Description
Technical field
The present invention relates to construction engineering technical field, the reinforcing device used after especially relating to a kind of road construction cast-in-place walls core boring sampling and method.
Background technology
At present, to detect after building cast-in-situ flooring or road rehabilitation completion, core boring sampling is a kind of the most frequently used method, and it is to utilize special drilling machine and diamond hollow thin-wall drill bit, drills through the core sample of a column type for detecting test on structural concrete.The purpose of test is the detection thickness of road, comprcssive strength, integrity, density, and the intensity of concrete, structural concrete are endured cold, the degree of depth of Fire-damaged, concrete joint, quality condition, the degree of depth of distress in concrete, isolation, hole and the grating of qualification rubble at layering.Core drilling method is directly perceived, accurately, reliable, be a kind of effective ways of not replacing of other Non-Destructive Testings.But after core boring sampling, next vertical with the road surface from top to bottom and cylindrical cavity of inner wall smooth can be stayed in road surface, and existing method is to be directly injected in hole by concrete, levelling rear completion.
Chinese patent literature (day for announcing: on JIUYUE 9th, 2015, notification number: CN204626216U) discloses this utility model and relates to the perforating device that building decoration construction is special.Vehicular road surface drill core repair apparatus includes car body and the core drilling machine being sequentially located on the carriage bottom plate of car body rear, water tank, blender, cement mortar agitator tank；Described core drilling machine controls drill bit by drill bit lifting handle and moves up and down；Described water tank is provided with pipeline and is connected with drill bit；Described cement mortar agitator tank is connected with blender, is provided with Grouting Pipe below；Described Grouting Pipe be arranged over laser sensor.
What technique scheme solved is that road surface drill core repair operation is easy, and coring efficiency is high, and boring can also be repaired after completing by coring, reduces the impact caused attractive in appearance of coring road pavement, the problem that coring unites two into one with repairing two procedures.
Summary of the invention
First goal of the invention of the present invention be for solving road boring and coring after, particularly after the boring and coring of concrete road surface, vertical with road surface from top to bottom and inner wall smooth the cylindrical cavity that road surface stays is repaired, the problem increasing intensity, and a kind of simple in construction is provided, the reinforcing device of easy to operate road construction cast-in-place walls core boring sampling.
Second goal of the invention of the present invention be in order to solve building cast-in-situ flooring boring and coring after, particularly after building cast-in-situ floor end face boring and coring, stay one of cast-in-situ floor is vertical with floor face from top to bottom and the repairing of the cylindrical cavity of inner wall smooth, increase its intensity and the problem leaked, and a kind of simple in construction is provided, the reinforcing device of easy to operate building cast-in-situ flooring core boring sampling.
3rd goal of the invention of the present invention is to provide the reinforcement that a kind of road construction cast-in-place walls core boring sampling uses.
The present invention realizes its first goal of the invention and be the technical scheme is that a kind of reinforcing device building road core boring sampling, this reinforcing device and boring machine with the use of, including device body and Counterboring apparatus, described device body includes fixing body and coring body, described fixing body is coaxially set with coring body, being uniformly arranged coring tooth on described coring body, described Counterboring apparatus includes that fixing body and reaming bit, described fixing body are coaxially set with reaming bit.The reinforcing device that this road core boring sampling uses, the fixing body being provided with by a device body and coring body, fixing body is connected with boring machine, drive coring body that the road position needing detection is carried out coring by boring machine, road hole after coring is due to inwall smoother and be the hole that diameter is identical from top to bottom, unfavorable for the road repair after coring, so carrying out reaming by Counterboring apparatus on the former pertusate coaxial line of road, the hole that Counterboring apparatus is left is that a bottom diameter is identical with foramen primum hole dia, upper end diameter is a cylindrical cavity of bottom diameter 2 times.
As preferably, described reaming bit, a diameter of 105mm of opening, upper end is directly 200mm.The little upper end, structure bottom of reaming bit is greatly the needs in order to meet reinforcement.Under the effect of vehicle or external force, the cylinder after reinforcement does not sinks.
As preferably, described reaming bit, a diameter of 155mm of opening, upper end is directly 300mm.The little upper end, structure bottom of reaming bit is greatly the needs in order to meet reinforcement.
As preferably, the size of coring sample body needs according to detection and sets, but general diameter takes 100mm or 150mm.Reaming bit opening diameter the most also has 105mm or 155mm bis-kinds.
As preferably, described reaming bit opening diameter is gradually incremented by along axial line less than diameter and the bit diameter of reaming bit upper end, described reaming bit hollow, and the hole that described reaming bit is left is the cylindrical hole that little upper end, a bottom is big.
As preferably, described fixing body is cylindrical structure, and described coring body is tube structure, and described fixing body is integrally disposed upon the upper end of coring body, and described coring tooth is uniformly arranged on the opening of coring body cylinder.Such structure is for overall coring, it is ensured that Detection results.
The present invention realizes second goal of the invention and be the technical scheme is that a kind of building cast-in-situ floor face core boring sampling reinforcing device, this reinforcing device and boring machine with the use of, including device body and Counterboring apparatus, described device body includes fixing body and coring body, described fixing body is coaxially set with coring body, described Counterboring apparatus includes that fixing body and reaming bit, described fixing body are coaxially set with reaming bit.So carrying out reaming by Counterboring apparatus on the original hole of road, the hole that Counterboring apparatus is left is that a bottom diameter is identical with foramen primum hole dia, and upper end diameter is a cylindrical cavity of bottom diameter 2 times.Described cylindrical shape hole is in floor face perforate, and sky is presented herein below after perforate.After solving cast-in-situ floor end face boring and coring, stay one of cast-in-situ floor is vertical with floor face from top to bottom, and the reinforced work of the cylindrical cavity that the big bottom of inner wall smooth and upper end is little is provided with pallet arrangement.The problem leaked for cylinder periphery new and old faying face crack after solving reinforcement, the pre-buried slip casting syringe needle when reinforcement.
Realizing the technology used in the present invention method is: the reinforcement used after a kind of road construction cast-in-place walls core boring sampling, it is characterised in that: described reinforcement comprises the following steps:
(1) first the road or cast-in-place walls needing sampling is carried out drill hole sampling；Device body is connected with puncher, add water cooling and carry out punching sampling by the coring tooth on coring body, sample body on the road taken out or cast-in-place walls is cylindrical structure, a diameter of 100mm or 150mm of sample body, and the opening diameter on road or cast-in-place walls is 105mm or 155mm simultaneously；
(2) reaming: be connected with puncher by Counterboring apparatus body, adds water cooling by reaming bit reaming so that the hole bottom diameter on road or cast-in-place walls is 105mm, and upper end diameter is a cylindrical cavity of 200mm；Or by reaming bit reaming so that the hole bottom diameter on road is 155mm, and upper end diameter is a cylindrical cavity of 300mm；
(3) stirring compound: by stone, yellow sand, cement, extender, bonding agent, according to weight ratio: 3: 2: 1: 0.2: 1 mixing match becomes mixed fillers, add water stirring；
