Description
Technical field
The utility model relates to a kind of infrastructure construction device, particularly a kind for the treatment of apparatus for rainwater box culvert.
Background technology
In recent years, along with the fast development of national infrastructure construction, the a large amount of underground transportation facilities in various places starts to build or set up, in the route selection, work progress of urban subway station, inevitable needs pass through built rainwater box culvert, therefore, the rainwater box culvert conflicted with foundation ditch just need can carry out space enclosing structure trenching construction and concreting through manually abolishing, after shutoff.Workman carry out rainwater box culvert abolish with shutoff during, space enclosing structure groove section inwall is in and faces dummy status, the vibrations of abolishing period will cause disturbance to inwall soil, this just need to seek a kind of can for workman provides interim supporting to ensure the personal safety of workman while abolishing rainwater box culvert.
The trend generally needing the rainwater box culvert processed is all intersect with large-angle with the trend of foundation ditch, now conventional rainwater box culvert method of abolishing has two kinds: the first, for the rainwater box culvert that buried depth is more shallow, and in the venue portion's conditions permit when, put slope excavation, backfill again after rainwater box culvert processes into; The second, to the box culvert darker with buried depth, usually set steel sheet pile in box culvert both sides, carry out putting slope in the direction being parallel to foundation ditch trend, then carry out soil excavation, rainwater box culvert abolishes and the shutoff of rainwater box culvert, but all there is drawback in above way, first method is higher to site requirements, and the subway work overwhelming majority is in inner city, busy city, and enclosing takes up an area difficulty, be difficult to reach and put slope requirement, take a risk not carry out putting slope process by force and will cause great threat to safety of workers; And the second situation construction period is longer, lease, the construction of steel sheet pile expend larger, need to add inner support under partial picture, sometimes also do not possess and move towards to being parallel to foundation ditch the condition that the direction soil body puts slope, take a risk not carry out putting slope process by force and will cause great threat to safety of workers.
Utility model content
The purpose of this utility model is to provide temporary support device during a kind of rainwater box culvert process, solve the technical problem of lack of space during the process of rainwater box culvert, for the constructor of process rainwater box culvert provides safe and reliable working space.
For achieving the above object, the utility model adopts following technical scheme:
Temporary support device during a kind of rainwater box culvert process, comprise two pieces be parallel to each other and the identical baffle plate of structure, be connected horizontally on one group of internal overarm support between two pieces of baffle plates and be connected to the side plate of two pieces of baffle plate both sides, on the dual-side of described baffle plate corresponding have level, for the support draw-in groove of connected support structure, have in the middle part of the base of baffle plate vertical, for connecting the box culvert draw-in groove of rainwater box culvert.
Described baffle plate has hole for hoist.
Described side plate has hole for hoist.
The height dimension that the width dimensions that the width of described box culvert draw-in groove is greater than rainwater box culvert is 10 ~ 20cm, the degree of depth is greater than rainwater box culvert is 10 ~ 20cm.

Detailed description of the invention
Embodiment is see shown in Fig. 1, Fig. 2, Fig. 3, temporary support device during this rainwater box culvert process, comprise two pieces be parallel to each other and the identical baffle plate 1 of structure, be connected horizontally on one group of internal overarm support 3 between two pieces of baffle plates 1 and be connected to the side plate 2 of two pieces of baffle plate 1 both sides, on the dual-side of described baffle plate 1 corresponding have level, for the support draw-in groove 6 of connected support structure 7, have in the middle part of the base of baffle plate 1 vertical, for connecting the box culvert draw-in groove 5 of rainwater box culvert 8; Described baffle plate 1 has hole for hoist 4.
Shown in Figure 4, for using state figure of the present utility model, described box culvert draw-in groove and rainwater box culvert joint are each up and down puts 5 ~ 10cm outward, and namely the width of box culvert draw-in groove 5 is greater than the height dimension that the width dimensions of rainwater box culvert is 10 ~ 20cm, the degree of depth is greater than rainwater box culvert is 10 ~ 20cm; Width 15 ~ the 20cm of described support draw-in groove 6, height 15 ~ 20cm, concrete size can be determined according to backing material used.
Baffle arrangement can determine according to the rainwater box culvert width that need process and monolithic steel plate width, general site operation be the steel plate that 20mm is thick, 2m is wide, and when the width of rainwater box culvert is more than 2m, plurality of steel plates can be welded to each other is stitched together as baffle plate, but during splicing, the side of every block plate has all needed support draw-in groove, and height of baffle plate is determined according to box culvert buried depth, the baffle plate of internal overarm support both sides need be welded to connect with profile steel inner support bar, and baffle plate and side sheet room need welding mutually.
Described internal overarm support can be the shaped steel such as channel-section steel, i iron or angle steel, and specifically can determine according to job site material, weld seam is considered according to lifting requirements, and this internal overarm support later stage can be used as the upper and lower current ladder of workman, should be noted internal overarm support direction during welding.
Described hole for hoist for directly to punch on baffle plate, and punch position, according to this temporary support structures Weight computation, meets lifting requirements.
Described support draw-in groove cuts and forms above baffle plate, the lifting of this temporary support device is to assigned address, the braced structures such as shaped steel or the lumps of wood is adopted to prop up temporary support device according to result of calculation, need during the material selection of braced structures to consider workman's weight, be braced structures 7 with i iron in the present embodiment, by i iron with lead wall 9 and be connected.
Work progress of the present utility model, concrete steps are as follows:
Step one, construction leads wall, bottom then box cut section to rainwater box culvert;
Step 2, measure box culvert elevation of bottom, box culvert width, groove section width, according to excavating buried depth, top buried depth and width determination box culvert draw-in groove at the bottom of rear rainwater box culvert and supporting the position of draw-in groove and make temporary support device: box culvert draw-in groove distance box culvert both sides 5 ~ 10cm need be ensured; Support draw-in groove after braced structures such as the insertion lumps of wood or shaped steel etc., need assurance device to lift and do not contact box culvert end face to assigned address; Note needing correct welding up and down according to workman during internal overarm support welding; Hole for hoist chooses correct position according to the weight of temporary support device, ensures that position of opening is in the wide point midway of monolithic steel plate; Notice during lifting that rainwater box culvert will be aimed in the position of box culvert draw-in groove.
Step 3, lifts this temporary support device, inserts support draw-in groove to fix this temporary support device position after reaching assigned address by the braced structures such as the lumps of wood or shaped steel.
Step 4, constructor by internal overarm support bottom rainwater box culvert, abolish rainwater box culvert, and enter box culvert inside and carry out shutoff.
Step 5, completes shutoff, is hung out by this temporary support device, carries out as required storing, recycle or cutting.
