The outer formwork truss 130 may include outer formwork supports 133 and outer templates, with the outer formwork supports 133 connected to the outside of the outer templates. The bottom ends of the inner formwork trusses 230 on both sides can be connected to the end faces on both sides of the inner vehicle floor 210.

[0048] The culvert full-section construction trolley of this embodiment can be used in the following steps:

[0049] Step S11: As Figure 1 As shown, the culvert full-section construction trolley is moved to the place where concrete is to be poured. At this time, the position of the inner formwork mechanism can be adjusted by moving the inner car moving mechanism 220 so that the inner formwork mechanism is located inside the outer formwork mechanism. Concrete is poured between the outer formwork mechanism and the inner formwork mechanism to form a culvert including the two side walls 300 and the top plate 400.

[0050] Step S12, as follows Figure 2 and Figure 3 As shown, the inner mold trusses 230 and the top plate inner trusses 240 on both sides are driven to rotate in opposite directions by the inner mold rotation mechanism 250, causing the inner mold trusses 230 and the top plate inner trusses 240 on both sides to retract inward, thereby causing the inner mold mechanism as a whole to detach from the inner surface of the concrete-poured culvert; at this time, it can be as follows Figure 6 As shown, the retracted inner mold mechanism is first pushed out of the culvert by the inner car moving mechanism 220;

[0051] Specifically, first rotate the lower part of the inner mold truss 230 inward to make the inner mold truss 230 shrink, and then rotate the inner side of the top plate inner truss 240 inward to make the top plate inner truss 240 shrink again.

[0056] Step S21, as shown, the retracted inner mold mechanism is first pushed to the next culvert construction site by the inner trolley moving mechanism 220, and then as shown, the two-sided inner mold truss 230 and the two-sided top plate inner truss 240 are reassembled to form the initial state of the inner mold mechanism. Figure 8 Figure 9 Step S22, the two-sided outer mold truss 130 and the top plate outer truss 140 are reassembled to form the outer mold mechanism, and as shown, the outer mold mechanism is pushed to the outside of the inner mold mechanism position.

[0058] Step S23, as shown, the above steps S11 to S14 are repeated. Figure 11

[0059] In some embodiments, in order to facilitate the movement of the inner mold mechanism by the inner trolley moving mechanism 220, the inner trolley moving mechanism 220 is arranged on the inner trolley track 221.

[0060] In the above steps S2 or S4, the inner mold mechanism separated from the inner surface of the culvert can be moved out of the culvert by the inner trolley moving mechanism 220 on the inner trolley track 221.

[0061] In order to facilitate the movement of the inner mold mechanism by the inner trolley moving mechanism 220 inside the outer trolley, the inner trolley track 221 is arranged on the outer trolley bottom plate 110.

[0062] In order to facilitate the smooth movement of the inner trolley moving mechanism 220 on the inner trolley track 221, reduce the moving friction resistance, the inner trolley track 221 can be protruded from the outer trolley bottom plate 110. For example, the inner trolley track 221 can be an I-beam arranged on the outer trolley bottom plate 110.

[0063] In order to facilitate the manufacture and installation of the inner trolley moving mechanism 220, the inner trolley moving mechanism 220 can be an inner trolley walking wheel arranged on the inner trolley track 221. ​​​

[0064] In order to prevent the inner car walking wheel from deviating when moving, inner wheel anti-deviation limiting blocks 222 can be arranged on both sides.

The top ends of the inner wheel anti-deviation limiting blocks 222 on both sides can be connected to the two sides of the inner wheel top limiting plate.

[0065] In order to improve the balance and stability of the inner car moving mechanism 220, the inner car walking wheel is at least four, and the four inner car walking wheels are distributed in a rectangular shape at the four corners of the bottom of the inner car bottom plate 210. At this time, the inner car track 221 is two, and is parallel to each other, and the inner car walking wheels on both sides are arranged on the two inner car tracks 221 and move along the inner car tracks 221.

[0066] In order to improve the stability of the inner car walking wheel moving on the inner car track 221, grooves are arranged on the inner car track 221, the inner car walking wheel is arranged in the groove and moves along the length direction of the groove. The grooves on the two inner car tracks 221 are parallel to each other.

[0067] In order to improve the firmness and stability of the overall support structure of the inner side, the inner car bottom plate 210 can be an inner car bottom truss structure, that is, the inner car bottom plate 210 can be connected by welding a plurality of steel bars to form a bottom truss.

[0068] In order to facilitate the movement of the outer car part, the outer car frame further includes an outer car moving mechanism 120, and the outer car moving mechanism 120 is installed at the bottom of the outer car bottom plate 110.

[0069] In order to facilitate the manufacture and installation of the outer car moving mechanism 120, the outer car moving mechanism 120 can be an outer car walking wheel. The outer car walking wheel can be arranged on the outer car track 121. The outer car track 121 can be an I-beam. The outer car track 121 can also be arranged on the outer support plate 123 to improve the support firmness of the overall table car. The outer support plate 123 can be a steel plate.

[0070] In order to prevent the outer car walking wheel from deviating when moving, outer wheel anti-deviation limiting blocks 122 can be arranged on both sides. Specifically, shaft holes can be formed on the outer wheel anti-deviation limiting blocks 122 on both sides, the two ends of the outer car wheel shaft are connected to the outer wheel anti-deviation limiting blocks 122 on both sides, and the outer car walking wheel is rotatably installed on the outer car wheel shaft. The top ends of the outer wheel anti-deviation limiting blocks 122 on both sides can be connected to the two sides of the outer wheel top limiting plate.

[0071] In order to improve the balance stability of the outer vehicle moving mechanism 120, the outer vehicle walking wheels can be at least four, and the four outer vehicle walking wheels are distributed in a rectangular shape at the four corners of the bottom of the outer vehicle bottom plate 110. At this time, the outer vehicle track 121 can be two, and the outer vehicle walking wheels on both sides are arranged on the two outer vehicle tracks 121 and move along the outer vehicle track 121.

[0072] In order to improve the stability of the outer vehicle walking wheels moving on the outer vehicle track 121, grooves can also be arranged on the outer vehicle track 121, and the outer vehicle walking wheels are arranged in the grooves and move along the length direction of the grooves. The grooves on the two outer vehicle tracks 121 are parallel to each other.

[0073] The bottom ends of the two outer mold trusses 130 can be connected to the top surfaces of the two sides of the outer vehicle bottom plate 110, respectively.

[0074] In some embodiments, in order to facilitate the inner mold dismounting mechanism to drive the inner mold truss 230 and the top plate inner truss 240 to shrink, improve the efficiency of the inner mold mechanism to shrink and separate from the inner surface of the tunnel, the inner mold dismounting mechanism is a combination of two inclined hydraulic rods 260, or two inner mold jacks 262 and two top plate jacks 261, or a combination of two inclined hydraulic rods 260 and two inner mold jacks 262, or a combination of two inclined hydraulic rods 260 and two top plate jacks 261.

[0075] Among them, the two ends of the inclined hydraulic rod 260 are respectively connected to the middle or upper part of the inner mold truss 230 and the middle or inner side of the top plate inner truss 240.

[0076] The inner mold jack 262 is arranged between the middle or lower part of the inner mold truss 230 and the wall 300; at the same time, the inner mold jack 262 can also be arranged in the middle or lower part of the wall 300, for example, the fixed end of the inner mold jack 262 is fixedly connected to the inner mold truss 230, and the telescopic driving end contacts the middle or lower part of the wall; or the fixed end of the inner mold jack 262 is fixedly connected to the middle or lower part of the wall 300, and the telescopic driving end contacts the middle or lower part of the inner mold truss 230.

[0077] The top plate jack 261 is arranged between the inner side or middle part of the top plate inner truss 240 and the top plate 400; at the same time, the top plate jack 261 can also be arranged in the middle part of the top plate 400, for example, the fixed end of the top plate jack 261 is fixedly connected to the middle part of the wall top plate 400, and the telescopic driving end contacts the inner side or middle part of the top plate inner truss 240.

[0078] In the above step S2, the inclined hydraulic rod 260 can be used to shrink, so that the two sides of the inner mold truss 230 and the two sides of the top plate inner truss 240 rotate and shrink towards the inner side, so that the inner mold mechanism as a whole separates from the inner surface of the tunnel for concrete pouring.

[0079] Alternatively, the inner mold mechanism can be driven to detach from the inner surface of the concrete-poured culvert as a whole by driving the lower part of the inner mold truss 230 to rotate and contract inwards through the telescopic driving end of the inner mold jack 262, and driving the inner side of the inner truss 240 of the top plate to rotate and contract inwards towards each other through the telescopic driving end of the top plate jack 261.

[0080] Alternatively, the inner mold mechanism can be driven to detach from the inner surface of the concrete-poured culvert as a whole by driving the lower part of the inner mold truss 230 to rotate and contract inwards through the telescopic driving end of the inner mold jack 262, or driving the inner side of the inner truss 240 of the top plate to rotate and contract inwards towards each other through the telescopic driving end of the top plate jack 261, or driving the lower part of the inner mold truss 230 and the inner side of the inner truss 240 of the top plate to rotate and contract inwards through the telescopic driving end of the inner mold jack 262 and the top plate jack 261 in combination.

[0081] In order to facilitate the expansion of the outer mold truss 130 driven by the outer mold dismounting mechanism, the outer mold dismounting mechanism is an outer mold jack, which is arranged between the upper part of the outer mold truss 130 and the wall body 300. At this time, the outer mold jack can also be arranged on the upper part of the wall body 300. For example, the fixed end of the outer mold jack is fixedly connected to the upper part of the wall body 300, and the telescopic driving end contacts the upper part of the outer mold truss 130.

[0082] In the above step S3, the upper part of the outer mold truss 130 can be driven to tilt and expand outwards through the telescopic driving end of the outer mold jack, so that the outer mold mechanism detaches from the outer surface of the concrete-poured culvert as a whole.

[0083] In some embodiments, in order to optimize the structure of the inner mold mechanism and make the inner mold mechanism more conducive to contraction, the two-sided inner mold dismounting mechanism includes two-sided inclined hydraulic rods 260 and a middle transverse hydraulic rod 263, the two ends of the inclined hydraulic rods 260 are respectively connected to the upper part of the inner mold truss 230 and the inner side of the inner truss 240 of the top plate, and the inner ends of the two-sided inclined hydraulic rods 260 are respectively connected to the two ends of the transverse hydraulic rod 263; an inner mold angle bracket 270 is arranged between the inner mold truss 230 and the inner truss 240 of the top plate, and the two sides of the inner mold angle bracket 270 are respectively rotatably connected to the inner mold truss 230 and the inner truss 240 of the top plate through the inner mold rotating mechanisms 250; and the inner mold rotating mechanisms 250 are bearing pieces.

[0084] In the above step S2, specifically, one inner mold rotating mechanism 250 can be used to drive the lower part of the inner mold truss 230 to rotate inwards through the inclined hydraulic rod 260, so as to realize the contraction of the inner mold truss 230; and another inner mold rotating mechanism 250 can be used to drive the inner side of the inner truss 240 of the top plate to rotate inwards through the inclined hydraulic rod 260, so as to realize the contraction of the inner truss 240 of the top plate; for example, Figure 4As shown, the inner mold mechanism can be further contracted by tilting the hydraulic rod 260 to drive the inner mold angle frame 270 on both sides to move inwardly to contract, so as to realize the effective contraction of the whole inner mold mechanism. At this time, the whole inner mold mechanism can be promoted to sink downward by the top plate jack 261.

[0085] In order to strengthen the support strength of the inner car part, thereby improving the support strength of the whole trolley, as shown in the figure, Figure 5 As shown, the inner support plate 223 can be arranged below the inner car part. The inner support plate 223 can be a horizontal steel plate, which can be arranged below the inner car moving mechanism 220 for supporting the inner car moving mechanism 220.

[0086] For example, the inner support plate 223 can be arranged below the inner car walking wheel, the inner car walking wheel is in contact with the top surface of the inner support plate 223, and the inner support plate 223 supports the inner car walking wheel.

[0087] The vertical center symmetry axes of the inner car moving mechanism 220 and the inner support plate 223 can coincide.

[0088] In order to further ensure the support firmness and stability of the inner car part, thereby further ensuring the support firmness and stability of the whole trolley, as shown in the figure, Figure 5 As shown, the inner support frame 224 can be arranged below the inner support plate 223. The inner support frame 224 can be arranged below the inner support plate 223, and the top surface of the inner support frame 224 is in contact with the bottom surface of the inner support plate 223 to support the inner support plate 223, thereby strengthening the support of the inner car part and the support of the whole trolley.

[0089] The inner support frame 224 can be a trapezoidal frame, which can be composed of a plurality of steel bars. The number of inner support frames 224 can be two, and they are symmetrically distributed. The vertical center symmetry axes of the inner car moving mechanism 220 and the two inner support frames 224 can coincide. Alternatively, the two inner support frames 224 can be arranged at the bottom of the inner car walking wheel on both sides of the inner car moving mechanism 220.

[0090] In order to facilitate the rotary connection of the inner mold angle frame 270 with the inner mold truss 230 and the inner truss 240 of the top plate, the two ends of the inner mold angle frame 270 are respectively connected with the top end of the inner mold truss 230 and the outer end of the inner truss 240 of the top plate through the inner mold rotary mechanism 250 such as bearing.

[0091] In addition, the inner mold angle frame 270 can be an inclined structure, and the inner mold angle frames 270 on both sides can be inclined to form a figure-of-eight structure, so as to facilitate the rotary connection of the inner mold angle frame 270 with the inner mold truss 230 and the inner truss 240 of the top plate, and also facilitate the matching of the inclined chamfer structure at the top corner of the tunnel.

[0092] In order to facilitate the rotational movement of the inner mold angle frame 270, the inner mold truss 230 and the inner roof truss 240, the inner mold angle frame 270 can be a pentagonal frame body, and the two ends of the bottom side are respectively connected to the top end of the inner mold truss 230 and the outer end of the inner roof truss 240 through the inner mold rotating mechanism 250.

[0093] In some embodiments, in order to facilitate the outward tilting expansion of the outer mold truss 130 on both sides, a roller 131 is arranged on the outer mold truss 130 on both sides, and the roller 131 is in contact with the bottom surface of the outer roof truss 140. When the outer mold truss 130 tilts outward, the rolling of the roller 131 can avoid direct contact and friction between the top end of the outer mold truss 130 and the bottom surface of the outer roof truss 140, thereby improving safety and service life.

[0094] In order to facilitate the installation of the roller 131, an installation plate 132 extending inwardly and laterally can be connected to the outer mold truss 130 on both sides, and the roller 131 is installed on the top surface of the installation plate 132.

[0095] Specifically, the outer end of the installation plate 132 is connected to the top end of the outer mold truss 130.

[0096] At least two rollers 131 can be installed on each installation plate 132, and the plurality of rollers 131 can be uniformly distributed.

[0097] In some embodiments, in order to simultaneously push the outer mold mechanism and the inner mold mechanism out of the tunnel while maintaining the firm stability of the outer mold mechanism and the inner mold mechanism and improving the safety of use, a support frame is arranged between the outer vehicle part and the inner vehicle part; the support frame is composed of a plurality of steel bars to form a mesh frame structure.

[0098] The steel bars that form the support frame can be connected by welding, and can include horizontal, vertical and diagonal steel bars.

[0099] In the above step S4, the support frame can be first moved and placed between the outer vehicle part and the inner vehicle part, so that the support frame is located between the outer mold mechanism and the inner mold mechanism, and then the inner mold mechanism separated from the inner surface of the tunnel can be pushed out of the tunnel at the same time as the outer mold mechanism separated from the outer surface of the tunnel.

[0100] In order to ensure the firm stability of the support frame, the support frame can include side support frames on both sides and a top support frame on the top, and the two ends of the top support frame can be respectively connected to the top ends of the side support frames. The side support frames on both sides can be respectively located between the outer mold truss 130 and the inner mold truss 230 on both sides, and the top support frame can be located between the outer roof truss 140 and the inner roof truss 240.

[0101] The outer mold mechanism can be a rectangular frame composed of the outer mold trusses 130 on both sides and the top plate outer truss 140 on the top, the inner mold mechanism can be a rectangular frame composed of the inner mold trusses 230 on both sides and the top plate inner truss 240 on the top, and the support frame can be a rectangular frame composed of the side support frames on both sides and the top support frame on the top.

[0102] The top plate outer truss 140 and the top plate inner truss 240 can each be a transverse truss structure as shown in FIG. 2. Figure 13 The top plate inner trusses 240 on both sides are arranged transversely side by side, and in general, the transverse span of the top plate outer truss 140 is greater than the sum of the transverse spans of the top plate inner trusses 240 on both sides.

[0103] Embodiment 2

[0104] A full-face construction method of a culvert, comprising the following steps:

[0105] Step S01: pouring concrete between the outer mold mechanism and the inner mold mechanism to form a culvert including the side walls 300 and the top plate 400 on the top;

[0106] Step S02: retracting the inner mold mechanism so that the inner mold mechanism as a whole is separated from the inner surface of the culvert formed by pouring concrete;

[0107] Step S03: expanding the outer mold mechanism so that the outer mold mechanism as a whole is separated from the outer surface of the culvert formed by pouring concrete;

[0108] Step S04: pushing the inner mold mechanism and the outer mold mechanism out of the culvert to a position away from the culvert.

[0109] Further, in step S02, if the span of the top plate inner truss 240 of the inner mold mechanism is greater than a preset value, after the inner mold mechanism as a whole is separated from the inner surface of the culvert formed by pouring concrete, a vertical support structure 280 is arranged inside the culvert as shown in FIG. 4, so that the top end of the support structure 280 contacts and supports the top of the culvert. Figure 13 Figure 12 Further, in step S02, if the span of the top plate inner truss 240 of the inner mold mechanism is greater than a preset value, after the inner mold mechanism as a whole is separated from the inner surface of the culvert formed by pouring concrete, a vertical support structure 280 is arranged inside the culvert as shown in FIG. 4, so that the top end of the support structure 280 contacts and supports the top of the culvert.

[0110] Here, the span of the top plate inner truss 240 of the inner mold mechanism being greater than a preset value means that the transverse width of the top plate inner truss 240 is greater than a preset value, and the preset value can be 10 m.

[0111] At this time, the telescopic driving end of the top plate jack 261 fixed on the top plate 400 can be in contact with the top end of the support structure 280, so as to facilitate the installation or disassembly of the support structure 280 through the telescopic driving of the top plate jack 261.

[0112] Further, in step S04, a support frame can be arranged between the outer mold mechanism and the inner mold mechanism, and then the inner mold mechanism and the outer mold mechanism are pushed out of the culvert to a position away from the culvert. ​

[0113] The culvert full-face construction method of embodiment 2 can be implemented by the culvert full-face construction trolley of embodiment 1.

[0114] The above merely provides an example of the present application, but is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application should be included in the scope of claims of the present application.
