[0025] The core of the utility model is to provide a prefabricated drainage ditch forming device, which can solve the defect that the existing prefabricated drainage ditch forming device can only produce prefabricated drainage ditches of the same length.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "middle", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0028] The utility model can be used for producing concrete drains, resin concrete drains or drains made of other materials.

[0029] In a specific embodiment of the present invention, Figures 1 to 6As shown, it includes a bracket assembly, an upper mold assembly, a baffle 1 and a rubber bellows 2. The cross-section of the rubber bellows 2 is U-shaped, both ends of the rubber bellows 2 are blocked and one end is provided with a faucet assembly. The bracket assembly includes a U-shaped base 3, and the rubber bellows 2 is placed in the U-shaped base 3; the upper mold assembly is installed on the bracket assembly, and the upper mold assembly includes an upper mold 4. The upper mold 4 is arranged directly above the U-shaped base 3 and is aligned with the U-shaped groove of the rubber bellows 2. The length of the upper mold 4 is greater than or equal to the length of the U-shaped base 3. An opening matching the upper mold 4 is opened on the baffle 1. Two baffles 1 are provided, and the two baffles 1 are respectively fitted with the two end surfaces of the rubber bellows 2. The U-shaped base 3 is provided with a plurality of connection structures for detachably connecting with the baffle 1, and the plurality of connection structures are arranged at intervals along the length direction of the U-shaped base 3.

[0030] Specifically, the rubber material of the rubber bellows 2 can be compounded with a reinforcing cloth layer and / or a metal mesh layer to enhance its pressure-bearing and load-bearing capacity. The water supply device arranged externally is connected to the faucet assembly and water is pumped into the rubber bellows 2, so that there is a certain water pressure in the rubber bellows 2. The pressure range can be 0.3 to 0.8 MPa, and it can also be adjusted according to the specific situation. The purpose is to try to ensure that the rubber bellows 2 will not expand and contract arbitrarily and bear the concrete or resin concrete after pouring the concrete or resin concrete. A pressure detection device, such as a pressure gauge, can be arranged on the water supply device. The pressure value displayed by the pressure gauge is the water pressure in the rubber bellows 2. The rubber bellows 2 can shrink when idle, thereby reducing the space occupied during storage. After the prefabricated drain ditch is produced, the texture on the outer surface is the reinforcing rib, but the intervals between the textures of prefabricated drain ditches of different lengths are different, which has no obvious effect on the use of the product.

[0031] The distance between the two baffles 1 is adjusted by connecting the baffles 1 with different connection structures, that is, the length of the rubber bellows 2 after being filled with water is the distance between the two baffles 1, that is, the length of the prefabricated drainage ditch. Since the length of the upper mold 4 is greater than or equal to the length of the U-shaped base 3, there is no need to replace the upper mold 4. In summary, there is no need to specially make molds of different lengths, and there is no need to replace the mold to produce prefabricated drainage ditches of different lengths, which avoids waste and reduces the investment cost of the mold, with high economic benefits.

[0032] It also includes a plurality of support plates 5, which are respectively compounded at the neck of the inner cavity of the rubber bellows 2; through holes are opened at the corresponding positions of the plurality of support plates 5 and the faucet assembly.

[0033] Specifically, the support plate 5 is a U-shaped plate that matches the inner wall of the rubber bellows 2. The multiple support plates 5 act as a skeleton to prevent the rubber bellows 2 from deforming randomly when bearing pressure and load, and to prevent the neck from bulging after filling with water, thereby ensuring that the appearance of the prefabricated drainage ditch produced is as uniform as possible. The through hole is used to connect the multiple chambers divided by the support plate 5. The neck is the attachment Figure 4 and 5 The tube wall trough 203 of the middle rubber bellows 2.

[0034] The faucet assembly includes a water inlet 201 and a water outlet 202. The water inlet 201 is arranged at the bottom of one end of the rubber bellows 2, and the water outlet 202 is arranged at the top of one end of the rubber bellows 2. There are two water outlets 202, and the two water outlets 202 are symmetrically arranged about the vertical middle plane in the length direction of the rubber bellows 2; the water inlet 201 and the water outlet 202 both penetrate the baffle 1 and are connected to valves.

[0035] Specifically, the water inlet 201 is connected to the water supply end of the water supply device, and the water outlet 202 is connected to the water return end of the water supply device. When water is pumped into the rubber bellows 2, the water flows in from the bottom, and the air inside is discharged from the water outlet 202 and enters the water supply device, and then escapes to the outside. If the external environment temperature meets the temperature for the condensation of concrete or resin concrete, the valve of the water outlet 202 is closed first after the water supply device finishes pumping water, and the valve of the water inlet 201 is closed after the water pressure in the rubber bellows 2 reaches a predetermined value. If the external environment temperature does not meet the temperature for the condensation of concrete or resin concrete, it is necessary to pump in circulating water with pressure and a certain temperature, that is, the valves of the water inlet 201 and the water outlet 202 are not closed; if the external temperature is higher than the temperature required for condensation, then the circulating water lower than the external temperature is pumped in, and if the external temperature is lower than the temperature required for condensation, then the circulating water higher than the external temperature is pumped in. The staff can adjust the temperature or flow of the circulating water according to the most appropriate setting temperature required for the specific concrete or resin concrete, so as to increase the setting speed of the prefabricated drainage ditch and improve work efficiency.

[0036] The connection structure includes a U-shaped slot 301 which is opened on the inner wall of the U-shaped base 3 . The slot 301 matches the baffle 1 . A plurality of slots 301 are distributed at both ends of the U-shaped base 3 .

[0037] Specifically, the distance between two baffles 1 can be adjusted by inserting the baffles 1 into different slots 301 .

[0038] Sealing strips are bonded to the sides and openings of the baffle plate.

[0039] Specifically, the sealing strip ensures that there will be no leakage during the pouring of concrete or resin concrete.

[0040] The bracket assembly also includes a top plate 6, which is horizontally arranged above the U-shaped base 3 through a plurality of support rods. The upper mold assembly also includes a hydraulic cylinder 7, which is vertically fixed on the top plate 6. The telescopic end of the hydraulic cylinder 7 passes through the top plate 6 and is fixedly connected to the top surface of the upper mold 4.

[0041] Specifically, the length of the prefabricated drainage ditch is usually 1 meter to 10 meters or longer. In order to ensure the stability of the lifting process of the upper mold 4, multiple hydraulic cylinders 7 can be provided. Before pouring, the telescopic end of the hydraulic cylinder 7 is extended to drive the upper mold 4 to descend until the upper mold 4 abuts against the sealing strip on the baffle 1 and then stops descending, and concrete slurry or resin concrete slurry is evenly poured into the gap between the rubber bellows 2 and the upper mold 4.

[0042] The upper mold 4 is a hollow structure.

[0043] Specifically, the hollow structure can reduce the weight of the upper mold 4.

[0044] The working principle of the prefabricated drainage ditch forming device of the utility model is as follows: before pouring, the telescopic end of the hydraulic cylinder 7 is extended to drive the upper mold 4 to descend until the upper mold 4 abuts against the sealing strip on the baffle 1 and then stops descending, and concrete slurry or resin concrete slurry is evenly poured into the gap between the rubber bellows 2 and the upper mold 4.

[0045] The water inlet 201 is connected to the water supply end of the water supply device arranged outside, and the water outlet 202 is connected to the water return end of the water supply device. When water is pumped into the rubber bellows 2, the water flows in from the bottom, and the air inside is discharged from the water outlet 202 and enters the water supply device, and then escapes to the outside. If the external environment temperature meets the temperature for the condensation of concrete or resin concrete, the valve of the water outlet 202 is closed first after the water supply device pumps water, and the valve of the water inlet 201 is closed after the water pressure in the rubber bellows 2 reaches a predetermined value. If the external environment temperature does not meet the temperature for the condensation of concrete or resin concrete, it is necessary to pump in circulating water with pressure and a certain temperature, that is, the valves of the water inlet 201 and the water outlet 202 are not closed; if the external temperature is higher than the temperature required for condensation, circulating water lower than the external temperature is pumped in, and if the external temperature is lower than the temperature required for condensation, circulating water higher than the external temperature is pumped in. The staff can adjust the temperature or flow of the circulating water according to the most appropriate setting temperature required for the specific concrete or resin concrete, so as to increase the setting speed of the prefabricated drainage ditch and improve work efficiency.

[0046] An external water supply device is connected to the faucet assembly and water is pumped into the rubber bellows 2, so that there is a certain water pressure in the rubber bellows 2. The pressure range can be 0.3 to 0.8 MPa, and can also be adjusted according to specific circumstances. The purpose is to ensure that the rubber bellows 2 will not expand and contract arbitrarily after pouring concrete or resin concrete and bear the concrete or resin concrete.

[0047] By inserting the baffles 1 into different slots 301, the distance between the two baffles 1 can be adjusted, that is, the length of the rubber bellows 2 after being filled with water is the distance between the two baffles 1, that is, the length of the prefabricated drainage ditch. Since the length of the upper mold 4 is greater than or equal to the length of the U-shaped base 3, there is no need to replace the upper mold 4. In summary, there is no need to specially make molds of different lengths, and there is no need to replace the mold to produce prefabricated drainage ditches of different lengths, which avoids waste and reduces the investment cost of the mold, with high economic benefits.

[0048] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referred to each other, and the embodiments can be combined with each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the method part.
