Description
Technical Field
The invention relates to the field of construction, in particular to a quick construction method for a hard rock stratum top pipe working well.
Background
The pipe-jacking construction is a non-excavation construction method, and is a pipeline burying construction technology without excavation or with few excavations. The technology thoroughly solves the problems of damage to urban buildings, road traffic blockage and the like in pipeline burying construction, and has obvious advantages in soil stabilization and environmental protection. This is very important for cities with heavy traffic, dense population, numerous ground structures and complex underground pipelines, which will create a clean, comfortable and beautiful environment for the cities. In a hard rock stratum geological construction environment, according to a conventional construction method, a foundation pit needs to be excavated firstly, so that the construction area of the foundation pit is usually large in order to facilitate hoisting of a jacking pipe, the corresponding area excavated to a rock stratum is also large, and certain influence can be caused on the surrounding environment. In addition, because the rock stratum hardness is higher, the excavation difficulty is higher, and the construction period can be correspondingly prolonged.
Disclosure of Invention
Aiming at the defects of the prior art, the technical problems to be solved by the invention are as follows: how to provide a method for quickly constructing a hard rock stratum top pipe working well, which reduces the construction difficulty, shortens the construction period and reduces the influence on the environment.
In order to solve the technical problems, the invention adopts the following technical scheme:
a quick construction method for a hard rock stratum top pipe working well comprises the following steps:
(1) leveling the field, and positioning the position of the pile hole by measuring lofting;
(2) adopting a rotary drilling machine to perform drilling operation until the drilling reaches a specified elevation;
(3) transversely excavating and widening the pile hole bottom and the hole wall on the opposite side of the pipe jacking construction position to form a pipe jacking operation space for horizontally placing the jacking pipe, wherein the pipe jacking operation space is provided with an opening for enabling the jacking pipe to be constructed to enter the pipe jacking operation space, the width of the opening is greater than the diameter of the jacking pipe, and the height of the opening is equal to the height of the opening
Wherein c is the length of the jacking pipe, and b is the inner diameter of the pile casing;
(4) hardening the ground in the jacking operation space and the ground in the pile hole of the jacking pipe;
(5) a jacking device for jacking the jacking pipe is arranged in the jacking operation space of the jacking pipe;
(6) and transversely excavating the lower foundation layer at the bottom of the pile hole and at the position of the pipe jacking construction, and jacking the pipe jacking construction through a jacking device.
In the invention, a rotary excavating machine drilling mode is adopted, and after the pile hole drilling construction is finished, because the rock stratum has higher hardness and is not easy to collapse, the corresponding pipe jacking construction can be directly carried out at the bottom of the rock stratum. And a jacking pipe jacking operation space is dug at the bottom of the pile hole, so that the jacking pipe can be horizontally placed conveniently and jacking operation of the jacking pipe is facilitated. The jacking pipe to be constructed is lifted downwards from a pile hole orifice, the inner diameter of the whole pile casing is not large, so that the jacking pipe can only be lowered in a vertical or inclined mode with a small angle, after the jacking pipe is lowered to the bottom of the hole, the jacking pipe needs to be horizontally placed, jacking construction operation is convenient to carry out, the jacking pipe enters a jacking operation space through an opening of the jacking operation space, the height of the opening is calculated through a stranding theorem according to the maximum inclined angle of the jacking pipe in the pile casing, the bottom end of the jacking pipe is placed at the bottom of the hole and close to one side of a jacking construction opening, the jacking pipe is horizontally placed with the opening as a base point, the jacking pipe can enter the jacking operation space through the opening, and finally, the jacking construction operation is completed by excavating a rock stratum on the jacking side of the jacking pipe. Just need not excavate before the construction like this and form great foundation ditch, only need dig soon the machine creep into the stake hole can, reduced the excavation area to hard rock stratum in addition, reduced the construction degree of difficulty, construction speed obtains accelerating simultaneously, has shortened the worker period, and the great foundation ditch of corresponding construction area in stake hole has reduced the influence that causes the environment.
Preferably, the jacking pipe jacking operation space is provided with an arched top wall which is convex outwards. The jacking pipe jacking operation space can be used as a danger avoiding space for constructors, and when the jacking pipe is hung downwards, the constructors can jack the jacking pipe into the operation space, so that falling objects at high altitude are prevented from being injured by smashing. The arched top wall is convenient to construct and is not easy to collapse due to the structure.
As an optimization, in the step (3), after the construction of the jacking pipe jacking operation space is completed, spraying concrete on the inner wall of the pile hole to form a plain-shotcrete layer. Because in the whole rock stratum geology, the construction difficulty of jacking and excavating of the jacking pipe is large, the construction distance of the jacking pipe is long, the construction period is long usually, the weathering phenomenon can correspondingly occur on the wall of the pile hole after the construction period is prolonged, and the plain-blown concrete layer can protect the wall of the pile hole, so that the construction safety is improved.
In conclusion, the beneficial effects of the invention are as follows: the invention adopts a pile hole mode, reduces the construction range, correspondingly reduces the construction workload and difficulty, improves the construction efficiency, shortens the construction period and reduces the influence on the surrounding environment.
