Abstract
A concrete combination face secondary grouting device comprises a grouting main pipe and a slurry returning main pipe which form a U-shaped loop which is embedded in late pouring block concrete, and a plurality of grouting branch pipes are arranged on the slurry returning main pipe. One end of each grouting branch pipe is connected with the pipe wall of the grouting main pipe in a sealing mode, the other end is the outlet end inserted into a slurry collecting hole, and a plastic film wraps the outlet end. The slurry collecting hole is a hole formed in the early pouring block concrete and penetrates the concrete combination face to stretch into the early pouring block concrete, and a plurality of slurry discharging grooves are engraved in the pipe wall of each grouting branch pipe at the outlet end. Secondary grouting can be conducted successfully in the embedded grouting pipes in the concrete. The grouting device is simple in structure, convenient to operate and capable of effectively guaranteeing construction quality.
Description
Technical field
The utility model relates to a kind of concrete joint surface provisions for grouting, and being applicable to needs to carry out the back-grouting device that secondary is filled with again between concrete in mass bonding surface.
Background technology
Bonding surface between concrete in mass, after backfill grouting, joint grouting etc. finish, is subject to the various factors such as differential settlement, variations in temperature, and the bonding surface after grouting likely can open again, now needs that bonding surface is carried out to secondary and fills with again.During due to once grouting, easily make slurries be filled into and be close in the pre-buried back-grouting system of bonding surface along bonding surface, cause back-grouting pipeline blockage; Therefore, conventional construction method is: the grouting pipeline that secondary is filled with again is not embedded in inside concrete in advance, but holes to bonding surface in the gallery arranging at structural concrete, utilizes the aperture grouting being drilled with.Adopt in this way construction, not only difficulty of construction is large, and grout hole is difficult to evenly accurately lay, and grouting effect is undesirable, and also easily destroys the functional structure such as cable, the pipeline part that is embedded in inside concrete when bore operation.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of concrete joint surface back-grouting device, and this device is embedded in concrete, can meets the needs of bonding surface back-grouting.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of concrete joint surface back-grouting device, comprise grouting supervisor and overfall supervisor, after grouting supervisor and overfall supervisor composition " U " shape loop are embedded in, water in block concrete, overfall supervisor is provided with multiple grouting arms; One end of grouting arm and overfall supervisor's tube wall is tightly connected, and the other end is the port of export, and the port of export is inserted in poly-slurry hole, and at this port of export place parcel plastic foil; Poly-slurry hole is that the boring of formerly watering on block concrete is set, and it extend into and first water in block concrete through concrete joint surface; On grouting arm, be carved with many slurry outlet grooves, slurry outlet groove one end is positioned at the port of export of grouting arm, and the other end extends to outside poly-slurry aperture, hole.
The port of export of described grouting arm leaves gap with at the bottom of poly-slurry hole, hole.Poly-slurry hole forms by adopting rig formerly to water the mode of holing on block concrete.
Gap between outer wall and the concrete joint surface of described grouting arm adopts cement paste sealing, and while avoiding being in the milk for the first time, slurries enter in grouting arm, guarantee that the pipeline of this device is unobstructed.
The degree of depth in described poly-slurry hole is 8-12cm.This poly-slurry hole depth is moderate, neither can be because of too deeply affecting pulp and occurring plug-hole, and also can when being built, concrete not come off by collision grouting arm because of too shallow.
Slurry outlet groove on described grouting arm is 4, and is evenly distributed on grouting arm, and the length of slurry outlet groove is exposed poly-slurry aperture, hole 2-5cm.The general grout cell that adopts in traditional method, while being in the milk for the first time, grout cell is stopped up, after seam face opens again, if grout cell is not to be on the seam face opening, grouting pipeline just cancels, so can not carry out back-grouting, the utility model is by setting out stock tank, can ensure that seam face opens again time, between grouting pipeline and concrete seam face, there is passage.
The length of described grouting arm is 25-35cm; And the distance between two grouting arms is 1.2m left and right.
Grouting supervisor and overfall supervisor are the supervisor who adopts DN32 steel pipe to make, and grouting arm is the grouting arm that adopts DN25 steel pipe to make.
The method that adopts above-mentioned concrete joint surface back-grouting device to construct, concrete operating procedure is: be responsible for into slurry by grouting, slurries enter respectively each grouting arm along overfall supervisor, slurries in grouting arm break through plastic foil, the slurry outlet groove of slurries from grouting branch pipe wall flows out, be filled to concrete joint surface to be in the milk, reach the object of back-grouting.
A kind of concrete joint surface back-grouting device that the utility model provides, by above-mentioned structure, can successfully realize on inside concrete pre-embedment grouting pipe road and carry out back-grouting, the problem that the grouting effect of avoiding the mode that adopts well cementing to bring is undesirable, easily destroy inside concrete built-in fitting.This apparatus structure is simple, easy and simple to handle, can effective guarantee construction quality.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A face sectional view of Fig. 1.
Detailed description of the invention
As shown in Figure 1-2, the utility model is a kind of concrete joint surface back-grouting device, comprise grouting supervisor 1 and overfall supervisor 2, after grouting supervisor 1 and overfall supervisor 2 composition " U " shape loops are embedded in, water in block concrete 3, overfall supervisor 2 is provided with multiple grouting arms 4; One end of grouting arm 4 and overfall supervisor's 2 tube wall is tightly connected, and the other end is the port of export, and the port of export is inserted in poly-slurry hole 6, and at this port of export place parcel plastic foil 7; Poly-slurry hole 6 is for arranging the boring of formerly watering on block concrete 5, and it extend into and first water in block concrete 5 through concrete joint surface 8; On grouting arm 4, be carved with many slurry outlet grooves 10, slurry outlet groove 10 one end are positioned at the port of export of grouting arm 4, and the other end extends to outside poly-slurry 6 apertures, hole.The port of export of described grouting arm 4 leaves gap with at the bottom of poly-slurry 6 holes, hole; Leave the space of back-grouting; This gap is generally 3cm left and right.Gap between described grouting arm 4 and concrete joint surface 8 adopts cement paste 9 to seal; While preventing that after-pouring block concrete 3 from building, concrete slurry stops up poly-slurry hole 6 and the grouting arm 4 of this device; Slurry outlet groove 10 on described grouting arm is 4, and is evenly distributed on grouting arm, and the length of slurry outlet groove 10 is exposed poly-slurry aperture, hole 2-5cm.
