Description

Technical Field

[0001] The invention relates to the technical field of equipment and construction methods for earth-rock dam construction, in particular to equipment and a construction method for a reinforced core wall of an earth-rock dam. Background Art

[0002] Earth-rock dams are widely used due to their strong adaptability to geological and topographical conditions, easy availability of dam-building materials, and mature construction methods. However, the operational safety of earth-rock dams is lower than that of concrete gravity dams and arch dams. According to statistics, between 1956 and 2000, the number of earth-rock dam breaches in China accounted for 97.8% of the total number of breaches. Since more than 93% of my country's dams are earth-rock dams and were built in the 1950s and 1970s, they were limited by the technical and economic conditions at the time, and the engineering construction was inherently insufficient and the subsequent operation and management were not in place. Today, many dams have hidden dangers such as leakage, cracking, landslides, and termite erosion, and need to be reinforced. The regulation, reinforcement, and operation of earth-rock dams are cyclical, and generally require regulation every 20 years or so. In view of the various safety hazards of earth-rock dams, in order to reduce the safety risks brought by the long-term operation of earth-rock dams, especially to prevent disasters caused by dam breaches caused by floods during the flood season, reduce the degree of danger of reservoir dams, and at the same time to reduce the number of rectification and reinforcement times and extend the safe operation cycle of reservoirs, it is particularly necessary to improve the performance and increase the service life of traditional or conventional earth-rock dams in combination with the actual construction of projects. At present, the reinforcement method of longitudinally reinforced earth-rock dams is a widely used technology, which to a certain extent solves a series of problems that affect the safe operation of earth-rock dams, and fundamentally reduces the fatal defects of earth-rock dams such as high incidence of danger and easy dam breaches due to floods.

[0003] Specifically, the longitudinally reinforced core wall earth-rock dam refers to an earth-rock dam whose anti-seepage core wall is constructed of rigid materials. It is a new type of dam formed by building a rigid structure (i.e., a reinforcement body) that integrates anti-seepage and force-bearing properties inside a conventional earth-rock dam. The longitudinal reinforcement body is constructed by horizontally constructing slots from top to bottom near the central axis of the earth-rock dam to form slots, and then setting up steel trusses and curtain grouting steel pipes for later use, and pouring concrete in layers according to the construction method of underground continuous walls. Specifically, the bottom of the wall is generally embedded to a certain depth in the dam foundation, and finally the curtain grouting under the wall is carried out through the pre-buried grouting steel pipes in the wall to form an integral anti-seepage curtain with the dam foundation, forming a fixed end that will not deform, greatly improving the safety of the earth-rock dam (after the construction is completed, the longitudinal reinforced core wall is located inside the earth-rock dam). Although the existing longitudinal reinforced core wall method is used to maintain and improve old earth-rock dams, it has met the actual needs to a certain extent, but due to the limitations of the construction method, there are still the following technical problems. Specifically, at present, when constructing the longitudinally reinforced core wall of an earth-rock dam, the equipment involved includes, in addition to the corresponding transportation and hoisting tools, grouting tools, and excavation tools, a steel cage (steel truss) processing station, a concrete raw material yard, and a mixing station, etc.; since the crest width of an earth-rock dam is limited (generally only 3-4 meters wide), in order to facilitate construction, the existing technology uses engineering equipment to first excavate earth in the transverse section of the upper end of the earth-rock dam and transport it by vehicle, so that the width of the upper end of the earth-rock dam (the wider the width of the earth-rock dam from top to bottom) meets the construction requirements (the general conventional practice is to first excavate 3-8 meters from the dam crest and increase the width of the dam crest platform to 8-24 meters for construction); the above method requires excavation of earth and stone in advance and transportation, and after the construction is completed, the original transported earth and stone need to be backfilled in place, etc., which greatly increases the construction cost and prolongs the construction time. Therefore, the above earth-rock dam longitudinal reinforcement core wall construction method is not the optimal solution and has great disadvantages. Summary of the invention

[0004] In order to overcome the disadvantages of the existing method of longitudinal reinforcement construction in earth-rock dams due to technical limitations as described in the background technology, the present invention provides an earth-rock dam which does not require the pre-transfer of earth and stone on the earth-rock dam. Under the action of relevant mechanisms and processes, a steel cage processing station, a concrete raw material yard, a mixing station, etc. are arranged in the downstream (backwater area) of the earth-rock dam body, and the relevant materials pre-processed in the downstream of the dam body are transported to the working area on the dam body by a rail conveying mechanism, thereby reducing construction costs and reducing construction time. Equipment and a reinforced core wall construction method for the earth-rock dam are provided.

[0005] The technical solution adopted by the present invention to solve its technical problem is: The equipment for constructing the core wall of the earth-rock dam reinforcement body is characterized in that it includes a track conveying mechanism and a detection mechanism; the track conveying mechanism includes a guide tube, an electric winch, a pulley, a box, a support top rod, and an electric fixed sub-mechanism; there are at least two guide tubes, and a plurality of fixing rods are installed at the lower side ends of the two guide tubes, at least two support tubes are installed on both sides of the lower outer end of the box, and the inner diameter of the support tube is larger than the outer diameter of the guide tube, and the lower ends of the two support tubes are respectively slidably sleeved on the outer sides of the upper ends of the two guide tubes; the pulley is rotatably installed at the lower part of the front end, and a baffle is installed at the upper rear end of the two guide tubes. There are at least two supporting top rods, the upper ends of the two supporting top rods are respectively hingedly installed at the rear ends of the two guide tubes, the rear lower ends of the two guide tubes are installed with a fixed shell, the electric winch is installed in the fixed shell, and the drum wire rope of the electric winch is installed together through the pulley and the front end of the box body; there are multiple sets of electric fixed sub-mechanisms, each set of electric fixed sub-mechanisms includes a motor reducer and a spiral fixed wheel, the upper end of the spiral fixed wheel is installed at the lower end of the rotating shaft of the motor reducer, and the motor reducers of the multiple sets of electric fixed sub-mechanisms are respectively installed at the lower ends of the two guide tubes; the detection mechanism is installed in the fixed shell.

[0006] Furthermore, the distance between two sides of the lower end of the support tube is smaller than the radius of the guide tube.

[0007] Furthermore, the lower end of the supporting top rod is a pointed cone structure, the outer diameter of the spiral fixing wheel piece gradually increases from bottom to top, and the lower end is a pointed cone structure.

[0008] Furthermore, the detection mechanism includes a probe and a trigger circuit. The probe includes an insulating shell, a metal cantilever, and a metal contact rod. The upper end of the cantilever is rotatably installed at the upper end of the shell, and a metal ball is installed at the lower end of the cantilever. There are guide grooves on the front and rear sides of the shell respectively. The guide groove is located at the outer end of the shell and has a wire hole. There is a fixed screw rod in the wire hole. A contact rod is slidably sleeved in each guide groove. The shell is longitudinally distributed and installed at the upper end of the fixed shell, and the two contact rods are respectively located at the front and rear side ends of the fixed shell.

[0009] Furthermore, the trigger circuit includes an electrically connected resistor, a thyristor and an alarm, one end of the resistor is connected to the thyristor control electrode, the thyristor cathode is connected to the positive power input terminal of the alarm, the metal seat rotatably connected to the upper end of the cantilever is electrically connected to the positive power output terminal of the power module, and the outer ends of the two sliding rods are electrically connected to the other end of the resistor.

[0010] The method for constructing a reinforced core wall is characterized in that it includes the following steps: S1: installing a rail conveying mechanism between the upper and lower ends of the downstream of the earth-rock dam, and setting a steel cage processing station, a concrete raw material yard, and a mixing station at the downstream position; S2: arranging excavation equipment, hoisting equipment, and grouting equipment on the top of the earth-rock dam; S3: using the excavation equipment to horizontally excavate earth and stone on the central axis of the top of the earth-rock dam to form a core wall pit, and transporting the earth and stone by a transport vehicle; S4: processing the steel cage mechanism at the steel cage processing station, and transporting different raw materials from the concrete raw material yard to the mixing station, and the mixing station mixes each raw material to form concrete; S5: using the rail conveying mechanism to Multiple steel cages and fixed steel bars are transported to the dam top respectively, and then the multiple steel cages are placed into the core wall pit at intervals through lifting equipment, and multiple fixed steel bars are vertically inserted into the core wall pit at a certain interval; S6: Concrete is transported to the dam top through the rail conveying mechanism, and then concrete is poured into the core wall pit through the grouting mechanism, and the reinforced core wall of the earth-rock dam is formed after drying; S7: During the entire construction process, the detection mechanism monitors the position of the rail conveying mechanism. When the rail conveying mechanism sinks or tilts backward and separates from the earth-rock dam, it can alarm to prompt the staff to readjust and fix the rail conveying mechanism to prevent safety accidents when the rail conveying mechanism transports materials.

[0011] Furthermore, in step S1, after the track conveying mechanism is installed between the upper and lower ends of the downstream earth-rock dam, the lower parts of the two supporting top rods at the rear end of the track conveying mechanism are located below the ground.

[0014] Compared with the prior art, the invention has the following beneficial effects: the invention does not require a large amount of excavation and transfer of earth and stone in advance on the earth-rock dam. Under the action of relevant mechanisms and processes, the steel cage (steel truss) processing station, concrete raw material yard, mixing station, etc. are set at the downstream (backwater area) of the earth-rock dam body, and the relevant materials pre-processed at the downstream of the dam body are transported to the working area on the dam body through the rail conveying mechanism. Before the rail conveying mechanism sinks and tilts backward (especially tilts backward) and other safety accidents occur, the detection mechanism can prompt the staff to re-fix the rail conveying mechanism in time, thereby preventing safety accidents and other accidents when the rail conveying mechanism transports materials. The invention saves construction costs and reduces construction time, and has good application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

In the present invention, based on the equipment for the construction of the reinforced core wall of the earth-rock dam, the method for the construction of the reinforced core wall of the earth-rock dam 7 in combination with other equipment specifically includes the following steps. (1) The staff installs the track conveying mechanism between the upper and lower ends of the downstream of the earth-rock dam (the earth-rock dam is an inclined structure with a gradually increasing width from the upper end to the lower end, so the track conveying mechanism is in an inclined state). Specifically, the upper and lower ends of the two track conveying mechanisms are respectively located on the waterless side of the downstream of the earth-rock dam 7, and the upper end of the track conveying mechanism contacts the upper end of the rear side of the earth-rock dam 7, and the lower end of the track conveying mechanism contacts the lower end of the rear side of the earth-rock dam 7. The staff inserts the two supporting top rods 25 into the ground through other tools to stabilize the ground; then the staff turns the handle of the forward and reverse power switch S1 to one side, and multiple sets of motor reducers M (AC motor reducers M) respectively drive the spiral fixed wheel pieces 31 at the lower end to rotate clockwise, and the multiple spiral fixed wheel pieces 3 1 gradually rotates into the soil layer at the rear side of the earth-rock dam, and plays a fixing role for the track conveying mechanism as a whole (the distance between the lower end of the wire rope and the soil layer); when the subsequent construction is completed, the staff will turn the handle of the reverse power switch AS1 to the other side, and multiple sets of motor reducers M will drive the spiral fixed wheel pieces 31 at the lower end to rotate counterclockwise, and multiple spiral fixed wheel pieces 31 will gradually separate from the soil layer at the rear side of the earth-rock dam 7, making it convenient for the staff to remove the track conveying mechanism from the earth-rock dam 7; since the above operation method does not require the staff to use other equipment to fix the track conveying mechanism on the rear side of the earth-rock dam body 3, nor does it require the device for fixing the track conveying mechanism from the earth-rock dam body 3, it brings convenience to the staff and correspondingly improves work efficiency. (2) A steel cage (steel truss) processing station 4, a concrete raw material yard 5, a mixing station 6, etc. are set up in the corresponding open position downstream of the earth-rock dam 7. (3) Arrange hoisting equipment (which can be crawler-type), grouting equipment (which can be crawler-type), excavation equipment (which can be crawler-type), etc. one by one on the top of the earth-rock dam (the width of the upper end of the existing earth-rock dam 7 can fully meet the arrangement and installation of the above equipment. Specifically, the excavation equipment can be arranged first, the earth can be excavated, and then the excavation equipment can be moved away, and then the hoisting equipment and grouting equipment can be arranged. (4) The earth and stone are excavated from the top and bottom horizontally along the central axis of the earth-rock dam top by the excavation equipment and transported away by transportation vehicles. When the deep pit (core wall pit 71) reaches the depth and width, the next construction process is entered.(5) At the same time, the steel cage processing station 4 processes the steel cage mechanism (several) according to the shape of the core pit formed by the earth-rock dam after excavation, and transports the different raw materials (such as cement, sand and gravel, etc.) of the concrete raw material yard 5 to the mixing station 6. The mixing station 6 mixes the raw materials to form concrete, and then puts a plurality of steel cage mechanisms and fixed steel bars and other auxiliary parts into the box body 24 for multiple times and transports them upward to the dam top. The hoisting equipment on the dam top places a plurality of steel cage mechanisms into the core pit at intervals and welds them together with the fixed steel bars (a plurality of steel cages are welded together by a plurality of fixed steel bars, and a plurality of steel cages are welded together by steel bars, and the fixed steel bars can be vertically inserted into the lower end of the core pit 71); then, the concrete is transported into the box body 24 by a concrete delivery pump and transported upward to the dam top. At the dam top, the grouting mechanism on the dam top extracts the concrete in the box 24 to fill the concrete into the core wall pit, and after drying, forms the core wall of the earth-rock dam reinforcement body (the box needs to go back and forth several times to the lower end of the dam bottom to load concrete, and to the upper end of the dam top to extract the concrete in the box 24 through the grouting mechanism to fill the concrete into the core wall pit); specifically, the staff can control the drum of the electric winch to reel in the wire rope 29 or unwind the wire rope 29 by controlling the direction of the forward and reverse power switch A. When rewinding the wire rope 29, the wire rope rotates along the pulley to drive the box 24 to move upward toward the dam top (the box moves up or down along the support pipe 241 through the guide pipe 21), and the forward and reverse power switch A is turned off when it is in place. When unwinding the wire rope 29, under the action of the weight of the box, the wire rope rotates along the pulley to move the box 24 downward toward the dam top, and the forward and reverse power switch A is turned off when it is in place. (6) After the reinforced core wall of the earth-rock dam is dry, some earth and rock will be backfilled between the reinforced core wall and the earth-rock dam and on the top to complete the reinforcement of the reinforced core wall of the earth-rock dam.

[0022] Figure 1 , 2As shown in Figures 3 and 4, during the entire construction process, the detection mechanism monitors the position of the track conveying mechanism. When the track conveying mechanism sinks or separates from the earth-rock dam, it can alarm to remind the staff to readjust or fix the track conveying mechanism to prevent safety accidents when the track conveying mechanism transports materials. Specifically, when the track conveying mechanism does not tilt forward or backward (especially backward tilt is dangerous), the cantilever 1012 is located between the two contact rods 1013, and the 12V power supply will not trigger the thyristor VS1 to turn on through the resistor R1. Then, the buzzer B1 will not be powered on to sound, indicating that the track conveying mechanism does not tilt forward or backward. When the track conveying mechanism tilts forward or backward (more than 1 cm), the metal ball 1014 at the lower end of the cantilever 1012 (T1) contacts the front side contact rod 1013 (T2) or the rear side contact rod 1013, the 12V power supply will trigger the thyristor VS1 to turn on through the resistor R1, then the buzzer B1 will be energized and sound, indicating that the track conveying mechanism tilts forward or backward with a large arc (before using the present invention, after the track conveying mechanism is installed, the fixed shell can be opened, one or two screw rods 1016 can be loosened, and then the front or rear contact rod 1013 can be moved forward or backward along the guide groove 1015. When the metal ball is located between the inner sides of the two contact rods 1013 and the interval is a suitable distance (generally 1 cm), after tightening the screw rod, the contact rod 1013 will no longer move, thereby ensuring subsequent monitoring use). Through the above technical scheme, the present invention does not need to pre-excavate and transfer a large amount of earth and stone on the earth-rock dam. Under the action of relevant mechanisms and processes, the steel cage processing station, concrete raw material yard, mixing station, etc. are set at the downstream (backwater area) of the earth-rock dam body, and the relevant materials pre-processed at the downstream of the dam body are transported to the working area on the dam body through the track conveying mechanism. Before the track conveying mechanism sinks and falls backwards, etc., the detection mechanism can prompt the staff to readjust and fix the track conveying mechanism in time, thereby preventing safety accidents and other accidents when the track conveying mechanism conveys materials. The present invention reduces construction costs and construction time. Figure 3 As shown, the model of thyristor VS1 is MCR100-1; the resistance value of resistor R1 is 1K; the buzzer B1 is a finished active continuous sound alarm of model MF12V; the power module A1 is a finished switching power module of AC 220V to DC 12V.
