Description
Technical Field
[0001] This utility model relates to the technical field of high-speed railway concrete filling equipment, and in particular to an auxiliary device for preventing overflow of self-compacting concrete filling under high-speed railway track slabs. Background Art
[0002] like Figure 1 As shown, high-speed railway tracks have a base slab, on which track slabs are laid. Self-compacting concrete needs to be poured between the track slabs and the base slab. Figure 8 As shown, the existing technology involves creating filling holes and observation holes at intervals on the track slab, with an observation hole on each side of the filling hole. Self-compacting concrete is poured between the track slab and the base plate through a filling overflow prevention pipe installed on the filling hole. The state of the self-compacting concrete being poured between the track slab and the base plate is observed through the observation holes during the pouring process.
[0003] However, due to the lack of support for the overflow prevention pipe, it is easy to tilt or be pushed out, resulting in the column above being tilted after the pouring is completed, causing the product to not meet the requirements. After the overflow prevention pipe is pushed out, it is easy to cause contamination of the slab surface during the pouring process, increasing the subsequent contamination surface treatment process and wasting construction resources. Summary of the Invention

The CRTSⅢ type slab track of high-speed railway has a base plate at its lower part, and a track slab above the base plate. The track slab has a grouting hole. The anti-overflow pipe auxiliary device includes an anti-overflow pipe, the lower end of which is inserted into the grouting hole; a support frame, disposed on the upper surface of the track slab, including a support ring, through which the lower part of the anti-overflow pipe passes and is inserted into the grouting hole; and three or more support feet, disposed outside the support ring and in contact with the upper surface of the track slab, stably supporting the support ring.

[0007] As a further improvement of this application, an arc-shaped support plate is provided on one end of the first locking bolt that is inserted into the support ring. The support plate is movably connected to the end of the first locking bolt and has a degree of freedom to swing around the end of the first locking bolt in the horizontal direction.
[0008] As a further improvement of this application, a sleeve is fitted onto the end of the first locking bolt, and the support plate is movably connected to the sleeve by a pin, the pin being perpendicular to the horizontal plane.

[0010] As a further improvement of this application, the transverse rod is a telescopic rod, which changes its length by telescoping, thereby adjusting the contact position between the lower surface of the longitudinal rod and the upper surface of the track plate.
[0011] As a further improvement of this application, the transverse rod includes an outer tube, an inner tube inserted into the outer tube, and a limiting pin; the outer tube and the inner tube are each provided with a plurality of limiting holes; the axis of the limiting hole is perpendicular to the horizontal plane; the length of the adjusted transverse rod is limited by inserting the limiting hole that coincides with the outer tube and the inner tube.
[0012] As a further improvement of this application, the number of limiting holes on both the outer tube and the inner tube is more than one; the distance between adjacent limiting holes on the outer tube is ten millimeters, and the distance between adjacent limiting holes on the inner tube is nine millimeters.
[0013] As a further improvement of this application, the filling anti-overflow pipe includes a main pipe and an auxiliary pipe sleeved on the lower end of the main pipe; the auxiliary pipe is made of a soft material.
[0014] The beneficial effects of this utility model are as follows: The support frame ensures the filling overflow pipe remains vertical.

DETAILED DESCRIPTION
[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0028] like Figure 2 and Figure 3 As shown, an auxiliary device for preventing overflow of self-compacting concrete under a high-speed railway track slab is disclosed. The CRTSⅢ type slab track of a high-speed railway has a base plate at the bottom and a track slab above it. The track slab has a grouting hole. The auxiliary device includes a grouting overflow pipe 1, the lower end of which is inserted into the grouting hole; a support frame 2, disposed on the upper surface of the track slab, including a support ring 21, the lower part of which passes through the support ring 21 and is inserted into the grouting hole; and three or more support feet 22, disposed outside the support ring 21, contacting the upper surface of the track slab to stably support the support ring 21.
[0029] Supported by the support frame 2, the filling overflow pipe 1 remains vertical. After the concrete solidifies, the upper column remains vertical, effectively solving the problem of the filling overflow pipe 1 lacking support and easily tilting. Furthermore, the filling overflow pipe 1 is difficult to push out under the action of the support frame 2.
[0030] To ensure a tight fit, the support ring 21 is also provided with a locking hole 23 on its side. A first locking bolt 24 is provided in the locking hole, and an internal thread that mates with the external thread of the first locking bolt 24 is provided in the locking hole 23. The first locking bolt 24 presses against the outer wall of the filling anti-overflow tube 1 to maintain the state of the filling anti-overflow tube 1 and prevent the filling anti-overflow tube 1 from tilting due to loose fit or gaps.
[0031] like Figure 3As shown, in order to increase the contact area and protect the filling overflow tube 1, an arc-shaped support plate 25 is provided on one end of the first locking bolt 24 that is inserted into the support ring 21. The support plate 25 is movably connected to the end of the first locking bolt 24, and the support plate 25 has the freedom to swing around the end of the first locking bolt 24 in the horizontal direction.
[0032] like Figure 4 and Figure 5 As shown, to ensure that the support plate 25 remains horizontal regardless of the rotation of the first locking bolt 24 and its eventual stop position, a sleeve 26 is fitted onto the end of the first locking bolt 24. The support plate 25 and the sleeve 26 are movably connected by a pin, which is perpendicular to the horizontal plane. The connection between the end of the first locking bolt 24 and the sleeve 26 prevents the rotational movement of the first locking bolt 24 from being transmitted to the support plate 25, thus keeping the support plate 25 horizontal and ensuring good contact with the outer wall of the filling overflow tube 1.
[0033] To accommodate the unevenness of the track surface, the support foot 22 includes a transverse rod 221, one end of which is fixed to the outer wall of the support ring 21; a longitudinal adjustment ring 222, located at the free end of the transverse rod 221, with its axis perpendicular to the horizontal plane; a positioning adjustment hole on the side of the longitudinal adjustment ring 222, with a second locking bolt 223 inside the positioning adjustment hole, and an internal thread that mates with the external thread of the second locking bolt 223; and a longitudinal rod 224, inserted into the longitudinal adjustment ring 222, held in place by the second locking bolt 223 on its side, with its bottom contacting the upper surface of the track plate.
[0034] By adjusting the position of the longitudinal rod 224, the unevenness of the track plate surface is adapted to keep the support ring 21 horizontal.
[0035] To further increase adaptability, certain sections of the track slab are avoided, such as... Figure 6 As shown, the transverse rod 221 is a telescopic rod, which changes its length by telescoping, thereby adjusting the contact position between the lower surface of the longitudinal rod 224 and the upper surface of the track plate.
[0036] To achieve telescopic extension, the transverse rod 221 includes an outer tube 2211, an inner tube 2212 inserted into the outer tube 2211, and a limiting pin 2213; the outer tube 2211 and the inner tube 2212 are each provided with a plurality of limiting holes 2214; the axis of the limiting hole 2214 is perpendicular to the horizontal plane; the limiting pin 2213 limits the overall length of the adjusted transverse rod 221 by inserting into the limiting hole 2214 that coincides with the outer tube 2211 and the inner tube 2212.
[0037] To increase the adjustment range, both the outer tube 2211 and the inner tube 2212 have at least three limiting holes 2214. The distance between adjacent limiting holes 2214 on the outer tube 2211 is ten millimeters, and the distance between adjacent limiting holes 2214 on the inner tube 2212 is nine millimeters. This ensures that even if the adjusted distance is not the distance between adjacent limiting holes 2214, both the outer tube 2211 and the inner tube 2212 have overlapping limiting holes 2214 for the insertion of the limiting pin 2213.
[0038] like Figure 7 As shown, to facilitate insertion and final removal, the filling overflow prevention pipe 1 includes a main pipe 11 and an auxiliary pipe 12 sleeved on the lower end of the main pipe 11; the auxiliary pipe 12 is made of a soft material. The upper surface of the self-compacting concrete is kept inside the auxiliary pipe 12, and when finally removing the auxiliary pipe 12, its elasticity makes it easy to pull out without shaking it.
