Description

Technical Field

[0001] The invention belongs to the field of tunnel lining construction equipment, in particular to an inverted tunnel lining trolley. Background Art

[0002] After going through three stages of technological backwardness, initial development, and rapid development, China's tunnel construction has entered the fourth stage of leading the world's tunnel construction with the successful construction of a large number of large-section, full-section, long-distance, high-burial depth tunnels that cross rivers, seabeds, karst, soft and broken, high water pressure and other complex strata.

[0003] Tunnel support is generally divided into two types, namely primary support and secondary lining. Generally speaking, Class I surrounding rock does not require primary support, while other surrounding rock requires primary support. Whether secondary lining is required is determined by the geological conditions of the area where the tunnel is located and the design purpose of the tunnel.

[0004] For non-prefabricated secondary lining of tunnels, the construction methods are generally divided into two types: full-section one-time lining and separate lining of side arch and invert. In the full-section lining construction, a needle-beam trolley is used to divide the trolley front section, trolley section, and rear section into three relatively independent areas, and heavy equipment such as vehicles cannot pass through the trolley. The construction method of separate lining of side arch and invert can choose the construction method of invert trestle + fixed formwork with heavy trucks passing according to project needs, or choose other construction methods that do not have heavy trucks and equipment passing. Common invert construction methods include manual finishing, fixed formwork, sliding formwork, etc.

[0005] The methods commonly used to control the finished surface in tunnel invert lining construction include manual finishing, fixed formwork, slipform, invert trestle + fixed formwork, needle beam trolley, etc. The characteristics of different construction methods are as follows:

[0006] Manual finishing is suitable for small-scale lining or post-lining repair. The construction speed is slow, the finished lining surface is difficult to uniformly control, and the effect is poor, but it is the lowest cost for small and micro tunnels.

[0007] The fixed formwork is suitable for construction projects with small height difference of the finished surface of the invert, small concrete side pressure, and small engineering volume. After the lining of the fixed formwork is completed, a large degree of repair work is often required, which is not conducive to the construction of inverts in large areas, long distances, and complex surrounding environments.

[0008] The slipform construction method is currently the most widely used in tunnel invert lining construction. However, for large or super-large tunnel invert lining construction, the friction between the invert concrete and the slipform is large, resulting in a large scale of slipform traction equipment. Especially when the height difference of the tunnel invert surface exceeds a certain degree, it is difficult to ensure the effect of the tunnel invert surface after forming, and the workload of later repair is also large.

[0009] The inverted arch trestle + fixed formwork is suitable for projects that still need to maintain the tunnel traffic capacity during the invert construction process. Its use effect is good, but the length of the inverted arch trestle is often the same as the casting position (several times the length of the inverted arch formwork, and the equipment cost of the invert casting will increase exponentially).

[0010] For large or extra-large cross-section tunnels, compared with the existing invert lining construction method, the full-section needle beam trolley has the strongest applicability and good effect. However, due to the complex structure of the core needle beam structure, large size and weight, its cost is often several times higher than the equipment price used in the construction method of separate casting of invert + side top arch. At the same time, the full-section needle beam trolley has a complex structure, and its production, transportation, installation, use, and disassembly are all difficult.

[0011] The construction of tunnel invert lining adopts different construction methods and selects different construction equipment according to its cross-sectional size, rock characteristics, project construction period, technical capabilities of construction companies or personnel, etc. However, for large-section or extra-large-section tunnels, the choice of construction method for invert construction is often limited by existing construction equipment, installation sites, transportation channels, etc., resulting in high construction costs or poor construction results.

[0012] Compared with several lining methods such as manual finishing, shaped formwork, and slipform, an inverted tunnel lining trolley improves the construction speed and construction effect. Compared with an inverted arch trestle + shaped formwork, a needle beam trolley, etc., it greatly reduces the cost of construction equipment while ensuring the same construction speed and construction effect, avoids the problems of construction sites and transportation channels required for the installation of large equipment in tunnels, and provides a new idea and solution for tunnel invert lining construction.

[0054] The support system includes an upper support shoe 3-1, a lower support shoe 3-2, a first hydraulic cylinder 3-3 and a second hydraulic cylinder 3-4; the first hydraulic cylinder 3-3 and the second hydraulic cylinder 3-4 are respectively fixed on the upper and lower sides of the rectangular frame, the movable end of the first hydraulic cylinder 3-3 is connected to the upper support shoe 3-1, and the movable end of the second hydraulic cylinder 3-4 is connected to the lower support shoe 3-2. An anti-slip plate 3-5 is provided at the end of the lower support shoe 3-2.

[0055] A lower support shoe 3-2 is provided at the bottom of the front end of the skeleton system, and a guide wheel 3-6 is provided at the end of the lower support shoe 3-2. A lateral auxiliary plate 1-5 is provided between the transverse main beam 1-1 and the longitudinal main beam 1-2. A pull ring 1-4 is provided at the end of the skeleton system, which is used to connect the pulling device to the pull ring 1-4 mobile trolley. A fourth hydraulic cylinder 5-5 is provided on the longitudinal slide rail beam 1-3, and the movable end of the fourth hydraulic cylinder 5-5 is connected to the movable trolley 4-1, and the fourth hydraulic cylinder 5-5 is used to adjust the position of the movable trolley 4-1. A hydraulic pump station 5-3 is provided at the upper end of the skeleton system, and the hydraulic pump station 5-3 is used to adjust the working state of the hydraulic cylinder. It also includes a vertical support 6-1 for a pedestrian passage, a horizontal support 6-2 for a pedestrian passage, a ladder vertical rod 6-3 and a ladder cross rod 6-4; the vertical support 6-1 for a pedestrian passage and the ladder vertical rod 6-3 are fixed at the bottom of the skeleton system, and the ladder vertical rod 6-3 and a plurality of ladder cross rods 6-4 are fixed to form a ladder; the bottom of the ladder vertical rod 6-3 is fixedly connected to the horizontal support 6-2 for a pedestrian passage, and a passage springboard 6-5 is arranged at the top of the skeleton system. A top aisle 5-2 is arranged at the top of the skeleton system, and an inspection port 5-1 is arranged on the top aisle 5-2. The hydraulic cylinder platform 5-4 is used to place the fourth hydraulic cylinder 5-5.

[0056] After the trolley is fixed to the set position, the position of the movable trolley 4-1 is adjusted by adjusting the fourth hydraulic cylinder 5-5 fixed on the longitudinal slide rail beam 1-3, so that the template system connected to the movable trolley 4-1 is adjusted to the designed position.

[0057] After the formwork system is adjusted to the position, the formwork system is fine-tuned by adjusting the third hydraulic cylinder 4-4 of the hydraulic leveling system to accurately adjust the formwork system to the designed position.

[0058] When the trolley moves, the formwork system is placed on the finished concrete surface by adjusting the third hydraulic cylinder 4-4, retracting the first hydraulic cylinder 3-3 and the second hydraulic cylinder 3-4. At this time, the formwork system supports the upper structure of the trolley through the movable trolley 4-1, and then the trolley is stepped forward by mechanically pulling the pull ring 1-4.

[0059] After the trolley steps into place, the second hydraulic cylinder 3-4 is adjusted to support the lower support shoe 3-2 on the rock wall, and the anti-slide plate 3-5 increases the friction between the trolley and the rock wall, thereby improving the stability of the trolley.

[0060] The first hydraulic cylinder 3-3 is adjusted so that the upper support shoe 3-1 is also supported on the rock wall. Then the first hydraulic cylinder 3-3 and the second hydraulic cylinder 3-4 are adjusted at the same time to adjust the trolley frame system to the designed position and fix it firmly.

[0061] After the trolley is fixed, the third hydraulic cylinder 4-4 is adjusted to lift the entire formwork system off the ground. At this point, the trolley has completed a complete walking and working process.

[0062] When there is not enough space on the ground, in order to ensure the normal use of the trolley, the trolley is fixed at the upper position of the tunnel by the lower support shoe 3-2; in order to prevent the trolley and the tunnel rock wall from sliding relative to each other, an anti-slip plate 3-5 is added to the end of the lower support shoe 3-2; in order to prevent the trolley from overturning or becoming unstable during use and transfer, the relative position of the trolley is fixed by the upper support shoe 3-1, and the trolley is securely fixed by adjusting the first hydraulic cylinder 3-3 and the second hydraulic cylinder 3-4.

[0063] To ensure that the template can be accurately adjusted to the designed position, a horizontal adjustment system is set up by adjusting the fourth hydraulic cylinder 5-5, and a vertical adjustment system is set up by adjusting the third hydraulic cylinder 4-4. At the same time, each unit of the template has a total of 4 hydraulic cylinders available for vertical adjustment, ensuring that the template can be accurately adjusted to the designed position.

[0064] In order to solve the problem of the trolley stepping, the trolley frame system and the template system are relatively independent. When the trolley moves, the template system is fixed, and the trolley frame system is moved to the specified position through mechanical traction. When the trolley is working, the frame system is fixed, and the template system is moved to the designed working position by adjusting the movable trolley, hydraulic cylinder, etc.

[0065] The trolley skeleton system is divided into the main load-bearing components at the rear and the guide frame part at the front. When the trolley moves, the guide frame and guide wheels 3-6 drive the overall movement of the trolley skeleton system under the action of the traction machinery. After the trolley moves into place and is fixed, the template system is adjusted by adjusting the hydraulic cylinder.

[0066] The device solves the problems of tunnel invert lining construction channel and construction space, and greatly reduces the difficulties in the design, transportation and installation of large-scale tunnel invert construction equipment. It has the characteristics of good construction effect, fast construction speed, simple production, convenient installation and easy operation. It saves a lot of labor costs and greatly reduces the difficulty and cost of equipment production and installation. It provides a new construction equipment and construction method for tunnel invert lining construction. It has strong practicality and obvious economic benefits.
