Abstract
The invention discloses a bridge guardrail base split bolt hole plugging structure which is used for solving the problems of water seepage and water leakage of split bolt hole plugging. The bridge guardrail base split bolt hole plugging structure comprises a guardrail base, wherein a hole is formed in the guardrail base, and is remained by a split bolt in the pouring process. The bridge guardrail base split bolt hole plugging structure is characterized in that a nylon plastic rod which is in excessively tight fit with the hole is embedded in the hole, an adhering agent is coated between the nylon plastic rod and the hole to form a watertight full-sealing structure. The invention also discloses a construction process of the bridge guardrail base split bolt hole plugging structure. The plugged hole does not seep and leak, and thus the problems of water seepage and water leakage of the bridge guardrail base to the split bolt hole are well solved.
Description
Technical field
This scheme is mainly used in the cast-in-place guardrail of bridge water cement concrete field, specifically a kind of structure and plugging technology that carries out shutoff for the split bolt hole in the Bridge guardrail pedestal.
Background technology
All be provided with the cast-in-place anticollision barrier of cement concrete in the bridge both sides, such as Fig. 1, in building forming process, need to use template to finalize the design, template in the general civil engineering need to use split bolt 11 that the template 12 of both sides is tightened up, play the effect of fixed form, then inside casting cement concrete.Behind the coagulation forming, again split bolt is extracted out, will be formed a hole in the position of interspersed split bolt, can be with reference to the Template Location scheme among the CN201962608U.At present, for the processing mode of split bolt hole be, use mortar with the simple shutoff of hole, this shutoff mode is suitable at general building, but has potential safety hazard for bridge and guardrail, is mainly reflected in:
In the winter time, the infiltration on road surface can progressively be accumulated in the hole, then progressively effluxes, and freeze to form the ice scraper-trough conveyer in the process that effluxes, and has caused security threat to pedestrian and the vehicle of dealing under the bridge.
Simultaneously, because the water that oozes out in the hole can form washmarking on the surface of bridge, affect the attractive in appearance of city, need to carry out thoroughly shutoff, had no at present effective shutoff scheme.
Summary of the invention
In order to solve the deficiencies in the prior art, the invention provides a kind of Bridge guardrail pedestal split bolt holes blocking structure and plugging technology, one of its purpose is carried out complete shutoff to the split bolt hole, and another purpose is to satisfy long-term non-maintaining military service.
The technical solution adopted for the present invention to solve the technical problems is: Bridge guardrail pedestal split bolt holes blocking structure, comprise Guard fence base, in described Guard fence base, be reserved with hole, this hole split bolt in casting process stays, it is characterized in that, in described hole, embed one and cross friction tight nylon plastic(s) rod, and between described nylon plastic(s) rod and hole, scribble cementing agent, form a watertight complete hermetically-sealed construction.
Described cementing agent is the neutral silicone weather-resistant glue.
Described nylon plastic(s) rod comprises straight rod section and cone rod section, and cone rod section wherein can conveniently be inserted hole, and straight rod section is crossed tight fit with hole formation.
Described nylon rod length is 150 millimeters, and is boring the rod section near making 15 millimeters to 18 millimeters gradual changes of diameter in 50 millimeters scopes of inner face.
Bridge guardrail pedestal split bolt holes blocking technique, according to the following steps operation in tandem:
Step 1 is made nylon rod, and described nylon rod has following architectural feature: described nylon rod comprises the straight rod section of outer end and inner cone rod section, and the described straight rod section of outer end matches with the size of hole;
Step 2 is cleaned out hole with hairbrush, air gun;
Step 4 uses hammer rapidly nylon rod to be wedged in the hole, until the nylon rod outer face is concordant with the pedestal external surface.
After step 4, also comprise a step of the hole mouth of wedging nylon rod being smeared the neutral silicone weather-resistant glue.
Detailed, described nylon rod length is 150 millimeters, and is boring the rod section near making 15 millimeters to 18 millimeters gradual changes of diameter in 50 millimeters scopes of inner face.
The invention has the beneficial effects as follows: the nylon plastic(s) rod has that good toughness, tear resistance are strong, oil resistant, antidetonation, stretching, bending strength are good, and have characteristics such as water imbibition is little, good stability of the dimension, the needs of the outdoor adverse circumstances of viaduct can be satisfied fully, hundred-percent shutoff can be realized.Hole after the shutoff no longer seeps water, leaks, and has well solved Bridge guardrail pedestal split bolt hole seepy question.
Description of drawings
Fig. 1 is Guard fence base cast in situs moulding figure;
Fig. 2 is the Guard fence base structural representation;
Fig. 3 is the stereogram of nylon plastic(s) rod.
Among the figure: 11 split bolts, 12 templates, 2 nylon plastic(s)s rod, 21 straight rod sections, 22 cone rod sections, 3 holes, 4 Guard fence bases.
The specific embodiment
As shown in Figure 2 to Figure 3,
The Bridge guardrail pedestal split bolt hole plugging technology that leaks was carried out the fishing expedition work in early stage before beginning to construct, mainly comprise and be familiar with design document, and carry out highway condition investigation at the scene comprehensively.Clear and definite Guard fence base split bolt hole location, quantity are also carried out detailed observed and recorded.
Then track of sealing utilizes crane gear the constructor to be delivered to guardrail outside pedestal split bolt hole location, then according to the following steps operation in tandem as construction area below bridge floor:
Step 1, make nylon plastic(s) rod 2, described nylon rod has following architectural feature: nylon rod comprises the straight rod section 21 of outer end and inner cone rod section 22, the straight rod section of outer end matches with the size of hole 3, nylon rod length is 150 millimeters, and is boring the rod section near making 15 millimeters to 18 millimeters gradual changes of diameter in 50 millimeters scopes of inner face.
Step 2 is cleaned out hole 3 with hairbrush, air gun, thoroughly removes the foreign material in the hole clean.
Step 4 uses the hammer instrument rapidly nylon rod to be wedged in the hole, until the nylon rod outer face is concordant with the pedestal external surface, the neutral silicone weather-resistant glue can form effective shutoff after solidifying.
Step 5 is smeared the neutral silicone weather-resistant glue to the hole mouth of wedging nylon rod 2.
Require Guard fence base maintenance to carry out quality inspection and evaluation according to job specfication after construction is finished, and in time the test evaluation situation is fed back to quality examination section, the problem of appearance is in time solved.
Final a kind of urban viaduct Guard fence base hole plugging structure that leaks that forms, comprise Guard fence base 4, in Guard fence base, be reserved with hole 3, in hole, embed one and cross friction tight nylon rod 2, nylon rod length is 150 millimeters, and is boring rod section 22 near making 15 millimeters to 18 millimeters gradual changes of diameter in 50 millimeters scopes of inner face.Scribble the neutral silicone weather-resistant glue between nylon rod and the hole.Form a kind of totally enclosed structure.
