[0003] The road soil subgrade belongs to the flexible structure, and the stability is poor, and is easily influenced by the working condition and environment; the road water stable structure layer belongs to the semi-rigid structure, but is also easily influenced by the lower soil subgrade settlement and surface layer pressure transmission; and the inspection well shaft is connected from the inspection well chamber, and belongs to the rigid structure, and the settlement influence is small.

[0004] The inspection well periphery is the subgrade, structure layer and surface layer from bottom to top, the soil subgrade appears settlement due to the insufficient periphery compaction and the environment such as moisture penetration, the periphery water stable structure layer is also influenced by the subgrade settlement and appears settlement, structure damage and the like, and the inspection well shaft is small in settlement amount due to the chamber burial depth; the different settlement amounts of the periphery and the shaft finally lead to the periphery settlement cracking, well lid protrusion and the like, and the serious one influences the road traffic safety.

[0005] The common treatment method of the periphery is four kinds of treatment modes, one is that the periphery is not treated in any way, and is relied on the subgrade and structure layer construction control; two is that the periphery 50cm range is back excavated after the road structure layer construction is completed, and then the concrete is poured to reinforce; three is that the periphery is back excavated in the expanded range after the road structure layer construction is completed, and then the reinforcing mesh is bound, and the concrete is poured to reinforce; four is that the periphery position is isolated by using the module in the road structure layer construction process, and then the module is removed after the structure layer construction is completed, and the periphery is poured with the concrete to reinforce.

[0030] The embodiments of the present application are described in detail below with reference to the drawings, but the present application can be implemented in various different ways as defined and covered by the following.

[0031] Please refer to Figures 1-6 , the present application provides a technical scheme: a road inspection well peripheral reinforcing structure, which is arranged between the outer wall surface of the wellbore 1 and the road structure layer, and comprises a lower reinforcing ring 2 and an upper reinforcing ring 3.

[0032] The lower reinforcing ring 2 is sleeved on the wellbore 1, and the top surface of the lower reinforcing ring 2 and the top surface of the wellbore 1 are 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 wellbore 1 is arranged between the lower reinforcing ring 2 and the wellbore 1.

[0033] The upper reinforcing ring 3 is placed on the wellbore 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.

[0034] As Figure 2 shown, the top surface of the lower reinforcing ring 2 and the top surface of the wellbore 1 are in the same plane as the top surface of the lower base layer 41 in the road structure layer, that is, after the installation of the lower reinforcing ring 2 is completed, the top surface of the lower reinforcing ring 2 and the top surface of the wellbore 1 are in the same horizontal plane, and the top surface of the lower reinforcing ring 2 and the top surface of the wellbore 1 are in the same plane as the top surface of the lower base layer 41 which needs to be paved, and when the lower base layer 41 is paved and rolled, the construction equipment can pass from the top surface of the lower reinforcing ring 2 and the wellbore 1, and the lower reinforcing ring 2 and the wellbore 1 will not interfere with the construction equipment, so that the paving and rolling of the lower base layer 41 can be normally carried out, and it can also ensure that the rolling around the wellbore 1 is in place when the lower base layer 41 is paved and rolled, 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, that is, after the installation of the upper reinforcing ring 3 is completed, the top surface of the upper reinforcing ring 3 and the top surface of the upper base layer 42 which needs to be paved are in the same plane, and the upper reinforcing ring 3 will not interfere with the paving and rolling of the upper base layer 42, so that the paving and rolling of the upper base layer 42 can be normally carried out after the installation of the upper reinforcing ring 3 is completed, and it can also ensure that the rolling around the wellbore 1 is in place when the upper base layer 41 is paved and rolled.

[0035] By splitting the well circumference reinforcing structure from the vertical direction into a lower reinforcing ring 2 and an upper reinforcing ring 3, and controlling the well bore top surface, the lower reinforcing ring top surface and the upper reinforcing ring top surface height, the construction of the well circumference reinforcing structure can be integrated into the road structure layer construction and constructed synchronously with the road structure layer, eliminating the subsequent excavation process, saving the process, accelerating the construction progress, while reducing the generation of waste, saving costs while making the overall construction process more environmentally friendly, while also ensuring the compaction degree of the road structure layer around the well, to improve the anti-settling effect of the well circumference reinforcing structure and the well circumference road structure layer;

[0036] The upper reinforcing ring 3 has a ring-shaped mounting groove 33 at the top, and the diameter of the mounting groove 33 is greater than the diameter of the well seat 11 for mounting the well seat 11. After the lower reinforcing ring 2 and the upper reinforcing ring 3 are installed, the well seat 11 is installed in the mounting groove 33 at the top of the upper reinforcing ring 3 for assembling the well cover.

[0037] In the structure, the lower reinforcing ring 2 is connected to the well bore 1 through a connecting structure, and the upper reinforcing ring 3 is placed on the well bore 1 and the lower reinforcing ring 2. The lower reinforcing ring 2 and the upper reinforcing ring 3 are in overall stress with the well bore 1, which can effectively improve the anti-settling effect around the well bore 1, reduce the settlement amplitude around the well bore 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 reinforcing ring 3 and the lower reinforcing ring 2, the structure can be constructed synchronously with the road structure layer, which will not affect the construction of the road structure layer, and the subsequent process of excavating and filling concrete around the well bore 1 is saved, saving the process, accelerating the construction progress, while reducing the use of materials and the generation of waste, and more environmentally friendly.

[0038] At the same time, when paving and rolling the lower base layer 41 and the upper base layer 42, the paving and rolling machinery will not be hindered around the well bore 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 well bore 1, and further improve the anti-settling effect.

[0039] The lower reinforcing ring 2 and the upper reinforcing ring 3 are made of reinforced concrete.

[0040] Further, as shown in Figure 3 The lower reinforcing ring 2 has a plurality of lower clamping grooves 21 on the outer wall surface, and a first connecting piece 22 is fixedly arranged in the lower clamping groove 21. One side of the first connecting piece 22 away from the center of the lower reinforcing ring 2 is fixedly connected with the lower base layer 41;

[0041] The first connecting piece 22 connects the lower reinforcing ring 2 and the lower base layer 41, so that the first reinforcing ring can slow down the settlement of the surrounding lower base layer 41, and the settlement of the part of the lower base layer 41 closer to the lower reinforcing ring 2 is less obvious, so that when the lower base layer 41 around the lower reinforcing ring 2 settles, an inclined buffer area can be formed around the lower reinforcing ring 2, which can effectively reduce the cracking probability of the pavement when it settles, prolong the service life of the pavement, and ensure the comfort of the pavement when the vehicle drives.

[0042] Further, as shown in Figure 4 The first connecting piece 22 has a first part arranged in the lower clamping groove 21 and a second part arranged in the lower base layer 41.

[0043] The first connecting piece 22 is fixedly connected with the lower reinforcing ring 2 by clamping the first part into the lower clamping groove 21, and is fixedly connected with the lower base layer 41 by clamping the second part in the lower base layer 41, while increasing the contact area with the lower reinforcing ring 2 and the lower base layer 41, enhancing the connection effect of the first connecting piece 22 on the lower reinforcing ring 2 and the lower base layer 41, and further improving the anti-settlement effect around the well.

[0044] Further, as shown in Figure 5 The upper reinforcing ring 3 has a plurality of upper clamping grooves 31 formed on the outer wall surface, and the second connecting piece 32 is fixedly arranged in the upper clamping groove 31, and the side of the second connecting piece 32 away from the center of the upper reinforcing ring 3 is fixedly connected with the upper base layer 42.

[0045] Similarly, the second connecting piece 32 connects the upper reinforcing ring 3 and the upper base layer 42, so that the second reinforcing ring can alleviate the settlement of the surrounding upper base layer 42, further reduce the cracking probability of the pavement when it settles, further prolong the service life of the pavement, and improve the comfort of the pavement when the vehicle drives.

[0046] Preferably, as shown in Figure 2 The vertical projection of the upper reinforcing ring 3 is smaller than the vertical projection of the lower reinforcing ring 2, so that after the upper reinforcing ring 3 is fixed on the lower reinforcing ring 2, the top surface of the lower reinforcing ring 2 will be in contact with the second connecting piece 32 and part of the second base layer, and the second connecting piece 32 and the position of the second base layer close to the upper reinforcing ring 3 can be supported by the lower reinforcing ring 2, further improving the integrity of the overall structure and further improving the anti-settlement effect.

[0047] Further, as shown in Figure 2 The connecting structure includes a connecting ring 23 arranged between the lower reinforcing ring 2 and the well shaft 1, the inner cavity wall of the connecting ring 23 is fixedly connected with the outer ring wall of the well shaft 1, and the outer ring wall of the connecting ring 23 is fixedly connected with the inner cavity wall of the lower reinforcing ring 2.

[0048] The well casing 1 and the lower reinforcing ring 2 are connected by the connecting ring 23, so that the lower reinforcing ring 2 and the well casing 1 form a whole and share the force, thereby improving the anti-settlement effect of the lower reinforcing ring 2 and increasing the anti-settlement effect of the overall well perimeter reinforcement structure.

[0049] Furthermore, such as Figures 3-4 As shown, the connection structure includes connecting ribs 24 fixed at both ends to the well shaft 1 and the lower reinforcing ring 2 respectively. There are several connecting ribs 24, and the several connecting ribs 24 are arranged at equal intervals along the circumference of the well shaft 1.

[0050] The manhole casing 1 and the lower reinforcing ring 2 are connected by connecting rib 24, so that the lower reinforcing ring 2 and the manhole casing 1 form a whole, reducing the settlement of the lower reinforcing ring 2 and thus reducing the probability of cracking of the road surface around the manhole. In this example, the lower reinforcing ring 2 and the manhole casing 1 are connected by both connecting rib 24 and connecting ring 23, which makes the connection between the lower reinforcing ring 2 and the manhole casing 1 better and improves the anti-settlement effect of the lower reinforcing ring 2.

[0051] The lower reinforcing ring 2 is connected to the manhole 1 by the connecting rib 24, which improves the connection effect between the manhole 1 and the lower reinforcing ring 2, improves the connection reliability between the lower reinforcing ring 2 and the manhole 1, thereby improving the anti-settlement effect of the manhole 1 on the lower reinforcing ring 2 and extending the service life of the road surface.

[0052] Preferably, the connecting ribs 24 are evenly spaced along the circumference of the well shaft 1 between the lower reinforcing ring 2 and the well shaft 1 to ensure that the well shaft 1 is subjected to balanced forces.

[0053] Furthermore, a connecting post 5 is fixedly installed inside the upper reinforcing ring 3, and the bottom end of the connecting post 5 is inserted into the lower reinforcing ring 2 and fixedly connected to the lower reinforcing ring 2.

[0054] The connection strength between the upper reinforcing ring 3 and the lower reinforcing ring 2 is improved, making the connection between the upper reinforcing ring 3 and the lower reinforcing ring 2 more stable, thereby enhancing the overall strength of the well perimeter reinforcing structure.

[0055] Furthermore, such as Figure 2 As shown, a connecting layer 6 is formed between the lower reinforcing ring 2 and the upper reinforcing ring 3. The connecting layer 6 is connected to both the lower reinforcing ring 2 and the upper reinforcing ring 3, which is used to strengthen the connection between the upper reinforcing ring 3 and the lower reinforcing ring 2, improve the connection reliability, and further improve the overall reinforcing structure's anti-settlement effect.

[0056] A method for constructing a perimeter reinforcement structure around a road manhole, comprising:

[0057] Adjustment and reinforcement of well shaft 1: Measure the elevation of the top surface of the lower base course 41 on the completed roadbed to make the elevation of the top surface of well shaft 1 consistent with the elevation of the lower base course 41, and drill holes on the surface of well shaft 1 to insert connecting reinforcement bars 24.

[0058] Only when the top surface level of the shaft 1 is consistent with the level of the lower base layer 41, the shaft 1 can not interfere with the construction of the lower base layer 41, and when adjusting the top surface level of the shaft 1, the shaft 1 can be cut or connected to reduce or increase the height of the top surface of the shaft 1;

[0059] Since the shaft 1 needs to be installed before the construction of the road structure layer and the reinforcing structure, and the level of the shaft 1 needs to be adjusted after the installation of the shaft 1, the installation of the connecting rib 24 can only be performed after the installation of the shaft 1 and the adjustment of the level of the shaft 1 are completed;

[0060] When installing the connecting rib 24, the connecting rib 24 is installed along the circumference of the shaft 1 at equal intervals, and the number of the connecting rib 24 is selected according to the actual situation on site;

[0061] Preferably, in this example, the connecting rib 24 is installed at four positions along the circumference of the shaft 1 at equal intervals by means of the embedded rib on the shaft 1, and the connecting rib 24 at each position is double rows of three ribs.

[0062] Installation of the lower reinforcing ring 2: the prefabricated lower reinforcing ring 2 is sleeved on the shaft 1, so that the top surface level of the lower reinforcing ring 2 is the same as the top surface level of the shaft 1, the lower reinforcing ring 2 is pre-provided with the connecting rib 24, and when the lower reinforcing ring 2 is sleeved, the pre-provided connecting rib 24 in the lower reinforcing ring 2 corresponds to the connecting rib 24 on the shaft 1 one by one, and the opening size of the inner cavity of the lower reinforcing ring 2 is greater than the outer diameter of the shaft 1, so as to form a connecting groove 25 between the inner cavity wall of the lower reinforcing ring 2 and the outer wall surface of the shaft 1;

[0063] The pre-provided connecting rib 24 can increase the connection strength of the connecting rib 24 and the lower reinforcing ring 2;

[0064] Preferably, in this example, the lower reinforcing ring 2 is a circular ring, and the inner cavity diameter of the lower reinforcing ring 2 is greater than the outer diameter of the shaft 1, and when the lower reinforcing ring 2 is installed, the lower reinforcing ring 2 is coaxial with the shaft 1, so that the connecting groove 25 is formed between the inner cavity wall of the lower reinforcing ring 2 and the outer wall surface of the shaft 1;

[0065] Paving and rolling of the lower base layer 41: the clamping block 26 for blocking the lower clamping groove 21 is installed in the lower clamping groove 21, the mixture of the lower base layer 41 is used for paving the lower base layer 41, so that the lower base layer 41 wraps the lower reinforcing ring 2 and the clamping block 26 from the side, and after the lower base layer 41 is formed, the clamping block 26 in the lower clamping groove 21 is removed;

[0066] Since the top surface of the lower reinforcing ring 2 and the top surface of the shaft 1 are the same as the lower base layer 41, when the lower base layer 41 is paved and rolled, the lower reinforcing ring 2 and the shaft 1 will not interfere with the paving and rolling equipment, and the lower base layer 41 can be normally paved and rolled;

[0067] In order to prevent the mixture used in the lower base 41 from entering the lower clamping groove 21, the clamping block 26 is installed in the lower clamping groove 21 in advance, and the lower clamping groove 21 is blocked by the clamping block 26 to prevent the mixture of the lower base 41 from entering the lower clamping groove 21 during paving and rolling of the lower base 41. After the paving and rolling of the lower base 41 is completed, the clamping block 26 is removed from the lower clamping groove 21, and a cavity is formed in the lower clamping groove 21;

[0068] The lower reinforcing ring 2 is horizontally connected by welding the preset connecting rib 24 on the lower reinforcing ring 2 and the connecting rib 24 implanted in the wellbore 1, and pouring concrete in the connecting groove 25 between the lower reinforcing ring 2 and the wellbore 1, and pouring concrete in the original position of the clamping block 26;

[0069] After the installation of the lower reinforcing ring 2 is completed, the connecting rib 24 on the lower reinforcing ring 2 and the connecting rib 24 on the wellbore 1 are still in a separated state. At this time, the connecting rib 24 obviously cannot achieve the effect of connecting the wellbore 1 and the lower reinforcing ring 2. Therefore, the connecting rib 24 implanted in the wellbore 1 and the preset connecting rib 24 in the lower reinforcing ring 2 need to be fixed. In the fixing process, the welding method can be used;

[0070] By pouring concrete in the connecting groove 25, the connecting ring 23 is formed after the concrete is solidified. Similarly, by pouring concrete in the lower clamping groove 21, the first connecting piece 22 is formed after the concrete is solidified;

[0071] The upper reinforcing ring 3 is installed by moving the prefabricated upper reinforcing ring 3 to the lower reinforcing ring 2, and ensuring that the top surface elevation of the upper reinforcing ring 3 is the same as the top surface elevation of the upper base 42;

[0072] The top surface of the lower reinforcing ring 2 is provided with a groove. The connecting layer 6 is formed after the bonding mortar is solidified by filling the bonding mortar in the groove on the top of the lower reinforcing ring 2, and then placing the upper reinforcing ring 3 on the lower reinforcing ring 2. The connecting layer 6 is fixedly connected with the lower reinforcing ring 2 and the upper reinforcing ring 3 at the same time;

[0073] The groove is provided on the top surface of the lower reinforcing ring 2. The thickness and shape of the connecting layer 6 can be controlled through the groove to ensure the stability of the connecting layer 6, and the contact between the upper reinforcing ring 3 and the lower reinforcing ring 2 is not affected, which is more conducive to controlling the height of the upper reinforcing ring 3;

[0074] The lower reinforcing ring 2 is provided with a vertically penetrating lower reserved hole 27, and the upper reinforcing ring 3 is provided with a vertically penetrating upper reserved hole 34. When the upper reinforcing ring 3 is placed, the upper reserved hole 34 provided on the upper reinforcing ring 3 needs to be aligned with the lower reserved hole 27 provided on the lower reinforcing ring 2 to prevent the upper reinforcing ring 3 from being unable to be moved after the bonding mortar is solidified;

[0075] Paving and rolling of the upper base layer 42: The profiled template 35 is attached to the outer side of the upper reinforcing ring 3 to close the upper clamping groove 31, and the mixture of the upper base layer 42 is used to pave the upper base layer 42, so that the upper base layer 42 wraps the outer side of the profiled template 35. After the upper base layer 42 is rolled and formed, the profiled template 35 is removed;

[0076] 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 does not interfere with the paving and rolling equipment when the upper base layer 42 is paved. After the installation of the upper reinforcing ring 3 is completed, the paving work of the upper base layer 42 can be normally carried out, saving the construction process;

[0077] When paving the upper base layer 42, in order to prevent the mixture of the upper base layer 42 from entering the upper clamping groove 31, the profiled template 35 needs to be sleeved on the outer side of the upper reinforcing ring 3 to close the upper clamping groove 31 to prevent the mixture 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 and formed, the profiled template 35 is removed 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;

[0078] Horizontal and vertical connection of the upper reinforcing ring 3: concrete is poured in the position of the original profiled template 35 and the upper clamping groove 31 to form the second connecting piece 32, and concrete is poured in the upper reserved hole 34 and the lower reserved hole 27 to form the connecting column 5;

[0079] By pouring concrete in the position of the original profiled template 35 and 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. After the concrete solidifies, the second connecting piece 32 is formed;

[0080] Installation of the well seat 11: concrete is paved in the installation groove 33 opened at the top of the upper reinforcing ring 3, the hook 12 is buried in the concrete in the installation groove 33, the hook 12 faces the axis of the shaft 1, then the well seat 11 is placed on the concrete in the installation groove 33, the well seat 11 is adjusted to be coaxial with the shaft 1, and the concrete is wrapped outside the bottom of the well seat 11. After the concrete solidifies, the third connecting piece 34 is formed;

[0081] The hook 12 and the well seat 11 are fixed in the installation groove 33 opened at the top of the upper reinforcing ring 3 by the solidification of the concrete;

[0082] Paving and rolling of the surface layer 43: the well cover is installed on the well seat 11, and then the surface layer 43 is paved and rolled;

[0083] The method integrates the construction of the well peripheral reinforcing structure and the construction of the road structure layer by pouring the lower base layer 41 after the lower reinforcing ring 2 is installed, constructing the upper base layer 42 after the upper reinforcing ring 3 is installed, forming the first connecting piece 22 by cooperation of the upper clamping groove 31 and the clamping block 26, and forming the second connecting piece 32 by cooperation of the upper clamping groove 31 and the profiling template 35, saves the overall construction process, greatly improves the construction efficiency, and no longer needs to excavate the well peripheral and fill the concrete, effectively reduces the waste of materials, and is more economical and environmentally friendly.

[0084] As shown in Figure 3 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 the lower base layer 41 is poured, and then after the clamping block 26 is removed, a cavity is formed at the position adjacent to the lower clamping groove 21 and the lower base layer 41, at which time the concrete is poured into the cavity formed by the lower clamping groove 21 and the first base layer to form the first connecting piece 22 having a first part and a second part.

[0085] As shown in Figure 3 the top of the clamping block 26 is provided with a pull ring, so that after the lower base layer 41 is poured, the clamping block 26 can be removed through the pull ring.

[0086] As shown in Figure 5 the profiling template 35 is spliced by multiple parts, so that it is more convenient to remove the profiling template 35 after the upper base layer 42 is poured and rolled.

[0087] As shown in Figure 5 in this example, the upper reinforcing ring 3 is a circular ring, and the inner diameter of the upper reinforcing ring 3 is greater than the inner diameter of the wellbore 1, and when the upper reinforcing ring 3 is installed, the upper reinforcing ring 3 is coaxially arranged with the wellbore 1, and since the inner diameter of the upper reinforcing 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 cavity wall of the upper reinforcing ring 3 to level the inner cavity wall of the wellbore 1, so that the inner cavity wall of the wellbore 1 smoothly transitions to the well seat 11.

[0088] The above only describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
