Description

Pattern foundation pit supporting structure supporting beam rope saw cut method for dismounting
Technical field
The present invention relates to a kind of rope saw cut method for dismounting, specifically pattern foundation pit supporting structure supporting beam rope saw cut dismounting side Method.
Background technique
In Deep Foundation Pit Supporting Project, especially in the deep area of mud, in order to guarantee deep basal pit safety, elongated setting steel Reinforced concrete supporting beam, during basement construction, supporting beam need to be with being removed in the work progress of basement structure.It passes The foundation pit method for dismounting of system be pneumatic pick cut, the methods of static(al) explosion, there are effects it is low, noise is big, fugitive dust is more the disadvantages of, and tear open It needs largely manually to be cleared up after removing, it is long in time limit.
Summary of the invention
The present invention is directed to overcome the deficiencies of existing technologies, a kind of pattern foundation pit supporting structure supporting beam rope saw cut method for dismounting is provided, Execute-in-place is convenient, is easily understood;Small to structural perturbation, cutting speed is fast, high-efficient;It can be increased according to supporting beam reasonable quantity The quantity of rope saw, is not limited by place and space, reduces labor waste.
In order to solve the above-mentioned technical problem, the present invention is implemented as follows:
A kind of pattern foundation pit supporting structure supporting beam rope saw cut method for dismounting, it is characterised in that it includes the following steps:
Step 1: it is reinforced during Construction Support beam lower layer's floor using form bracing system, in mould after construction Plate support system top casting concrete floor;
Step 2: preparation of construction: power supply, water source laying in place, are determined pit retaining monitoring point by scene;
Step 3: the big of cutting cube is determined according to the elevating capacity of hanging device, the concrete section for tearing support scheme and supporting beam open Small, weight and per pass cut surface position draw cutting design typesetting figure, and pull cutting line on beam;
Step 4: steel stirrup is placed under supporting beam, and rectangular sleeper is padded between steel split heads and the supporting beam that need to be cut;
Step 5: the cutting line position pulled according to scene puts rope saw well, and diamond rope saw and rope saw and supporting beam are connected It connects;
Step 6: powering on, cooling water, checks debugging rope saw and fail-safe condition, tears support periphery open and carries out security warning Mark;
Step 7: after confirmation reaches and tears stay part open, starting to cut, after per pass supporting beam the first block concrete block is due to cutting The mode for having stress release, therefore inclined-plane being taken to cut off being capable of smooth handling after guaranteeing cutting;
Step 8: the concrete block for cutting completion is lain in the support platform of steel split heads and rectangular sleeper composition, with tower crane or Crane be hoisted to outside the venue, when concrete block is not within tower crane or crane radius, shipped it to and is hung using fork truck It transports in radius, then carries out handling.
The beneficial effects of the present invention are: can reduce noise compared to method, static(al) blasting procedure is cut using the method and dust is dirty Dye, the concrete block of cutting, which is allocated and transported, reduces the expense cleared up in place and time to being crushed outside the venue;Execute-in-place side Just, it is easily understood;Small to structural perturbation, cutting speed is fast, high-efficient;The number of rope saw can be increased according to supporting beam reasonable quantity Amount, is not limited, less labor waste by place and space, and mechanization degree is high;Saw equipment of restricting is simple, is easily installed.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the structural schematic diagram of Fig. 1 side-looking direction.
Specific embodiment
As shown in Figs. 1-2: a kind of pattern foundation pit supporting structure supporting beam rope saw cut method for dismounting, it includes the following steps:
Step 1: it is reinforced during Construction Support beam lower layer's floor according to the form bracing system 1 of calculating, construction finishes Casting concrete floor 2 is carried out on form bracing system top afterwards;
Step 2: preparation of construction: power supply, water source laying in place, are determined pit retaining monitoring point by scene;
Step 3: the big of cutting cube is calculated according to the elevating capacity of hanging device, the concrete section for tearing support scheme and supporting beam 5 open Small, weight and per pass cut surface position draw cutting design typesetting figure, and pull cutting line on beam;
Step 4: the steel stirrup 3 made with 10# channel steel is placed under supporting beam, position and spacing according to tear open support scheme into Row is placed, and the rectangular sleeper 4 of 150 × 150mm is padded between steel split heads and the supporting beam that need to be cut 5;
Step 5: the cutting line position pulled according to scene puts rope saw 6 well, by diamond rope saw 7 and rope saw 6 and support Beam 5 connects;
Step 6: powering on, cooling water, checks debugging rope saw 6 and fail-safe condition, tears support periphery open and carries out security warning Mark;
Step 7: after confirmation reaches and tears stay part open, starting to cut, after per pass supporting beam the first block concrete block is due to cutting The mode for having stress release, therefore inclined-plane being taken to cut off being capable of smooth handling after guaranteeing cutting;
Step 8: the concrete block for cutting completion lies in the support platform of steel split heads 3 and the rectangular sleeper composition of 150 × 150mm On, be hoisted to outside the venue with tower crane or crane, when concrete block is not within tower crane or crane radius, utilizes fork truck It ships it in handling radius, then carries out handling.
