Description

Laser integrated device and tunnel waterproof gasket auxiliary positioning device

Technical Field

The utility model relates to the field of tunnel construction equipment, in particular to a laser integration device and a tunnel waterproof gasket auxiliary positioning device.

Background

The waterproof and drainage construction in tunnel construction is a very critical process, but because the popularization of the current mechanical automation in the construction of medium and small tunnels is low, most tunnel waterproof boards are laid by adopting a self-made waterproof trolley and a manual method, and waterproof gaskets are laid by manual visual positioning. Such operation is extremely nonstandard, does not have the directionality and also does not have unified distance promptly, makes the waterproof board hang and establishes not have the direction reference, and the fixed point position that the interval is different simultaneously also makes the waterproof board lay very irregularity, consequently greatly reduced the standardization that the waterproof board was laid, reduced tunnel water-proof effects.

Adopt artifical waterproof construction's tunnel at present, all use the power actuated setting device to wear waterproof packing ring to fix geotechnological cloth on tunnel primary tributary face earlier, adopt self-control fixed dimension's "cross reinforcing bar" or only rely on the position that naked eye controlled waterproof packing ring, the packing ring of laying out like this causes the position in disorder because the error accumulation, can not hang for waterproof board after and establish and provide the direction reference, lead to the waterproof board to hang and establish the fold phenomenon that appears in the in-process easily, the waterproof board overlap joint is not in the same direction as straight, the swell, reduce water-proof effects, influence later stage lining steel reinforcement.

In order to standardize and accurately lay the waterproof gaskets, in the prior art, a total station is adopted for orientation, then a manual pull ruler is adopted or a standard rope is used for marking each gasket point position in detail, and then the waterproof gaskets are arranged on the marked point positions.

Specifically, the key of the whole process is to mark a tunnel direction line on the tunnel wall by using a total station, taking a side wall as an example, as shown in fig. 1 (tunnel gradient x%), firstly measuring points a, then measuring points a 'at intervals of 10 to 12 meters, and requiring that the relative heights of the points a' and a in the tunnel are consistent. And measuring the point B within a range of two meters below or above the point A, and requiring the mileage of the point B to be consistent with that of the point A. Measuring a point B 'at a distance of 10 to 12 meters from the point B, and requiring the relative heights of the point B' and the point B in the tunnel to be consistent; thus AB and A 'B' are always perpendicular to the tunnel axis and AA 'and BB' are always parallel to the tunnel axis.

And drawing straight lines between points A and B, A 'and B', punching waterproof gaskets at intervals of f/2 to be respectively used as points c, d, e, c ', d' and e ', then drawing straight lines between points c, c', A, A ', d', B, B ', e and e', and punching waterproof gaskets at intervals of f, so that regular waterproof gaskets with the direction parallel to the axis of the tunnel can be punched on the wall of the tunnel.

Before the waterproof coiled material is laid, the coiled material is expanded along the circumferential direction of the tunnel, as shown in fig. 2 (the gradient x% of the tunnel), one long edge gi or hj of the coiled material is parallel to the AB or A 'B', and the AB and the A 'B' are always vertical to the axis of the tunnel, so that the waterproof coiled materials gh and ij are also always vertical to the axis of the tunnel, and the coiled material can be laid regularly along the wall of the tunnel. Because the coiled material is parallel with tunnel axis direction, can guarantee that the coiled material is all the time with tunnel wall hugging closely, under the smooth-going prerequisite of tunnel primary tributary face, common defects such as bulge stagger joint can not appear in waterproofing membrane, also need not repair the coiled material of laying yet, can effectively keep apart water behind the arch wall lining cutting.

However, when the total station is used for measurement and positioning, the whole process is complicated, and rapid construction cannot be achieved.

Some embodiments of the utility model are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

In a first aspect, the present invention provides a laser integrated device, as shown in fig. 3, including a connecting rod 1 and a plurality of laser lamp sets 2; the laser lamp set 2 comprises a plurality of laser spot lamps 3, and the light rays of the laser spot lamps 3 in the same laser lamp set 2 are on the same plane; the laser lamp group 2 is arranged on the connecting rod 1 and is used for enabling the laser spot lamp 3 to project light spots on the inner wall of the tunnel to form a light spot matrix.

Specifically, in this embodiment, a plurality of groups of laser lamp groups 2 are connected together through a connecting rod 1 to form an integral laser integration device 5, the laser spot lamps 3 in each group of laser lamp groups 2 are projected onto the tunnel wall 7 to form a light spot matrix on the tunnel wall 7, and the positioning of the fixing position of the waterproof gasket is realized through the light spot matrix.

Specifically, in this embodiment, when the plurality of laser spot lamps 3 in the laser lamp set 2 are arranged, an included angle between two adjacent laser spot lamps 3 may be different, so as to make the projection distances of the adjacent laser spot lamps on the tunnel wall 7 the same.

Specifically, in the present embodiment, the distances between the adjacent laser lamp sets 2 are the same, so that the spots formed when the laser spot lamps 3 project onto the tunnel wall 7 form a spot matrix.

In this embodiment, laser lamp group 2 still includes the mount pad, and laser shot-light 3 is all fixed to be set up on the mount pad for a plurality of laser shot-lights 3 form a whole through the mount pad.

When the waterproof gasket is used, the laser spot lamps 3 in the laser lamp groups 2 project on the tunnel wall 7 to form a light spot matrix, each light spot in the light spot matrix is the position of the waterproof gasket, the setting position of the waterproof gasket is found conveniently, and the position positioning of the waterproof gasket is realized.

In an alternative embodiment, the number and the irradiation direction of the laser lamps 3 in the laser lamp group 2 arranged at intervals are the same.

Specifically, in this embodiment, as shown in fig. 3, the number of the laser spot lamps 3 in the laser lamp sets 2 arranged at intervals is the same, and the number of the laser spot lamps 3 in the adjacent laser lamp sets 2 is different, so that the positioning positions of the waterproof gaskets are crossed to a certain extent, and the stability of the waterproof gaskets can be increased.

In an alternative embodiment, the laser lamp sets 2 are slidably arranged on the connecting rod 1, and the distance between the adjacent laser lamp sets 2 can be adjusted.

In this embodiment, the laser lamp group 2 is slidably disposed on the connecting rod 1, so that the position of the connecting rod 1 in the laser lamp group 2 is adjustable, and the laser integration device 5 can be suitable for different tunnel walls 7, and can be matched with different waterproof gasket setting modes.

Specifically, in this embodiment, the sliding arrangement may be that a sliding hole is provided on the mounting seat of the laser lamp set 2, the mounting seat is sleeved on the connecting rod 1 through the sliding hole, or a sliding groove is provided on the connecting rod 1, so that the mounting seat can slide in the sliding groove.

It should be noted that there are many sliding arrangements on the connecting rod 1 in the laser lamp set 2, which may be the above two arrangements, or other sliding arrangements, as long as the sliding on the connecting rod 1 in the laser lamp set 2 is realized.

Specifically, C, D, E, F four groups of laser lamp sets 2 are arranged on the connecting rod 1, and the laser lamp sets 2 can adjust the distance between each other through sliding; the laser spot lamps 3 on the four groups of laser lamp sets 2 are divided into seven rows of k, l, m, n, o, p and q, each row of laser spot lamps 3 is fixed on a longitudinal connecting rod 1, the angle of each row of laser spot lamps 3 can be adjusted by adjusting the rotation of the connecting rod 1, and after the projection points of the laser spot lamps 3 are projected to the primary support surface, the distance of each row of laser projection on the wall of the tunnel arch can be adjusted by adjusting the angle of each row of laser spot lamps 3; c, E groups in the four groups of laser spot lamps 3 are arranged in the same row, D, F groups are arranged in the same row, and C, E and D, F laser spot lamps 3 are arranged in a staggered mode.

In an alternative embodiment, as shown in fig. 7, the connecting rod 1 is made of an elastic material.

In a strict sense, after a first waterproof gasket is arranged on the arch wall of the tunnel opening, the positions of the other waterproof gaskets of the tunnel are fixed together, and because the position of each gasket arranged behind the waterproof gasket is calculated relative to the position of the gasket arranged in front of the waterproof gasket, the laser positioning device is used for marking the position of the designed gasket, and whether the marking is accurate or not is directly related to the design of the device.

The laser integration device 5 mounted on the mobile gantry 4 is affected by the horizontal position deviation generated when the mobile gantry 4 travels and the vertical elevation deviation generated by inverted arch construction, so that the position of the laser lamp group 2 in the laser integration device 5 is changed, and the position of a light spot projected to an arch wall is deviated.

In view of the above, the projection position of the laser spot on the arch wall can be directly adjusted by indirectly adjusting the angle of the laser spot lamp 3. The size of the angular adjustment is positively correlated with the offset distance of the mobile gantry 4.

Every row of laser spot lamps 3(k, l, m, q) are respectively fixed on the same connecting rod 1, if rigid connecting rod 1 is used, the adjustment angles of the laser spot lamps 3 before and after the moving rack 4 are consistent, and the requirement that the offset distance of the front and back positions of the moving rack 4 is inconsistent cannot be met, so that the connecting rod 1 is made of an elastic material capable of generating uniform plastic deformation in consideration, and the laser spot lamps 3 on the connecting rod 1 can be projected to an arch wall to form a straight line all the time through uniform deformation.

Before leaving the factory, the laser integration device 5 calculates or uses a CAD loft by using a formula according to the size of the mobile rack 4 to obtain the offset angle of each row of the corresponding laser spot lamps 3 at one end of the mobile rack 4 under various position offset conditions, so that a functional relation can be simply formed, and if the variables are the H value (lateral offset) and the G value (elevation offset) of the mobile rack 4, the obtained values are the angle change values of each row of the laser spot lamps 3(k, l, m and q), namely the angle values (G, H value ranges are-20 cm to +20cm) of each row of the laser spot lamps 3 needing rotation adjustment, and the functional relations of the two ends of the device are the same.

In actual application, G, H values before and after the movable rack 4 are actually measured on site and are respectively input into the device controller, the device automatically searches the set rotation angles of the laser spot lamps 3 in each row according to the input variable values, and the angles of two ends of the laser spot lamps 3 in each row are automatically adjusted through the precise angle controller.

The deviation correction design corrects the deviation of the laser point position, the visible G, H physical axis is changed into the invisible G, H parameter, the size of the device is reduced in the physical space, the influences of collision and the like possibly caused to the device in the space range by field construction are reduced, and the device is more effectively adapted to the narrow space environment of a tunnel.

In a second aspect, the present invention provides a tunnel waterproof gasket auxiliary positioning device, as shown in fig. 4 and 9, comprising a mobile platform 4 and a laser integration device 5 according to any one of the foregoing embodiments; the laser integration device 5 is provided on the moving stage 4.

Connecting rod 1 along the tunnel vertically with laser integrated device 5 is fixed on moving rack 4, because of moving rack 4 is for weight reduction, all uses light steel skeleton to add fretwork wire net processing, consequently installs the laser banks 2 on moving rack 4, and most light spots all can put in to the tunnel wall through the wire net space.

In consideration of the influence of field construction, the laser integrated device 5 is arranged at the middle position of the top layer of the mobile platform frame 4, so that construction collision can be effectively avoided, shielding of the tunnel ventilation pipe 12 is avoided, and the range of the laser lamp set 2 can cover the whole arch wall.

Before installation, tunnel survey personnel perform lofting through measuring points of the total station, mark a tunnel midpoint I point and a tunnel midpoint J point on an inverted arch surface in front of the mobile rack 4, and calculate the deviation between the actual elevations of the midpoint I point and the tunnel midpoint J point and the design values.

Before the tunnel is used, the number of the laser lamp sets 2 in each laser integrated device 5 to be additionally installed and the number of the laser spot lamps 3 in each laser lamp set 2 are calculated through the size of the cross section of the tunnel, and if the arc length of the cross section of the primary support of the tunnel is 25m, the length of each lining is 12m, and the distance between waterproof gaskets is 80cm, the number of rows of the laser spot lamps 3 to be additionally installed is 25/0.8 and approximately equals to 31 rows, namely 31 rows of light spots can be irradiated through the arrangement of the laser spot lamps 3 in the laser lamp sets 2; the number of the laser lamp sets 2 on each laser integrated device 5 is 12/0.8-15. The distance between the adjacent laser lamp groups 2 on each laser integrated device 5 can be set to be 80 cm/group when the laser integrated devices 5 are produced, the angle of each row of laser lamps can be set according to lofting when the laser lamps in each row are assembled in a factory, and the laser lamps are rechecked by using a measuring tool after being installed on a construction site.

After the laser integrated device 5 is installed, the power supply is turned on, the number of the lasers projected to the arch wall is counted, if the number of the lasers projected to the arch wall can reach 80%, the using effect is not affected, and the vacant point positions can be measured by using simple measuring tools such as a ruler.

For the point position projected to the arch wall, a measuring group uses a total station to measure whether the circumferential and longitudinal points are on the same straight line or are vertical or parallel to the center line of the tunnel; for the lasers in the same row, whether laser points form a straight line after being connected is mainly measured, whether the relative elevations of the laser points are consistent, and whether the linear distance of each point meets the design requirement; for the circular laser, whether the mileage values of all laser points in the tunnel are consistent or not and whether the circular or linear distance of all the points meets the design requirements or not are mainly measured.

According to construction experience and multiple measurement results on site, the elevation difference between K points and L points and M points and N points on two sides of the same mileage position of the same set of inverted arch is not more than 10cm, the elevation difference between the I point and K, L points on two sides and between the J point and M, N points on the center position is not more than 5cm, and the influence of CAD lofting analysis on projection points is taken as an example that the maximum deviation value between the middle point and the side edge is 5 cm.

Because the laser integrated device 5 is arranged near the center line of the tunnel, the elevation error of the laser integrated device 5 only influences the distance between two rows of lasers close to the two sides of the center line, and the laser row distances of other parts are unchanged; as shown in FIG. 5, CAD lofting analysis shows that when the elevation of the device is changed by 5cm, the distance between two rows of laser beams at the arch top is increased or decreased by 2.8cm at one side, and is increased or decreased by 3.5cm at one side, so that the distance between the fixed points of the waterproof plate required by technical guidance for waterproof and drainage construction of railway tunnels is preferably 0.5-0.8 m of the arch, and the technical requirements for waterproof and drainage construction of tunnels are met.

In an alternative embodiment, as shown in fig. 6, the moving gantry 4 is further provided with an adjusting device 6; the adjusting device 6 is connected with the laser integrating device 5 and is used for adjusting the position of the laser integrating device 5.

After the laser integration device 5 is installed, a power supply is turned on, the number of lasers projected to the arch wall is counted, if the projected point positions are insufficient, the installation position of the equipment can be finely adjusted, so that the laser integration device 5 moves upwards and is fixed at a position slightly larger than r/2; the positions of all groups of laser lamps C-F on the device can be uniformly moved for 3-5 cm to the front or the back of the movable rack 4, so that the laser projected by the laser spot lamp 3 is prevented from being shielded by the upright post of the movable rack 4, and the number of the projected laser is counted again until the number of the projected laser is more than 80%.

In an alternative embodiment, the adjustment means 6 comprise a vertical adjustment bar 8 and a horizontal adjustment bar 9; the vertical adjusting rod 8 is fixedly arranged on the movable rack 4; the horizontal adjusting rod 9 is arranged on the vertical adjusting rod 8 in a sliding mode, and the horizontal adjusting rod 9 can move on the vertical adjusting rod 8 in the vertical direction; the laser integration device 5 is arranged on the horizontal adjusting rod 9, and the laser integration device 5 can move on the horizontal adjusting rod 9 in the horizontal direction.

In the embodiment, after the moving stage 4 is in place, the 0 scribed lines on the vertical adjusting rods 8 at the Q end and the R end of the device are respectively aligned with the R/2 position of the moving stage and are firmly fixed, and simultaneously, the laser integration device 5 is rotated to adjust the level bubble arranged on the laser lamp set 2 to the middle position, so that the laser spot lamp 3 reaches the preset position.

In an alternative embodiment, the vertical adjustment lever 8 and the horizontal adjustment lever 9 are provided with a scale.

In the embodiment, marking lines of-20 to +20 are marked on the longitudinal adjusting rod and the transverse adjusting rod respectively, which respectively indicate that the device can meet the requirement that the error of the construction elevation of the inverted arch is +/-20 cm and the error of the walking center line of the movable rack 4 is +/-20 cm; when the actual value of the elevation of the inverted arch is lower than the design value, the actual value is represented as negative (-) and the actual value is higher than the design value, the actual value is represented as positive (+), the tunnel is forward from the driving direction, and when the center line of the movable rack 4 deviates to the right side of the center line of the tunnel, the actual value is positive and when the center line deviates to the left side of the center line of the tunnel, the actual value is negative.

Assuming that the deviation of the mark height of the point I is-5 cm, the deviation of the central line of the front end of the movable stand 4 is +6cm, the deviation of the mark height of the point J is +5cm, and the deviation of the central line of the rear end of the movable stand 4 is-4 cm; after the two ends of the device Q, R are fixed, the G axis at the Q end of the device needs to be shifted to the +5cm position of the scale, the H axis needs to be shifted to the-6 cm position of the scale, the G axis at the R end of the device needs to be shifted to the-5 cm position, and the H axis needs to be shifted to the +4cm position, so that the device is located on the parallel line of the center line of the tunnel.

The laser integration device 5 mainly relates to the self-correction of the transverse inclination deviation and the transverse positioning deviation of the laser lamp set 2 in the aspect of automatic upgrading; the automatic correction of the inclination deviation can be realized by additionally arranging an automatic identification instrument for the position of the leveling bubble on the laser lamp group 2 and arranging a horizontal posture adjusting motor, so that the motor is linked with the leveling identification instrument to ensure that the laser box is in a horizontal state at any time;

the horizontal positioning deviation can be respectively provided with a driving motor on a vertical adjusting rod 8 and a horizontal adjusting rod 9 of the device, and the position of the device 6 is automatically adjusted by inputting the offset of the front and rear central lines of the movable rack 4 and the construction error of an inverted arch through a manual handheld control box.
