Abstract
The utility model relates to a detachable emergency cover plate which comprises a steel plate, a valve arranged at the middle part of the steel plate, and two pulling rings arranged on the steel plate. The detachable emergency cover plate also comprises at least one expansion bolt arranged on two sides of the steel plate, which are larger than a region to be excavated, wherein one circle of water stop rubber strip is arranged at the outer side of the expansion bolt and below the steel plate. The detachable emergency cover plate has the advantages that a special region of an underwater structure can be rapidly plugged once water burst occurs; compared with emergency measures such as chemical grouting and rapid freezing, the detachable emergency cover plate can be used for rapidly and effectively plugging the place where the water burst occurs at the first time, thus the dangerous case is prevented from being enlarged; and the detachable emergency cover plate is simple in structure, is convenient for installation, is lower in cost, and is suitable for maintenance of the underwater structure.
Description
Technical field
The utility model relates to the underground engineering construction technical field, relates in particular to a kind of emergent structure of cover plate.
Background technology
When the maintenance underground structure; The outer wall that often needs the interim specific region of destroying underground structure is to carry out all kinds of maintenances (for example on underground structure boring to carry out operation such as slip casting); This situation that has underground water to pour in underground structure often takes place; Danger is bigger, if deal with improperly, can cause great engineering accident.Present emergency measure mainly contains chemical grouting, quick freezing etc., but these measures need large-scale professional equipment; Implementing all needs the regular hour; Can not often cause the expansion of dangerous situation, and these measures be with high costs in that the just enforcement immediately of the water burst very first time takes place.
Summary of the invention
The utility model technical issues that need to address have provided a kind of dismountable emergent cover plate, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme:
The utility model comprises: steel plate; Described steel plate middle part is provided with a valve and steel plate is provided with two draw rings; Also comprise: on described steel plate, at least one expansion bolt also is set greater than the both sides in excavation zone; Under the outside of described expansion bolt, steel plate, also be provided with a circle watertight rubber bar.
Compared with prior art, the beneficial effect of the utility model is: carry out quick blocking in the time of can water burst taking place in the underground structure specific region, compare chemical grouting; Emergency measures such as quick freezing should can carry out shutoff to the water burst place in the very first time that water burst takes place by anxious cover plate, fast effectively; Avoided the expansion of dangerous situation, and simple in structure, easy for installation; Cost is lower, is applicable to the maintenance of underground structure.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
Visible by Fig. 1: the utility model comprises: steel plate 1; Described steel plate 1 middle part is provided with a valve 2 and steel plate 1 is provided with two draw rings 3; Also comprise: on described steel plate 1, at least one expansion bolt 4 also is set greater than the both sides in excavation zone 6; The outside, steel plate at described expansion bolt 4 also are provided with a circle watertight rubber bar 5 for 1 time.
Before the underground structure excavation; Quick cement levelling is carried out in zone in underground structural excavation zone and the regional certain limit of distance excavation; Cement levelling zone is greater than the emergent projection of cover plate on underground structure fast; On the concrete slab of the underground structure of several the pairing positions of bolt hole on the emergent cover plate, squeeze into expansion bolt (if underground structure is a steel work, then several bolts of welding on the steel member of the underground structure of several the pairing positions of bolt hole on the emergent cover plate).
If in digging process, run into the situation of water burst, then the nut on the expansion bolt is taken off, grasp the draw ring on the emergent cover plate; The cover plate of will meeting an urgent need moves on the excavation zone; Bolt hole is aimed at prior mounted expansion bolt, be installed to nut on the expansion bolt again and tighten, emergent cover plate is installation; Watertight rubber bar meeting water-swellable is enclosed in one of the outer setting of bolt, reaches the purpose of water blockoff.
Run into water burst need install should the process of anxious cover plate in, if the phreatic hydraulic pressure of gushing out is excessive, emergent cover plate will bear very big power and be difficult to fix; This moment can be with the valve open that is provided with on the cover plate of meeting an urgent need, and water is gushed out from valve, has reduced the power that emergent cover plate bore greatly; Make emergent cover plate be easy to install; After the emergent cover plate installation with valve closing with sealing, through should also can chemical grout being injected the excavation zone through valve by anxious cover plate to excavating regional slip casting.After the danger of water burst is removed, the nut on the expansion bolt is backed out, can should get off by anxious detachable cover plate.
