Description

Technical Field

[0001] This utility model relates to an insulated shed, and more particularly to a novel insulated shed for a slurry-water balance pipe jacking working pit. Background Technology

[0002] Slurry-balanced pipe jacking is a pipe jacking construction technique that utilizes a slurry-balanced pipe jacking machine. During construction, a mixture of clay, other additives, and water of a specific density, viscosity, and pressure is supplied to the slurry chamber behind the cutterhead of the pipe jacking machine through an inlet pipe. This mixture forms a mud film on the excavation surface, and the pressure of the slurry in the chamber balances the soil pressure and groundwater pressure on the excavation surface. Simultaneously, the soil and sand cut by the cutterhead are transported back to the pit surface as slurry through a mud discharge pipe. In some extremely cold regions of my country (such as Heilongjiang and Inner Mongolia), winters are long, typically lasting from early November to mid-April, with temperatures remaining below freezing for up to six months. Slurry-balanced pipe jacking is primarily a wet operation; excessively low temperatures can negatively impact the operation of machinery, reducing its lifespan. For example, bentonite pipes, whose ends are connected entirely by rubber hoses, experience reduced hardening and toughness at low temperatures, making them prone to cracking during bending and causing bentonite leakage. This leads to a drop in internal pressure, preventing normal operation. In the extremely cold weather of the north, temperatures generally drop below -20℃ after winter begins, especially at night, which affects the operation of diesel-powered machinery and reduces work efficiency. Furthermore, the low temperatures also have a negative impact on people, leading to reduced work efficiency. Pipe jacking pits are typically set up every 100-200 meters.

[0003] Traditional insulation methods simply involve covering the working pit with a plastic film, supporting it with iron pipes in the center, and then nailing the iron pipes to the ground or fixing them with other tools. This method has poor insulation performance, and it is not easy to reuse the equipment when changing to other working pits. It also requires repeated erection and is quite cumbersome to retrieve and place equipment in the working pit. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a new type of heat-insulating shed for slurry-water balance pipe jacking working pits, which has a simple structure, good heat preservation effect, is reusable, and improves construction efficiency.

[0005] This utility model discloses a novel heat-insulating shed for a slurry-water balance pipe jacking working pit, comprising a support device and a heat-insulating device. The support device is a support frame composed of several support rods, and a sliding skylight is provided on the top of the support frame and slidably connected thereto. The heat-insulating device is wrapped around the support frame and has an opening for the sliding skylight.

[0006] This utility model discloses a novel heat-insulating shed for a slurry-water balance pipe jacking working pit, wherein the top of the support frame is provided with a first slide rail and a second slide rail, and the sliding skylight is provided with pulleys, and the sliding skylight slides on the first slide rail and the second slide rail via the pulleys.

[0007] This utility model discloses a novel heat-insulating shed for a slurry-water balance pipe jacking working pit, wherein a limit rod is provided between the first slide rail and the second slide rail to limit the position of the sliding skylight.

[0008] This utility model discloses a novel heat-insulating shed for a slurry-water balance pipe jacking working pit, wherein the heat-insulating device includes heat-insulating cotton and heat-insulating plastic film, with the heat-insulating cotton sandwiched between two layers of heat-insulating plastic film.

[0009] This utility model relates to a novel heat-insulating shed for a slurry-water balance pipe jacking working pit, wherein the support frame is provided with an entrance / exit on its side.

[0010] This utility model relates to a novel heat-insulating shed for a slurry-water balance pipe jacking working pit, wherein the support rod is a steel pipe, and the first and second slide rails are I-beam steel rails.

[0011] The difference between this utility model and the prior art is that this utility model uses a heat preservation device wrapped on the support frame to keep the mechanical equipment in the pit and the mud pool on the ground warm. In order to facilitate the removal and placement of equipment from the pit, a sliding skylight that can be slidably opened and closed is provided on the top of the support frame, and a door for workers to enter and exit is provided on the side of the support frame. It not only has a good heat preservation effect, but also facilitates the removal and placement of equipment and the entry and exit of workers.

[0012] This utility model provides a novel heat-insulating shed for a mud-water balance pipe jacking working pit, which includes at least the following beneficial effects:

[0013] The new type of insulated shed, which is slightly larger than the opening of the working pit, can be reused in multiple working pits on the construction site without repeated assembly. It can be moved by crane, which enhances construction efficiency. The sliding skylight on the top of the insulated shed and the door on the side not only facilitate the loading and unloading of equipment and the entry and exit of workers, but also have a certain degree of airtightness, which enhances the insulation effect of the new type of insulated shed.

[0022] like Figure 1 , 2 As shown, the present invention provides a novel heat-insulating shed for a slurry-water balance pipe jacking working pit, comprising a support device 01 and a heat-insulating device 02. The support device 01 is a support frame 11 composed of several support rods. A sliding skylight 14 is provided on the top of the support frame 11 and is slidably connected thereto. The heat-insulating device 02 is wrapped around the support frame 11 and has an opening in the sliding skylight 14.

[0023] The support frame 11, assembled from support rods, is rectangular, but can also be other shapes. However, the rectangular support frame 11 has a simpler structure and is easier to assemble. The number of support rods is not specifically limited here. Several support rods are connected to each other by bolts or welding to form the support frame 11 structure. The size of the support frame 11 depends on actual needs and is not specifically limited here. During project construction, multiple working pits have roughly the same opening area. The support frame 11 is assembled according to the size of the working pit opening area. After assembly, it can be reused during the construction of multiple working pits, improving construction efficiency.

[0024] like Figure 1 As shown, a sliding skylight 14 that can slide along the length direction (i.e., left and right direction) of the support frame 11 is installed on the top of the support frame 11. A first slide rail 12 and a second slide rail 13 are provided on the top of the support frame 11. A pulley 15 is provided on the sliding skylight 14. The sliding skylight 14 slides on the first slide rail 12 and the second slide rail 13 through the pulley 15.

[0025] The first slide rail 12 and the second slide rail 13 are connected to the top of the support frame 11 by welding or bolting and are parallel to each other. Both slide rails are provided with sliding grooves. The sliding skylight 14 is rectangular, but can also be other shapes. The rectangular shape facilitates cooperation with the two straight slide rails (i.e., the first slide rail 12 and the second slide rail 13) to enhance the airtightness of the new type of heat preservation shed. Figure 4 As shown, the sliding sunroof 14 is equipped with pulleys 15 on both the front and rear sides. The number of pulleys 15 is not specifically limited here. Three or more can be installed on each side to reduce the friction between the sliding sunroof 14 and the slide rail, thereby enhancing the smoothness of the sliding sunroof 14. The sliding sunroof 14 slides on the top of the support frame 11 by sliding between the pulleys 15 and the two slide rails. The sliding sunroof 14 is also equipped with a handle 17 for pushing it to move.

[0026] The insulation device 02 is tied to the support frame 11 by cable ties or steel wire (i.e. wrapped around the support frame 11). The insulation device 02 has a skylight opening at the position of the sliding skylight 14 that is slightly smaller than the area of ​​the sliding window, which facilitates the opening and closing of the sliding skylight 14 and enhances the insulation effect of the insulation device 02 on other positions of the support frame 11.

[0027] When in use, the new type of insulation shed is hoisted to the working pit by a crane and placed above the working pit. It is then fixed with ground anchors or bolts to prevent it from being affected by natural factors such as strong winds. The new type of insulation shed covers the working pit and the mud pool next to it, keeping the equipment and personnel in the working pit and the mud-water mixture in the mud pool warm. It ensures that the internal temperature of the new type of insulation shed is not lower than 0℃. If necessary, a warm air blower can be added in the pit for secondary insulation to ensure the stable operation of all mechanical equipment and prevent the mud-water mixture from freezing.

[0028] When it is necessary to retrieve or place equipment into the working pit, pull the handle 17 on the sliding skylight 14 at the top of the new type of insulated shed to open it. At this time, the relevant equipment can be lifted out or placed into the working pit by a crane. After the retrieval or placement is completed, pull the handle 17 on the sliding skylight 14 to close the sliding skylight 14.

[0029] The sliding skylight 14 can be sealed with glass or transparent plastic, or with insulation material or other materials with the same effect, to enhance the airtightness and insulation of the insulated shed.

[0030] like Figure 4 As shown, a limit rod 23 is provided between the first slide rail 12 and the second slide rail 13 to limit the position of the sliding sunroof 14.

[0031] Both ends of the first slide rail 12 and the second slide rail 13 are connected by welding or bolts to limit rods 23. The limit rods 23 restrict the position of the sliding sunroof 14 and ensure that the sliding sunroof 14 will not derail.

[0032] When the sliding sunroof 14 is open, pull the handle 17 on the sliding sunroof 14 to the left to move it to the left until it contacts the left end limit rod 23. At this time, the sliding sunroof 14 is fully open. When the sliding sunroof 14 is closed, pull the handle 17 on the sliding sunroof 14 to the right to move it to the right until it contacts the right end limit rod 23 between the two slide rails. At this time, the sliding sunroof 14 is fully closed.

[0033] With this configuration, the top of the new type of insulated shed remains sealed during the opening and closing of the sliding skylight 14 (i.e., there is no gap between the sliding skylight 14 and the insulation device 02 on the top plane), thereby enhancing the insulation effect of the new type of insulated shed.

[0034] like Figure 5 As shown, the heat preservation device 02 includes heat preservation cotton 21 and heat preservation plastic film 22, with the heat preservation cotton 21 sandwiched between two layers of heat preservation plastic film 22.

[0035] The insulation cotton 21 is wrapped inside the insulation plastic film 22 (that is, the insulation cotton 21 is sandwiched between two layers of insulation plastic film 22), which can increase the insulation effect of the new type of insulation shed on the one hand; on the other hand, the insulation plastic film 22 also plays a certain role in heat insulation; in addition, the surface of the insulation plastic film 22 is smooth, corrosion-resistant and wear-resistant, and plays a role in wind and snow protection, thereby extending the service life of the insulation device 02 and the new type of insulation shed.

[0036] like Figure 3 As shown, the support frame 11 has an access door 16 on its side.

[0037] The doorway 16 can be set on any side of the support frame 11. The doorway 16 can be a single door or a double door, used for workers to enter and exit and to move small equipment. At the position of the insulation device 02 corresponding to the doorway 16, a door curtain structure adapted to the size of the doorway 16 is set. While facilitating workers to enter and exit, it can effectively block heat loss and increase the insulation effect of the new insulation shed.

[0038] like Figure 1 As shown, the support rod is made of steel pipe, and the first slide rail 12 and the second slide rail 13 are I-beam steel rails. The support rod uses 50-type steel pipe, which has good compressive and bending resistance. On the one hand, this ensures that the new insulation shed has sufficient weight and strength to withstand the impact of natural factors such as strong winds; on the other hand, it increases the sturdiness of the new insulation shed. The first slide rail 12 and the second slide rail 13 use 280-type I-beam steel rails, which have good bending resistance and can withstand large bending moments. Furthermore, the I-beam steel rails have I-beam grooves, and the pulleys 15 of the sliding skylight 14 slide within these grooves, ensuring that the sliding skylight 14 will not derail and enhancing the stability of the new insulation shed.
