2 and the top surface of the shaft 1. When paving and rolling the lower base layer 41, the construction equipment can pass through the lower reinforcement ring 2 and the top surface of the shaft 1, and the lower reinforcement ring 2 and the shaft 1 will not interfere with the construction equipment, and the paving of the lower base layer 41 can be carried out normally. Rolling, and can also ensure that the surrounding of the shaft 1 is rolled in place when the lower base layer 41 is paved and rolled, and at the same time, the top surface of the upper reinforcing ring 3 is in the same plane with the top surface of the upper base layer 42 in the road structure layer, that is, after the upper reinforcing ring 3 is installed, the top surface of the upper reinforcing ring 3 is in the same plane with the top surface of the upper base layer 42 to be paved, and the upper reinforcing ring 3 will not interfere with the paving and rolling of the upper base layer 42. After the upper reinforcing ring 3 is installed, the paving and rolling of the upper base layer 42 can be carried out normally, and it can also ensure that the surrounding of the shaft 1 is rolled in place when the upper base layer 41 is paved and rolled;

[0045] By splitting the well surrounding reinforcement structure into the lower reinforcement ring 2 and the upper reinforcement ring 3 in the vertical direction, and controlling the heights of the wellbore top surface, the lower reinforcement ring top surface and the upper reinforcement ring top surface, the construction of the well surrounding reinforcement structure can be integrated into the construction of the road structure layer and constructed synchronously with the road structure layer, thereby eliminating the subsequent excavation process, saving working procedures, speeding up the construction progress, and reducing the generation of waste materials. While saving costs, the overall construction process is made greener and more environmentally friendly. At the same time, the compaction degree of the road structure layer around the well can be ensured, so as to improve the anti-settling effect of the well surrounding reinforcement structure and the road structure layer around the well;

[0046] An annular mounting groove 33 is opened at the top of the upper reinforcing ring 3. The diameter of the mounting groove 33 is larger than the diameter of the well seat 11 and is used to install the well seat 11. After the installation of the lower reinforcing ring 2 and the upper reinforcing ring 3 is completed, the well seat 11 is installed in the mounting groove 33 opened at the top of the upper reinforcing ring 3 for assembling the manhole cover.

[0047] In this structure, the lower reinforcement ring 2 is connected to the shaft 1 through a connecting structure, and the upper reinforcement ring 3 is placed on the shaft 1 and the lower reinforcement ring 2. The lower reinforcement ring 2 and the upper reinforcement ring 3 are subjected to force together with the shaft 1 as a whole, which can effectively improve the anti-subsidence effect around the shaft 1, reduce the amplitude of subsidence around the shaft 1, and improve the service life of the road surface. At the same time, by controlling the height of the top surface of the upper reinforcement ring 3 and the lower reinforcement ring 2, the present structure can be constructed synchronously with the road structure layer without affecting the construction of the road structure layer, eliminating the subsequent process of excavating and filling concrete around the shaft 1, saving working procedures, speeding up the construction progress, and reducing the use of materials and the generation of waste, which is more environmentally friendly.

[0048] At the same time, when the lower base layer 41 and the upper base layer 42 are being spread and rolled, there will be no obstacles for the spreading and rolling machinery around the wellbore 1, and the lower base layer 41 and the upper base layer 42 can be completely rolled to improve the compaction quality of the lower base layer 41 and the upper base layer 42 around the wellbore 1, and further enhance the anti-subsidence effect.

[0049] The lower reinforcement ring 2 and the upper reinforcement ring 3 are prefabricated with reinforced concrete.

[0050] Further, such as Figure 3 As shown, the outer wall of the lower reinforcement ring 2 is provided with a plurality of lower clamping grooves 21, and a first connecting member 22 is fixedly disposed in the lower clamping groove 21. The first connecting member 22 is fixedly connected to the lower base layer 41 on a side away from the center of the lower reinforcement ring 2;

[0051] The lower reinforcement ring 2 and the lower base layer 41 are connected by the first connecting member 22, so that the first reinforcement ring can slow down the settlement of the lower base layer 41 around it. The settlement of the lower base layer 41 closer to the lower reinforcement ring 2 is less obvious. When the lower base layer 41 around the lower reinforcement ring 2 settles, an inclined buffer area can be formed around the lower reinforcement ring 2, which can effectively reduce the probability of cracking of the road surface when settlement occurs, improve the service life of the road surface, and ensure the comfort of vehicles driving on the road surface.

[0052] Further, such as Figure 4 As shown, the first connecting member 22 has a first portion disposed in the lower engaging groove 21 and a second portion disposed in the lower base layer 41 .

[0053] The first connecting member 22 is fixedly connected to the lower reinforcement ring 2 by the first portion being clamped into the lower clamping groove 21, and is fixedly connected to the lower base layer 41 by the second portion being clamped in the lower base layer 41, while increasing the contact area with the lower reinforcement ring 2 and the lower base layer 41, thereby enhancing the connection effect of the first connecting member 22 on the lower reinforcement ring 2 and the lower base layer 41, thereby improving the anti-settling effect around the well.

[0054] Further, such as Figure 5 As shown, the outer wall surface of the upper reinforcing ring 3 is provided with a plurality of upper clamping grooves 31, and a second connecting member 32 is fixedly arranged in the upper clamping groove 31. The second connecting member 32 is fixedly connected to the upper base layer 42 on a side away from the center of the upper reinforcing ring 3;

[0055] Similarly, the upper reinforcement ring 3 and the upper base layer 42 are connected by the second connecting member 32, so that the second reinforcement ring can alleviate the settlement of the upper base layer 42 around it, further reduce the probability of cracking of the road surface when settlement occurs, further improve the service life of the road surface, and improve the comfort of vehicles driving on the road surface.

[0056] Preferably, Figure 2 As shown, the vertical projection of the upper reinforcement ring 3 is smaller than the vertical projection of the lower reinforcement ring 2, so that after the upper reinforcement ring 3 is fixed on the lower reinforcement ring 2, the top surface of the lower reinforcement ring 2 will contact the second connecting member 32 and part of the second base layer, and the second connecting member 32 and the second base layer close to the upper reinforcement ring 3 can be supported by the lower reinforcement ring 2, thereby further improving the integrity of the overall structure and further improving the anti-settling effect.

[0057] Further, such as Figure 2 As shown, the connection structure includes a connection ring 23 disposed between the lower reinforcement ring 2 and the wellbore 1, the inner cavity wall of the connection ring 23 is fixedly connected to the outer ring wall of the wellbore 1, and the outer ring wall of the connection ring 23 is fixedly connected to the inner cavity wall of the lower reinforcement ring 2;

[0058] The shaft 1 and the lower reinforcement ring 2 are connected by the connecting ring 23, so that the lower reinforcement ring 2 and the shaft 1 form a whole and are subjected to force together, thereby improving the anti-settling effect of the lower reinforcement ring 2 and further increasing the anti-settling effect of the overall wellbore reinforcement structure.

[0059] Further, such as Figure 3-4 As shown, the connection structure includes a connection rib 24 fixed at both ends to the wellbore 1 and the lower reinforcement ring 2, and a plurality of connection ribs 24 are provided, and the plurality of connection ribs 24 are arranged at equal intervals along the circumference of the wellbore 1;

[0060] The shaft 1 and the lower reinforcement ring 2 are connected by connecting ribs 24, so that the lower reinforcement ring 2 and the shaft 1 form a whole, reducing the settlement of the lower reinforcement ring 2, and thereby reducing the probability of cracking of the road surface around the shaft. In this example, the lower reinforcement ring 2 and the shaft 1 are connected by connecting ribs 24 and connecting rings 23 at the same time, thereby making the connection between the lower reinforcement ring 2 and the shaft 1 better, thereby improving the anti-settlement effect of the lower reinforcement ring 2.

[0061] The lower reinforcing ring 2 and the shaft 1 are connected by connecting ribs 24, thereby improving the connection effect between the shaft 1 and the lower reinforcing ring 2, improving the connection reliability between the lower reinforcing ring 2 and the shaft 1, and further improving the anti-settling effect of the shaft 1 on the lower reinforcing ring 2, thereby improving the service life of the road surface.

[0062] Preferably, the connecting ribs 24 are arranged between the lower reinforcing ring 2 and the wellbore 1 at equal intervals along the circumference of the wellbore 1, so that the wellbore 1 is subjected to balanced force.

[0063] Furthermore, a connecting column 5 is fixedly disposed in the upper reinforcing ring 3, and the bottom end of the connecting column 5 is inserted into the lower reinforcing ring 2 and fixedly connected to the lower reinforcing ring 2;

[0064] The connection strength between the upper reinforcement ring 3 and the lower reinforcement ring 2 is improved, so that the connection between the upper reinforcement ring 3 and the lower reinforcement ring 2 is more stable, thereby enhancing the overall strength of the well peripheral reinforcement structure.

[0065] Further, such as Figure 2 As shown, a connecting layer 6 is formed between the lower reinforcing ring 2 and the upper reinforcing ring 3, and the connecting layer 6 is connected to the lower reinforcing ring 2 and the upper reinforcing ring 3 at the same time, so as to strengthen the connection between the upper reinforcing ring 3 and the lower reinforcing ring 2, improve the connection reliability, and further improve the anti-settling effect of the overall reinforced structure.

[0066] like Figure 7 As shown, a method for constructing the perimeter of a road inspection well is used to construct the above-mentioned road inspection well perimeter reinforcement structure, comprising:

[0067] Shaft 1 adjustment and reinforcement planting: Measure the top elevation of the lower base 41 on the completed roadbed to make the top elevation of the shaft 1 consistent with the surface elevation of the lower base 41, and drill holes on the surface of the shaft 1 to implant the connecting reinforcement 24;

[0068] Only when the elevation of the top surface of the wellbore 1 is consistent with the elevation of the lower base 41, the wellbore 1 will not interfere with the construction of the lower base 41. When adjusting the elevation of the top surface of the wellbore 1, the wellbore 1 can be cut or connected to reduce or increase the height of the top surface of the wellbore 1.

[0069] Since the shaft 1 needs to be installed before the road structure layer and the reinforcement structure are constructed, and the elevation of the shaft 1 needs to be adjusted after the shaft 1 is installed, the connecting rib 24 can only be installed after the shaft 1 is installed and the elevation is adjusted;

[0070] When installing the connecting ribs 24, the connecting ribs 24 are installed at equal intervals along the circumference of the wellbore 1, and the number of the connecting ribs 24 is selected according to the actual situation on site;

[0071] Preferably, in this example, connecting bars 24 are installed at four locations on the shaft 1 at equal intervals along the circumference of the shaft 1 by embedding reinforcement bars, and the connecting bars 24 at each location are arranged in double rows, with three bars in each row.

[0072] Installation of the lower reinforcing ring 2: The prefabricated lower reinforcing ring 2 is sleeved onto the wellbore 1, so that the elevation of the top surface of the lower reinforcing ring 2 is the same as that of the top surface of the wellbore 1. A connection rib 24 is preset in the lower reinforcing ring 2. When sleeved, the connection rib 24 preset in the lower reinforcing ring 2 corresponds to the connection rib 24 on the wellbore 1. The opening size of the inner cavity of the lower reinforcing ring 2 is larger than the outer diameter of the wellbore 1, so as to form a connection groove 25 between the inner cavity wall of the lower reinforcing ring 2 and the outer wall of the wellbore 1;

[0073] The connection strength between the connection rib 24 and the lower reinforcing ring 2 can be increased by presetting the connection rib 24;

[0074] Preferably, in this example, the lower reinforcement ring 2 is a circular ring, and the inner diameter of the lower reinforcement ring 2 is larger than the outer diameter of the wellbore 1. When installing the lower reinforcement ring 2, the lower reinforcement ring 2 is made coaxial with the wellbore 1, so that a connecting groove 25 can be formed between the inner wall of the lower reinforcement ring 2 and the outer wall of the wellbore 1;

[0075] The lower base layer 41 is paved and rolled: a clamping block 26 for blocking the lower clamping groove 21 is installed in the lower clamping groove 21, and the lower base layer 41 is paved with the mixed material of the lower base layer 41, so that the lower base layer 41 wraps the lower reinforcement ring 2 and the clamping block 26 from the side, and the clamping block 26 in the lower clamping groove 21 is taken out after the lower base layer 41 is formed;

[0076] Since the top surface of the lower reinforcing ring 2 and the top surface of the shaft 1 are at the same elevation as the lower base 41, when paving and rolling the lower base 41, the lower reinforcing ring 2 and the shaft 1 will not interfere with the paving and rolling equipment, and the lower base 41 can be paved and rolled normally;

[0077] When the lower base layer 41 is rolled, in order to prevent the mixed material used in the lower base layer 41 from entering the lower clamping groove 21, a clamping block 26 is pre-installed in the lower clamping groove 21, and the lower clamping groove 21 is blocked by the clamping block 26 to prevent the mixed material of the lower base layer 41 from entering the lower clamping groove 21 when the lower base layer 41 is paved. After the lower base layer 41 is paved and rolled, the clamping block 26 is removed from the lower clamping groove 21 to form a cavity in the lower clamping groove 21.

[0078] Horizontal connection of the lower reinforcing ring 2: The preset connection ribs 24 on the lower reinforcing ring 2 are welded and fixed to the connection ribs 24 implanted on the shaft 1, and concrete is poured in the connection groove 25 between the lower reinforcing ring 2 and the shaft 1, and concrete is poured at the original position of the clamping block 26;

[0079] After the lower reinforcing ring 2 is installed, the connecting ribs 24 on the lower reinforcing ring 2 are still separated from the connecting ribs 24 on the shaft 1. At this time, the connecting ribs 24 obviously cannot achieve the effect of connecting the shaft 1 and the lower reinforcing ring 2. Therefore, it is necessary to fix the connecting ribs 24 implanted on the shaft 1 with the connecting ribs 24 preset in the lower reinforcing ring 2. The fixing can be done by welding.

[0080] The connection ring 23 is formed by pouring concrete in the connection groove 25 and waiting for the concrete to solidify. Similarly, the first connection member 22 is formed by pouring concrete in the lower clamping groove 21 and waiting for the concrete to solidify.

[0081] Installation of the upper reinforcement ring 3: Then move the prefabricated upper reinforcement ring 3 onto the lower reinforcement ring 2, while ensuring that the top surface elevation of the upper reinforcement ring 3 is the same as the top surface elevation of the upper base layer 42;

[0082] A groove is provided on the top surface of the lower reinforcing ring 2. The bonding mortar is filled in the groove on the top of the lower reinforcing ring 2, and then the upper reinforcing ring 3 is placed on the lower reinforcing ring 2. After the bonding mortar solidifies, a connecting layer 6 is formed. The connecting layer 6 is fixedly connected to the lower reinforcing ring 2 and the upper reinforcing ring 3 at the same time.

[0083] The groove is opened on the top surface of the lower reinforcement ring 2, and the thickness and shape of the connection layer 6 can be controlled through the groove to ensure the stability of the connection layer 6. At the same time, it will not affect the contact between the upper reinforcement ring 3 and the lower reinforcement ring 2, which is more conducive to controlling the height of the upper reinforcement ring 3;

[0084] A vertically penetrating lower reserved hole 27 is formed on the lower reinforcing ring 2, and a vertically penetrating upper reserved hole 34 is formed on the upper reinforcing ring 3. When placing the upper reinforcing ring 3, the upper reserved hole 34 formed on the upper reinforcing ring 3 needs to be aligned with the lower reserved hole 27 formed on the lower reinforcing ring 2 to prevent the upper reinforcing ring 3 from being unable to be moved after the bonding mortar solidifies.

[0085] The upper base layer 42 is spread and rolled: a profiling template 35 for closing the upper clamping groove 31 is attached to the outer side of the upper reinforcing ring 3, and the upper base layer 42 is spread with the mixed material of the upper base layer 42 so that the upper base layer 42 wraps the outer side of the profiling template 35, and the profiling template 35 is taken out after the upper base layer 42 is rolled and formed;

[0086] Since the elevation of the top surface of the upper reinforcing ring 3 is consistent with the elevation of the top surface of the upper base layer 42, the upper reinforcing ring 3 will not interfere with the paving and rolling equipment when the upper base layer 42 is paved. After the upper reinforcing ring 3 is installed, the paving work of the upper base layer 42 can be carried out normally, saving construction procedures.

[0087] When paving the upper base layer 42, in order to prevent the mixed material of the upper base layer 42 from entering the upper clamping groove 31, it is necessary to sleeve the outer side of the upper reinforcing ring 3 through the profiling template 35, and close the upper clamping groove 31 through the profiling template 35 to prevent the mixed material of the upper base layer 42 from entering the upper clamping groove 31 when paving the upper base layer 42. After the upper base layer 42 is paved and rolled to form, the profiling template 35 is taken out to form a cavity in the upper clamping groove 31, and a gap is formed between the upper reinforcing ring 3 and the upper base layer 42.

[0088] The upper reinforcing ring 3 is connected horizontally and vertically: concrete is poured at the original position of the contour template 35 and in the upper clamping groove 31 to form the second connecting member 32, and concrete is poured into the upper reserved hole 34 and the lower reserved hole 27 to form the connecting column 5;

[0089] By pouring concrete at the original position of the contour template 35 and in the upper clamping groove 31, the concrete fills the gap between the upper reinforcing ring 3 and the upper base layer 42 and the upper clamping groove 31, and the second connecting member 32 is formed after the concrete solidifies;

[0090] Installation of the well seat 11: concrete is spread in the installation groove 33 opened at the top of the upper reinforcing ring 3, and the hook 12 is buried in the concrete in the installation groove 33, with the hook 12 facing the axis of the well shaft 1. Then, the well seat 11 is placed on the concrete in the installation groove 33, and the well seat 11 is adjusted to be coaxial with the well shaft 1. Concrete is wrapped around the outside of the bottom of the well seat 11, and the concrete is solidified to form the third connecting member 34;

[0091] The hook 12 and the well seat 11 are fixed in the mounting groove 33 opened at the top of the upper reinforcing ring 3 by concrete solidification;

[0092] Paving and rolling of the surface layer 43: the manhole cover is installed on the manhole seat 11, and then the surface layer 43 is paved and rolled;

[0093] The method comprises the following steps: paving the lower base layer 41 after the lower reinforcement ring 2 is installed, constructing the upper base layer 42 after the upper reinforcement ring 3 is installed, and forming the first connecting member 22 by the cooperation of the upper clamping groove 31 and the clamping block 26, and forming the second connecting member 32 by the cooperation of the upper clamping groove 31 and the contoured template 35. The construction of the well perimeter reinforcement structure and the construction of the road structure layer are completely integrated, thus saving the overall construction process and greatly improving the construction efficiency. At the same time, there is no need to excavate the well perimeter and fill it with concrete, which effectively reduces the waste of materials and is more economical and environmentally friendly.

[0094] like Figure 3 As shown, the length of the clamping block 26 is greater than the radial depth of the lower clamping groove 21, so that after the clamping block 26 is inserted into the lower clamping groove 21, any part of the clamping block 26 protrudes from the lower clamping groove 21, so that the clamping block 26 can be wrapped by the lower base layer 41 when paving the lower base layer 41, and then after the clamping block 26 is taken out, a cavity will be formed at the adjacent position of the lower base layer 41 and the lower clamping groove 21. At this time, concrete is poured into the cavity formed by the lower clamping groove 21 and the first base layer to form a first connecting member 22 having a first part and a second part.

[0095] like Figure 3 As shown, a pull ring is provided on the top of the clamping block 26 so that the clamping block 26 can be taken out through the pull ring after the lower base layer 41 is paved.

[0096] like Figure 5 As shown, the contour template 35 is spliced ​​from multiple parts, so that it is more convenient to take out the contour template 35 after the upper base layer 42 is paved and rolled.

[0097] like Figure 5 As shown, in this example, the upper reinforcement ring 3 is in a circular shape, and the inner diameter of the upper reinforcement ring 3 is larger than the inner diameter of the wellbore 1. When installing the upper reinforcement ring 3, the upper reinforcement ring 3 is coaxially arranged with the wellbore 1. Since the inner diameter of the upper reinforcement ring 3 is smaller than the inner diameter of the wellbore 1, after the well seat 11 is finally installed, cement mortar can be applied to the inner wall of the upper reinforcement ring 3 to level the inner wall of the wellbore 1, so that there is a smooth transition between the inner wall of the wellbore 1 and the well seat 11.

[0098] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
