[0019] In the embodiments of the present application, the words “exemplary” or “for example” are used to mean serving as an example, instance, or illustration. Any embodiment or design presented as “exemplary” or “for example” in the embodiments of the present application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Rather, the use of the words “exemplary” or “for example” is intended to present related concepts in a specific way.

[0020] In order to make the following embodiments clear and simple, a brief introduction of related technologies is given first: Ballastless tracks are widely used in high-speed railways. Among them, the CRTS III slab ballastless track has the characteristics of high smoothness, high reliability, high stability, simple structure, material saving, good durability, high work efficiency, and low maintenance cost, and can be applied to high-speed railways with a speed of 300 kilometers per hour and above.

[0021] However, the CRTS III slab ballastless track has high construction technical difficulty and high construction quality requirement standard at present.

[0022] In order to make the technical solutions of the present application clearer and easier to understand, a construction method of a slab III of a ballastless track provided in an embodiment of the present application is introduced as follows. As shown in the figure, the figure is a flowchart of a construction method of a slab III of a ballastless track provided in an embodiment of the present application. Figure 1

[0023] S101, self-compacting concrete is poured through a reinforced material guide pipe, a first pouring flow rate is obtained, and a first compacting force corresponding to the first pouring flow rate is obtained based on a compacting device. ​

[0024] Among them, the reinforced guide pipe is used to accurately deliver concrete to the area below the track slab; self-compacting concrete is a high-performance concrete with excellent fluidity and self-compacting ability. Therefore, when pouring self-compacting concrete, mechanical vibration is not required. It can fill all the spaces in the formwork and fully wrap the reinforcing bars by its own weight, forming a uniform and dense structure; the first pouring flow rate is the speed at which the self-compacting concrete is poured at the current moment; the clamping device is a device that applies pressure to the track slab to ensure its stable fixation or to meet specific process requirements; the first clamping force is the total clamping force borne by the track slab after the clamping device applies positive pressure to the track slab during the concrete pouring process.

[0025] Optionally, the reinforced feed pipe includes a guide pipe, a supporting steel pipe, and a fastening steel ring; wherein, the fastening steel ring is coaxially sleeved on the outer wall of the guide pipe, and the fastening steel ring is evenly provided with supporting arms along the circumference; the upper end of the supporting steel pipe is connected to the supporting arms by bolts.

[0026] For example, it can be as follows Figure 2 As shown, a vertically arranged guide tube (such as a PVC guide tube) is used to pass through the track slab pouring hole and guide the concrete pouring. A fastening steel ring is coaxially sleeved on the outer wall of the guide tube. Three supporting steel pipes are evenly distributed in a triangle along the circumference of the guide tube, and their upper ends are fixed to the fastening steel ring by bolts. The guide tube is compressed and radially fixed by tightening the adjusting bolts on the fastening steel ring. The extension lines of the three supporting arms pass through the center of the fastening steel ring, and the included angle between any two of the three supporting arms is 120 degrees. The supporting steel pipes and supporting arms are connected by small fastening steel rings and bolts. The connection method can be radial fixation achieved by compression.

[0027] Optionally, a T-junction structure can be installed at the top of the guide pipe, with the bottom of the T-junction approximately 40cm vertically above the top surface of the track slab. Pouring operations can only be stopped once the self-compacting concrete has flowed evenly and continuously from the lateral outlet of the T-junction, ensuring that the lower part of the track slab is fully and densely filled with concrete. The gap between the guide pipe and the track slab pouring hole should be ≤5mm.

[0028] It should be noted that the construction method for Type III ballastless track slabs includes a clamping device; optionally, the clamping device includes a pressure bar beam, a pressure bar locking plate, a spring guide column, a laser sensor, a hydraulic force gauge, a pressure gauge, a lifting screw, a clamping screw, and a base plate clamping column; wherein, the laser sensor collects the upward displacement of the track slab caused by buoyancy; the hydraulic force gauge collects the normal pressure of the pressure bar beam on the track slab; the pressure gauge collects the total pressure borne by the track slab; the lifting screw realizes the extension and retraction function of the pressure bar beam; the clamping screw realizes the extension and retraction function of the pressure bar locking plate; the clamping device adjusts the clamping force based on the upward displacement, normal pressure, and pressure.

[0029] Optionally, the compacting device collects the total pressure borne by the floating displacement and the track plate in real time, and calculates the value of the positive pressure required to be applied to the track plate in the case of floating displacement > 0.3mm or total pressure < 10kN; then the latest value of the positive pressure applied to the track plate can be calculated to adjust the lifting screw to compensate for the pressure increase or pressure reduction of the track plate, so as to prevent the track plate from floating or deviating during the pouring process, and even cause the track plate to crack and the base plate to be damaged. Especially in the process of curve segment construction, if the high side pressure is too large, the track plate on the low side will be warped, forming unilateral voids, and if the low side pressure is too small, the concrete will flow out from the low side, polluting the base and weakening the support. The compacting device in the embodiment can control the two sides separately in the curve segment.

[0030] S102, based on the first pouring flow rate, determine the sample pouring flow rate corresponding to the first pouring flow rate, and the pressure time data set corresponding to the sample pouring flow rate.

[0031] Among them, the sample pouring flow rate is close to the first pouring flow rate; the pressure time data set is the corresponding relationship between the total pressure borne by the track plate and the time under the sample pouring flow rate.

[0032] Optionally, the sample pouring flow rate includes a first sample pouring flow rate and a second sample pouring flow rate, and the pressure time data set includes a first pressure time data set corresponding to the first sample pouring flow rate and a second pressure time data set corresponding to the second sample pouring flow rate, the end time of the first pressure time data set is the first end time, and the end time of the second pressure time data set is the second end time, the first end time is less than the second end time.

[0033] S103, based on the first pouring flow rate and the pressure time data set corresponding to the sample pouring flow rate, predict the predicted pressure of the first pouring flow rate.

[0034] Among them, the predicted pressure is the predicted pressure value of the track plate under the first pouring flow rate.

[0035] One implementation, based on the first sample pouring flow rate and the first pressure time data set, the relationship between time and pressure is fitted to obtain the first fitting curve; the pressure corresponding to the second end time in the first fitting curve is determined as the fitting pressure, and the pressure corresponding to the second end time in the second pressure time data set is determined as the second pressure; based on the fitting pressure, the second pressure and the first pouring flow rate, the predicted pressure corresponding to the first pouring flow rate is determined.

[0036] The first fitting curve can represent a dynamic relationship between the compacting force applied to the track slab at the first sample pouring speed and time; and the fitting compacting force can represent an estimated compacting force applied to the track slab at the second end time at the first sample pouring speed.

[0037] Optionally, based on the fitting compacting force, the second compacting force, and the first pouring flow rate, a predicted compacting force corresponding to the first pouring flow rate is determined, and the specific steps can include: Based on the difference between the first pouring flow rate and the first sample pouring flow rate, a first difference weight is determined; based on the difference between the first pouring flow rate and the second sample pouring flow rate, a second difference weight is determined; and based on the fitting compacting force, the second compacting force, the first difference weight, and the second difference weight, a predicted compacting force corresponding to the first pouring flow rate is determined.

[0038] For example, according to a pre-set mapping relationship between the flow rate difference and the weight (the mapping relationship satisfies the core logic that "the smaller the difference, the greater the weight"); and then, based on the pre-set mapping relationship, the first difference weight corresponding to the difference between the first pouring flow rate and the first sample pouring flow rate, and the second difference weight corresponding to the difference between the first pouring flow rate and the second sample pouring flow rate can be determined.

[0039] For example, when the difference d1 between the first pouring flow rate and the first sample pouring flow rate is 0, the first difference weight w1 is 1 (completely trust the sample); when the difference d1 between the first pouring flow rate and the first sample pouring flow rate increases, the first difference weight w1 is reduced in proportion.

[0040] Optionally, the product of the fitting compacting force and the first difference weight can be determined as the first predicted compacting force; the product of the second compacting force and the second difference weight can be determined as the second predicted compacting force; and the sum of the first predicted compacting force and the second predicted compacting force can be determined as the predicted compacting force corresponding to the first pouring flow rate.

[0041] S104, control the pouring flow rate based on the first compacting force and the predicted compacting force.

[0042] In one implementation, the ratio of the first compacting force and the predicted compacting force is determined as a first ratio; and in the case that the first ratio is greater than or equal to a pre-set compacting force ratio, the pouring flow rate is adjusted to half of the first pouring flow rate.

[0043] The first ratio can be used to judge the deviation between the actual state and the theoretical state, i.e., the deviation between the current compacting force and the theoretical compacting force corresponding to the current pouring flow rate.

[0044] Optionally, the pre-set compacting force ratio can represent the maximum deviation threshold allowed by the process (such as 0.95, which can be set according to the equipment carrying capacity or product quality standard).

[0045] For example, when the first ratio is less than the preset compacting force ratio, it is determined that the state is normal: the current first pouring flow rate is maintained unchanged, and the monitoring continues; when the first ratio is greater than or equal to the preset compacting force ratio, it is determined that the state is abnormal: immediate adjustment is performed, and the new flow rate is adjusted to half of the current flow rate.

[0046] Optionally, a minimum safety flow rate limit can also be set, that is, by setting a minimum pouring flow rate, pouring interruption caused by excessively low flow rate can be avoided; if the adjusted flow rate is less than the minimum pouring flow rate, an audible and visual alarm (manual intervention prompt) can be given The above-mentioned construction method of the No. III type slab of the ballastless track can provide data for subsequent adjustment of the pouring flow rate by reinforcing the guide pipe for pouring the self-compacting concrete, obtaining the first pouring flow rate, and obtaining the first compacting force corresponding to the first pouring flow rate based on the compacting device. Further, the first pouring flow rate corresponding sample pouring flow rate and the compacting force-time data set corresponding to the sample pouring flow rate can be determined based on the first pouring flow rate. Then, the predicted compacting force corresponding to the first pouring flow rate can be predicted based on the compacting force-time data set corresponding to the first pouring flow rate and the sample pouring flow rate, which provides a basis for judging whether the pouring flow rate needs to be controlled. Then, the pouring flow rate can be controlled based on the first compacting force and the predicted compacting force. The present scheme provides a judgment basis for determining whether the first pouring flow rate is reasonable by introducing the sample pouring flow rate and the compacting force-time data set. Furthermore, the predicted compacting force is introduced to provide a specific direction for adjusting the pouring flow rate, thereby ensuring the quality of construction.

[0047] On the basis of the above-mentioned embodiments, the base plate force transmission gasket construction device in the embodiments of the present application comprises a positioning steel plate, a compacting steel plate, a square steel pipe, a connecting lug plate and a G-shaped bolt.

[0048] The positioning steel plate is welded on one side of the square steel pipe, the force transmission gasket is laid along the positioning steel plate, the compacting steel plate is placed on the side of the force transmission gasket close to the square steel pipe, and is used for pressing the force transmission gasket on the positioning steel plate; the connecting lug plate is welded on the compacting steel plate; and the G-shaped bolt fastens and connects the compacting steel plate and the square steel pipe through the connecting lug plate.

[0049] For example, as shown in FIG. 6, the compacting force-time data set corresponding to the first pouring flow rate is obtained, and the predicted compacting force corresponding to the first pouring flow rate is predicted based on the compacting force-time data set corresponding to the first pouring flow rate and the sample pouring flow rate. Figure 3As shown, taking the construction of the force transmission pad of the 2900mm wide base plate as an example, the base plate thickness is 200mm, and the force transmission pad size is 20mm*220mm*3100mm. The base plate force transmission pad construction device includes a positioning steel plate with a size of 5mm (thick)*320mm (wide)*3100mm, a square steel pipe with a size of 40mm*40mm*3200mm (cross section*length), a pressing steel plate with a size of 20mm (thick)*40mm (wide)*3100mm, and a connecting ear plate with a size of 20mm*150mm*40mm. The positioning steel plate is welded to one side of the square steel pipe, and then the force transmission pad is laid flat along the positioning steel plate. On the other side of the force transmission pad, the force transmission pad is compacted on the positioning steel plate using the pressing steel plate, the positioning steel plate is coated with lubricating grease on both sides, and three connecting ear plates are welded on the pressing steel plate. Among them, the pressing mode is that the connecting ear plates are tightly connected with the square steel pipe through three G-shaped bolts.

[0050] Optionally, as shown, Figure 4 The spacing between the front and rear base plate forms can be 20mm, and the edge of the form is sealed with a 20mm thick steel plate.

[0051] It should be noted that after the concrete is poured, the base plate force transmission pad construction device can be disassembled, such as removing the three G-shaped bolts and the pressing steel plate and the positioning steel plate, holding one end of the square steel pipe, and pulling out the pressing steel plate from the concrete. After the concrete is removed from the form, the force transmission pad exposed to the concrete is cut off.

[0052] In the embodiments of the present application, the structure of the pressing steel plate and the positioning steel plate cooperates to achieve the preliminary flattening of the force transmission pad in the direction perpendicular to the base plate. In addition, by inserting a sealing steel plate between the forms on both sides of the same end of the force transmission pad, the forms on both sides of the same end of the force transmission pad abut against the sealing steel plate, so as to further tension the two exposed ends of the force transmission pad, and the flatness of the force transmission pad in the entire plane is achieved, avoiding the occurrence of wrinkles and the problem of cracks caused by the connection of the two ends of the concrete, improving the service life of the force transmission pad, and greatly improving the waterproof sealing function of the force transmission pad.

[0053] On the basis of the above-mentioned embodiments, the present application relates to a tool for rough paving of a track plate, which is threadedly connected at both ends, one end of which can be connected with an object beside the track, and the other end of which is located at the track plate positioning line position of the base plate.

[0054] Exemplarily, as shown, Figure 5As shown, the two ends of the tool can be connected by threads, one end can be hooked with the wall of the ditch or cable slot or protective wall beside the track to achieve positioning, and the other end can be directly seated on the base plate at the position of the positioning line of the track plate, and then the length of the two ends of the tool can be directly adjusted by threads to achieve accurate positioning.

[0055] For example, in the process of hoisting the track plate, one end of the track plate can be tightly attached to one side of the tool before falling down, thereby improving the accuracy of the rough paving of the track plate to within 1 centimeter.

[0056] In the embodiment of the present application, by introducing the tool, the rough paving accuracy is improved while the construction speed is improved.
